When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Coordinated Universal Time and Japan Standard Time don't overlap on the same weekday. Japan Standard Time is 9 hours ahead of Coordinated Universal Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–11 AM in Coordinated Universal Time (4 PM–8 PM in Japan Standard Time) — suggest 9:00 AM Coordinated Universal Time (6:00 PM Japan Standard Time).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
