Major Japanese electronics maker Hitachi has been quick to respond to government calls to get more people working from home.
The move comes after a new state of emergency was put in place on Friday for Tokyo and its surrounding prefectures to contain surging coronavirus infections.
Only a few employees were seen at Hitachi's office in central Tokyo on Friday.
About 30 percent of its workers currently go to an office. But the company targets further reducing that to 15 percent or less.
A Hitachi human resources official says the company is putting remote working into force to protect the safety and health of employees and their families.
Haseyama Kyoji also said the company is taking steps to ensure the change in work arrangements won't lower job efficiency.
