As of April 22, 2025, Japan Prime Minister Ishiba Shigeru announced fixed price cuts on gasoline starting in May 2025. Prices will be lowered by 10 yen, or about 7 cents per liter starting in May. [1] The decision follows a proposal made by the Liberal Democratic Party and the Komeito Party on how to respond to the US tariff measures. In response, the government intends to take immediate action by restructuring the current fuel oil price drastic change mitigation measures and implementing the fixed price reduction measures to address the “old provisional tax rate.” Prime Minister Ishiba stated that diesel oil will be cut by 10 yen per liter, heavy oil and kerosene by 5 yen, and aviation fuel by 4 yen. These measures will be implemented from May 22nd onwards. Additionally, he announced that steps will be taken to support consumers’ electricity and gas bill for 3 months of summer in July, August, and September, when electricity demand usually rises.
