U.S. Secretary of Defense Pete Hegseth announced Sunday a plan to upgrade the U.S. military command in Japan, a country he described as indispensable in combating Chinese aggression.

“We share a warrior ethos that defines our forces,” Hegseth told Japanese Defense Minister Gen Nakatani in Tokyo, adding that Japan is “our indispensable partner” in “deterring communist Chinese military aggression,” including across the Taiwan Strait.

Hegseth said Japan is a “cornerstone of peace and security in the Indo-Pacific” and that the Trump administration would continue to work closely with the Asian country.

Hegseth and Nakatani agreed to accelerate a plan to jointly produce beyond-visual-range air-to-air AMRAAM missiles and to consider working together on the production of SM-6 surface-to-air defense missiles to support a shortage of munitions, Nakatani said.

The Pentagon chief said he asked Nakatani for greater access to Japan’s strategic southwest islands, along the edge of the contested East China Sea near Taiwan.

In his first official visit to Asia, Hegseth traveled to Japan from the Philippines.

On Saturday, he attended a memorial service on Iwo Jima, the site of fighting between U.S. and Japanese forces 80 years ago.
