American workers are notoriously under-rested, and in many cases, workers wear their sleep deprivation as a badge of honor.
Japanese workers are known for working long hours— in fact, there is a word for "death by overwork" — and offices have adopted a habit that would be forbidden in most American offices: sleeping on the job.
In Japn, napping in the office is not only common, but can be seen as a sign of employee diligence. The word for the practice is "inemuri," or "sleeping on duty," and is most prevalent among senior employees, according to The New York Times.
The biggest rule of inemuri is to respect other people's boundaries while you sleep.
It would be considered disruptive "if you stretched out under the table in the office conference room, or took up several spaces on the train, or laid out on a park bench,” Harvard social anthropology professor Theodore Bestor told The Times.
