A Taste of Sun Hoseki's "Heisei Kawaii" in Shibuya
Hoppe-chan is a hugely popular original character born from Sun Hoseki.
With its soft, rounded shape, round eyes, and colorful, cute design, Hoppe-chan has been cherished by many fans, especially elementary and middle schoolers during the Heisei era. This pop-up puts the newly rediscovered charm of "Heisei retro" Hoppe-chan on display at a souvenir shop in Shibuya.
For those who once enjoyed Sun Hoseki, the items bring back nostalgia, while for a younger generation they feel fresh and new. The "Heisei-kawaii" merchandise is on offer to both domestic and international visitors passing through Shibuya.
