Tomodachi Islands

Tomodachi Islands (known as Tomodachi Collection: More Islands in Japan) is the 3rd installment of the Tomodachi series and a sequel to Tomodachi Life. It was released on the Nintendo Switch worldwide on May 1, 2023. It is similar to its predecessor but also includes new features.
An enhanced port for the Nintendo WS was released on June 21, 2023.
==Save files==
Unlike the predecessor, this game allows the player to create up to 15 save files per profile, meaning up to 120 save files per Switch in total. Each save file has its own progress and save files can interact with each other in the same way that two Switches can through either a local connection or Nintendo Switch online. Each save file can also have any game mode.
When choosing a save file, the player gets to see the following information:
*Island name
*A picture of the main island with all unlocked locations in the current season and time of day
*Mii count (not counting Miis that count towards the other counters)
*Baby count (only including babies who have not yet grown up, after which they become regular Islanders or travelers)
*Traveler count
*Banishment count (non-death speed mode only)
*Death count (death mode only)
*Mosquito count (non-death mode only)
* Game mode (with icons)
*Time and date
*Island Level
* Island Task process (percentage)
Features:
*When playing, the player can choose to save their progress on a new save file, creating two save files that were the same up to a certain point. However, the new island gets a new address and all travelers are only connected to the original save file.
*Each save file can be set into a different time period. However, regardless of the set time, a save file is still able to send export items and explorers from other save files.
*Wuhu Island looks the same on all save files at the same time. The only difference in its appearance is the time of the day, which varies depending on the time on the save file.
* In real-time mode, problems with negative consequences if ignored that were present when the game was last saved have their timers reset the next time the player opens the save file. In speed mode, the time left for all problems remains the same as it was when the game was last saved.
==Game modes==
Save files can be given a mode that is chosen when it is played for the first time. Once selected, it cannot be changed for the specific save file.
Normal mode (the default) is used to refer to real-time mode with no additional game modes.
Death mode is only available as DLC.
===Time modes===
====Real-time mode====
Normal mode is the mode most similar to the game play of the previous Tomodachi games. When starting normal mode, the player has to set a starting date and time and create their lookalike. Time works like in real life.
====Speed mode====
When starting speed mode, the player must set a starting date and create a starting population of at least 8 Miis. While other stats of the Mii can still be changed afterwards, in speed mode, a Mii's age cannot be changed afterwards.
Time flows more quickly in this mode. The player can control the flow of time, with the slowest and default option being one day per ten minutes (approximately one year per hour) and the fastest being one day per second (approximately ten years per hour). The player can also pause time and explore different locations with time paused, though no new problems can appear and Miis do not change locations while time is paused. Time also pauses whenever the player is not on the main map or an area with homes.
In speed mode, Miis live in apartments and houses like in normal mode, as well as space apartments once unlocked. Many of the normal problems are absent while friendship and love problems are more frequent. Relationship age restrictions work differently, as now only Miis who are 18 or older can date. Due to the faster pace, problems happen more frequently and locations take less time to unlock.
The children of two Miis stay in their parents' house until they turn 2, which is when they gain their own apartments.
Unlike normal mode, a Mii's appearance automatically changes when they age, but can be manually changed back.
Miis are banished from the island when they turn 100. They still appear on the Mii list after this but do not count to the Mii limit. Because of this, a Mii's age cannot be set as 100 or more in this mode unless death mode is also activated (in which case the maximum age is 119).
===No romance mode===
In this mode, Miis cannot get into a relationship, and as such, some of the features of normal gameplay are changed. Mii Homes are still available, as they can be unlocked by having a Mii prove they can live on their own without marrying. The unlocking requirements of Leisure Island locations have also been changed due to the lack of romantic interactions in this mode. The game can still technically acknowledge a relationship between two Miis of they are manually set as the parents of a third Mii, but in gameplay, the two treat each other like they would any other unrelated Miis.
In Mii creation, the gender preference and species preference options are absent. The romance and soulmate main interests are also unavailable, as they focus on romantic relationships.
No romance mode can only be used if the time is set as real-time mode.
==Mii creation==
When adding a new Mii, the player can choose to start from scratch, select a Mii from the Switch, previously played Switch game or another save file, or find Miis online if the player has a Nintendo Switch Online membership. The player can change any traits of the Mii unless the player received the Mii online with editing disabled.
Anything about the Mii can be changed afterwards unless specified otherwise. Sometimes, however, relationships limit what can be changed, such as gender preference, gender, age and relation. Many things can, however, be changed to almost whatever even then by going through multiple steps (for example, a dating Mii's gender can be changed by having the other Mii's gender preference set as both).
The maximum number of Miis per save file is 600 (not counting explorers).
===Mii's appearance===
The first thing the player does when creating a Mii is selecting its appearance. The player can use all features included in the Mii Maker in the Nintendo Switch version of Miitopia. 
Other species have all customization options which humans have, along with some extra features.
*Aliens have the option of having antennas as well as more than two eyes.
*Elves have the option of having visible ears.
* Vampires have fangs in every mouth, along with an option to choose whether they are visible or not when the mouth is closed (this option is not available for every mouth). Even if the fangs are not visible while the mouth is closed, they become visible when the vampire opens their mouth.
==== Species====
By default, Miis are humans. However, later in the game, different species for Miis are unlocked. They act the same way as normal Miis but have different appearances and some other changes. Each species has an exclusive level up gift. A Mii's species cannot be changed afterwards, with the only exception being the change of the player's lookalike's species (however, the default locations will remain unchanged). 
*Alien (Unlocked by unlocking Space Apartments): Aliens start out in Space Apartments and when they receive 10,000 money, they get an apartment on the regular island (Earth) as well. Aliens are less likely to like old-fashioned products and more likely to like space themed products. They are also more likely to prefer space food over Earth food. Their exclusive level up gift is the UFO, which allows them to fly around locations.
*Elf (Unlocked by TBA): Elves start out in Mii Apartments like humans but have their exclusive default interior. If they ever move to Mii Homes, their home will look more fancy as well. Elves donate more money and are more likely to hang out at the fountain. Elves are less likely to like cheap products and more likely to like fancy products. Their exclusive level up gift is the bow and arrow, which they use for archery.
*Vampire (Unlocked by TBA): Vampires start out in Mii Homes and their home is a spooky mansion. A vampire can get an apartment by completing tasks to prove they are capable of living with humans. Vampires rarely go outside and never sleep. Vampires are less likely to like food and more likely to like spooky products. Their exclusive level up gift is the rent-a-bat coupon, which allows a bat to visit their apartment or home.
===Information===
After choosing a Mii's appearance, the player gets to add information about the Mii. All features from Tomodachi Life return, but there are also added features. Features with * next to them are required to be manually filled (other fields have default options which can be changed, or can be left empty).
*Gender*: This affects the way a Mii's default clothes and default interior look like. Male and female Miis are less likely to like clothes specifically designed for the opposite gender. Options for gender are male and female.
*First name*
*Middle names: A Mii can now have up to 3 middle names.
*Last name*
*Name order: The player can now choose whether the last name appears first or last. Last by default.
*Nickname*: Nicknames now allow up to 20 characters instead of 10.
*Favorite color*: This will change the color of the Mii's regular clothes. There are now more favorite colors available than before. Miis are more likely to like certain clothes if they're in the Mii's favorite color.
*Date of birth*: A Mii's date of birth can be set anywhere between January 1 in the year 1 and the current date. Setting full dates of birth is now mandatory. If a Mii with a date of birth in the future is added, the year of birth is changed to the current year or the previous year depending on the birthday (or up to 4 years ago if the day of birth is a leap day). In speed mode (without death mode) and death mode, the maximum ages are one day less than 100 and one day less than 120, respectively, and any Miis who would otherwise be older are changed to have the maximum age instead (or up to 4 years less than the maximum age for leap day birthdays). The maximum ages are not present for vampires or elves.
*Age group*: There are now more age groups available than before. Different age groups have different features. Age groups are automatically determined based on the date of birth.
** Toddler (0-2 years old): If set as a child of someone living in Mii Homes, they will live in their parents' home as well. However, they will also get their own apartment and can't be made into travelers.
**Young child (3-6 years old): Goes to preschool.
**Child (7-12 years old): Goes to school the year after they turn 7 and can ask the player to help them with their homework as a problem.
