Example of products


Amid recent calls for the use of Japanese wood, we engage in the sale of Japanese logs.
We also procure logs from overseas and supply them to the consumer market after confirming their legality.
These logs are processed into such products as plywood, lumber, and fiberboard, and are further processed into wooden building materials, including floors and doors. Logs are the basic material of all wooden products.


Plywood is a wooden board made with dried veneer.
The material is peeled from logs and then pasted together, with adjacent material having their wood grain rotated relative to the adjacent layers at a 90-degree angle. It is widely used to make backings for roofs, walls, and floors in houses. Its uses also include concrete panel and secondary fabrication for wooden materials.
The first plywood from Japan was produced more than a hundred years ago. Since then, it has been an essential product for living environments.
We have cultivated a relationship of trust with major plywood manufacturers in Japan and overseas over many years, and by leveraging those strong connections, we are determined to establish a stable supply of plywood to the Japanese market.


We sell both imported and domestically produced lumber, as well as glue laminated timber.
Wooden houses still account for more than 50% of houses in Japan. Furthermore, living environments surrounded by wood, which suit the Japanese culture and climate, are very popular. And of course, the most important part of wooden houses is the lumber that is used for the building frames, such as ground sills, posts, and beams. This is together with common lumber (hagarazai), which supports the building frame.

Fiberboard and particle board

A fiberboard is a wooden board that is made through the disaggregation of wood into fiber. Then apply pressure on the fiber to form a board. Depending of the specific gravity, the boards can be classified into high-density fiberboards (hardboard), medium-density fiberboards (MDF), and low-density fiberboards (insulation board). A particle board is a wooden board that is made by crushing wood into chips. The pressure then forms the chip into a board. This kind of board is used in buildings, furniture, and woodwork. Its uses also extend to building materials and components.
We continue to handle particleboards and MDF from leading manufacturers in Japan and overseas.
