Japan will welcome overseas tourists after June 10th.

Japan will ease the restriction of overseas tourists after 10th. 20,000 per day, then hopefully 30,000 day in June or July. Countries are labeled green, yellow, red. People from Green countries don't need to take vaccines, or take test on arrival day in Japan. You still need to have visa. Only pre-scheduled tour are allowed. So let the travel agencies handle your trips to Japan.
