TOKYO -- Japanese sleep less than the inhabitants of every other developed nation, and some analyses suggest this trait hurts productivity. However, a recent survey shows Japanese are snoozing more on weeknights for the first time since 1976, when the government began keeping track.
In 2021 everyone in Japan 10 and older slept for an average of 462 minutes (seven hours and 42 minutes) per weekday. This is an increase of 13 minutes compared to the 2016 survey.
