Girls Revolution Project × Okada Museum “Plushie Sleepover” on September 25

Girls Revolution Project, a music-and-story project, will hold the special “Plushie Sleepover” event with the Okada Museum of Art in Hakone, Kanagawa on Friday, September 25, 2026, as the second collaboration between the two sides. Fans will leave their Girls Revolution Project finger puppets at the museum after closing on a moon-viewing night for a one-night stay. Only the project’s finger puppets are eligible, and outfits are required to prevent mix-ups. GARASUMIYA serves as publicity captain and will judge the outfit contest. Participation costs 5,000 yen tax included per puppet, covering the overnight stay, commemorative photos, return shipping, a moon-viewing postcard and an Okada Museum admission ticket for one adult valid until October 25. Capacity is limited to 50 puppets on a first-come basis via TIGET from 20:00 on August 14 to 23:59 on August 31 at https://tiget.net/events/506897. Puppets must be mailed to the museum between September 1 and September 20, and can be picked up on site from September 26 to October 4 or returned by post from October 5. The foot-bath cafe will sell the returning collaboration drink “GARASUMIYA: Coffee-scented Jet-black Sparkle” coffee shake for 700 yen tax included from September 26 to October 4, with an “unknown” GARASUMIYA postcard for each purchase.
