Department of Wood Engineering

Forest resources of Japan which had planted after the world war II, had grown well. Now we are in a full-fledged use period.
Among the domestic wood use in 2014, about 50 percent was used in construction, and 40 percent of which was domestic wood.
The proportion of wooden houses in new housing is around 55%. But in larger buildings (e.g. public buildings), the proportion is very low, and which has become the challenge.

In the global environmental issues, in order to maintain a high carbon absorption ability, it is important to maintain the vigorous state of forests.
On the other hand, it is important to store the absorbed carbons longer term in building structures or infrastructures and prevent to re-emit to the atmosphere.

The Japan has the history of wood utilization which has a close relationship with own culture. But we need a firm scientific meaning not in emotional.

We conduct the researches to provide the safe, relief and enrichment for modern life. And we research to take advantage of more of the wood.