**Teenager (13-19 years old): Goes to school until the end of the year they turn 19 and can ask the player to help them with their homework as a problem.
**Young adult (20-29 years old): Can go to work.
** Adult (30-44 years old): Can go to work with a higher chance of being promoted compared to young adults.
**Middle aged (45-64 years old): Can go to work with a higher chance of getting promoted compared to adults.
**Elderly (65 years old or older)
** Vampires have their biological age and birthday set separately. However, the biological age must be less than what their age would be based on their birthday and vampires must be teens or older. Vampires do not age.
**Elves have ages chosen similarly to humans, but they do not age past young adulthood. This also applies to some hybrids (although hybrids cannot be created in the Mii Maker).
*Gender preference: This feature allows players to choose which gender the Mii can fall in love with. Each gender can be either allowed or not allowed. By default, no gender is allowed.
**Romantically exploring: If this option is turned on, a Mii may accept confessions from Miis outside of their gender preference and may be set up with them, but will not get problems wanting to confess to Miis of not preferred genders. By default, this is turned off.
* Species preference: Similarly to gender preference, this limits which species the Mii can date (humans, aliens, vampires, elves). Each species can be either allowed or not allowed, but the Mii's own species must be allowed. The default option is all. Dating hybrids requires having both species activated. This section is still available for Miis whose gender preference is none and romantically exploring genders is turned off, but has no effect on gameplay in that case. A separate romantically exploring option is also available here.
* Relations: This allows players to choose how Miis are related to any of the previously created Miis. Relations are not allowed to contradict each other. (For example, if A and B are set as parent and child, C cannot be the sibling of both; however, C can be the half-sibling of both. If two Miis are set as parent and child, the parent must be older than the child.)
** It is impossible to set Miis as married or having step or in-law relations. As such, the only way to form these relations is by in-game romance. Two Miis who have a Mii set as their child are not acknowledged as having a relationship or being ex-lovers (unless this was already the case prior to setting the relation) but have a slightly increased probability of getting together unless they were already together.
** The player can also add names of relatives without making them into Miis.
*Creator: This has no effect in gameplay, but shows up if the player shares the Mii online.
*Country: This feature allows the player to choose which country the Mii is from. There are 258 countries to choose from.
===Voice===
Voice features are mostly the same as in Tomodachi Life. The only difference is that players can now choose different accents regardless of what country they're in.
===Main interest ===
The main interests are a new feature in the game. A Mii must be given a main interest, which affects the types of problems they get more frequently and depending on the interest, may affect how well they get along with other Miis. Miis generally get along better with other Miis with the same main interest. Certain main interests are unavailable in certain modes.
Each main interest also comes with a long-term goal. Once a long-term goal is fulfilled, a Mii gains 5 levels of happiness (meaning the player gives five rewards at once) along with a decorative furniture item which can be put into the Mii's apartment. A main interest can be changed, but only one long-term goal can be fulfilled per Mii. Only the long-term goal of the currently active main interest can be fulfilled. Progress for other main interests is still counted, which means that in some cases, the player can instantly fulfill a main interest by switching it if they have not completed the goal for the previous main (for example, if a Mii with a different main interest with a level of happiness of at least 50 has their main interest switched to island life, they instantly fulfill that main interest and get the reward for completing the island life main interest).
There are certain furniture items or decorations which are more likely to be liked by Miis with certain main interests. Furniture items contain icons indicating which main interests are more likely to like them.
The default main interest set for a Mii is island life, which is the most neutral main interest in terms of how it affects the Mii's actions.

===Likes===
This is a new section with features affecting how Miis like certain things. They are available for all Miis but for younger Miis, they might not make any difference. 
*Favorite season: This feature affects the way Miis act. Miis are more likely to go outdoors during their favorite season and they are also more likely to like seasonal items from their favorite season.
*Clothing style: Miis can be made to like or dislike specific clothing styles, though this still does not guarantee that a Mii likes or dislikes specific clothing. These may overwrite or strengthen preferences set by the main interest. (For example, Miis with the technology main interest are normally more likely to like futuristic clothing but having them dislike futuristic clothing makes them less likely to like such clothes, while making them like futuristic clothing will make them even more likely to like them.)
* Vegetarian: This can be either on or off (off by default). If a Mii is vegetarian, they dislike meat while they are more likely to like plant food such as vegetables and salad. If a Mii is changed from a vegetarian to a non-vegetarian, they might still have meat as their all-time or super all-time favorite food as those aren't changed when a Mii is edited.
===Actions===
These are traits that affect how the Mii acts in-game, but not their personality or likes.
*Sleep: This affects the Mii's sleeping times. This does not affect napping probabilities unless stated otherwise. Miis whose sleeping times overlap with school or work times sleep for less time but have an increased probability of napping. These settings are not available for vampires or toddlers, as toddlers sleep at irregular times while vampires never sleep. In speed mode, as only naps are present, these traits do not affect gameplay at all.
**Normal: The default setting. This Mii sleeps for 8 hours a day at some point between 9 PM and 9 AM (9 hours between 7 PM and 7 AM for young children and children). On school days, teenagers with this trait fall asleep by 11 PM.
**Early bird: This Mii sleeps for 8 hours, and wakes up between 4 AM and 6 AM. As such, Miis with this trait never show up to late night parties.
**Heavy sleeper: This Mii sleeps for 10-12 hours at a time, between 7 PM and 11 AM. They are also less likely to take naps during the day.
** Irregular: This Mii sleeps for 6-12 hours at a time, often with an average gap of more than 24 hours between falling asleep times. Toddlers with this trait sleep for 4-6 hours at a time but more frequently.
**Napper: This Mii sleeps 6 hours a night, between 10 PM and 9 AM, and has an increased probability of napping during the day.
**Night owl: This Mii sleeps for 8 hours, and goes to sleep at some point between 1 AM and 3 AM (9 hours and goes to sleep between 11 PM and 1 AM for young children and children). On school days, children and teens with this trait sleep for less time and have an increased probability of napping after school.
** Nocturnal: This Mii sleeps for 8 hours, and goes to sleep at some point between 6 AM and 12 PM. On school days, children and teens with this trait are often tired at school and go to sleep immediately after school is over.
*Movement (Slow - Quick): On a scale of 1-8, this affects how quickly the Mii walks.
*Facial Expressions: This affects how much the Mii's face changes during the game.
** Flat: The Mii's facial expressions rarely change. Their face only changes away from the default face during brief moments of shock or when they are feeling certain emotions.
** Normal: The Mii's facial expressions change more frequently than those with flat facial expressions but less frequently than those with varied.
**Varied: These Miis will often change their facial expressions even during normal conversations or when they are hanging out at their home.
==Locations==
More information: Tomodachi Islands/Locations
This game features most of the existing locations from Tomodachi Life as well as many new locations. Each location has its own unlock requirements.
There are different islands and other locations in the game, which are:
* Main Island (named by the player): The island where most of the returning places are located.
*Leisure Island: Similarly to Tomodachi Life, it is where the places that are unlocked after someone asks another Mii out are located. However, this island is now exclusive to romantic relationship related places. It is on the right side of Main Island.
*Digital Island: This is a smaller island located in front of Leisure Island. It is for locations that were previously on Leisure Island as well as new locations.
* Collection Island: This island is located on the left side of Main Island. It is where places featured in Tomodachi Collection but not Life are located, along with some new locations.
*Space Station: This location is unlocked after sending an island to space. It is located directly above the main islands. It appears separately from the islands and can be accessed by an arrow pointing up.
*Wuhu Island: This location has been previously featured in various Mii games. It can be accessed by an arrow pointing left.
*Honeymoon islands: Places where Miis go for their honeymoon. Every honeymoon island looks identical. They can be accessed by an arrow pointing down. This location is not available in no romance mode.
==Island Stats==
Island Stats are basic information visible on the save file whenever it is opened. This information is also available in the Office in the Apartment Building along with more detailed stats.
===Island Level===
Island Level replaces Quality of Life from Tomodachi Life. Like Quality of Life, it appears next to a star on the top screen, but is available from the beginning of the game, starting at 0. Island Level is increased by gaining XP, which can be gained by solving problems, unlocking new locations and various other ways. Unlike each Mii's Level of Happiness, for Island Level, the number of XP needed to reach the next level increases every time a new level is reached instead of remaining constant.
