Best time for work calls
If you are scheduling a call between Tokyo and Seoul, the overlap window is limited to typical business hours. When it is 9 am in Tokyo it is 9 am in Seoul β a workable window for scheduling. The latest reasonable overlap is around 5 pm in Tokyo (5 pm in Seoul). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Tokyo and Seoul have a comfortable window for a family call β no awkward alarms required. Tokyo and Seoul are in the same time zone, which gives you 3 hours of genuine overlap when both sides are free. Aim for between 6 pm and 9 pm in Tokyo β that lands at 6 pm to 9 pm in Seoul, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
