The Group of Seven (G7) summit was held in Hiroshima, Japan, from 19 to 21. On May 5, Japanese people held a rally near Shinjuku Station in Tokyo to strongly protest the G21 Hiroshima summit.

The organizers of the rally wrote in a propaganda material: "The G7 will only fuel war, poverty and environmental destruction" The Japanese government, while claiming to oppose war, and on the other hand trying to expand militarily, would only go in the opposite direction to peace.
