What Time Is It in Tokyo? Current Local Time in Tokyo, Japan
Checking the time in Tokyo for a call or flight? Tokyo runs on Japan Standard Time (JST, UTC+9) with no daylight saving changes, as tracked by Japan’s National Institute of Information and Communications Technology (NICT official clock). That fixed offset means once you know your difference from Tokyo, it stays the same every day of the year.
Time Zone: Japan Standard Time (JST, UTC+9) · Daylight Saving Time: Not observed · Difference from UK (Winter): 9 hours ahead · Difference from UK (Summer BST): 8 hours ahead · Difference from US Eastern (EST): 14 hours ahead

What time is it right now in Tokyo, AM or PM?
Current local time in Tokyo
- Tokyo operates on Japan Standard Time (JST), which is always UTC+9, as confirmed by SavvyCal’s world clock for Tokyo.
- Live readings show Tokyo in a consistent AM/PM cycle — at the time of a recent check, time.is Tokyo displayed 06:39 AM on a Monday in June 2026.
- The time zone identifier
Asia/Tokyois used universally in systems and apps, per time.is JST page.
For anyone scheduling a live meeting, the safest move is to check a real-time clock. Tokyo’s fixed offset means the only variable is your own time zone’s DST status.
How to check the exact time
- The most reliable source is Japan’s official timekeeper, NICT, which publishes the precise JST at its official clock page.
- Third-party tools like time.is and SavvyCal provide easy-to-read live clocks updated every second.
- Both 12-hour (AM/PM) and 24-hour formats are available; time.is shows both by default.
Is it currently AM or PM?
- Tokyo’s time alternates between AM and PM on a standard 12-hour cycle — there is no 24-hour-only display requirement in daily use.
- At any given moment, a live clock such as time.is Tokyo will clearly label AM or PM alongside the 24-hour reading.
- Because Japan does not observe DST, the AM/PM pattern never shifts relative to the sun the way it does in countries with clock changes.
A traveler landing in Tokyo from a DST-observing country doesn’t need to track seasonal offset shifts. The AM/PM rhythm is the same in January and July — rare for a major economic hub.
The implication: once you confirm the current time via a live source, you never have to recalibrate for a seasonal switch. Tokyo’s clock is a constant.
How many hours ahead is Japan than Ireland?
Time difference between Japan and Ireland
- Japan is 9 hours ahead of Ireland during Irish winter (GMT, UTC+0) and 8 hours ahead during Irish summer (IST, UTC+1).
- Ireland observes Irish Standard Time (IST, UTC+1) from the last Sunday in March to the last Sunday in October, as documented by Savvy Time.
- Because Japan does not shift, the Tokyo-Ireland gap changes twice a year — entirely driven by Ireland’s clock changes.
Effect of Irish Summer Time (IST)
- When Ireland switches to IST (UTC+1), Tokyo’s lead narrows to 8 hours.
- This affects call scheduling: during Irish summer, a 9 AM meeting in Dublin is 5 PM in Tokyo (vs. 6 PM in winter).
- The WorldTimeServer JST reference confirms JST as UTC+9, making the calculation straightforward: Dublin time + offset = Tokyo time.
Practical examples: call scheduling
- Winter (Dublin at GMT): 10:00 AM in Ireland → 7:00 PM in Tokyo. Good for a late-afternoon catch-up.
- Summer (Dublin at IST): 10:00 AM in Ireland → 6:00 PM in Tokyo. Calls land slightly earlier in Tokyo’s evening.
- For a reliable live conversion, use time.is Tokyo and compare with Dublin’s current offset.
The trade-off: Irish callers get a narrower overlap window in summer. Tokyo-based teams should expect meetings to shift one hour earlier relative to their evening, twice a year.
Is Tokyo 8 or 9 hours ahead of the UK?
UK time zones: GMT and BST
- The UK uses Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) from March to October.
- Wikipedia’s Japan Standard Time entry confirms JST is UTC+9, so the UK-Japan gap alternates between 8 and 9 hours.
- Clocks in the UK spring forward in late March and fall back in late October, creating two distinct offset periods.
Tokyo to UK offset calculation
- UK winter (GMT, UTC+0): Tokyo is 9 hours ahead. Example: 12:00 PM in London → 9:00 PM in Tokyo.
- UK summer (BST, UTC+1): Tokyo is 8 hours ahead. Example: 12:00 PM in London → 8:00 PM in Tokyo.
- The NICT clock provides the official JST reference against which UK callers can calculate their local offset.
Why there is a one-hour change
- The shift is entirely due to UK clocks, not Japan’s. Japan has not observed DST since 1951, per time.is Tokyo.
- During World War II, what was then called Tokyo Standard Time was used for military coordination, but the post-war period saw Japan abandon seasonal clock changes, as noted in Wikipedia’s historical account.
