In Japan, where workers sleep less, the trend of sleeping in the workplace is growing, The Irish Times reports.

It’s a daily struggle known to office workers the world over: a productive morning rewarded with a decent lunch, and then, at about 3pm, the leaden eyelids and urge to snatch 40 winks.

In Japan, where workers get less sleep on work nights than those in other countries, more and more companies are encouraging employees to sleep on the job, convinced that it leads to better work performance.

Okuta, a home renovation firm near Tokyo, allows its employees to take a 20-minute power nap at their desks or in the staff lounge. Introduced two years ago on the orders of the firm’s chairman, Isamu Okuta, it has proved a huge hit.