=== Achievements===
There are certain save file specific achievents. The menu listing the save files shows how many achievements have been completed out of the maximum. The maximum varies depending on what mode is in use. The full list of achievements for each save file can be found in the Town Hall. Certain achievements can already be seen before they are completed so the player can see what to do in order to complete it. Achievents remain completed even if the conditions for unlocking them are no longer met (so for example, an achievement to have 30 Miis remains completed even if the population goes back down to 29 or lower).
There are 4 different achievement tiers (bronze, silver, gold, platinum) and achievements of a higher tier give more XP upon completion.
Achievement 	Tier 	How to complete 	Becomes visible when 	Notes
Getting started 	Bronze 	Complete the tutorial (unlock Town Hall) 	Already completed when achievements are first seen 	
Population growing 	Bronze 	Have 30 Miis 	Visible by default 	
Building a community	Silver 	Have 100 Miis 	Complete "Population growing" 	
 	Gold 	Have 300 Miis 	Complete "Building a community" 	
Fully populated 	Platinum	Have 600 Miis 	Complete 	
Best friends 	Bronze 	Have two Miis become best friends 	Visible by default 	
Falling in love 	Bronze 	Have a Mii confess their feelings to another Mii	Completed 	Not available in no romance mode
Relationship started	Bronze 	Have two Miis start dating 	A Mii has confessed their feelings or a Mii has tried to set up two Miis	Not available in no romance mode
== Problems==
More information: Tomodachi Islands/Problems
Miis frequently have problems, which can be solved by the player. All problem types from Tomodachi Life return but certain problems might have changed their type. There are also new problem types. When a Mii has a problem, a certain icon appears on their apartment, home or space apartment, depending on where they are at the moment.
Problems that usually require doing an action: 
*Normal (black)
*Friendship (orange)
*Love (pink)
*Anger (red)
*Work/School (purple)
*Home (brown)
Problems that require getting rid of a bar:
*Sadness (blue)
*Shock (lavender, death mode only)
Miscellaneous:
*Playful (green)
*Sleep
==Gifts==
Gifts/good, different from the level up gifts, are items that can be given to Miis, after which an interaction starts. Many gifts return from the prequel, while new ones are added and some are removed due to changes in gameplay.
*Bath set: The Mii is seen singing in a bath tub. Calms down Miis during a normal fight.
* Calculator: Can be used for basic math, shows up to 10 digits. Shows an error message if the player goes beyond the limit or tries to divide by zero. In death mode, these interactions have a chance of making the calculator explode and kill the Mii. Increases the Mii's knowledge skill.
*Cold medicine: Cures a Mii's cold. Useless in any other situations, and has a chance of killing a Mii in death mode if given to a Mii without a cold.
*Disposable camera: The Mii takes a photo, which can be either artistic or in a random location featuring Miis. Afterwards, the player can rate the photo, and a rating affects how much happiness the Mii gets. Unlike the predecessor, the player gets to keep the photo as an item, and can either give it to a Mii as furniture (can be placed on a wall) or sell it to the art gallery.
*Fan
*Frying pan: The Mii uses it to cook a random food in the apartment building kitchen. The food can vary in quality and price, and generally Miis with a higher cooking skill make higher quality or more expensive food. In death mode, there is a chance that a fire can start, and the Mii either dies in the fire or survives and gets shocked. Increases the Mii's cooking skill.
*Hypnotizer: Makes the Mii fall asleep and the player gets to choose a dream to watch. The player does not, however, get the item from the dream.
*Jump rope: The player gets to move the rope while the Mii attempts to jump over it. Increases the Mii's sports skill.
*Kaleidoscope
*Mobile 
*Music box: The Mii listens to the music box, which plays a random music box version of in-game music with the location where it plays. After some time, the music stops and the player has to wind up. Calms down a Mii during a normal fight. Increases the Mii's music skill.
*Painting set: The Mii makes a random painting, which can be given to a Mii as furniture or sold at the art gallery. Miis with a higher creativity skill make better quality paintings, which sell for more money and increase the probability of Miis who have them in their apartment feeling positive emotions. Miis who feel negative emotions make paintings that reflect these emotions. Increases the Mii's painting skill.
*Sewing machine: The Mii uses it to make a random clothing items. Miis with a higher clothing skill generally make more expensive items or ones the player has not unlocked yet. Increases the Mii's fashion skill.
*Slide puzzle: The player gets to solve a slide puzzle, which consists of 8 pieces (and one empty square) that form a picture with a Mii in it. Continues until the puzzle is completed or the player gives up. Increases the Mii's gaming skill.
*Stomach medicine: Cures a Mii's stomach ache. Useless in any other situations and has a chance of killing a Mii in death mode if given to a Mii without a stomach ache.
*Swing: The player gets to push the Mii, who sits on the swing. This can continue as long as the player wants. Calms down a Mii during a normal fight. Increases the Mii's courage skill.
* Travel ticket: The Mii travels to a random location around the world with up to 3 other Miis, and the player three takes photos of them. After this, the player gets to choose one of the photos to keep as an item to either sell or give to a Mii. The player also gets a treasure, which depends on the location. Using a travel ticket increases the Mii's relationship with the Mii(s) who came with them by 1 or 2 levels. Unlike the predecessor, the player gets to choose which Miis come with the Mii from their list of relationships (exes can only come if the relationship is yellow green or higher, co-workers/classmates can only come with yellow or higher, and enemies cannot come at all). If the Mii is sad, they go alone and do not give a treasure, and all sadness is removed.
==Level Up==
Like in the previous Tomodachi games, Miis have levels, which increase as the Mii gains happiness. Every time a Mii levels up, the player gets to choose something for them. When a Mii reaches level 30, the option to give them any clothes or hats that the player has previously bought is unlocked. There is no upper limit to which level a Mii can reach, and the amount of happiness needed for the next level remains constant.
===Gifts===
Level up gifts are items that can only be given to Miis when they level up. Miis can be seen using these items in some locations. Miis can have up to 10 gifts (certain special interests give Miis the ability to have up to 12 gifts, as long as at least 2 of them are from special categories). With a potion, they can have up to 12 (or 14) gifts.
Unlike in the previous game, Miis own cell phones by default, and they aren't counted in the list of gifts. In addition, new gifts have been added, some of which were previously tresures. The mirror, punching bag and treadmill, which were previously level up gifts, have now been made types of furniture and can be bought from the Interiors shop.
Whenever Miis use level up gifts, a specific skill increases based on the gift. Most level up gifts increase one skill, but laptops increase both knowledge and gaming. When Miis use items that increase the collecting skill, when the player visits them the next time, they give an item of a certain collection.

=== Songs===
Songs return from the previous game. All songs from Tomodachi Life return (including Enka), and there are also new songs. Giving a Mii the same song twice allows them to perform an extended version of the song with more lines (the shorter version remains available). Giving a Mii a song as their level up gift also slightly boosts their music skill. The Smash Bros. genre allows the player to add custom lyrics to the Super Smash Bros. Brawl theme.
List of genres:
*Ballad
*Country
*Enka
* Jazz
*Metal
*Musical
*Opera
*Orchestral
*Pop
*Rap
*Rock and Roll
*Smash Bros.
*Spooky
* Techno
===Phrases===
Unlike in the prequel, in this game, the phrases for each emotion can be given as level up gifts. The player can give any phrase without having unlock the ability to give it and change it afterwards without having to level the Mii up. The phrases can now be up to 100 characters long, as opposed to the much shorter limit in the previous game.
*Catchphrase: This is what the Mii sometimes says when in a neutral mood and they can also say it during certain events.
*Happy: This is what the Mii says when they're feeling a positive emotion.
*Sad: This is what a Mii says during a sadness problem or when they're sick.
*Angry: This is what a Mii says when they're in a fight.
*Worried: This is what a Mii says when their problem involves an important decision, such as starting a relationship.
*Playful: This is what a Mii says when they want to play a game.
*Bored: This is what a Mii says when they feel bored.
*Tired: This is what a Mii says when the player wakes them up from their sleep.
*Thankful: This is what a Mii sometimes says after the player solves their problem, especially after an important problem.
*Hungry: This is what a Mii says when they're about to ask for food. This phrase is exclusive to Miis whose main interest is food.
*Shocked: This is a phrase that appears exclusively in death mode. This is what a Mii says if they have gone through a near death scenario (such as surviving a fire, plane crash or natural disaster).
