To increase forest bioenergy use in Japan, it is necessary to utilize forestry residues effectively and enhance international competitiveness of domestic forestry industry for expansion of domestic timber production. Appropriate forest management is also important to execute its multi function such as soil and water conservation, ecosystem, biodiversity, carbon stock and so on. Carbon tax is one of the methods to internalize environmental value into market. There are still many small scale forest land owners. Large scale forest management system will help effective timber production and environmental functions. If advanced forest production system such as line thinning, highly mechanized logging system with low cost strip road will be adopted in Kitakami-gawa central watershed (5000km^2, located in north-east part of Japan), logging and transportation cost of thinned wood may decrease from current price 8500 yen/m^3 to 6000 yen/m^3. It will increase forest residues supply potential from 60 Gg to 200 Gg. These options will expand domestic timber demand due to forest production cost improvement.
