Best Meeting Times Between US and Japan Teams (2026)
8 AM Tokyo is 4 PM in Los Angeles the day before. West Coast afternoon windows, the East Coast dead zone, and why the Philippines slot is an hour off. -
Best overlap: 4:00 PM to 6:00 PM in Seoul is 8:00 AM to 10:00 AM in Lisbon.
For a call that suits both sides, look at 4:00 PM to 6:00 PM in Seoul / 8:00 AM to 10:00 AM in Lisbon. There's just 2 hours of overlap here, so don't leave meetings to chance — lock 4:00 PM in Seoul / 8:00 AM in Lisbon into the calendar. Keep an eye on the calendar — Lisbon observes daylight saving and Seoul doesn't, which nudges this window by an hour twice a year.

WorldTimeBuddy is a very good time converter. Timezoners is a shared overlap board for a team you meet with every week. An honest comparison of where each one wins. -
Slack converts timestamps automatically and shows everyone's local time, but it can't fix a bare '3 PM' typed into a channel. The settings worth changing and the habits that do the rest. -