===Previously bought ===
Like in Tomodachi Life, Miis can be given previously bought clothes and hats for free as soon as they reach level 30. Miis with fashion as their main interest unlock this ability at level 20. Miis with the world as their main interest can be given previously bought interiors as well (but not furniture).
===Seeds ===
Miis with outdoors as their main interest can be given seeds when they reach level 20 or a higher level. When given a seed, the Mii leaves the home, and returns with a plant. Having a higher collecting skill increases the probability of getting rarer plants or plants that the player has never received before. The plants that can be found are treasures, but can also be used as furniture when placed in pots.
===Potions===
Unlike other gifts, potions cannot be given directly. Instead, the player has the option to give the Mii a potion point, and with enough potion points, the player can give the Mii a potion. Some potions are more expensive than others, and some are one-time use only with permanent effects, while others have temporary effects. Some can only be used in specific situations.
*Age Advancing Potion: Skips the Mii's current age group and makes them start the next. Only available in speed mode and not available for vampires in any age group. Can be used until the Mii reaches their maximum age group.
* Age Restoring Potion: Makes the Mii the age they should be based on their date of birth. Might lead to a Mii having to break up or quit their job. Only available in speed mode and not available for vampires or Miis who are already the correct age. Can be used multiple times.
*Anti-Age Potion: Moves the Mii's age back to the beginning of their current age group. Only available in speed mode and not available for vampires or young adult elves, part-elves or part-vampires. Can be used multiple times.
*Break Up Potion: Automatically makes the Mii break up with their current sweetheart/spouse. Not available in no romance mode. Can be used whenever the Mii is in a relationship, and does not prevent future relationships.
*Business Potion: Increases the Mii's business skill. Can be used as long as the Mii has not maxed their business skill.
*Collecting Potion: Increases the Mii's collecting skill. Can be used as long as the Mii has not maxed their collecting skill.
*Cooking Potion: Increases the Mii's cooking skill. Can be used as long as the Mii has not maxed their cooking skill.
*Courage Potion: Increases the Mii's courage skill. Can be used as long as the Mii has not maxed their courage skill.
*Creativity Potion: Increases the Mii's creativity skill. Can be used as long as the Mii has not maxed their creativity skill.
*Dream Potion: The Mii is guaranteed to get a dream whenever they sleep (only once per sleep, though). One use only.
*Family Potion: Increases the relationship the Mii has with family members, and makes them more likely to meet relatives such as cousins, aunts, uncles, nephews, nieces, grandparents and grandchildren. The Mii is also more likely to want to have or adopt a child. One use only.
* Fashion Design Potion: Increases the Mii's fashion design skill. Can be used as long as the Mii has not maxed their fashion design skill.
*Flirty Potion: Increases love problems. This means they are more likely to ask someone out if single, more likely to try to get married when dating, and more likely to want children when married. Not available in no romance mode. One use only.
*Gaming Potion: Increases the Mii's gaming skill. Can be used as long as the Mii has not maxed their gaming skill.
*Home Potion: Increases the probability of a Mii wanting to get their own house in Mii Homes, and if in a relationship, increases the probability of wanting to get married. If they already have a home, it increases the probability of them spending time there. They are also more likely to want furniture. One use only.
*Knowledge Potion: Increases the Mii's knowledge skill. Can be used as long as the Mii has not maxed their knowledge skill.
*Level Up Gift Potion: Increases the number of possible level up gifts by 2 (so from 10 to 12 or 12 to 14 depending on the main interest). One use only.
*Money Potion: Increases the amount of money this Mii gives for actions. Can be used up to 3 times, each use increasing the amount more.
* Music Potion: Increases the Mii's music skill. Can be used as long as the Mii has not maxed their music skill.
*Potion Reversal Potion: Removes the effects of all one-time potions (except Vampire Potion and Level Up Gift Potion), and allows the reactivation of any of them (including the Potion Reversal Potion itself) for free at any time. One use only.
* Random Skill Potion: Increases a random skill that isn't maxed. Can be used as long as the Mii has skills that have not been maxed yet.
*Social Potion: Increases the probability of the Mii hanging out with other Miis, and the amount of friendship problems. Also increases the probability of a Mii wanting to become best friends with another Mii. One use only.
*Sports Potion: Increases the Mii's sports skill. Can be used as long as the Mii has not maxed their sports skill.
*Survival Potion: Makes the Mii immune to all types of death except natural disasters and end of the world. Natural disaster survival probability is also increased to 75%. Only available in death mode. One use only.
*Vampire Potion: Can be used to turn a human Mii into a vampire. The effect of this potion cannot be reversed. Cannot be used on the lookalike, a human with a child living with them (unless the other parent is a vampire), a non-human Mii (including part-human hybrids) or Miis below the age of 13.
==Mii Stats==
When visiting a Mii's apartment or checking their profile on the Mii list, the player can see certain stats. Some stats can only be seen in one of the two locations.
One of the Mii's stats is a list relationships, more details of which can be seen in the "Relationships" section on this page. In addition to the relationship list, family relations can be seen in more detail in the family tree section in the Town Hall.
===Skills===
Skills is a section that is not present in the previous games. Skills start at level 1, and can be improved up to level 10. Skills can be improved by various ways, and having a certain main interest or personality helps improving a specific skill. Each skill can also be increased by a potion. Skills are required to get certain jobs or to improve work performance.
*Business: The business skill is boosted by having money as the main interest. The skill can be improved by having a job, especially when the player buys an item while the Mii is selling it or does successful actions while the Mii is present at a job. Miis generally need a certain level in the business skill to get promotions, as well as higher-paying jobs. Miis with a higher business skill are also less likely to get fired.
*Collecting: The collecting skill is boosted by having outdoors as the main interest. The skill can be improved by giving Miis collection type level up gifts that encourage them to go look for stuff. Miis with a higher collecting skill generally give rarer or more expensive treasures after Mii games, and rarer gifts/goods after random interactions. They are also more likely to find missing treasures of a near complete collection.
*Cooking: The cooking skill is boosted by having food as the main interest. This skill can be improved by giving the Mii a frying pan. Having a higher cooking skill improves the quality of the food Miis make with a frying pan, and increases the probability of it being more expensive.
*Courage: The courage skill is boosted by having an energetic personality (50% boost from confident and outgoing, 25% boost from realistic). Courage can be increased by giving Miis the swing, and by having them successfully complete actions that had them use the worried phrase. Miis with a higher courage are more likely to get problems where they ask to do an action that has consequences, and to try again after a failed confession.
*Creativity: The creativity skill is boosted by having a calm personality (50% boost from easygoing and reserved, 25% boost from realistic). The creativity skill can be improved by using the painting set or disposable camera. A higher creativity skill increases the probability of higher quality paintings and photos the save file has never had before.
*Empathy: The empathy skill is boosted by having a loyal personality (50% boost from outgoing and easygoing, 25% boost from realistic). Every time the player pats the Mii (giving them happiness), the Mii's empathy skill is slightly improved. It is also improved whenever a Mii is successful in a relationship related problem. Miis with a high empathy skill are more likely to make friends, have a high relationship with other Miis, and make up after a fight.
*Fashion: The fashion skill is boosted by having fashion as the main interest. This skill can be improved by giving the Mii a sewing machine. Having a higher fashion skill improves the probability of Miis making more expensive clothes.
*Gaming: The gaming skill is boosted by having technology as the main interest. This skill can be improved by beating Miis at games, or by having them use their level up gift gaming consoles. Miis with a higher gaming skill are more likely to do well in Arcade games, and are also more likely to show up as the random characters.
*Knowledge: The knowledge is boosted by having an independent personality (50% boost from confident and reserved, 25% boost from realistic). This skill can be improved by Miis using study kits or books, as well as going to school (for kids and teenagers). Having a higher knowledge skill improves the probability of doing something (such as getting a house) successfully.
*Music: The music skill is boosted by having music as the main interest. The skill is improved every time the Mii performs a song in the concert hall, and also by musical instrument level up gifts. Having Miis with a higher music skill perform increases the amount of cheering heard.
*Sports: The sports skill is boosted by having sports as the main interest. This skill is improved whenever Miis are using their sports equipment level up gifts, or with the jump rope gift/good. Having a higher sports skill increases the probability of the Mii winning in sports events.
==Relationships==
Like in the previous games, Miis have relationships with other Miis. Relationship types include friends, family, sweethearts and best friends.
