Creative Yoko Co., Ltd. (headquartered in Nagano City, Nagano Prefecture; President: Takeyuki Kitahara) is marking the 27th anniversary of its original character Sirotan with the "Sirotan Birthday Fair," launching Friday, July 10, 2026, at Sirotan's directly run stores nationwide and its official online shop.
This Year's Theme: "Sirotan Puka Puka Marine Park"
Since debuting in 1999, Sirotan has brought comfort and warmth to fans of all ages. To celebrate the character's 27th birthday on August 8, this year's Sirotan Birthday Fair is themed "Sirotan Puka Puka Marine Park."
The key visual is set at a seaside "Marine Park" filled with attractions like a giant Ferris wheel and a roller coaster, where Sirotan and friends Rakko Inu, Ramune, and Sheru wander happily between stage shows and mini shops. The soft pastel tones evoke a nostalgic, heartwarming feeling, calling to mind cherished summer memories and old amusement park outings.
The theme continues into a "Ghost House" and "Game Center" inside the Marine Park. Throughout the fair, pop-up stores and greeting events offer visitors not just shopping, but "experiences and memories" to enjoy.
