History
The history of crystal polishing in Yamanashi dates back to the late Edo period, when Yasuke, the head clerk of Tamaya, who came from Kyoto to purchase rough crystal mined at the foot of Mt.
Kinmine, which is the border between present-day Yamanashi and Nagano prefectures, brought it to the shrine of Kanazakura Shrine.
Yamanashi's crystal industry has developed by overcoming many hardships, starting with the company's employees teaching the method.
