Kanazawa Gold Leaf — 99% of Japan's Gold Leaf Production

Kanazawa produces 99% of Japan's gold leaf (金箔, kinpaku), a craft perfected over 450 years. Gold leaf production began in the 1590s when Maeda Toshinaga, second lord of Kaga Domain, brought craftsmen from Kyoto to establish local production. Kanazawa's climate — high humidity year-round — provides ideal conditions for beating gold into sheets 1/10,000th of a millimeter thick (thinner than tissue paper), so delicate that breathing on it causes it to flutter away. The gold leaf adorns temples, lacquerware, ceramics, and Buddhist altars throughout Japan.

Visitors can tour workshops to observe master craftsmen beating gold ingots between layers of special washi paper using traditional hammers, transforming a small gold piece into sheets large enough to cover multiple square meters. The process requires 6–8 hours of rhythmic hammering, humidity control, and decades of experience to achieve uniform thinness. Hakuza Kinpaku (箔座) operates a museum and workshop where you can try gold leaf application on lacquerware or chopsticks. The Higashi Chaya and Nagamachi districts contain dozens of shops selling gold leaf products: cosmetics, edible gold (for decorating food), gold leaf-covered crafts, and pure gold leaf sheets for artisans.
