Japan has indicated that it may consider deploying its Self-Defense Forces for minesweeping operations in the Strait of Hormuz, but only under specific conditions—most notably, if a ceasefire is achieved in the ongoing US-Israeli conflict with Iran.
Foreign Minister Toshimitsu Motegi stated that such a move remains purely hypothetical at this stage. He explained that if hostilities were to end and naval mines posed a threat to safe navigation, Japan could evaluate the possibility of undertaking minesweeping activities to restore maritime access.
Japan’s ability to engage in overseas military operations is constrained by its postwar pacifist constitution. However, security legislation passed in 2015 allows limited deployment of its Self-Defense Forces abroad if a situation threatens the country’s survival or significantly impacts its security interests, especially when no alternative measures are available.
Despite concerns over disrupted shipping, Motegi clarified that Japan currently has no immediate plans to pursue special arrangements for stranded Japanese vessels in the Strait of Hormuz. He stressed that the priority is to create conditions that ensure safe and unrestricted passage for all ships through the strategically critical waterway.
The issue holds particular importance for Japan, as nearly 90 percent of its oil imports pass through the strait. Ongoing tensions and restricted access have already contributed to rising global oil prices, prompting Japan and other nations to tap into their strategic reserves.
Diplomatic efforts are also underway. Iran’s Foreign Minister Abbas Araqchi recently held discussions with Motegi regarding the possibility of allowing vessels linked to Japan to pass through the strait. Meanwhile, US President Donald Trump has urged Japan to play a more active role in ensuring maritime security in the region, including contributing naval support.
Following talks in Washington, Japanese Prime Minister Sanae Takaichi stated that she had outlined to the US what kind of assistance Japan can legally provide under its current framework, highlighting the balance Tokyo is trying to maintain between its security commitments and constitutional limitations.
Overall, Japan’s position reflects a cautious approach—remaining open to limited involvement if conditions permit, while prioritising diplomacy and adherence to its legal constraints.
