USNI News – Japan’s defense minister raised concerns about Russia’s recent naval activities in the Sea of Japan, citing the size of the exercise and increased tension with Ukraine.

Naval News – Since the signing of the Joint Declaration on Security Cooperation in 2007, Australia and Japan have grown closer through joint training exercises between the Japan Self-Defense Force (JSDF) and the Australian Defence Force (ADF). And the Australia-Japan relationship has entered a new chapter in recent years.

War Zone – The missiles would offer land-attack and anti-ship capabilities and would be expected to serve as a deterrent to China and North Korea.

Kyodo News – Japan’s Self-Defense Forces and the U.S. military have drawn up a draft joint operation plan that would enable the setup of an attack base along the Nansei island chain in the country’s southwest in the event of a Taiwan contingency.

War on the Rocks – The most important development for Taiwan’s security might be unfolding right now in Japan. Tokyo’s strategy toward Taiwan is dramatically shifting. Once reluctant to join all but the most anodyne of pro-Taiwan statements with the United States, Japanese officials now increasingly state their desire to “protect Taiwan as a democratic country.” While no formal changes in security policy or diplomatic legalities are likely, Tokyo is signaling that it is willing to support Taiwan’s sovereignty, up to and including joining a military defense of the island against Chinese attack. This is likely giving Chinese Communist Party leaders and military planners much more short-term heartburn than the recently announced submarine and technology sharing deal between Australia, the United Kingdom, and the United States.

War On The Rocks – As the United States increasingly focuses on competition in the Indo-Pacific, and as elements of the U.S. military look specifically to amphibious aircraft, it would do well to consider acquiring handy Japanese seaplanes.

War on the Rocks – Earlier this month, U.S. Marine Corps F-35B Lightning II fighters embarked on the Japanese Maritime Self Defense Force ship JS Izumo as a capability validation…It is also a milestone on a path that is establishing smaller aircraft carriers equipped with the F-35B Lightning II, or “Lightning carriers,” as the new capital ships of Asia.

CIMSEC – The broader DOD (USN) and MOD (JMSDF) must better leverage emerging technologies and developing concomitant warfare concepts (doctrines) to adapt to the new way of fighting. Otherwise, the United States and Japan risk ceding the technology domain and consequently military superiority in the Indo-Pacific to revisionist China and revanchist Russia.
