Instruction: Without quoting directly from the text give me a short bulleted list of the regions in the Pokemon universe, categorized by the real world places they are supposed to be based on.

Context: Kanto
The Kanto region is the setting of Pokémon Red, Blue, and Yellow and their remakes, Pokémon FireRed, LeafGreen, Let's Go, Pikachu! and Let's Go, Eevee!. Based on and named after the Kantō region of Japan, this setting started the precedent of basing the geography and culture of the game's region on a real world setting. This region is also visited in Pokémon Gold, Silver, Crystal, HeartGold and SoulSilver.

Johto
See also: Pokémon Gold and Silver § Setting
The Johto region is the setting of the second generation of Pokémon games, which includes Pokémon Gold, Silver, Crystal and their remakes, Pokémon HeartGold and SoulSilver. Again based on an area of Japan, this game's geography is based upon the Kansai, Tokai and eastern Shikoku areas of the country. The game setting draws upon the Kansai region's abundance of temples, the architectural design of the Kansai region and its geographical sights, such as Mount Fuji and the Naruto whirlpools.

Hoenn
The Hoenn region is the setting of the third generation of Pokémon games, Pokémon Ruby, Sapphire and Emerald, as well as their remakes Pokémon Omega Ruby and Alpha Sapphire. This time being based on the Japanese island of Kyushu; the real world and game region share an abundance of smaller islands around the main one and a subtropical climate. Like Sinnoh, this region is known to have a large range of various natural environments, such as rainforests and deserts.

Sinnoh
The Sinnoh region is the setting of the fourth generation of Pokémon games, which encompasses the setting of Pokémon Diamond, Pearl and Platinum, as well as their remakes Pokémon Brilliant Diamond and Shining Pearl and Pokémon Legends: Arceus. It is based on the northernmost island of Japan, Hokkaidō. The region was meant to have a "northern" feel, with some routes being entirely covered in snow.

Unova
The Unova region is the setting of the fifth generation of Pokémon games, which encompasses the setting of Pokémon Black and White and their sequels Pokémon Black 2 and White 2. For the first time in the main series, the region was based on a region outside Japan, with Unova taking inspiration from the New York metropolitan area

Kalos
The Kalos region is the setting of the sixth generation of Pokémon games, which is where the games Pokémon X and Y take place. This region is inspired almost entirely by the northern half of Metropolitan France, with landmarks such as the Eiffel Tower and the Palace of Versailles having representations here, along with a French style of music and fashion. According to Junichi Masuda, the name "Kalos" comes from the Greek word κάλλος, 'beauty'. The Kalos Pokemon League is based on the Notre-Dame de Paris due to its castle/cathedral-like exterior.

Alola
The Alola region is the setting of the seventh generation of Pokémon games, Pokémon Sun, Moon, Ultra Sun and Ultra Moon. This region is based on Hawaii, marking the second time a main entry Pokémon game setting has been inspired by a U.S. state. The name itself is a play on aloha, the Hawaiian word for both "hello" and "goodbye".

Galar
The Galar region is the setting of the eighth generation of Pokémon games, which is where the games Pokémon Sword and Shield take place. This region is primarily inspired by Great Britain (mainly England and parts of Scotland), showcasing landmarks inspired by Big Ben and Hadrian's Wall. Two additional areas, The Isle of Armor and The Crown Tundra, are based on the Isle of Man and Scotland respectively. The Galar Region was also introduced in Pokémon Journeys.

Paldea
The Paldea region is the setting of the ninth generation Pokémon games Pokémon Scarlet and Violet. The region seems to be based on the Iberian Peninsula, which encompasses both Spain and Portugal.
