Tokyo, March 22: Japan’s Foreign Minister Toshimitsu Motegi recently hinted at a military operation that may appear to be a “cleanup” but is, in reality, highly dangerous and technically complex. The discussion revolves around “mine sweeping” in the Strait of Hormuz, which involves removing explosive mines laid in the sea.
The Strait of Hormuz is considered one of the world’s most crucial maritime routes, through which a significant portion of global oil supply passes. If mines are laid in this area, it poses not only a military threat but could also deliver a severe blow to the global economy. This is why Japan has clearly stated that it may consider deploying its military resources to remove mines and secure this waterway if a ceasefire occurs between the United States-Israel and Iran.
The question arises: what exactly is “mine sweeping”? Mines laid in the sea act like hidden bombs for any ship. They can be activated by collision, the ship’s magnetic field, or even its noise. Specialized ships, helicopters, and even underwater robots are used to remove these mines.
In some cases, ships drag cables through the water, capturing the mines and cutting their hold, allowing them to rise to the surface for remote destruction. Modern technology involves first locating mines using sonar, followed by robots that deactivate them—essentially functioning as a bomb disposal unit underwater.
Historically, this is not a new concept. During World War II, so many mines were laid in the oceans that the removal process continued for many years after the war ended. Similarly, under Operation End Sweep, the United States cleared maritime routes after the Vietnam War to resume shipping activities.
Japan is regarded as a top-tier expert in naval mine sweeping, with capabilities considered among the best in the world. As an island nation, Japan has developed a specialized Maritime Self-Defense Force (JMSDF) mine-sweeping fleet designed to keep maritime routes open.
Japan possesses advanced mine-sweeping ships, including the Awaji-class designed for deep-water operations and Mogami-class frigates equipped with advanced unmanned systems for detecting and neutralizing mines.
This indication from Japan is significant as it is an energy-dependent country, with a large portion of its oil imports coming through this route. If this passage becomes unsafe, it directly impacts Japan’s economy. Therefore, this move is not only about military cooperation but also about protecting its economic interests.
