To take it from The New York Times, in Japan, napping on the job is seen as a sign of diligence—as though you’re working yourself to exhaustion. There’s even a word for it: inemuri, which roughly translates to “present while sleeping.”
Inemuri isn’t new by any means, and has in fact been around for more than 1,000 years. However, it’s usually only cool in white collar jobs; you won’t find a barista napping on the clock. Also, inemuri isn’t only limited to work. It’s common to sleep in public—in coffee shops, in stores, on trains and buses. And because it’s baked into the culture, you’re extremely unlikely to get robbed if you fall asleep in public.
