Japan’s love affair with mascots is the stuff of legend. Think Kumamon’s cuddly bear vibes or Funassyi’s silly pear antics. But now, with Expo 2025 Osaka set to begin on April 13, a new contender has wobbled onto the scene: Myaku-Myaku, a googly-eyed, shape-shifting blob that’s as bewildering as it is unforgettable.

Equal parts adorable and unnerving, this official mascot has taken over Osaka’s artificial island of Yumeshima, leaving visitors and social media buzzing with one big question: who — or what — is this creature? A Cosmic Birth From a Design Competition
Myaku-Myaku’s origins trace back to a nationwide design competition launched by the Expo 2025 organizers, which drew a staggering 1,898 submissions. The winner, unveiled in March 2022, was the brainchild of illustrator Kohei Yamashita, a creative mind known for his work under the moniker “mountain mountain.” Yamashita’s design stood out amid a sea of entries, blending Japan’s love for kawaii (cute) culture with a dash of cosmic oddity.

The mascot’s name, Myaku-Myaku, is a playful nod to the Japanese term myaku-myaku, meaning “continuous” or “ceaseless.” It’s a fitting choice for an event themed “Designing Future Society for Our Lives,” which aims to connect past wisdom with future innovation. But don’t let the linguistics fool you into expecting something conventional. Myaku-Myaku is anything but.

A Shape-Shifting Symbol of Life
Picture this: a fluid blue body representing water, topped with a ring of red cells forming a “head,” complete with multiple spinning eyes and a mischievous grin. Myaku-Myaku’s amorphous form can twist, stretch and split apart, embodying adaptability and the “brilliance of life,” according to its creators. It’s said to be born from the fusion of cells and water; a 3.5-billion-year-old entity that’s somehow both ancient and futuristic.

The design has sparked endless chatter since its debut. Some call it a cosmic horror. Others see a quirky charm that’s pure Osaka. It’s unapologetic and a little weird. Love it or loathe it, Myaku-Myaku’s polarizing look has made it a star even before this year’s Expo begins. It’s popping up everywhere, from plush toys to a transformable figure unveiled by Macross legend Shoji Kawamori at Anime Japan 2025.

Cultural Icon: Myaku-Myaku
Myaku-Myaku is everywhere. It’s plastered across Japan Airlines’ “Myaku-Myaku Jet,” strutting its stuff in an NHK anime series (Ha-i! Myaku Myaku Desu), and even inspiring artisanal collabs, like kogei (traditional crafts) renditions made from porcelain, washi paper and tin. Also, Japanese sports brand Mizuno’s Enerzy sneakers got a Myaku-Myaku makeover, complete with red bubble soles and bulging eyes.

The mascot’s role goes beyond cute chaos, though. It’s a symbol of the Expo’s mission: to pulse with energy, connect people and spark ideas. As visitors flock to Yumeshima, the artificial island hosting the six-month event, Myaku-Myaku greets them at every turn — whether it’s posing with dignitaries or delighting kids with its wobbly antics. Even international pavilions have taken note, with the UK and US rolling out their own mascots (Pix and Spark, respectively) to join the party.

As Expo 2025 unfolds through October 13, expect Myaku-Myaku to keep shape-shifting its way into our hearts (and nightmares). Whether you find it endearing or eerie, one thing’s clear: this is no ordinary mascot. It’s a living, breathing — or at least pulsating — piece of the future.

Yomiuri Telecasting Company: Background to the launch
In 1953 , prior to its launch in Tokyo, Nippon Television Network Corporation (hereafter referred to as "NTV") submitted an application for a broadcasting license in Osaka to the Radio Regulatory Commission . However, at the time, there were only two radio waves allocated to the Osaka area, and licenses were given to two stations, NHK Osaka Broadcasting Station and Osaka Television Broadcasting (OTV, now Asahi Television Broadcasting Corporation ), and the license for "NTV Osaka Broadcasting Station" was rejected.

