Tokyo’s mission to evacuate its nationals from Wuhan, the Chinese city at the center of a coronavirus outbreak, got underway Tuesday, as Japan reported its first case not linked to recent travel to China.

One of three new cases reported in Japan on Tuesday is a male bus driver in his 60s who lives in Nara Prefecture. The man did not travel to Wuhan but drove buses with tour groups from the city twice this month, officials said. The man is the first Japanese confirmed to be infected with the new coronavirus while this is also the first human-to-human transmission confirmed in Japan.

The other two patients, a man and woman in their 40s, are from Wuhan and their conditions are not serious, according to the health ministry. Japan has now reported a total of seven cases.

Meanwhile, a chartered flight departed Tokyo later Tuesday for Wuhan, the Chinese city at the epicenter of the deadly outbreak.

Foreign Minister Toshimitsu Motegi told reporters Tuesday that the plane would deliver masks and protective suits to Wuhan before carrying back some 200 people to Tokyo on Wednesday morning. About 650 Japanese have expressed a desire to return to Japan, and the government is making arrangements to send additional chartered flights to Wuhan, Motegi said.
