Toyooka Craft Co., Ltd. is a wood-working company founded in 1969 in Hamamatsu, that took over the production of organs, drums, and pianos for Nihon Gakki (now, YAMAHA).
Our company constructs metal-free products using the "kumi-ki" method, in which wooden pieces are fitted together with the help of special cutting and polishing techniques.
One of our special techniques, based on meteorological principles our founder studied at university, allows for 0.1mm increments in construction, taking into account the repeated maximum expansion and contraction of wood of 0.5% in hot or humid
The design and sale of the Toyooka Craft Collection started 30 years ago and has come to be loved by authors, scholars, and other people of culture. It can be found in department stores and world-class catalogs.