===Relationship Statuses ===
These show how well the two Miis get along. Note that the relationship might be different from the other Mii's perspective. Friends with a higher relationship status are more likely to become best friends and make up after a fight. Dark green is the best relationship status while blue is the worst.
As weddings are not held immediately after the proposal, there is now a new relationship type, which is engaged, although it is mostly the same as sweethearts, the only difference being the name of the dark green relationship status.
With the addition of school and work, a new relationship type has been added, which is classmates (for children and teens) and co-workers (for young adults and grown-ups). Classmates is for any Miis who are in the same school year as the Mii, while co-workers is for Miis who work at the same job. This category is only used for Miis who are not already in another category (so, only for Miis who would otherwise not be listed).
In death mode, there is an extra relationship, which is enemies. Miis become enemies after a fight if the resolving is unsuccessful, and if enemies have a good enough relationship, they can become friends again. Miis can also become enemies if one Mii finds out that another Mii killed their best friend, sweetheart, spouse or family member.

*Recently befriended: Fun
*Recently became best friends: Trustworthy

* Enemies to friends: Not much fun...
===Dating===
Like in the previous installments, Miis are able to form relationships. However, the rules of which Miis can form a couple have been changed with the introduction of the gender preference feature and more detailed age groups. Miis are more likely to have feelings for Miis who are closer to their age. Dating is absent in no romance mode.
Here are the rules explaining which Miis can date:
* Miis of the Toddler and Young child age groups are unable to date.
*Miis of the Child age group are able to date other Miis in the same school year. Relationships involving children have a higher chance of breaking up but breakups and rejections cause less sadness.
*Miis of the Teenager age group are able to date other Miis of the same age group (up to 5 years younger) and Miis who are up to 5 years older than them (comparing full dates of birth). 13-year-olds can date 12-year-olds in the same school year.
*Miis of the Young adult age group are able to date older Miis and other Miis of the same age group. Miis below the age of 25 are able to date teenagers if their age difference is 5 years or less.
*Miis of the Adult, Middle aged and Elderly age groups can date Miis who are 20 years old or older.
*Elves, aliens and any hybrids have the same dating requirements as humans based on their chronological age.
** Young adult elves, and elf-hybrids who do not age past young adulthood can, however, date teenage vampires, as long as the vampire is at least 15 years old.
*Vampires can date other vampires with the same requirements based on physical age. Couples where both Miis are vampires cannot break up unless one of them is given the break up potion or at least one of them has the noncommittal trait.
*Vampires can date Miis of other species based on their physical age. However, if the vampire is a teen and is dating another species, once the non-vampire is more than five years older than the vampire, they will be forced to break up, making both Miis sad. However, if they are 15 or older and dating an elf or a hybrid that does not age past young adulthood, they will stay together.
*Vampire hybrids can start dating as soon as they become teens, but can only date Miis who are physically 15 or older, as well as any teen vampire hybrids who are physically less than 5 years younger than them.
*If two Miis have been set as related closely enough to count as family, they are unable to date. However, adoptive siblings and step-siblings are able to date but are much less likely to have confessions compared to friends.
*Gender and species preferences affect which Miis can become couples. Miis with none as the gender preference or Miis whose age, gender, species and preferences don't match with anyone else's are unable to date.
====Confession====
When a Mii has feelings for another Mii, they can confess their feelings for another Mii.
====Marriage ====
If a couple has a high relationship status, one of the two might want to propose to the other Mii. If this happens, the player can choose a location for the proposal.
*Fireworks Show (Park)
*Train Station
*Ferris Wheel (Amusement Park)
*Fancy Restaurant
Unlike the prequel, where the wedding is held immediately after a successful proposal, the player can now schedule the wedding for any future time and date. The wedding will be held as soon as the game's clock reaches the time or the next time the player opens the game afterwards. During this time period, their relationship status will be listed as engaged. A wedding can be cancelled if the Miis break up, one of the Miis is deleted or dies (in death mode), or if the player messes with the island date or the Miis' ages so the wedding date is no longer in the future or at least one of the Miis is no longer above the age of 20 during the wedding.
Following the wedding, the two Miis go on a honeymoon using a travel ticket. After that, a new house is built for them, and a wedding cake will be added to the food item list. 
Only couples where both Miis are young adults or older can get married. It is possible for teenagers to propose (as long as neither Mii in the couple is a vampire) but if the proposal is successful, they must wait until both are 20 to actually hold the wedding.
==== Break Up====
Sometimes, relationships can end when a couple breaks up or gets divorced. Following a break up or divorce, both Miis get sad (unless specified otherwise), and after a divorce, their house gets destroyed or one of the Miis moves out. There are a few ways how this can happen.
*If a couple gets into a fight, if they fail to resolve the fight, the couple breaks up.
*If a couple has a low relationship status, there is a chance one of the Miis gets a problem where they ask if they should break up with the other Mii. The player can choose to either have them break up (where they break up no matter what) or try to work things out, where there is a chance they remain together or the other Mii refuses to stay in a relationship, which also leads to them breaking up.
* A couple between a vampire and a human/alien can lead to an automatic break up if the vampire is a teen and the human/alien becomes more than five years older than them.
* In speed mode, if Miis are given age-altering potions, they might no longer be in the correct age range to date, leading to an automatic break up similar to the one with teen vampire and human/alien couples.
*Sometimes, a Mii can confess to another Mii who is already dating someone else. There is a small chance the Mii that receives the confession accepts it (can only happen if the Mii's relationship with their current special someone is low), causing them to break up with their previous sweetheart or spouse. In this case, only the Mii that didn't start a new relationship gains sadness.
*With enough potion points given as level up gifts, the player can purchase a break up potion, which automatically makes a Mii break up or get divorced. When this option is used, only the other Mii gains sadness.
If a Mii has a high enough relationship status with their ex, they can hang out like normal friends. They also have a chance of becoming best friends, and if the best friendship ends, they go back to being ex-lovers. Broken up Miis also have a chance of getting back together.
In death mode, a relationship can also end if one of the two Miis dating dies. In speed mode, a similar thing happens if the older Mii turns 100 and is banished from the island, but with no sadness involved. A relationship can also end if one of the two Miis is deleted. In these cases, if the couple was married before, the remaining Mii keeps the house (regardless of whether they previously owned it).
===Families===
Like in Tomodachi Life, Miis can have families. Families are much more detailed in this game than in Tomodachi Life, and there is an option to view family trees in the Town Hall. Family relations can be formed by multiple ways.
====Setting Miis as related====
When a Mii (other than the first Mii) is created, the player is given the option to choose how a Mii is related to any of the pre-existing Miis. If a Mii is set related to a Mii with pre-determined relations, the new Mii will automatically also be related to Miis related to that Mii accordingly. So, for example, if a new Mii C is created and set as the sibling of pre-existing Mii B, and Mii A is Mii B's parent, Mii A will also become Mii C's parent. There is also the option to set relations as adoptive. It is also possible to add names to family trees without having to create Miis. This option is unavailable for Miis born on the island, who are instead given relations based on those of their parents and their relation to their parents cannot be changed.
==== Children====
Miis living in Mii Houses can have children. Any couple or single parent can adopt children, but only couples with a male Mii and a female Mii can have biological children. Couples where the female Mii is a vampire or in the middle aged or elderly age group cannot have children either. A single parent vampire must own an apartment before they can adopt a child.
Normally, only one child is born or adopted, but sometimes, the children can be twins or triplets. Twins and triplets are always fraternal by default, but the player can edit them to be identical. Adopted twins and triplets are also counted as each other's biological siblings.
The first thing about a baby that is determined is their gender. The player can either request a specific gender or have it chosen at random. The latter option results is a 50% chance of male and 50% female. A biological child will take an appearance that takes traits from both parents, while an adopted child has a completely random appearance. This appearance can be changed by the player directly after the child is born/adopted. The birthday of a biological child is always on the day of birth, while the birthday of an adopted child is a few days before the adoption.
Babies born to parents of different species become hybrids of the two species and combine traits of the two species. They can also be edited in the Mii Maker. All hybrids get an apartment after reaching the toddler stage, and so do aliens born on the island. If a hybrid has a child, the species passed down will be chosen at random for other species, while for human-elf or alien-elf hybrids, it is determined whether they chose to age past young adulthood. However, children of two hybrids of the same type will always be the same hybrid type (so, for example, the child of two human-alien hybrids has a 100% chance of also being a human-alien hybrid instead of a 50% chance of being a hybrid, 25% human and 25% alien). Female vampire hybrids cannot pass down the vampire species. Adopted children are always humans.
