A 9:00 start in Paris means a 17:00 meeting in Yokohama during winter, and a 16:00 meeting in summer. That single hour is the only moving part. Japan stays on Japan Standard Time all year. Paris shifts between Central European Time (UTC+1) and Central European Summer Time (UTC+2). The gap shrinks in late March, widens in late October.
Current Time Difference: 7 or 8 Hours?
| Period | Paris Time Zone | Yokohama Time Zone | Time Difference |
|---|---|---|---|
| Late October to late March | Central European Time (CET, UTC+1) | Japan Standard Time (JST, UTC+9) | Yokohama is 8 hours ahead |
| Late March to late October | Central European Summer Time (CEST, UTC+2) | Japan Standard Time (JST, UTC+9) | Yokohama is 7 hours ahead |
Yokohama never changes its clocks. Japan abolished daylight saving time in 1952 and has not reinstated it. When Paris moves to CEST in spring, the gap shrinks by one hour. When Paris returns to CET in autumn, the gap widens again.
When Does the 7 or 8 Hour Gap Apply?
The 8-hour gap holds from the last Sunday of October until the last Sunday of March. The 7-hour gap runs from the last Sunday of March until the last Sunday of October. The exact dates shift each year. In the week around each change, double-check: Paris adjusts on a Sunday at 02:00 local time, while Yokohama carries no such event.
What Is the Best Overlap for Yokohama vs Paris Calls?
The reliable daily overlap sits at:
8:00-10:00 CET = 16:00-18:00 JST
That is the start of the Paris working day and late afternoon in Yokohama. Both sides are awake and at their desks.
When Paris is on CEST, the same clock time in Paris maps one hour earlier in Yokohama:
8:00-10:00 CEST = 15:00-17:00 JST
The window still works. A 9:00 meeting in Paris becomes 17:00 in Yokohama in winter, 16:00 in summer.
A 9:00 start in Yokohama is 1:00 in Paris on CET or 2:00 on CEST. Too early. A 17:00 meeting in Yokohama is 9:00 in Paris on CET or 10:00 on CEST. That is the sweet spot.
Travel Time and Jet Lag
Flying from Paris to Yokohama means heading east. You lose time. A direct flight from Paris Charles de Gaulle to Tokyo Narita takes about 12 to 13 hours. You arrive the next day, typically in the afternoon.
The 7 or8 hour difference is manageable. Shift your sleep schedule a few days before departure. A more practical move: on arrival in Yokohama, get morning sunlight. On the June solstice, sunrise is at04:26. On the December solstice, it is at06:46. Expose yourself to that light as soon as you can. It resets your internal clock faster than anything else.
Flying from Yokohama to Paris is westbound. You gain time. Leave in the evening and arrive in Paris the same morning. Jet lag is usually milder going this direction. Expect to feel tired early in the evening for a few days.
Yokohama vs Paris Time: What to Do Next
For a recurring meeting, lock in 9:00-10:00 CET / 16:00-17:00 JST during winter, and 9:00-10:00 CEST / 16:00-17:00 JST during summer. That single slot works year-round if you remember the European clock change.
