Japanese Power and City Gas Suppliers to Raise Rates in October Following End of Government Subsidies

Executive Summary

In September 2025, the Japanese government concluded its subsidy program that had been in place from July through September to alleviate energy costs for households. This program provided subsidies of up to ¥2.4 per kilowatt-hour for electricity and ¥10 per cubic meter for city gas, effectively reducing monthly energy bills by approximately ¥3,000. Following the end of this subsidy, major power and city gas suppliers in Japan announced rate increases effective from October 2025. Ten power suppliers stated they would raise electricity rates by ¥467 to ¥536 for average households compared to the subsidized period, with Tokyo Electric Power Company Holdings (TEPCO) increasing rates by ¥520 to a new average of ¥8,652. Similarly, four city gas companies plan to raise rates by ¥172 to ¥222 per average household, with Tokyo Gas expected to increase rates by ¥222 to ¥5,710. These adjustments reflect the removal of government support and are expected to impact household energy expenses nationwide.

Situation

The government subsidy program was introduced as a temporary measure from July to September 2025 to mitigate the financial burden on consumers amid rising energy costs. The subsidies helped reduce monthly fees by about ¥3,000, providing relief during the summer months when energy consumption typically increases. As the subsidy period ended in September, suppliers prepared to revert to market-based pricing, leading to announced rate hikes effective October 2025. TEPCO and other suppliers communicated these changes to consumers, emphasizing the direct correlation with subsidy withdrawal. The timeline shows a government intervention during peak consumption months, followed by a return to standard pricing. National responses have included public communications from energy companies and government explanations about the necessity of subsidy removal due to budgetary constraints and market conditions. Key figures, including representatives from TEPCO and Tokyo Gas, have acknowledged the rate increases while urging consumers to adopt energy-saving measures.

International Impact

While the rate increases are primarily a domestic issue, they reflect broader global energy market trends, including fluctuations in fuel prices and supply chain challenges. The subsidy program and its conclusion highlight Japan's efforts to balance consumer protection with fiscal responsibility. Internationally, such adjustments may influence Japan's energy import strategies and negotiations with energy-exporting countries. Global leaders and energy analysts observe Japan's approach as indicative of challenges faced by developed nations in managing energy costs amid volatile markets. No direct statements from international leaders were noted, but the situation underscores the interconnectedness of global energy economics.

Decision Maker Perspectives

Japanese Government: Implemented temporary subsidies to ease energy costs during peak months but ended the program due to fiscal and market considerations, leading to rate increases.

Tokyo Electric Power Company Holdings (TEPCO): Announced rate hikes following subsidy removal, emphasizing the need to align prices with actual market costs.

Tokyo Gas: Prepared to raise city gas rates in line with subsidy cessation, communicating changes to customers while encouraging energy conservation.
