Due to the scarcity of energy resources in Japan, electric power rates are largely influenced by imported fuel oil prices. In fact, the rates have been linked to the prices of fuels such as crude oil and LNG. Fuel oil prices were relatively stable for several years, but increased in 2020 and 2021, which impacted the current power rates.
