Japan could consider Hormuz minesweeping if ceasefire reached, minister says

Japan's Foreign Minister Toshimitsu Motegi indicated on Sunday, March 22, 2026, that Tokyo might contemplate deploying its Self-Defense Forces for minesweeping operations in the Strait of Hormuz. This potential action is contingent upon a ceasefire in the ongoing U.S.-Israeli conflict with Iran. The Strait of Hormuz is a critical maritime chokepoint, facilitating the passage of approximately one-fifth of global oil supplies.

Motegi underscored that any such consideration remains hypothetical, directly linked to a complete cessation of hostilities in the region. The strait has experienced significant disruptions over the past four weeks due to the conflict, contributing to a notable increase in international oil prices. Japan is particularly reliant on this waterway, with roughly 90% of its oil imports transiting through it.

Country Impact: Japan's potential military deployment would mark a significant shift in its post-war defense policy, balancing constitutional pacifism with energy security needs. It could also elevate Japan's role in regional security, particularly in the Middle East.

Industry Impact: The oil and shipping industries face continued volatility due to disruptions in the Strait of Hormuz. A successful minesweeping operation could stabilize oil prices and ensure smoother maritime trade, benefiting global supply chains.

Market Impact: Global energy markets, particularly crude oil futures, would likely react positively to any concrete steps towards reopening the Strait of Hormuz. Reduced geopolitical risk in the region could also bolster investor confidence in broader financial markets.
