Best Time to Call Tokyo from Seattle
🕐 Live Timezone Overlap: Tokyo & Seattle
Tokyo and Seattle sit too far apart in time for a comfortable shared working day. With Seattle 16 hours behind Tokyo, an in-hours overlap doesn't exist under a standard 9am–6pm schedule on either side. Most teams that bridge these cities lean async-first: shared docs, recorded video, and a single brief live call when a decision genuinely needs both rooms. The widget below shows the time-of-day in both cities so you can find the least painful slot.
Time Difference: Tokyo and Seattle
Seattle is currently 16 hours behind Tokyo. The live offsets are Tokyo UTC+9 and Seattle UTC-7. Tokyo does not observe daylight saving and Seattle observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Tokyo does not observe DST, and Seattle also observes DST. When either side switches, the offset shifts by an hour. The US and Europe also change clocks on different weekends, so for one week in spring and one in autumn the usual offset between US and European cities is off by an hour. Always confirm with the live tool above when you're scheduling a recurring meeting that spans a DST changeover.
Best Times to Meet
Without an in-hours overlap, the practical options are a 7am call from Tokyo or an 8pm call from Seattle, depending on which side is willing to flex. Many distributed teams rotate the inconvenience so the same person isn't always taking the early or late call. For one-off conversations, a recorded async message via Loom or a written brief is usually faster than negotiating a calendar slot.

Tips for Scheduling Across Tokyo and Seattle
- There is no in-hours overlap, so rotate between an early start in Tokyo and a late finish in Seattle on alternating weeks.
- Seattle observes daylight saving but Tokyo does not, so your offset shifts twice a year. Lock recurring meetings to local time in Tokyo.
- Check USA's public holiday calendar in advance: a few national holidays shift entire working weeks.
- Working days start strictly at 9am. Late evening presence is less expected than it once was, particularly in younger teams.
- With a 16-hour gap, default to async updates: a recorded video the night before is usually faster than a 30-minute call at 6am or 10pm.
Public Holidays and Working Weeks
Japan runs a Monday–Friday working week with Golden Week (04-29 to 05-05) and Obon (mid-August) among the key closures. USA's major holidays include a standard public holiday set. Cross-check both calendars when scheduling recurring meetings: a 30-minute call in one city's holiday week typically gets a much lower attendance rate than the same slot a week later.
