Osaka Suzuki (大阪錫器) traces its roots to the tinsmith Ihei I, who brought Kyoto tin techniques to Osaka in the late Edo period. The modern company was established by Yaichirō Imai in 1949, gathering five tinsmiths committed to preserving their declining craft. Today, Osaka Suzuki is led by Tatsumasa Imai — Yaichirō's grandson and a METI-recognised Contemporary Master Craftsman (現代の名工, certified 2012). The company employs five METI-certified Traditional Craftsmen (伝統工芸士) and produces the vast majority of Japan's Osaka Naniwa Suzuki (大阪浪華錫器), which was designated as a METI traditional craft in 1983. Roughly 70% of all tinware made in Japan comes from this tradition.
Each piece is entirely handmade: molten tin is cast in engraved moulds, then turned on a hand-operated lathe to thin the walls — a process that accounts for the core of the craft and demands exceptional steadiness. Surfaces are hammered for texture and polished by hand to a soft, silvery sheen. Tin conducts temperature remarkably fast — roughly 50 times more than porcelain — which means a chilled tumbler will cool your drink almost immediately. Traditionally, tin is also said to mellow the taste of sake and soften water, a quality that has made tinware a staple of Japanese drinking culture for centuries.
At iromizu, Osaka Suzuki's Fuji tumblers and Berg pairs belong to Brew Time and Gift of Sentiment — objects that make cold drinks feel colder, sake taste smoother, and a gift feel genuinely special. The weight, the gleam, the way condensation beads on the surface — these are small pleasures worth noticing. See them below.
