When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Japan Standard Time and Coordinated Universal Time don't overlap on the same weekday. Coordinated Universal Time is 9 hours behind Japan Standard Time.

With some flexibility, there’s a workable window outside standard hours:

  • 4 PM–8 PM in Japan Standard Time (7 AM–11 AM in Coordinated Universal Time) — suggest 6:00 PM Japan Standard Time (9:00 AM Coordinated Universal 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.
