Koshu Inden is a traditional craft originating from Kofu City in Yamanashi Prefecture, with a history spanning approximately 400 years. The term “Inden” means “pattern” and “transmit.” Originally, it was used as decorative items for samurai in Koshu during battles. Techniques brought from India were uniquely developed in the Kai Province (now Yamanashi Prefecture), which eventually became known as today’s Koshu Inden.
