NOUSAKU began manufacturing Buddhist altar fittings in 1916, and has more recently started to add tableware and interior products to their lineup. The company is run by the fourth generation of the Nousaku family and produces according to casting techniques typical for the Takaoka region, which is known for its tin and brass casting since 400 years.

One recent innovation of NOUSAKU is the development of tableware made of pure tin. It is sold under the name of flexible ware as it allows the user to flexibly bend the shape as required – again and again without breaking or weakening the material. Some flexible ware can be used as a tray or as a basket depending on how it is being bend. Sake cups made of pure tin are also said to reduce acidity, enhancing the flowery flavor of sake. Water drunk from NOUSAKU pure tin tumblers will also feel softer on the palate.
