A calendar invite lands from a Nagoya supplier: 09:00 JST, 12 March. Your phone says you are 14 hours behind. But wait: New York springs forward on 8 March. So is the gap 14 hours or 13? Here is the answer, and every other time fact that matters for Nagoya.
What Time Is It in Nagoya Right Now?
Nagoya runs on Japan Standard Time (JST), which is UTC+9 year-round. The current local time is the same as Tokyo, Osaka, and every other city in Japan. There are no regional time zones. If your device shows “Asia/Tokyo,” that is the correct setting for Nagoya.
Does Nagoya Observe Daylight Saving Time?
No. Japan abolished daylight saving time in 1952 and has not reinstated it. The clocks in Nagoya never change. The offset stays UTC+9 through summer and winter.
This catches many visitors. In March, when New York and London spring forward, Nagoya does not move. In October, when they fall back, Nagoya stays put. The time difference between Nagoya and those cities shifts entirely because they change, not Nagoya.
For the full history, see daylight saving time in Nagoya.
What Time Zone Is Nagoya In?
Nagoya is in the IANA time zone Asia/Tokyo. This zone applies to all of Japan’s main islands. The standard abbreviation is JST (Japan Standard Time).
The official timekeeper is the National Institute of Information and Communications Technology (NICT), which maintains Japan’s atomic clocks and broadcasts JST via NTP servers and the JJY radio time signal.
For technical details, see the Nagoya time zone page.
Is Nagoya the Same Time as Tokyo?
Yes. Identical. Nagoya and Tokyo share the exact same clock time. Japan uses a single time zone, so despite Nagoya sitting at 136.9°E, roughly 1.9 degrees east of the standard meridian at 135°E, the clock does not adjust. Solar noon in Nagoya occurs at about 11:48 JST, a few minutes later than Tokyo’s solar noon, but the wall clock reads 12:00.
What Is the Time Difference Between Nagoya and London/New York/Sydney?
The difference depends on whether the other city is observing daylight saving time. The table below shows the gap on two reference dates: 15 January 2026 (winter in the northern hemisphere) and 15 July 2026 (summer).
| City | Offset from Nagoya (January) | Offset from Nagoya (July) |
|---|---|---|
| London | 9 hours behind | 8 hours behind |
| New York | 14 hours behind | 13 hours behind |
| Los Angeles | 17 hours behind | 16 hours behind |
| Paris | 8 hours behind | 7 hours behind |
| Dubai | 5 hours behind | 5 hours behind |
| Mumbai | 3.5 hours behind | 3.5 hours behind |
| Singapore | 1 hour behind | 1 hour behind |
| Sydney | 2 hours ahead | 1 hour ahead |
| São Paulo | 12 hours behind | 12 hours behind |
Key rule: Nagoya does not change. The other city’s DST transition is what moves the gap.

Does Japan Use 24-Hour Time?
Both. Japan uses 12-hour and 24-hour notation interchangeably. Train timetables, Shinkansen schedules, and digital displays use 24-hour format (e.g., 23:45, 00:15). Shops, casual writing, and conversation use 12-hour with AM/PM or the Japanese prefixes 午前 (gozen, morning) and 午後 (gogo, afternoon).
If you see “00:00” on a train timetable, that is midnight, not noon. If you see “12:00,” it is noon. The 24-hour time in Nagoya guide explains how to read schedules without confusion.
What Is the IANA Time Zone for Nagoya?
Asia/Tokyo. There is no IANA zone called “Asia/Nagoya” or “Asia/Osaka.” Asia/Tokyo is the single zone for all of Japan. Use it in your device’s world clock, your calendar app, and your code.
