Japan's Maritime Self-Defense Force has held an international fleet review for the first time in 20 years, to mark the 70th anniversary of its founding.

Twenty MSDF destroyers and submarines as well as 18 vessels from the United States, South Korea and 10 other countries took part in the review on Sunday in Sagami Bay, south of Tokyo.

This was the second time the international fleet review was held in Japan.

Japan did not invite Russia to the event, while China did not take part despite being invited by Japan.

Japan's Prime Minister Kishida Fumio observed MSDF vessels and those from other countries sailing in formation from the deck of the MSDF destroyer Izumo.

Kishida strongly criticized Russia and North Korea in a speech. He also reiterated his government's policy of aiming to drastically strengthen Japan's defense capabilities.

The prime minister said that in order to protect the public and ensure peace and stability in the region, it is fundamental to seek the building of a stable international order through dialogue.

But he noted that it is also necessary to prepare for a situation where peace and security is violated by military force, adding that he will give realistic consideration to the issue without ruling out any options.

Kishida and Defense Minister Hamada Yasukazu later visited the US nuclear-powered aircraft carrier, the USS Ronald Reagan, and inspected the deck lined with fighter jets.
