In Japan, public napping is a sign of hard work. It’s called ‘inemuri,’ which means ‘sleeping on duty’ or ‘sleeping while present.’ Because falling asleep in public is thought to be a symptom of working yourself to exhaustion, it’s socially acceptable in restaurants, stores, commuter trains, and on park benches- as long as you don’t sprawl out and take up too much space.
