Kouka cardboard box

This is a cardboard box using the two colors of the emblem of the city of Koka, Shiga Prefecture.

Because Koka is the home of the Koka Ninjas, the cardboard boxes can be viewed from a certain direction to reveal the city emblem, and the box can be opened to reveal a secret message about Koka City, or a coded message in ninja characters, for users to enjoy. The cardboard boxes are also used in the packaging of Koka’s hometown tax returns to spread the word about the city’s specialties.
