Due to various factors in the world situation, it has become difficult to obtain Western Red Cedar, which is currently our main species of wood, and we have decided to change the species of wood we use to mainly domestic species of wood from August. By using domestic species of wood, we hope to contribute to sustainable manufacturing.
The following three species of wood will be used as the main wood species used in our products.

Smoke-dried cedar from Kurikoma, Miyagi Prefecture

Smoke-dried cedar from Kurikoma is not suitable for outdoor use, but it is highly resistant to insects due to its smoke-drying treatment. It is locally produced in Miyagi Prefecture.

Yakushima Jisugi (Japanese cedar 50 to 100 years old after planting at the foot of Yakushima Island)

Compared to cedar trees in the northern part of Honshu, Yakushima Jisugi grows about 1/3 faster and has a denser grain. It is also known as “Japanese red cedar” because of its high oil content and resistance to decay due to the humid environment in which it grows.

Non-finger-jointed laminated timber of red cedar

Non-finger-jointed laminated timber (red cedar) is a 25mm thick board. It is a sustainable material because it is uniform without deviation and the manufacturing method uses pieces cut from extra parts of the log, so there is no waste. The AA series in particular is an optimal material in terms of both size and characteristics.

If you would like to use conventional Western Red Cedar, we can provide a quote separately.
In conjunction with this change in the species of wood used, we have revised the prices of some of our products. We are trying to minimize price increases by changing the species of wood used, and we appreciate your understanding in this matter.
We look forward to your continued patronage of Ishinomaki Laboratory.
