Protector Against Humidity

Among the kind of woods, Kiri wood is one of a rare wood in category of moisture absorption. The duct inside the wood can hinders the passage of water, and because the holes in fiber membranes are small, once it got dried, it will be difficult for water to break through inside.

High Level of Airtightness

Kiri wood inflated to moist outside air to prevent moisture from the outside. Conversely, when the air dries moisture will diverge and shrinks. Since kiri wood is sensitive to humidity, it has excellent airtightness, which able to keep the internal humidity constant, resulting in a long time protection for the contents inside the storage box.

Because kiri wood contains tannin, it has a high resistance towards insects. A cabinet that made from Kiri wood is quite a popular choice in Japan because its excellence in humidity control and insect repellent.

Compared to specific gravity of water which is 1, kiri wood's specific gravity is 0.3, which is the lightest among domestic wood. Because the membrane wall of its cells is thin and the air layer is large, it is soft and very convenient to carry.

Raw Material Preferences

We are using the kiri wood from North America.

The kiri wood product that is distributed in Japan mostly comes from Japan, Chinese and North American, but depending on the production area, there are products that use chemicals in order to make them look beautiful.

In Senshuu Tomekawa, considering that it’s a storage for food ingredients, we are using the kiri wood from North America which contains no chemicals.

Because the annual tree ring is fairly beautiful and the material quality is excellent, we have been using it for about 30 years.

For adhesive, we use the woodworking bond made by Konishi Co., Ltd. We use bonds that is accordant with environmental standards.
