Tokyo to London time
London is 9 hours behind Tokyo. Tokyo uses Asia/Tokyo (UTC+9); London uses Europe/London (UTC±0).
When the time difference changes
The two places don't switch daylight saving time on the same days, so the gap shifts during the year:
- Sun, Mar 28, 2027: London springs forward an hour. Then London is 8 hours behind Tokyo.
Best times to meet
Working hours (9 AM to 5 PM) don't overlap today. The best compromise times are below.
- 1 4:00 PM in Tokyo = 7:00 AM in London
- 2 6:00 PM in Tokyo = 9:00 AM in London
- 3 7:00 PM in Tokyo = 10:00 AM in London
Jet lag and travel: Tokyo to London
Your body clock shifts 9 hours later (westward, the easier direction). Expect about 6 days to adjust at CDC average rates (1 h/day east, 1.5 h/day west).
- Before you fly: bed 1 hour later for 2–3 nights.
- On arrival: eat, sleep and get daylight on London time.
- Trips of 2 days or less: consider staying on Tokyo time.
