Kaga Zougan is a Japanese metal inlay craft tradition that began in the Kaga region (present-day Ishikawa Prefecture) in the late 16th century, when the Maedas, who governed the Kaga feudal domain, introduced inlay techniques from Kyoto. Kaga Zougan initially became famous for its use in decorating samurai swords, armor, and horse harnesses with intricate designs. After the Meiji Restoration, the focus shifted to producing decorative objects such as vases. To create Kaga Zougan products, craftsmen carve patterns into metal, ceramic, or wood, then inlay gold, silver, or other materials into the carved areas. Two main types of Kaga Zougean are Hira Zogan (flat inlay) and Ito Zogan (thread inlay), which are often combined to create highly detailed and elaborate patterns.
