Sanrio’s beloved golden retriever character Pompompurin is teaming up with a traditional castella specialist for a sweet new treat. The “Pompompurin Castella Caramel Pudding Flavor” is now available from August 1, 2026, marking the first-ever character collaboration for the Osaka-based confectionery Ginsou, which is celebrating its 75th anniversary.
A Flavor That Fits Pompompurin Perfectly
Ginsou, a long-established castella shop in Shinsaibashi, Osaka, created this original product to commemorate its milestone anniversary. The caramel pudding flavor was chosen because it evokes the warm, lovable image of Pompompurin—who recently took the top spot in the 2026 Sanrio Character Ranking. The result is a castella with a gentle caramel pudding taste that is not overly bitter, yet rich enough to satisfy.

Two Exclusive Package Designs
The product comes in two limited-edition packages. One design prominently features Pompompurin’s cute image, while the other imagines Pompompurin visiting Ginsou’s main Shinsaibashi store. Both are sure to delight fans.

Even the packaging extras are special. The paper bag and the inner film wrapping the castella feature original designs with Pompompurin and his “Team Purin” friends. Carrying the bag feels like joining the character’s world. Note that the paper bag is available only at select stores, and customers receive one bag for every two products purchased.
