Now, with the Biden administration in place and with China growing increasingly assertive, Japan seems more willing to join with the United States in its unequivocal criticism of China’s actions.
Mr. Kishi, the defense minister, said that Japan could “absolutely not accept” China’s actions to increase tensions in the East and South China Seas, and indicated they were violating international laws.
Yet the Japanese foreign minister, Toshimitsu Motegi, was less overt in criticizing China.
While Mr. Blinken explicitly singled out China — and Myanmar, where the military staged a coup last month — for threatening “democracy, human rights and rule of law,” Mr. Motegi avoided mentioning China directly. He said that he welcomed the alliance for its role in protecting “peace and prosperity in the Indo-Pacific.”
Analysts said Japan may temper its language because it has more to lose from confrontation with China.
“One big difference is their economic relationships with China,” said Narushige Michishita, vice president of the National Graduate Institute for Policy Studies in Tokyo. “While the U.S. can live without China, Japan cannot. They have to find a common ground there.”
The high-level visit from Washington sought, in part, to remind Japan that it shares much common ground with the United States. That it was the first official trip overseas for both Mr. Blinken and Mr. Austin since taking office was repeated several times on Tuesday to assure Japan of its value to the Biden administration.
The alliance with Japan never suffered as much damage under the Trump administration as U.S. partnerships in Europe. Mr. Abe maintained a close relationship with Mr. Trump and hosted him for two visits to Japan. Last October, when then-Secretary of State Mike Pompeo met with Prime Minister Yoshihide Suga, the two exchanged a fist bump that lasted 15 seconds.
On Tuesday, when Mr. Suga met with Mr. Austin and Mr. Blinken at his official residence, they all bowed — as is the custom in Japan.