Table giving short descriptions of the hybrids (note that having a vampire mother is impossible).
Father >Mother v	Human 	Elf 	Alien 	Vampire
Human 	Normal human 	Same appearance options as elves, but cannot have non-human skin colors. Like elves, they are more likely to like fancy items. They age normally in childhood, and go to school, but once they turn 20, the player gets to choose whether they continue aging.	Same appearance options as aliens, but have all human hair options and more limited skin color options, and can only have up to 6 eyes. Like aliens, they are more likely to like technology. They age normally and go to school. 	Same appearance options as vampires, but skin color options are limited to slightly paler versions of human skin colors (not as much as those of vampires). Like vampires, they rarely go outside. They only sleep roughly 3 hours a night as opposed to 8 like humans. In childhood, they age three times as quickly as humans, reaching the young child stage at age 1, child at 2 years and 4 months, teen at 4 years and 4 months, and young adult at 6 years and 8 months, after which they stop aging. As a result, they do not go to school.
Elf 	Same as human mother/elf father 	Normal elf 	Have the same appearance options as aliens, but with additional hairstyles and ears available, and can only have up to 6 eyes. Age the same way as human/elf hybrids. They have a slightly increased probability of liking technology and fancy items, and are more likely to dislike cheap items. Aging works like human-elf hybrids.	Same appearance options as elves, but each skin color option is slightly paler, the completely white eye option is replaced with an eye with a slightly visible iris, and all vampire eye and mouth options are available. They are more likely to like fancy items and also less likely to go outside. Their aging works like that of human-vampire hybrids.
Alien 	Same as human mother/alien father	Same as elf mother/alien father 	Normal alien but starts out with an apartment instead of a space apartment if chosen to stay on the island 	Same appearance options as aliens, but some of the darker skin colors are unavailable and all eye and mouth options of vampires are available, and the same hair options as human-alien hybrids, and can only have up to 6 eyes. They are less likely to go outside, but do not have a reduced chance of visiting space locations if they have a space apartment. Aging works like that of human-vampire hybrids.
After a baby's gender and appearance are determined, the parents suggest a name for it. The player can either accept the name, ask the parents to choose another name or name the child themselves. The English version of the game uses the following list of names.

====Relations====
There are many possible ways Miis can be related, and if the relation is distant enough, the two are not counted as related in-game (but can still appear in the same family tree).
*Direct family: Direct family members are the only ones included in family relations by default. Direct family members are also more likely to visit each other during certain holidays than more distant family members.
**Parents: Further divided into biological and adoptive parents. Biological parents, if available, consist of one mother and one father (unless the parent Miis' genders have been changed afterwards) while adoptive parents can be any gender.
**Siblings: Siblings and half-siblings share at least one parent with the Mii. Divided into biological siblings and adoptive siblings.
** Children: Any children the Mii has had or adopted.
*Other family: Any (biological) relatives still considered family members without being listed by default (any sibling based relations are counted as the same regardless of whether it involves a full sibling or half-sibling):
** Any direct ancestors or direct descendants more distant than parents or children (such as grandparents and grandchildren)
**Any siblings of direct ancestors or direct descendants of siblings (such as aunts, uncles, nieces and nephews)
**First cousins, as well as first cousins once removed (cousins of parents or children of cousins)
* Step-family: This only includes step-parents, step-siblings and step-children. These occur when the Mii's parent marries a new Mii or the Mii marries someone who already has children. They might be other relatives as well (for example, a Mii's maternal step-siblings could be their paternal cousins).
*Other relations, as well as in-laws, are not recognized by the game, although they can still appear in the same family tree.
===Best Friends===
Miis can be best friends with another Mii. Best friendships now have a more important role in the game. Miis becoming best friends is now a friendship problem, and cannot happen off-screen. When a Mii wants to become best friends with another Mii, they ask the player what they think about it. The player can either accept or reject the decision. If the player accepts it, the Mii will go to the other Mii's apartment and either succeed or fail at becoming their best friend. The Mii will not gain sadness if it doesn't work, but their friendship with the Mii will become slightly lower.
In no romance mode, best friends have a more notable role than in other modes, as they replace couples as the unlocking requirements for certain locations.
==Holidays==
Like in Tomodachi Life, shops and sometimes other locations are decorated during special days and special items are available. All of these days (except birthday and the ones listed in "other days") are days Miis can be chosen to celebrate when creating or editing them.
Some special days have foods that are only sold on those days. They can be bought on any day afterwards if the player has previously bought them, which is why they are not considered rare foods. April Fools cake and birthday cake, however, are rare foods and are not available in the Food Mart on their respective days.
Any special interactions (including specifically dressed shop keepers) only appear if at least one Mii celebrates the day. Food items of those days can still be bought on those days regardless of whether a Mii celebrates it.
Holidays are not present in speed mode due to the shorter length of days. Birthdays are present but are celebrated less frequently.
Holidays may cause anachronism, as when the time is set to the past, the Miis can celebrate certain holidays before they even existed, or before their current timing was set.
===Birthday===
Unlike other days listed here, birthdays are not counted as holidays on the Mii's profile, and as such, a Mii cannot be super enthusiastic about it. This also means the birthday interactions are not optional.
====All Miis====
Miis gain twice as much happiness on their birthday but Miis born on a leap day gain 8 times as much happiness on their birthday (losing happiness and gaining sadness are not multiplied). However, this effect can only happen once a year, so if the Mii has already gained extra happiness of their birthday, they can't gain extra happiness again in the same year. Miis' birthdays no longer show up on the news but instead Miis can be seen celebrating their birthdays in the Café. Binary Miis are unable to celebrate birthdays due to the fact that their birthday is not a real date.
If the game is opened on a day when a Mii reaches a new age group, the player gets a call from the Mii and is directed to their home. The Mii mentions reaching a new age group and a three-part cutscene is shown similar to the age-o-matic and kid-o-matic cutscenes in the prequel, and the parts of the cutscene depend on the Mii's age group.
Birthdays are present in speed mode, but only when a Mii reaches a new age group. Whenever this happens, time freezes and the player is directed to the Mii's home. The age group cutscene is still shown, but can be skipped.
====Lookalike====
On the player's lookalike Mii's birthday, Miis will hold a party for the player. The lookalike shows up along with 9 other Miis. They congratulate the player. Each of the 9 guests gives a random (non-special) item to the player, after which the lookalike gives a special birthday cake. This party can only be held once a year, even if the lookalike's birthday is changed. If the lookalike was born on a leap day, each of the guests gives 4 random items and the player receives 4 birthday cakes instead of one (in this case, no birthday parties can be held for the player in the next 3 years). The player's lookalike also does everything a normal Mii does for their birthday.
The rooftop is also decorated during the Late Night Party on the player's birthday.
In speed mode, this happens whenever the lookalike or lookalike's heir ages up, the player gets a birthday cake, but the scene of ten Miis congratulating the player is absent.
===National Day===
On the Mii's country's national day (or May 1), the Miis acknowledge that it is a special day. Miis who celebrate their national day can also been seen waving a flag of their country or franchise (Redfurt logo for Miis without a selected nationality) in places on that day. If the player's lookalike celebrates national day, all shops are decorated with the player's lookalike's country's flags on that national day (on top of other decorations if it overlaps with another holiday that at least one Mii celebrates) or on May 1.
For countries with multiple national days, only one of them is acknowledged in the game. For example, for Japan, only National Foundation Day (February 11) is celebrated. All national day timings are based on 2020. Changes based on the day of the week or other recurring patterns are taken into account, but historical changes are not. For example, German Miis still celebrate their national day on October 3 even if the year is set as before 1990.
Some national days also add extra decorations to the shops if at least one Mii has that nationality:
* Australia Day (January 26): Balloons with the Australian flag
*St. Patrick's Day (Ireland/March 17): Clovers and shopkeepers wearing green
*4th of July (United States): Hot dogs and hamburgers in the background, shopkeepers wearing Uncle Sam costumes
*Bastille Day (France/July 14): Balloons with the French flag and shopkeepers greet by saying "Bonjour"
A Mii who is super enthusiastic about their national day will talk about their country (or franchise) more frequently. They show up at the sports stadium with a flag more frequently.
