Tokyo’s new coronavirus cases climbed to 55, public broadcaster NHK said, the highest tally in 1.5 months after a cluster of infections was found at an unnamed office in the Japanese capital.

Speaking before the latest figure was reported, Tokyo Governor Yuriko Koike had warned of a “large number” today as more positive test results followed a cluster of seven infections previously found at the office.

“Clusters in the workplace have become a big problem lately” as people have emerged from the capital’s ‘Stay Home’ initiative, she told reporters earlier.
