Does the tree also have a back and belly?
Due to the terrain and sunlight, the core of the tree is biased to either side. This biased side is called the SE (back). The opposite is called “hara”. The SE (back) has a narrow rings of a tree, and the HARA (belly) has a wide ring.
Use SE (back) and HARA (belly) appropriately according to the part to be used.
For example, the beams used for the ceiling are used with the “SE” facing up. The wood used for the floor should have “HARA” facing up.
One of the pleasures of woodworking is to take advantage of these movements and the nature of the wood.
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.
