The Japaneses Self-Defense Forces (SDF) exercised amphibious landings this month with U.S. forces in Hawaii, according to the Associated Press. The Japanese military has emphasized amphibious landings recently as tensions have risen with China over the sovereignty of the Senkaku/Diaoyu Islands specifically and more generally in the region. In any scenario where Tokyo would have to reclaim territory it currently administers through the use of military force, it would need to be ready for an amphibious landing — one of the toughest imaginable scenarios for a modern military.
The exercise took place on the sidelines of the broader RIMPAC 2014 maritime exercise, which is also taking place in the waters off Hawaii this month. According to the AP, “Helicopters dropped a reconnaissance team of Japanese soldiers into the ocean off a beach at a U.S. Marine Corps base during Rim of the Pacific exercises on Tuesday. The soldiers climbed aboard inflatable rafts and inspected the shoreline before waves of U.S., Australian and Indonesian marines followed in amphibious vehicles.”
Japan first drew attention to its interest in honing the SDF’s capability to wage amphibious warfare last October when it announced an exercise involving 34,000 troops performing a similar drill in Okinawa. The SDF’s interest in island warfare clearly stems from the possibility of conflict with China over disputed islets in the East China Sea.Enjoying this article?

The Naval Diplomat, James Holmes, describes “seizing an island held by dug-in invaders” as one of the “stiffest challenges amphibious forces face.” For the Japanese military, the prospect of retaking an island is very real, hence the emphasis during the last year on amphibious landing exercises. Additionally, with the Japanese government’s recent decision to pass a resolution reinterpretating the Japanese constitution’s ban on collective self-defense, Japanese forces may find themselves fighting outside of their immediate neighborhood.
Brad Glosserman, executive director of CSIS’s Pacific Forum, told the AP that by participating in these exercises, Japan is additionally communicating to the United States “the value of Japan as a partner, as an ally, and as a country that’s prepared to defend itself and be ready to defend its own territory which the United States is also obliged to defend.”
