Japan uses Japan Standard Time (JST), which is UTC+9. The entire country — from Hokkaido in the north to Okinawa in the south — operates on a single time zone. Japan is one of the world's major economies to have no Daylight Saving Time, making it simpler to schedule calls and track Japan's offset from other countries.
Japan last used DST during 1948–1951 under the US occupation administration. It was abolished in 1952 due to public opposition, particularly from farmers and workers who found early sunrises disrupting. Proposals to reinstate DST have resurfaced periodically but have never succeeded.
Because Japan does not change clocks, the time gap between Japan and DST-observing countries fluctuates seasonally. Japan is 14–15 hours ahead of New York and 8–9 hours ahead of London, depending on whether those countries are currently on standard or daylight time.