The reason for the rejection was that "Nippon Television represents the Tokyo area, and broadcasting in Osaka would be 'crossing borders.'" [ note 2 ] Matsutaro Shoriki , head of the Yomiuri Shimbun and Nippon Television , applied to the Radio Regulatory Commission to establish regional broadcasting stations in Sapporo , Nagoya , and Fukuoka in addition to Osaka, but this was also rejected for the same reason . [ note 3 ]

At that time, the Yomiuri Shimbun had expanded into Osaka, and was competing fiercely with the Asahi Shimbun , the Mainichi Shimbun , and others in sales. Since Osaka Television Broadcasting was a television station established by the Asahi Shimbun, the Mainichi Shimbun, and the Asahi Broadcasting Corporation and New Japan Broadcasting (now the Mainichi Broadcasting System), Tsutomu Mitsuo , the president of the Osaka Yomiuri Shimbun (now the Yomiuri Shimbun Osaka Headquarters) at the time , was convinced that "in order to increase circulation against the two newspapers, we need to have our own affiliated television station," and the Yomiuri Shimbun also decided to create a television station with investment from the Kansai business community, centered around the Osaka Yomiuri Shimbun. Tsutomu was the representative promoter and gathered promoters from the business community.

The name of the broadcasting station was " Shin -Osaka Television Broadcasting Co., Ltd. " (abbreviated as NOTV = New Osaka Television . It was called " No-Tele "), and the founding general meeting was held in February 1957. The company building was constructed by borrowing most of the grounds of the Tenman Betsuin temple of the Otani-ha Shinshu sect in Iwai-cho , Kita-ku, Osaka (now Higashi-Tenma ) .

In October 1956, they submitted an application for a broadcasting license to the Minister of Posts and Telecommunications. In October 1957, a provisional license was issued to Shin-Osaka Television Broadcasting as a quasi-educational station (Channel 10, JOIX-TV). The company held its founding general meeting on February 12, 1958, and on August 1 of the same year, the company changed its name from "Shin-Osaka Television Broadcasting" to "Yomiuri Telecasting Co., Ltd." (abbreviated as YTV, nicknamed Yomiuri Television). On the 28th of the same month , it opened as the second commercial television station in the Kinki region, completely transferring all of the Nippon Television programs that had been networked with OTV.

The opening of Yomiuri Television resolved the dissatisfaction of sponsors of Nippon Television Network Corporation's programs, which had not been broadcast in the Kinki region due to OTV's cross-network policy. [ Note 4 ] This also contributed greatly to the increase in circulation of the Yomiuri Shimbun in western Japan .

Among the commercial television stations headquartered in Osaka (Osaka-based television stations), it is the only one that does not have capital from a Kansai private railway , and its capital is composed of Yomiuri Shimbun Group and Nomura Securities affiliates . [ Note 5 ]

Shinoby’s visit coincides with Expo 2025’s mission to celebrate creativity, technology, and cultural exchange under the theme “Designing Future Society for Our Lives.” With dozens of international pavilions and cutting-edge showcases, the Expo attracts millions of visitors from around the world, and mascots like Shinoby and the official Expo mascot, Myaku-Myaku, add a touch of whimsy and warmth to the event.

Write a forum conversation where a user says Shinoby kind of liked playing around with Myaku-Myaku's slime form

User1:
Did anyone else catch Shinoby playing around with Myaku-Myaku today at the Expo? I swear Shinoby seemed to really enjoy messing with that gooey, slime form of Myaku-Myaku. It was hilarious seeing the ninja cat try to dodge and poke at all those wobbly eyes! 😂

User2:
Yes! That was so cute. Shinoby’s playful vibe totally matched the weird charm of Myaku-Myaku’s slime form. Like they were having their own little ninja vs. blob showdown. It made my day!

User3:
I love how the mascots get along. Shinoby looks so chill and confident, while Myaku-Myaku is all wobble and weirdness. They balance each other out perfectly. I hope YTV captures more of these interactions for the broadcast.

User4:
Honestly, Shinoby might secretly be trying to learn shape-shifting moves from Myaku-Myaku’s slime! If that ever happens, the Expo just got twice as interesting. Would love to see a collaboration!

User1:
Haha, right? Shinoby bouncing off that goo was pure gold. The energy was so playful, it made the Expo feel more alive. I wonder if this was planned or just a spontaneous moment!

User2:
I’d bet spontaneous. That’s the best kind of mascot magic — unscripted fun. Can’t wait to see what other mischief they get into before October!

User3:
Agreed! More shinobi slime antics, please!
