KAYU’s lunch box design is inspired by classic Japanese animation. From cartoon characters, scenes to classic dialogues, each lunch box is carefully designed to make children feel as if they have entered their favorite animation world when dining.

For example, the lunch box may be printed with classic characters from "Demon Slayer: Kimetsu no Yaiba" or images of characters from "Spy's Family Sake". These vivid designs not only surprise children the moment they open the lunch box, but also increase their expectations and interest in dining.