- Business travelers and remote workers need to remember: the UK changes, Tokyo doesn’t.
Every March and October, UK-based teams forget that the Tokyo offset shifts by an hour. A recurring calendar invite set to 9 AM London time will be wrong for two weeks until someone updates it.
Why this matters: for anyone scheduling recurring calls between the UK and Japan, the offset is reliable only if you know which UK season you’re in. Mark your calendar for the last Sunday of March and October.
Four major cities, four distinct offset patterns from Tokyo — one constant: Tokyo never changes its clock.
| City | Time Difference from Tokyo | DST Observed? |
|---|---|---|
| London, UK | 8–9 hours behind (varies by season) | Yes (BST / GMT) |
| New York, USA | 14 hours behind (EDT) / 13 hours behind (EST) | Yes |
| Sydney, Australia | 1 hour behind (AEDT) / 0 hours (AEST) | Yes |
| Mumbai, India | 3.5 hours behind (IST) | No |
What we know and what remains uncertain
Confirmed facts
- Tokyo is in JST (UTC+9) year-round, verified by SavvyCal and NICT.
- Japan has no active daylight saving time — DST was last used in 1951, per time.is.
- UK time difference varies between 8 and 9 hours due to BST (Wikipedia).
- JST is equivalent to Korean Standard Time, Eastern Indonesia Standard Time, and Yakutsk Time (Wikipedia comparison).
What’s unclear
- Exact second-by-second time cannot be provided in a static article — always refer to a live clock such as time.is Tokyo.
- Historical time zone changes before 1886 (the year JST was formalized) are not covered in standard references.
- Whether Japan will ever reintroduce DST — no serious legislative proposal currently exists, but business lobbies occasionally revive the idea.
- Whether JST’s equivalence to other time zones (e.g., Korean Standard Time) remains accurate given potential future changes in those zones.
The pattern: Tokyo’s time zone is one of the most stable in the world, but live checks are essential for certainty.
Quotes from experts
“Tokyo is in Japan Standard Time (JST), which is 9 hours ahead of Coordinated Universal Time (UTC+9). It does not observe daylight saving time.”
— SavvyCal Time World Clock, a widely used time-zone reference tool
“Japan Standard Time was established by decree in 1886, and daylight saving was briefly used during the Allied occupation after WWII.”
— Wikipedia – Japan Standard Time, the collaborative encyclopedia
For travelers and remote workers, Tokyo’s fixed clock is a rare advantage in a world of shifting time zones. While Dublin and London adjust twice a year, Tokyo stays at UTC+9 every single day. The practical consequence: once you memorize the offset from your home city, you never need to re-learn it. For anyone flying from Europe, the notorious “lost day” on arrival is real — but the time difference itself is the most predictable part of the trip. For the European business traveler, the choice is clear: set your recurring meeting invites with a seasonal alarm on your calendar, or learn to enjoy 8 AM calls in summer and 9 AM in winter.

Tokyo is in Japan Standard Time (JST), which is UTC+9 year-round. The IANA time zone identifier is Asia/Tokyo, confirmed by time.is JST.
Does Tokyo observe daylight saving time?
No. Japan has not observed daylight saving time since 1951, after a brief period during the Allied occupation following World War II. time.is Tokyo confirms Japan has no DST.
How many hours ahead is Tokyo from New York?
Tokyo is 14 hours ahead of New York during Eastern Standard Time (EST, UTC−5) and 13 hours ahead during Eastern Daylight Time (EDT, UTC−4). Since Japan does not observe DST, the difference shifts based on New York’s clock changes.
What time is it at Tokyo Disneyland?
Tokyo Disneyland uses the same time zone as the rest of Tokyo: JST (UTC+9). The park opens at 9:00 AM local time, subject to seasonal schedule changes. Check the official Tokyo Disney Resort website for current operating hours.
Do I lose a day when flying to Japan from the US?
Yes. Flying from the US to Japan crosses the International Date Line, so you arrive the following calendar day. For example, a flight leaving New York on Monday morning arrives in Tokyo on Tuesday afternoon. This is a function of the date line, not the time offset itself.
How do I convert Tokyo time to my local time?
Subtract 9 hours from Tokyo time if you are in UTC+0, or adjust by your own offset. For example, Tokyo at 3:00 PM is 6:00 AM in London during GMT (UTC+0) and 5:00 AM during BST (UTC+1). Use a live converter like time.is for real-time accuracy.
What is the current 24-hour time in Tokyo?
The current 24-hour time in Tokyo can be read live from NICT’s official clock or time.is Tokyo. Both display the time in hours, minutes, and seconds, with the option to view 12-hour or 24-hour format.
In short: These answers cover the most common queries about Tokyo time, but live tools are your best bet for exact current readings.
