Does Japan Use Daylight Saving Time?
No — Japan does not change its clocks. The offset from UTC is the same every day of the year.
What Happens, and When
Japan does not observe daylight saving time. Japan Standard Time stays at UTC+9 year-round.
Your Time Differences Still Move — Just Not Because of You
Clocks in Japan never move, but plenty of time differences involving Japan do. Every one of these shifts by an hour when the country at the other end changes, and the date is theirs, not yours. This is why a standing call that has worked all year suddenly lands an hour out.
| Difference to | Changes on | Gap |
|---|---|---|
| London | Oct 25, 2026 | -8:00 → -9:00 |
| Paris | Oct 25, 2026 | -7:00 → -8:00 |
| New York | Nov 1, 2026 | -13:00 → -14:00 |
| Los Angeles | Nov 1, 2026 | -16:00 → -17:00 |
| Auckland | Apr 4, 2027 | +4:00 → +3:00 |
| Sydney | Apr 4, 2027 | +2:00 → +1:00 |
Shaded rows are within the next two months. Gaps are shown from Japan's point of view: a positive number means the other city is ahead.
Why Japan Does Not Change Its Clocks
Daylight saving was imposed during the Allied occupation and abolished in 1952, almost as soon as Japan regained the power to decide. Reintroduction has been proposed several times since, including ahead of the 2020 Olympics, and has never carried.
The practical consequence is that time differences involving Japan still move twice a year, but because the other country changed, not this one. That catches people out precisely because nothing appears to have happened locally.
To see the exact gap between any two places on any date, use the time zone converter, or the meeting planner for a whole group at once.

Frequently Asked Questions
Does Japan observe daylight saving time?
No. Clocks in Japan do not change, so the local offset from UTC is the same every day of the year.
Why does the time difference to my country still change twice a year, then?
Because the other country moves. If you are scheduling between Japan and somewhere that observes daylight saving, the gap between you shifts by an hour when their clocks change, not when yours do.
Will my meetings be affected?
Any recurring meeting booked across a clock change needs checking, because the two ends move at different times — or one end does not move at all. The time zone converter shows the exact gap for any pair on any date.
