Via the Japanese press:
A sudden spike in new coronavirus cases was confirmed among attendees at a New Year’s party for independent taxi drivers held on a traditional “yakatabune” river tour boat in the capital.
The Tokyo Metropolitan Government says the virus may be spreading in the capital, as people not at the party — including an office worker and a chauffeur — were also confirmed infected, and is calling for measures to prevent transmission. It provided information on the route of infection among party attendees at a Feb. 16 press conference.
