Before the war, Japanese household energy was mainly relying on firewood, and the usage ratio of firewood until the 1920s was over 80%. Forest energy including Charcoal took 3/4 of the all type of energy (this data is based on supply , therefore the importance of firewood and charcoal is slightly exaggerated).
The increase of electricity usage was remarkable from the 1910s to the 1920s, then in the 1930s the alternative charcoal has increased. The Energy consumption in urban area has smoothly increased in the 1990s and the energy resource also became diversified. Compared to rural area, the usage ration of charcoal is high which was consumed as much as firewood.
