Speaking to parliament on Monday, multiple government officials denied the possibility of an immediate Self-Defense Forces deployment to the Strait of Hormuz — though they stopped short of ruling out the possibility altogether. But with U.S. President Donald Trump renewing his call to form a Hormuz coalition, discussions in Tokyo are sure to intensify.
Trump on Monday once again named Japan as a country he expects to participate in securing the critical Middle Eastern waterway, claiming that countries who receive “90 to 95% of their energy or their oil” through the strait “should be in here very happily helping us.” His remarks focused primarily on the deployment of minesweepers, a mission in which the SDF have top-tier capabilities.
Amidst this external pressure from Japan’s lone ally, the debate in Japan about the Iran war thus far has avoided bombast or hyperbole, and instead focused on legality and necessity. Prime Minister Sanae Takaichi’s administration has not yet issued any formal positions as it awaits a formal request from Washington.
The debate in Tokyo about the Iran war has largely centered around four issues.
First is the safety of Japanese nationals abroad. Takaichi has repeatedly stated her intent to prioritize the well-being of her countrymen, and her administration has been actively facilitating their evacuation. In total, the Foreign Ministry said that the government has supported the transit of more than 1,400 Japanese nationals — as well as over 50 foreign nationals —since the outbreak of hostilities.
The second is the impact on global oil markets and Japan’s economy. Opposition lawmakers point to rising gas prices as well as impacts from the government’s decisions related to strategic oil reserves. These debates are likely to continue as Tokyo navigates ongoing budget talks in the Upper House.
The third point is about what action the Japanese government can and should be taking in response. Aside from evacuation of Japanese nationals, there are three missions requiring SDF deployment that have received political attention: information gathering, escort of Japanese vessels and minesweeping.
The Takaichi administration has already indicated that it is discussing possible deployment of forces for information gathering, noting that its personnel could conduct their functions outside of the Persian Gulf amid the ongoing conflict.
The main discussions about escorting Japanese vessels have centered on whether this would require parliamentary or Cabinet approval. Under Japanese law, there is a provision for “Maritime Security Operations Orders” that could potentially allow for this. However, Defense Minister Shinjiro Koizumi pointed out that this is meant for the Maritime Self Defense Force to play a supplementary role when Japan’s law enforcement capabilities are insufficient. While Koizumi did not rule out the extension of an operations order, there…
