Notorious for a hardworking culture, Japan launched an initiative to help people cut back. But three years into the effort, the country is having a hard time coaxing people to take a four-day workweek.

Japanese lawmakers first proposed a shorter work week in 2021. The guidelines aimed to encourage staff retention and cut the number of workers falling ill or dying from overwork in an economy already suffering from a huge labor shortage. The guidelines also included overtime limits and paid annual leave.

However, the initiative has had a slow start: According to the Ministry of Health, Labor, and Welfare, only about 8% of companies in Japan allow employees to take three or more days off a week.

It’s not just companies — employees are hesitant, too.

Electronics manufacturer Panasonic, one of Japan’s largest companies, opted into the effort in early 2022. Over two years in, only 150 of its 63,000 eligible employees have chosen to take up four-day schedules, a representative of the company told the Associated Press.

Other major companies to introduce a four-day workweek include Uniqlo parent Fast Retailing, electronics giant Hitachi, and financial firm Mizuho. About 85% of employers report giving workers the usual two days off a week.

Much of the reluctance to take an extra day off boils down to a culture of workers putting companies before themselves, including pressure to appear like team players and hard workers. This intense culture stems from Japan’s postwar era, where, in an effort to boost the economy, then-Prime Minister Shigeru Yoshida enlisted major corporations to offer their employees lifelong job security, asking only that workers repay them with loyalty.
