Many commuters and travelers in Japan sleep on trains due to a combination of long working hours, extensive daily commutes, sleep deprivation, and a deep-seated cultural sense of public security. Japanese society places heavy demands on professional and academic life, often resulting in late nights and early mornings. Because trains are remarkably quiet, smooth, and punctual, passengers feel entirely safe dozing off during transit. This widespread behavior is socially accepted as a sign of hardworking exhaustion, and sleeping passengers typically wake up precisely at their destination stop without missing their transfers.
