One case of monkeypox has been identified in Tokyo, Japan’s Health Ministry and the Tokyo metropolitan government confirmed on Monday.

The case involved a man in his 30s who had recently returned from Europe. The ministry said the patient had close contact with someone who was later diagnosed with monkeypox before returning to Tokyo in mid-July.
