Japanese and US forces launch largest joint military exercise in Japan's southwestern islands

Japanese and US forces have launched one of their largest joint military exercises, focusing on defending Japan's southwestern islands in a show of strength amidst rising tensions in the region.

The biennial Keen Sword 27 exercise brings together over 45,000 Japanese troops and 12,000 American service members for a series of drills that will run until October 29. The scale of the joint operation is significant, with both countries committing large numbers of personnel to the effort.

Seven other nations from the Indo-Pacific region and Europe are also participating in some aspects of the exercises, marking a new level of international cooperation in the region. Five of these countries, France, Germany, the Netherlands, New Zealand, and the Philippines, are making their first appearance in Keen Sword 27.

The Japanese government has been keen to highlight the importance of the exercise, citing growing concerns about regional security. The country's southwestern islands have become a focal point for military planning due to their strategic location and proximity to potential flashpoints.

As part of the exercises, troops will be conducting a range of drills including amphibious landings, air defense operations, and mine sweeping on several remote islands, including Tanegashima.

The joint military drills between Japan and the US are taking place around various islands in the region, with Yonaguni being a key location. This island is situated just 110 kilometers east of Taiwan, which China considers its own territory.

The exercises have seen the introduction of advanced weaponry to Yonaguni, including Japan's first long-range Type-25 land-to-ship missile. Capable of reaching mainland China with a range of approximately 1,000 kilometers, this missile is set to boost the island's defense capabilities.

A range of US military systems has also been deployed to Yonaguni for the exercises, including NMESIS and MADIS. These systems are designed to counter potential threats from the sea, while a mobile rocket launching system, HIMARS, has been stationed on the nearby island of Ishigaki.

The drills are part of a broader effort to enhance regional security in the face of rising tensions. Gen. Hiroaki Uchikura, Japan's Chief of Staff, denied that the exercises were specifically targeting any country, but emphasized the importance of being prepared and cooperating with allies.

On Monday, live fire exercises were set to take place on Oki-Daito, a small island in the Pacific Ocean southeast of Okinawa. The drills are designed to test the military's readiness and coordination with international partners, as Japan's Maritime Self-Defense Force Adm. Tateki Tawara highlighted the need for preparedness to protect peaceful lives and territory.

The joint military exercises between Japan and the US have begun, taking place in the region surrounding disputed islands in the Pacific Ocean. This development comes at a time when tensions between Tokyo and Beijing are running high, following a comment made by Japanese Prime Minister Sanae Takaichi last year.

Her statement suggested that Chinese military action on Taiwan could justify Japanese involvement, sparking anger from China and leading to strained relations. The situation has further escalated with China's gradual increase in military activity around the remote Japanese islands. This has raised concerns for Japan about potential threats to its territory.

The exercises are taking place just weeks after a US Marine was arrested in connection with a murder and robbery on Okinawa, where thousands of US troops are stationed. The incident has reignited protests against the presence of US bases on the island, which have long been a source of contention among residents due to noise, pollution, and crime.

The exercises will involve significant military assets, including aircraft carriers like the USS Theodore Roosevelt, which recently arrived at the Yokosuka base in Japan. Local authorities have expressed concerns about the adherence of US personnel to Japanese rules, with mayor Katsuaki Kamiji requesting that the importance of compliance be conveyed to the US military through diplomatic channels.