===New Year's (December 31 and January 1)===
On New Year's Eve, Miis light up fireworks during the Late Night Party event. If Miis celebrate New Year's, they wish the player a happy new year on New Year's Eve and New Year's Day. They might ask the player what their New Year's resolution is and four options are given, or mention their own.
A Mii who is super enthusiastic about New Year's sometimes says how many days there are left until the end of the year and is more likely to hang out at the Fireworks Show. They are also more likely to mention what year it currently is.
The special foods for this day are o-sechi and ozouni.
===Opposite Day (January 25)===
On Opposite Day, Miis who celebrate the day have certain aspects be the opposite of what they normally are. They have an increased probability of liking items of the opposite color of their favorite color and those fit for the opposite personality. They gain a positive reaction to their least favorite foods and a negative reaction to their favorite foods. Miis also get the skill boosts of their opposite personality (so, for example, Miis with a loyal personality get a knowledge boost instead of an empathy boost). Aliens are less likely to spend time in space locations on this day. Various places are decorated in ways very different to what they would normally be like. For example, the Sports Stadium is full of beds.
Miis who are super enthusiastic about Opposite Day generally like items of both their favorite color and the opposite color. They are also more likely to be close with Miis with traits opposite of those of theirs (so, for example, ambitious Miis prefer slackers). They can occasionally talk about opposites. In space apartments, they can often be seen upside down.
===Chinese New Year (varies; January or February)===
On Chinese New Year, shops are decorated with red lanterns and shopkeepers are wearing a costume depending on the year starting in the Chinese calendar. On this day, Miis can be seen celebrating the day in the Fireworks Show as well as at home. Miis who celebrate the day can be seen having red paper-cuts on their windows. They can also give the player money in red paper envelopes.
Miis who are super enthusiastic about Chinese New Year often bring up the animals in the Chinese calendar and myths behind the day. They also associate traits with themselves based on their time of birth in the Chinese calendar. They are more likely to become happy in the year matching their time of birth.
There is no special food for the day.
===Super Bowl (first Sunday of February)===
On the day of the Super Bowl, there is more activity in the Sports Stadium. In the audience, Miis can be spotted wearing shirts that, when put together, form a short message (each shirt can have up to three letters). Miis can also play American football there, a sport which is not normally played. Shops are also decorated for the day. Sometimes, on the following day, Miis who celebrate the day say that they were disappointed or satisfied with the half-time show.
Miis who are super enthusiastic about Super Bowl are generally more likely to mention American football. If their nationality is something other than American, they say they wish the event was more international. They are more likely to show up to play American football on the day of the Super Bowl.
The special food for this day is chicken wings.
=== Setsubun (February 3)===
On this day, Miis who celebrate Setsubun gather at the fountain to throw soybeans. If they live in a home and have at least one family member who also celebrates Setsubun, they can throw beans out of the door of their home as well along with other family members. Occasionally, a family member wears a demon mask and the other family members throw beans at them.
Miis who are super enthusiastic about Setsubun greatly enjoy spring, even if spring is not set as their favorite season. Also, as a random quote, they might try to shout at demons, trying to get them to go away. They also mention luck a lot.
The special foods for this day are ehoumaki and fukumame.
===Valentine's Day (February 14)===
On Valentine's Day, shops are decorated for this day and shopkeepers can be seen wearing heart accessories. Miis who celebrate Valentine's Day are more likely to confess their feelings for another Mii, get married or ask the player where they and their sweetheart should go on a date. They also wish the player happy Valentine's Day. In no romance mode, Miis who celebrate the day are instead more likely to have friendship (orange) problems on the day, as love related problems are absent.
A Mii who is super enthusiastic about Valentine's Day has generally more love related (pink) problems. If they are at the Fireworks Show with their sweetheart, they are more likely to kiss. In no romance mode, Miis who are super enthusiastic about the day are instead more likely to talk about and hang out friends.
The special foods for this day are kirichoco and tetsukurichoco.
===Pi Day (March 14)===
On Pi Day, Miis who celebrate the day mention the digits of Pi, and might have a problem where they try to impress the player by citing the first 30 digits of Pi (similar to the Mii impression or funny face problem). Kid and teen Miis are more likely to have a math homework problem. Food Mart sells at least one type of pie on Pi Day.
Miis who are super enthusiastic about Pi Day might occasionally mention digits of Pi on other days, or say math equations. They are also more likely to like any type of pie, as well as a higher chance of making pie with a frying pan. They are, however, less likely to like any type of tea.
The special food for this day is pi pie.
===April Fools' Day (April 1)===
If at least one Mii in the game celebrates April Fools' Day, when the game is openened the first time that day, a news flash appears. This news flash informs that all the islanders have moved to Mars, showing a glimpse of Mars Apartments. The news anchor (must be a Mii who celebrates the day) then informs that this was actually April Fools.
On April Fools' Day, if a Mii celebrates said day, a whoopee cushion appears as a level up gift. It can be given to Miis without taking away any gifts even if their level up gifts are full. Doing so results in the Mii sitting on the whoopee cushion and feeling embarrassed. This makes them lose happiness in a way that they level down (instead of gaining sadness) and give the whoopee cushion back. The player then gains a whoopee cushion treasure, which they can sell at the Pawn Shop.
Miis celebrating April Fools' Day also mention what kind of pranks they did and how well they went. Sometimes, Miis have a problem where they want to prank another Mii and the player can choose a type of prank or tell them not to do it. Rooftop problems also happen more frequently on April Fools' Day.
A Mii who is super enthusiastic about April Fools' Day is more likely to be the Mii on the Rooftop (on any day of the year). If they are given a whoopee cushion as a level up gift, they don't level down and instead give back a fake whoopee cushion, which cannot be sold at the Pawn Shop. A Mii who is super enthusiastic about the day also has a chance of making an April Fools cake with a frying pan.
There is no holiday food for this day, as April Fools cake is a rare food.
===Easter (varies; March or April)===
On Easter Sunday, the game is full of Easter Eggs, which, when found, give players items. Easter Eggs can be found in shops and in the apartments or houses of Miis who celebrate Easter. During the week ending with Easter Sunday, Miis (especially families) can be seen painting Easter Eggs or hiding them in places around their home (the egg disappears as soon as it is placed, so it does not affect gameplay).
A Mii who is super enthusiastic about Easter is more likely to like egg based foods. They can also be spotted hiding random objects in their home during any time of the year. They can talk about bunnies and chicken eggs in their random thoughts. 
The special food for Easter is chocolate egg, which can be bought from the Sunday before Easter until Easter Monday.
===Mother's Day and Father's Day (varies)===
The days on which a Mii can celebrate Mother's Day and Father's Day depend on the Mii's nationality. If the Mii's nationality is a Nintendo franchise, other or a country that doesn't celebrate these days, they celebrate these days on the same days as Japan (Mother's Day on the second Sunday of May and Father's Day on the third Sunday of June).
Mother's Day and Father's Day appear separately on the holiday list but Miis' actions on these days are similar. If a Mii who celebrates Mother's Day and/or Father's Day has their respective parent (either biological or adoptive) living on the island, they might have a friendship (orange) problem where they need the player's help to give the perfect gift to their parent. Family Hangouts are more likely to happen on a day if at least one Mii with family celebrates Mother's or Father's Day on that day.
A person who is super enthusiastic about Mother's or Father's Day generally visits their parent(s) more frequently. If they don't have a parent of the day they're enthusiastic about, they sometimes say they miss their parent (or if they're adopted, wonder about their biological parent). When using a frying pan, especially with a higher cooking skill, they have a higher chance of making the super all-time favorite food of their parent.
There is no special food for these days.
===Doughnut Day (first Friday of June)===
On this day, the Food Mart is decorated with doughnuts. Miis who celebrate the day always like doughnuts on that day unless it is an extreme negative food. In the Morning Market, the player has a chance of getting a free doughnut in addition to the food bought.
Miis who are super enthusiastic about Doughnut Day always like doughnuts, the only exception being if Doughnut Day was changed to their super enthusiastic day afterwards and they had doughnuts as one of their two least favorite foods. These Miis also have a higher chance of making doughnuts with a frying pan, but only if the player does not already have doughnuts in their inventory. They also mention doughnuts more often and have them appear in their dreams.
