Hundreds of people rallied at Tokyo's Shiba Park on May 22 to protest U.S. President Joe Biden's three-day visit to Japan, as international tensions are running high over the Russia-Ukraine conflict.

Biden arrived in Japan on Sunday and is set to attend a summit on May 24 where he will meet Japanese Prime Minister Fumio Kishida, Indian Prime Minister Narendra Modi and Australian Prime Minister Scott Morrison to promote the "Quad" mechanism.

The Quad, officially the Quadrilateral Security Dialogue, was initiated in 2007 by then Japanese Prime Minister Shinzo Abe and supported by then leaders of the U.S., India and Australia.

"I oppose Biden's visit to Japan. I think it will bring about a new crisis to Asia. I think the U.S.-Japan alliance aims to dominate Asia by military operations. Now the alliance is planning to gradually involve Japan and its Self-Defense Force in wars," said Ryusuke Motoyama, a member of the Bureau of Affairs of the Executive Commission for Preventing Constitutional Amendment for War.
