A new limited edition chocolate biscuit snack arrives at convenience stores nationwide starting February 16, 2026. Ginbis Co., Ltd., the maker of popular Japanese snacks, introduces "Tabekko Aquarium Cocoa Biscuit × Chocolate-Coated," combining cocoa-rich biscuits with smooth milk chocolate coating.
Rich Cocoa Flavor Meets Milk Chocolate
This new product differs from the classic Tabekko Aquarium snacks by featuring a rich cocoa taste. The biscuits incorporate black cocoa powder and Venezuelan cacao-based chocolate, delivering an intense chocolate experience. Each piece is coated with milk chocolate that balances the strong cocoa flavor with creamy sweetness.

The moment you open the package, the rich aroma of cacao fills the air. The biscuits maintain a crispy texture that pairs perfectly with the smooth chocolate coating. The use of black cocoa powder reduces overall sweetness while highlighting the milk chocolate's flavor profile, creating a deeper, more sophisticated taste.
This combination makes the snack appealing not only to chocolate enthusiasts but also to adults seeking a refined treat during their day.

About Tabekko Aquarium

Tabekko Aquarium launched in 2007 as part of Ginbis' educational biscuit line. The snacks feature 47 different sea creature shapes and use a special impregnation manufacturing method that infuses chocolate into the biscuit. This technique allows the biscuits to maintain their crispy texture while delivering chocolate flavor, and prevents the chocolate from melting onto fingers even during summer months.
Like the original Tabekko Dobutsu (animal biscuits), each package includes Japanese and English names of the sea creatures on the back, making it a "communication biscuit" that combines delicious snacking with educational value.
The brand operates under the motto "Dreams in Every Snack!" and continues to create beloved products worldwide using traditional baking techniques refined over generations.
