Japanese patterns are gathering attention for a checkered pattern being used for the Tokyo Olympics emblem. There is a wide variety of Japanese patterns, such as chidori, karakusa, and mameshibori, and they are unique. Patterns have evolved in ancient Japan as something to feel and enjoy the four seasons.

Foreigners are surprised that Japanese people pursue patterns even for manhole covers and brocade carp. We investigate such appeals of Japanese patterns from the perspective of foreigners.
