Supreme x Kama-Asa Steamer
Supreme vs. Original

Supreme version

About the original
Kama-Asa Shoten has sold Japanese cooking tools from its Kappabashi, Tokyo storefront since 1908, curating knives, pots, woks, and steamers from artisan workshops across Japan. The Kama-Asa Chinese-Style Seiro is a 24cm bamboo steamer handmade in Japan from Japanese cypress (hinoki), woven bamboo, and stainless steel reinforcement bands; the cypress absorbs excess steam for cleaner cooking, and the woven bamboo lid vents at a measured rate to prevent dumplings, buns, and fish from getting waterlogged. The seiro stacks for multi-tier cooking and is sized to fit a standard 24cm wok or pot. Supreme's FW24 version is the same handmade seiro (9.64 inches diameter) with a Kama-Asa logo burned into the side.
About Kama-Asa
Kama-Asa is a Japanese kitchenware retailer founded in 1908 by Minosuke Kumazawa in the Kappabashi district of Tokyo, the dedicated restaurant-supply quarter that runs between Asakusa and Ueno. The shop opened as Kumazawa Imono Ten selling cast-iron kama pots before shifting toward chefs' knives, and now carries roughly 60 styles and over 1,000 individual Japanese-made knives sourced from blade-making regions including Sakai, Seki, and Echizen, alongside its own Amane line of Western-style gyuto and santoku knives. The fourth-generation owner, Daisuke Kumazawa, has expanded into Paris and Brooklyn storefronts. Supreme collaborated with Kama-Asa on co-branded Japanese kitchen knives.
