History
How Japan keeps time.
Japan adopted its current standard time on January 1, 1888 (Meiji 21), choosing UTC+09:00 to align with its geographic position. This unified the country under one time zone for the first time, replacing the old local solar time system. Japan briefly observed daylight saving time from 1948 to 1951 during the post-war period under Allied occupation, but it was unpopular and discontinued. Despite occasional debates about reintroducing DST to save energy, especially after the 2011 energy crisis, DST has never been permanently reimplemented.
Did you know?
Things about Japan's time.
Despite spanning a large geographic area from north to south, Japan maintains just one time zone, meaning sunrise and sunset times vary significantly across the country. Hokkaido, for example, sees much earlier sunrises and sunsets compared to southern islands like Okinawa. The country's consistent use of JST (UTC+09:00) simplifies coordination across regions and reduces scheduling complexity for national events like the widely watched annual 'Kōhaku Uta Gassen' broadcast, which airs on New Year's Eve at the same clock time across the country.
