"Chilly!! Unko Summer Festival 2025"

This summer, things are cooling down at Japan’s most unexpected museum. From July 10 to September 8, the Unko Museum will host its limited-time seasonal event, the “Chilly!! Unko Summer Festival 2025”, at its locations in Tokyo, Nagoya, and Fukuoka (Fukuoka starts July 19).

Hosted by Tanoshii Museum Inc., the event invites visitors into a frozen poop-themed wonderland where the mythical “Unko Volcano” lies encased in ice. Guests are encouraged to “melt the ice” with their collective energy in this interactive, playful twist on summer fun.

Special Summer Highlights

The festival offers more than frosty decor. Visitors can enjoy limited-edition merchandise, including:

• Summer Unko Stickers (¥350)
• Keychain Gachapon (¥500)
• Acrylic Keychains (¥1,000)
• Square Keychains (¥900)

Nagoya-exclusive colour variants and additional items will also be released during the festival period. Availability varies by location.

Meet Unko BOY

The museum's beloved graffiti-style mascot, Unko BOY, gets his own merch line this summer. Fans can collect limited-edition stickers and keychains featuring the mischievous poop character, born from street art on the museum’s walls.

Join the SNS Campaign

Visitors who follow the official Unko Museum X or Instagram accounts and show their screen to staff at the Tokyo or Nagoya locations will receive a free “Chilly!! Unko Fan”—while supplies last.

What Is “Unko” and the Unko Museum?

In Japanese, “unko” (うんこ) is a lighthearted, informal word for poop. It's often heard in playful settings, especially among children, and carries a tone more silly than vulgar.

The Unko Museum takes this humorous nuance and runs with it - creating a colourful, interactive space where visitors can explore the theme of poop in unexpected and entertaining ways. Rather than provoking with shock, the museum uses laughter and creativity to reframe what’s usually a taboo subject, coining its unique style of experience as “Un-tertainment”.

Since opening in 2019, the museum has drawn over 2 million visitors to its permanent and temporary locations across Japan. The Unko Museum’s main venues continue to introduce fresh exhibits and seasonal events, offering a surprising blend of humour, design, and cultural curiosity - all centred around the most unlikely of topics.
