Prime Minister Sanae Takaichi and opposition leaders held the first party leader debate of the current Diet session on Wednesday [1].

The debate centers on the urgent need for a supplementary budget to address rising energy costs and instability in the Middle East. Failure to secure these funds could leave Japanese households vulnerable to spikes in fuel and electricity prices during the summer months.

The session began at 3 p.m. in the National Diet main chamber [2]. Yuichiro Tamaki, leader of the Democratic Party for the People, criticized the government for delaying its decision on fiscal measures. Tamaki said the government should promptly organize a supplementary budget of approximately 3 trillion yen [1] to extend gasoline subsidies, and address electricity and gas costs for the summer.

Prime Minister Takaichi said the government is considering a supplementary budget to handle the current situation in the Middle East if the existing budget proves insufficient [3]. She said she was not yet in a position to provide specific details or the exact scale of the proposed spending [3].

Opposition members argued that the administration's hesitation is a failure of leadership. They pointed to the volatility of global energy markets as a reason for immediate action, rather than waiting for the current budget to be exhausted.

The discussion also touched upon the potential review of gasoline subsidies. While the government has historically used these subsidies to suppress price hikes at the pump, the debate highlighted a tension between short-term relief, and long-term fiscal sustainability.

Despite reports from some outlets suggesting the debate was postponed due to the prime minister's diplomatic schedule, records from the session confirm the meeting took place as scheduled [1], [2].

““I believe a supplementary budget of about 3 trillion yen should be promptly organized,” said Yuichiro Tamaki.”

This confrontation signals a growing legislative divide over Japan's economic response to geopolitical instability. By pushing for a specific 3 trillion yen figure, the opposition is attempting to force the Takaichi administration into a concrete fiscal commitment, moving the conversation from general 'consideration' to measurable public spending.
