Japanese troops to train with Australian, US militaries in Darwin

Japanese troops will begin regular deployments in northern Australia as part of military cooperation with Australia and the US, Australia's Defence Minister Richard Marles said on Sunday.

Around 2,000 US Marines are already hosted in Darwin, the capital of the Northern Territory, for six months of the year amid growing concern among Washington and its allies about China's growing military power in the Indo Pacific region.

"Today we are announcing that there will be regular deployments of Japan's amphibious Rapid Deployment Brigade to Australia," Marles said at a televised press conference in Darwin, alongside US Defence Secretary Lloyd Austin and Japanese Defence Minister Gen Nakatani.

"Having a more forward leaning opportunity for greater training with Japan and the US together is a really fantastic opportunity for our defence," Marles told Sky News on Sunday, according to a transcript.

The deployment has special significance given Darwin was a major base for Allied forces in World War II and was heavily bombed by Japanese forces. The wartime air raids on the port city are sometimes described as Australia's Pearl Harbour.

Austin said on Sunday he was confident the US will provide the capabilities set out in the AUKUS deal, which will see Australia buy U.S. nuclear submarines and develop a new class of nuclear-powered submarines with the U.S. and Britain.

China, building its military capacity in the Indo Pacific, in September carried out the rare launch of intercontinental ballistic missile that landed in the Pacific Ocean. The test launch was described as concerning by several Pacific nations, including Australia.
