Wadasuke Seisakusho (WADASUKE)

From classic Japanese coffee shops to first-class hotels: "Wadasuke Seisakusho," the Tsubame banquetware maker loved by professionals

Wadasuke Seisakusho Co., Ltd. (WADASUKE) is a metal Western-tableware maker based in Tsubame City, Niigata, founded in 1923 (Taisho 12). Known by the "SW" brand mark, it makes a wide range of pro-spec tableware and bar tools used in hotels, restaurants and classic Japanese coffee shops.

The business began with brass kiseru (smoking pipes) and shifted to Western tableware over time. Today it manufactures high-quality banquetware in stainless steel and copper; its excellent functionality and refined design have earned strong trust in professional settings across Japan.

The maker behind "that classic copper mug" of the Japanese coffee shop

Among Wadasuke\'s consumer products, the pure copper mugs and tumblers are especially popular. When you order an iced coffee at an old-school Japanese coffee shop and it comes in a "chilled-to-the-bone copper mug" — many of those are in fact Wadasuke products.

The simple, functional form with unnecessary decoration stripped away, and the wide, stable base — a design born of pro use. They\'re also loved as the standard glass for cold cocktails such as the Moscow Mule.
