Ginbis has partnered with Kamakura-based Chocolate Bank to release a special collaboration sweet called “BANK Tabekko Aquarium,” available in limited quantities at JR Nagoya Takashimaya from July 31 to August 9, 2026.
This exclusive treat features 18 chocolate-infused biscuits shaped like 47 different sea creatures, enhanced with Colombian milk chocolate sauce and cacao nibs for a rich flavor and crisp texture. The set is priced at ¥2,916 (tax included), fitting typical convenience store snack pricing in Japan.
About the Collaboration

The collaboration brings together Ginbis, known for its beloved animal-shaped biscuits, and Chocolate Bank, a chocolate specialty shop located in a former bank building in Kamakura. Their shared goal is to create delicious moments for families and loved ones to enjoy together. The “BANK Tabekko Aquarium” uses a unique infusion technique allowing chocolate to soak inside the biscuits, preserving their crunch and preventing chocolate from sticking to hands, making it ideal for summer snacking.



The packaging includes the names of sea creatures in both Japanese and English, continuing Ginbis’s tradition of combining fun and education in their products.
