Time in Daily Life
In daily Japanese life, punctuality is treated as a matter of respect rather than convenience. The national rail network is famous for trains that arrive within seconds of the printed schedule, and arriving even a few minutes late to a meeting is considered discourteous. Many offices run on a standard 9:00 to 18:00 day, though overtime (zangyo) has long been part of the working culture, especially in Tokyo and Osaka.
Japan's single time zone means there is no internal jet lag when travelling between cities, which keeps business and broadcast schedules simple across the country. Television prime time, train timetables, and school bells all follow JST uniformly from Hokkaido in the north to Kyushu in the south.
Because Japan sits at UTC+9 — close to the edge of its time zone band — summer evenings stay light very late, with sunset often after 19:00 in July. The country has debated adopting daylight saving several times, most recently in the lead-up to the 2020 Tokyo Olympics, but each proposal was dropped over concerns about energy use, agriculture, and disrupted routines.
