Takaichi will be the first major ally to hold face-to-face talks with Trump since he urged Japan and other partners to send naval vessels to escort tankers through the strategically vital waterway, which has been largely disrupted by Iran during the conflict.

“The biggest risk is that Trump publicly presses her for security commitments that she can’t deliver on,” said David Boling of the Asia Group consultancy in Tokyo, a former U.S. trade negotiator with Japan.

The Strait of Hormuz handles roughly a fifth of global energy supplies, with about 90% of Japan’s crude oil imports passing through it, underscoring Tokyo’s exposure to the crisis.

Japanese officials said Takaichi had initially planned to steer discussions toward concerns over China’s regional posture ahead of a delayed visit, but shifting U.S. priorities have forced a focus on Iran and maritime security.

Japan has received no formal request from Washington, Takaichi told parliament earlier this week, adding that the government was assessing possible responses within the constraints of its pacifist constitution.

Several U.S. allies, including Germany, Italy and Spain, have ruled out joining a Gulf mission. Kaja Kallas said on Tuesday that no country was prepared to risk personnel in the conflict zone.

Public sentiment in Japan also remains cautious. Fewer than 10% of respondents support U.S. and Israeli strikes on Iran, according to a poll by the Asahi newspaper.

Trump has alternated between criticising allies for their reluctance and downplaying their necessity, singling out countries like Japan that rely on U.S. security guarantees while depending heavily on Middle Eastern oil flows.

Tokyo has historically limited its role in Middle East operations to logistical and intelligence support. Analysts say deploying Japanese vessels into an active conflict zone would face significant legal and political hurdles.

“It has turned into a discussion that shakes the very foundations of the Japan–U.S. security alliance,” said Kazuhiro Maeshima, a politics professor at Sophia University in Tokyo.

Her remarks came as Seoul and Washington proceeded with their annual joint military exercises, which the two allies say are designed to strengthen defensive readiness against potential threats from North Korea.

Kim Yo Jong described the military exercises as provocative and warned they could undermine security in the region. Statements from North Korean officials have frequently portrayed joint U.S.-South Korean military activities as rehearsals for invasion.

The criticism reflects longstanding opposition from Pyongyang to the annual exercises, which typically involve large-scale troop deployments and coordinated operations between the two militaries.

Officials in South Korea and the United States maintain that the drills are defensive in nature and aimed at ensuring readiness and coordination between allied forces.

The exercises form a central component of the long-standing military alliance between the two countries, which maintains a substantial U.S. troop presence on the Korean Peninsula.

Analysts say North Korea’s leadership remains focused on maintaining strong deterrence capabilities amid shifting geopolitical tensions. One analyst said Pyongyang is determined not to face the same fate as Iran amid the ongoing conflict involving the United States and its allies.

The comments come as regional tensions remain elevated amid global security concerns and ongoing military activity across several geopolitical flashpoints.

The official declined to confirm the total value of the agreement. Details regarding the number of missiles or delivery timelines were not immediately disclosed.

Indonesian authorities confirmed that an agreement had been reached with India for the supersonic cruise missile system, but provided few additional specifics on the scope of the procurement.

Requests for comment sent to BrahMos Aerospace and India’s Ministry of Defence (India) were not immediately answered.

The missile system secured its first foreign export contract in 2022 with the Philippines, a Southeast Asian neighbour of Indonesia. That agreement marked a milestone for India’s defence exports and established the BrahMos system as a product available to overseas buyers.

The BrahMos missile, jointly developed by India and Russia, is designed as a supersonic cruise missile capable of being launched from land, sea or air platforms.
