First introduced to Japan during the Nara period and revered as a sacred material for imperial courts and shrines, tin beautifully evolved in the commercial hub of Edo-period Osaka into everyday vessels cherished by the public. Overcoming immense historical challenges—including wartime mobilization and severe material shortages—it was officially designated a National Traditional Craft in 1983. We continue to refine this ancestral wisdom and pride, weaving lifelong masterpieces that harmonize perfectly with modern lifestyles.