The special food for this day is a chocolate doughnut with sprinkles.
===Tanabata (July 7) ===
On this day, shops are decorated with bamboo. There is also bamboo in the park, and Miis who celebrate the day can be seen carrying small pieces of paper and attaching them to the tree.
On July 8, if the player visited the game the day before and had Miis celebrate Tanabata, the bamboos in the park are shown burning.
Miis who are super enthusiastic about Tanabata are more likely to like star and plant themed items. The can also tell a shortened version of the story of Orihime and Hikoboshi, two separated lovers who can only meet once a year (although this day is not actually July 7, but rather the 7th day of the 7th month of the lunisolar calendar).
There is no special food for this day.
===Halloween (October 31)===
Shops have spookier decorations and shopkeepers wear Halloween outfits if they celebrate the day. On Halloween, Miis who celebrate the day can have a friendship problem where they want to go trick-or-treating at a specific friens's house. If the other friend celebrates Halloween as well, the trick-or-treater gains happiness and gives the player candy, which can be given to any Mii as food. However, if the other Mii does not celebrate Halloween, their relationship gets worse and the Mii loses a bit of happiness.
Miis who are super enthusiastic about Halloween are more likely to try to scare the player. They are also more likely to get along with vampires. Super enthusiastic Miis are also more likely to go trick-or-treating and gain happiness if the player visits them directly after someone went trick-or-treating at their home.
The special food for this day is pumpkin.
===Thanksgiving (fourth Thursday of November) ===
On Thanksgiving, Miis who celebrate that day are more likely to spend time with their family, or generally in their house or in the house of a family member who also celebrates Thanksgiving. The Miis can be seen sitting around a table and eating a turkey. When the player visits a Mii who celebrates the day, they might mention thinks that they are thankful for, and might even have a normal problem where they ask the player what they are thankful for, giving four options.
A Mii who is super enthusiastic about Thanksgiving can mention the things they are thankful for even on days that are not Thanksgiving.
The special food for this day is Thanksgiving turkey.
===Christmas (December 24-26)===
During these days, shops have Christmas decorations and shopkeepers are dressed up as Santa Claus. Houses where the single Mii or both Miis of the married couple celebrate Christmas have a Christmas tree for the entire month of December. The house will also have Christmas decorations on December 24-26. Miis who celebrate Christmas are more likely to ask for specific items, such as food, clothes or gifts/goods. Miis who celebrate Christmas are also more likely to give something in return. Fights are less less likely to happen on these days.
A Mii who is super enthusiastic about Christmas occasionally says that they can't wait until Christmas or wishes that it was Christmas every day. If they live in a house, that house has a Christmas tree and Christmas decorations for the entire December regardless of whether their spouse or children celebrate Christmas.
The special food on Christmas Eve is roast turkey. On December 25 and 26, other Christmas related foods are sold, but these foods can also be sold on other days.
===Other days===
These days are not holidays in the same way, as Miis cannot celebrate them or be super enthusiastic about them. Many of these also only happen in specific years instead of every time that day happens. Some of these require having the date set in the past. End of the world dates are also part of speed mode.
Black Friday happens annually, but is not a holiday that Miis can celebrate. Black Friday is held on the Friday after Thanksgiving, and occurs regardless of whether or not anyone celebrates Thanksgiving. On Black Friday, items are 50% off. However, in order to enter a shop, the player must defeat a random Mii in a fight (works like the Wrestling Mii Game but with only one round). If the player wins, they can enter the shop and buy whatever they want for the rest of the day, but if they lose, they have to wait 30 minutes to try again. Each shop has a separate Mii fight. Markets and the restaurant are unaffected by Black Friday.
On September 23, 1889, there is a news flash announcing the founding of Nintendo. This can happen in any game mode. The Mii announcing this says they predict the company will achieve something great in the distant future and that eventually the blue stick and red box level up gifts will evolve into something greater.
December 21, 2012 is acknowledged as a potential end of the world date. If death mode is not activated, Miis might mention that they were afraid the world was going to end, but the world cannot actually end. In death mode, however, the world can end with a 22% chance, and if it ends, the Miis living in the Space Apartments survive and get shocked. If this has happened, on any further December 21, the Miis might acknowledge the anniversary of this date.
On Tuesday, February 22, 2022, Miis might occasionally mention that it is Twosday. Miis are more likely to hang out in groups of two that day, and the Food Mart sells two items for the price of one.
January 19, 2038 is Year 2038 Problem Day. On this day, Miis with technology as their main interest start to panic, mentioning that the island's clock may not be able to handle any further dates due to systems storing time in 32-bit. However, as it turns out, the island's clock can handle times until the end of the year 9999 and similarly, it can go to times before 1901 or 1970.
The final possible date is December 31, 9999. If the player reaches that date, shortly before midnight (or as soon as the player opens the game after reaching the date), there is a Mii News announcement that the island and Space Station are about to be destroyed by a meteor, and that the Miis have enough time to evacuate, but not to save the locations. At the end of this news broadcast, the player is given a memory book containing information on every Mii from the old island as well as island stats. The player is then given a time portal and sent back to January 1, 1 (the earliest possible date), where they see an empty island with 8 natives. The player then proceeds to rebuild the island. In speed mode (and in normal mode with the use of time travel), it is possible to experience multiple occurrences of this.
===Combinations===
There are certain actions that happen only if the Mii has a certain combination of days they celebrate.
Miis who are super enthusiastic about opposite day can do these actions on these specific days while Miis super enthusiastic about these days can do these actions on opposite day (only if they celebrate both opposite day and the holiday involved):
* New Year's: The Mii can say "Happy old year!" or talk about the great things about the soon ending or previous year. They can also be seen looking at the sky during the day.
*Chinese New Year: The Mii brings up the animal that is the opposite of the current year (so 6 years earlier/later), and is more likely to mention traits associated with the year opposite to their year of birth.
* Super Bowl: If the Mii has a soccer ball, they have an increased probability of using it on that day. Alternatively, if their main interest is sports, they may avoid any type of sports.
*Setsubun: The Mii can say that they absolutely dislike beans, or that spring is their least favorite season. The latter is more likely to happen if spring is set as the Mii's favorite season.
*Valentine's Day: The Mii has a decreased probability of hanging out with their sweetheart/spouse or having love problems compared to other days, although if it is Valentine's Day and the sweetheart/spouse also celebrates Valentine's Day but is not super enthusiastic about Opposite Day, the former does not happen. The Mii can also state that it is the day when people spend more time with their enemies.
*Pi Day: The Mii can talk about Tau (2 times Pi) or shapes that are not circles. They have an increased probability of liking tea and a decreased probability of liking pie compared to other days.
*April Fools' Day: The Mii acts more serious than usual, not having any normal joke problems (such as funny faces) and befriending Miis more easily if they talk about something serious and less easily if something funny is chosen. However, if it is April Fools' Day, the Mii can still prank other Miis.
* Easter: The Mii can be seen placing fully grown chickens in locations that are clearly visible, although they disappear as soon as the player switches to another view and back. They can also be seen painting already painted eggs white.
*Mother's Day/Father's Day: The Mii spends more time with or talks about the parent of the gender opposite of the day's parent, a non-binary adoptive parent or their children. The first option is the most likely to happen if possible.
*Doughnut Day: The Mii has an increased probability of liking muffins, and have an increased probability of making one with a frying pan. They can also mention muffins.
*Tanabata: The Mii has a decreased probability of liking star and bamboo based items, and can mention not liking bamboo.
*Halloween: The Mii has an increased probability of liking or wanting healthy food and a decreased probability of liking candy or pumpkin-based foods. They avoid hanging out with vampires or Miis dressed up in spooky outfits. They can mention random things and follow it by saying it was the least spooky thing they could think of.
*Thanksgiving: The Mii has an increased probability of having random thoughts where they complain about things. They are also less likely to have a hunger problem, and less likely to casually hang out with family members.
*Christmas: The Mii is less likely to ask for items. They are less likely to spend time inside, and are especially more likely to be in the park, looking at trees that are not Christmas trees. In their random thoughts, they can state that they like the types of trees that have no leaves in the winter or that they think presents are a waste of paper and money. They are also more likely to like summer clothes.
Miis who are super enthusiastic about Valentine's Day and also celebrate Christmas can be seen placing mistletoes on Christmas Eve and Day.
