The 2025 Osaka-Kansai Expo, officially known as Expo 2025, has captured global attention as a showcase of innovation, culture, and sustainability. Running from April 13 to October 13, 2025, on the artificial island of Yumeshima in Osaka Bay, the event draws millions of visitors from around the world. At its heart is Myaku-Myaku, the expo’s official mascot—a quirky, enigmatic creature born from the fusion of cells and water, symbolizing the “brilliance of life” and the flow of history, culture, and innovation. With its red cell-like body parts that can multiply and blue water-like fluidity, Myaku-Myaku has evolved from an initially controversial design—often compared to something out of a sci-fi horror—to a beloved icon that’s stealing hearts globally.
However, this surge in popularity has a darker side. Recent reports highlight a series of thefts targeting Myaku-Myaku merchandise at the expo’s official stores, where high-demand items are being stolen for resale on online platforms. These incidents underscore the challenges of managing security at massive international events while highlighting the mascot’s cultural and commercial appeal. For international visitors planning a trip to the Osaka Expo 2025, understanding this phenomenon offers insights into Japan’s vibrant pop culture, the expo’s merchandise craze, and tips for safe shopping. In this post, we’ll dive into the details of these thefts, explore Myaku-Myaku’s rise to fame, and discuss broader implications.
Unpacking the Theft Incidents at Osaka Expo Venues
Thefts of Myaku-Myaku goods have become a recurring issue at the expo’s official stores within the venue. Osaka Prefecture Police have arrested multiple groups of young individuals suspected of shoplifting, with motives tied to resale profits. In one notable case in June, six male university students from Tokyo were apprehended on theft charges after stealing over 100 items valued at approximately 500,000 yen (around $3,300 USD). These students, who bonded over a shared passion for railways via social media, allegedly traveled to Kansai by freeloading on trains like the Shinkansen. Their method was methodical: stuffing plush toys, headbands, and other items into handbags, then stashing them in nearby lockers to continue the spree.
Among the stolen goods were limited-edition items, including the highly sought-after “black Myaku-Myaku” plush toys and collaborations with popular brands. The group admitted to targeting these for their high resale value, planning to sell them online. In a separate incident in July, two 16-year-old boys were arrested for stealing bags, with suspicions extending to two more accomplices—all believed to be motivated by profit.
These aren’t isolated events. Earlier in May, a Myaku-Myaku plushie was stolen from the Baltic Pavilion, captured on security cameras showing two individuals, possibly women, placing it into a bag. Remarkably, this theft sparked a wave of goodwill: Visitors donated over 140 plushies and other items to the pavilion, which were later redistributed to children’s facilities and other institutions. Such community responses highlight Japan’s emphasis on harmony and collective responsibility, turning a negative incident into a positive story.
Investigating these thefts poses unique challenges due to the expo’s scale. The Japan International Exposition Association expanded official shops from 8 at the April opening to 19 to handle massive crowds and long lines. With identical product lineups across stores and a vast array of merchandise, pinpointing the exact origin of stolen items requires meticulous review of security footage and other evidence. One investigator noted that this is inherent to large-scale events, but police are committed to thorough probes.
Why Myaku-Myaku Has Become a Global Sensation
Myaku-Myaku’s journey to stardom is fascinating. Unveiled in 2022, the mascot’s name derives from Japanese words meaning “pulsing” or “throbbing,” evoking life’s dynamic energy. Its design, featuring googly eyes and a shape-shifting form, initially drew mixed reactions—some likened it to creatures from anime like Evangelion or even horror films. Yet, as the expo approached, it gained a massive following, especially among international tourists.
Merchandise sales reflect this boom. Plush toys, keychains, stickers, and headbands top the lists for overseas visitors, with items like the black Myaku-Myaku variant often selling out quickly due to purchase limits. Collaborations amplify the appeal: Sanrio characters dressed as Myaku-Myaku, train-themed charms featuring JR West’s Osaka Loop Line and Doctor Yellow, and even pineapple candy branded with the mascot. Convenience stores like FamilyMart in Kansai stock themed socks and snacks, making Myaku-Myaku accessible beyond the expo grounds.
This popularity ties into Japan’s “kawaii” (cute) culture, where mascots like Kumamon or Hello Kitty drive tourism and economy. For non-native readers, Myaku-Myaku represents more than merch—it’s a bridge to themes of sustainability and human connection, aligning with the expo’s slogan, “Designing Future Society for Our Lives.” Visitors from Europe, Asia, and the Americas often share photos and stories online, boosting its viral status.
The Thriving Resale Market Fueling Thefts
The black market for Myaku-Myaku goods thrives on platforms like Mercari, Japan’s leading flea market app. Limited-edition items, touted as “hard-to-get” or “venue-exclusive,” fetch premiums—up to 1.5 times retail, with black plushies going for around 5,000 yen ($33 USD). This resale frenzy mirrors global trends in collectibles, from K-pop merch to Disney pins, but in Japan, it intersects with a culture of meticulous collecting and online trading.
Thieves exploit this, as seen in the university students’ confessions: They zeroed in on high-value limited goods for quick flips. While resale isn’t illegal, stealing to supply it crosses lines, prompting discussions on ethical consumerism.
Police and Expo Organizers’ Response
Osaka police are proactive, conducting security training for store managers on spotting suspicious behavior. Enhanced camera scrutiny and patrols aim to deter future incidents. The expo association emphasizes visitor safety, reminding attendees to secure belongings and report anomalies—advice that’s universally sound for crowded events.
Broader Implications and Tips for Expo Visitors
These thefts remind us of vulnerabilities at global gatherings, yet they don’t overshadow the expo’s spirit. Culturally, Japan values honesty and community, as evidenced by the donations post-Baltic Pavilion theft. For international travelers, opt for official stores or licensed outlets nationwide to avoid fakes. If visiting Osaka Expo 2025, arrive early for merch, use digital payments for security, and immerse in pavilions showcasing tech and culture.
In conclusion, while shoplifting casts a shadow, Myaku-Myaku’s charm endures, symbolizing resilience. Plan your expo adventure wisely—it’s a once-in-a-lifetime blend of fun, innovation, and Japanese hospitality.
