Some businesses in Tokyo are telling their employees to work only remotely for the time being from Friday, when a state of emergency for Tokyo and three neighboring prefectures takes effect.
One such company, consulting firm Link and Motivation, has around 1,000 employees based at its head office in Tokyo's Ginza district.
The company has been promoting telework since the pandemic started last year, with only about 30 percent of its employees currently working in the office.
On Thursday, the firm's personnel officials told all its employees that they will now be in principle banned from coming to the office during the state of emergency.
One employee told an NHK reporter that he welcomes the company's decision because he worries that commuting to work could put him at risk.
But he also said some of his work can be done more efficiently in person.
The company's general affairs manager, Yokoyama Hiroaki, said the firm has been actively promoting telework, but decided to have all employees work remotely only, in a stepped-up effort to prevent infection. He said he hopes the pandemic will be brought under control as soon as possible.
