Japan Time Now: Current Japan Standard Time
JST
Sunday, October 18, 2026 in Tokyo
Japan Standard Time is UTC+9 on Sunday, October 18, and it stays there all year. Only the gap to other places changes, when they switch to summer time.
Where Japan Standard Time is used
All of Japan uses Japan Standard Time (UTC+9) all year, with no daylight saving time. South Korea uses the same offset.
Good to know
Japan tried daylight saving time after the war but dropped it in the early 1950s. Tokyo is 13 hours ahead of New York in summer and 14 in winter.
Winter and summer gaps
| Compared with | In January | In July |
|---|---|---|
| New York | 14 hours ahead of New York | 13 hours ahead of New York |
| London | 9 hours ahead of London | 8 hours ahead of London |
The gap moves because Japan keeps one time all year while the others switch to summer time.
Office hours that overlap
| City | Shared hours (JST) | Length |
|---|---|---|
| New York | No overlap | – |
| London | No overlap | – |
The working day here never meets New York's and London's: a 9 AM start in New York is 10:00 PM in Tokyo.
