Electricity demand Japan FY 2023, by region

In the fiscal year 2021, the Tokyo region had the highest demand for electricity in Japan, with approximately 279.31 thousand gigawatt hours. The Kansai region followed, with an electricity demand of almost 139.87 thousand gigawatt hours.

 Manufacturing had the highest energy demand

The capital Tokyo was the region with the highest electricity demand on the archipelago. Likely because it is one of the world’s most populated cities and the largest industrial region in Japan. As one of the global leaders in the manufacturing industry, Japan has a high energy demand for its production. Consequently, manufacturing was by far the leading industry to consume energy.

Energy mix in Japan

In Japan, fossil fuels such as natural gas and coal continued to represent the leading sources of electricity production. However, the country relies on imports of fossil fuels. Therefore, Japan’s current energy policy aims to diversify its energy mix to secure a stable energy supply, reduce electric power costs, and decrease greenhouse gas emissions.
In recent years, the share of renewables in electricity production increased to over 20 percent, with solar and hydropower representing the largest renewable energy sources.
