Japan considers minesweeping in Hormuz if ceasefire is reached

Sunday 22 March 2026 - 10:00

Japan has indicated it could consider a limited military role in securing the Strait of Hormuz, one of the world’s most critical energy corridors, but only under the condition of a ceasefire in the ongoing tensions involving Iran.

Speaking in a televised interview, Toshimitsu Motegi explained that any potential deployment of Japan’s Self-Defense Forces would remain hypothetical and strictly tied to post-conflict stabilization efforts, such as clearing naval mines that could obstruct maritime traffic.

The narrow strait handles a significant share of global oil shipments, making it vital not only for regional stability but also for the global economy. For Japan, the stakes are particularly high, as the country relies heavily on energy imports passing through this route.

Despite the possibility raised, Japanese authorities emphasized that no immediate plans are in place to deploy forces or negotiate specific passage arrangements for vessels. Officials stressed that ensuring safe navigation for all ships remains a priority, especially as disruptions in the strait have already impacted global markets.

Japan’s military posture remains constrained by its pacifist constitution, although legal reforms adopted in recent years allow limited overseas operations when national security is at risk or when key allies are involved.

Diplomatic efforts are ongoing. Iranian Foreign Minister Abbas Araqchi has reportedly discussed the issue with Tokyo, including the possibility of facilitating the passage of Japan-linked vessels through the strategic passage.

Meanwhile, Donald Trump has urged allies, including Japan, to take a more active role in securing maritime routes. During recent talks with Japanese Prime Minister Sanae Takaichi, the issue of Hormuz security was a key topic, reflecting broader international concern over energy supply disruptions.

As geopolitical tensions persist, Japan appears to be carefully balancing its constitutional limits with the growing need to protect vital economic interests tied to global energy flows.
