About Sumiki

The roof of the rest area of Suikoushya is the Irimoya (hip-and-gable) roof. The structural material used for the slopes of the apex where the roofs intersect is called Sumiki. Knowing the angle of Sumiki is very difficult and you need to learn the method of applying a construction drawing to the materials, named “kiku-jutsu”.Check out this free YouTube video for more information.




Let’s enjoy woodworking together!


We, Suikoushya, plan to establish a school building in Ile de France in 2022. 

This is a project that we want to build with Suikoushya graduates and professional woodworkers. Through this real construction project, Takami would like to pass not only Japanese woodworking techniqs and craftsmanship but also the spirit of the Japanese people involved in making things.
