■About the seal industry in Yamanashi Prefecture
Yamanashi Prefecture is the number one producer of seals in Japan, accounting for 50% of all seals in Japan, and 90% of the seals received when graduating from junior high school. Yamanashi Prefecture has a long history of the seal industry.In the Edo period, a huge crystal was excavated in the territory of Kai Province (Yamanashi Prefecture). It is said that an engineer who was engaged in the production of seals traveled all over the country, preaching the importance and usefulness of seals, as well as their necessity in daily life, and pioneered sales channels. The technique of hand carving, which takes a long time to learn, was certified as a traditional craft designated by the Minister of Economy, Trade and Industry in 2000 as “Koshu hand carved seal”.
