Tokyo

Tokyo is 16 hours ahead of Seattle right now.
Does the gap change?
The gap isn't fixed. Seattle changes its clocks for daylight saving time and Tokyo doesn't, so the difference moves during the year:
- From around November 2, 2026: Tokyo ahead by 17 hours
- From around March 15, 2027: Tokyo ahead by 16 hours
Best time to meet
Normal office hours in Tokyo and Seattle don't overlap. The most workable window is 3 PM to 10 PM in Seattle, which is 7 AM to 2 PM in Tokyo, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
