In Japan, the energy use of wood residue has been paid attention in the background of the global warming prevention and the rise of the oil price. In this paper, the current situation in generation and utilization of wood residue was reported. The total amount of wood residue from wood industry (sawmill, plywood mill, glulam factory, precut factory) was estimated to be 10,782,000m^3 in 2005 and most of them was used for wood chip for paper, livestock bedding, fuel for boilers, etc. The total amount of wood residue from construction was estimated to be 4,710,000t in 2005 and 68.2% of them was used for paper, board, compost, fuel for boilers as the recycled wood chip. The insufficiency of the recycled wood chip becomes problem because the energy use of it have rapidly increased. On the other hand, the total amount of forest residue was estimated to be 3,900,000t and most of them was not used. Although the utilization of forest residue is examined it is necessary to decrease the supply cost of it.
