The cornerstone of Biden's visit, which includes meetings with the leaders of Japan, India and Australia, in the "Quad" group, will be the launch of an Indo-Pacific Economic Framework, a broad plan providing an economic pillar for US engagement with Asia.

"The US-Japan alliance has long been the cornerstone of peace and prosperity in the Indo-Pacific, and the United States remains fully committed to Japan's defence," Biden said at the beginning of talks with Kishida at the Akasaka Palace in central Tokyo.

Biden was greeted with a military honour guard that played the anthems of both countries under a bright blue sky.
