Current Time in Japan

Time in Japan

Japan uses JST (UTC+9) for the locations in this directory.

Japan does not currently change this zone seasonally; its UTC offset remains fixed unless the law or time-zone database is updated.

Coverage Across Japan

The directory currently includes 8 cities in Japan. Each city keeps its own coordinates and IANA time zone, so the clocks and solar calculations on the linked pages are tied to that location rather than copied from the capital.

Within this city set, Sapporo is the furthest north and Fukuoka the furthest south, a latitude span of about 9.5°. That geographic separation is why day length, dawn and sunset can differ even when the civil clock is the same.

Fukuoka and Sapporo are the east-west extremes represented here, about 10.9° of longitude apart. Longitude changes when the sun reaches local noon and the horizon, so one sunrise, sunset or prayer timetable should not be reused for every city.
