Japan's Prime Minister Kishida Fumio has wrapped up an eventful seven-day visit to the United States.

Kishida held a summit with US President Joe Biden in Washington on Wednesday. The two leaders agreed to deepen defense cooperation and strengthen collaboration in a wide range of areas such as economic security and space.

On Thursday, Kishida addressed a joint session of the US Congress. He stressed that Japan will bear greater responsibility in maintaining global order based on freedom and democracy.

The prime minister also attended a trilateral summit with the US and the Philippines. The three leaders agreed to increase maritime security cooperation in response to China's activities in the South China Sea and the East China Sea.

Kishida then visited Toyota and Honda automobile factories in North Carolina.

The prime minister spoke to reporters before leaving the US. He said he was able to send a message to Congress, the American people and the world about what kind of future Japan and the US, as partners, are going to pass on to the next generation.

Kishida was the first Japanese prime minister in nine years to receive hospitality normally reserved for a state guest. He left the US on a return flight early on Sunday morning, Japan time.
