Several new topics related to wood protection sector has appeared in Japan, as the awareness of climate change becomes bigger and bigger. The “Basic act for housing (2006)” and the “Long-life housing promotion act (2009)” were enforced to form a safe and high quality housing stock and to form a long-service-life housing respectively. Despite of the favorable background for wood protection sector, the amount of treated wood was steadily decreasing to 202,057 m3 till 2008 from the maximum of 445,689 m3 in 1996 (JWPIA: Japan Wood Preservers Industry Association statistics).

Several keywords are exterior wood products which can improve the landscape of housing area, treated wood products which can decrease the construction cost of house/year from prolonged service life of housing, local wood products which can mitigate climate change through lower embedded energy of sustainable local resources. It also requires integrated strategy to realize the increased utilization of these wood products.
