Diplomatic push urged by Japanese ruling parties following a two-week ceasefire agreement between the United States and Iran. Both ruling and opposition parties expressed relief over the truce. However, they also called for further government measures to ensure vessel safety. The opposition bloc demanded the compilation of a supplementary budget. Takayuki Kobayashi, chairperson of the LDP’s Policy Research Council, spoke on Wednesday at party headquarters. We view the agreement positively and welcome it, Kobayashi said.
Kobayashi expressed hope that the US-Iran talks will ensure navigation safety and de-escalate the situation. He referred to Japanese ships stranded in the Persian Gulf by Iran’s effective blockade of the Strait of Hormuz. I want the government to thoroughly pursue diplomatic efforts so that the vessels can leave the gulf as soon as possible, Kobayashi stated. Regarding a fiscal 2026 supplementary budget to address soaring crude oil prices, Kobayashi indicated any decision should hinge on whether the economic impact will be prolonged. He noted the need to carefully evaluate whether the ceasefire agreement is merely temporary or a step toward a permanent solution.
Fumitake Fujita, coleader of the Japan Innovation Party, spoke at a press conference. The party welcomes the agreement because safe navigation in the strait is a top priority. He added that the JIP intends to support the government in its de-escalation efforts. The LDP and JIP form the ruling coalition together.
Opposition parties have called for a supplementary budget, citing lingering economic anxiety. Motohisa Furukawa, acting leader of the Democratic Party for the People, expressed his view at a press conference on Wednesday. We are pleased about the agreement, but it is unclear whether the ceasefire will truly last, Furukawa said. He stressed the need for the government to take proactive steps. He called the compilation of a supplementary budget essential.
Masayo Tanabu, secretary general of the Constitutional Democratic Party of Japan, said the government’s measures against soaring fuel prices in the already enacted fiscal 2026 budget are completely insufficient. Komeito leader Toshiko Takeya asserted at a party meeting that Japan should not stop with the enactment of the initial budget and should immediately compile a supplementary budget. Japanese vessels remain stranded in the Persian Gulf. The ceasefire offers a temporary window for diplomatic engagement. Government officials will likely face continued pressure from all sides to act decisively. The coming weeks will determine whether the truce holds or hostilities resume.
