Japan's Prime Minister Kishida Fumio is holding summit talks with US President Joe Biden at the White House.
Kishida is visiting the United States on the last leg of his tour of five Group of Seven nations. Japan holds the presidency of the G7 this year and will host its summit in Hiroshima in May.
During their bilateral meeting, Kishida and Biden are expected to reaffirm the unity of the G7 as the world faces such challenges as Russia's invasion of Ukraine and food and energy crises.
Kishida plans to brief Biden on a major shift in Japan's security policy announced last month. The changes include large defense budget increases and the capability to launch counterstrikes.
Kishida, with China's increasingly assertive moves in mind, wants to show Japan and the US are on the same page in their security strategies and are ready to bolster the deterrence and response capabilities of their bilateral security alliance.
The two leaders are also expected to confirm tighter bilateral cooperation in economic security, including the development of cutting-edge technologies like semiconductors, quantum computing and biotechnology.
