In the fiscal year 2022, the electricity costs for homes amounted to 34 Japanese yen per kilowatt hour. The electricity costs increased multiple times since fiscal year 2016, when the figure stood at 24.31 yen per kilowatt hours.  Competition in the electricity market remains limited The competition in the Japanese electricity market remains limited as it continues to be dominated by ten regional electric utilities. Retailers of low voltage electricity mainly sell their electricity locally to homes or small shops. Tokyo Electric Power Co., Inc., also known as TEPCO, continued to rank as the largest electric power company in Japan in terms of total assets. The electric company is known for the nuclear accident at its Fukushima Daiichi Nuclear Power Plant in 2011.  Causes for rising electricity costs After the nuclear disaster, nuclear energy was replaced by fossil fuels. Since Japan lacks domestic reserves of fossil fuels, it heavily depends on imports. Consequently, the self-sufficiency rate of primary energy decreased shortly after the disaster, causing electricity costs to rise. Additionally, in recent years, a short supply of liquefied natural gas (LNG) reinforced the price increase.

For fiscal year 2025, the FIT price of electricity that is generated from solar energy in Japan was set at ten Japanese yen per kilowatt hour.The feed-in tariff (FIT) system is a national system under which the unit price of electricity is fixed by the country. It is designed to increase investments in renewable energy systems by providing price certainty and long-term contracts to renewable energy producers.  Solar energy is the largest renewable energy source in Japan In recent years, solar energy overtook hydropower as the largest renewable energy source in Japan. The generation capacity of solar energy continues to rise as the Japanese government made investments in solar power a priority. As the island nation strives to become carbon neutral by 2050, it aims to increase its share of renewables and nuclear power. Consequently, the share of renewables in electricity production has increased to over 20 percent in recent years.  Solar energy prices keep decreasing In 2015, the government started to cut the FIT-based purchase price of electricity generated from solar energy. Since the sales price of solar photovoltaic (PV) modules has decreased as well, this resulted in a long-term decline in solar power costs. The Ministry of Economy, Trade, and Industry (METI) estimated that solar power will become cheaper than nuclear power by 2030.
