Hanagataya - Doraemon - Tokyo Banana

Hanagataya is a souvenir shop near the Shinkansen south transfer gate at Tokyo Station, selling Doraemon Tokyo Banana. The product packs soft sponge cake and banana cream in a box featuring Doraemon artwork. The Doraemon design comes in six versions, and the product is gluten-free, made with rice flour. The character inside the box cannot be chosen, so the design you want is not guaranteed.
