If you are scheduling a call between Osaka and Johannesburg, the overlap window is limited to typical business hours. When it is 4 pm in Osaka it is 9 am in Johannesburg — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Osaka (10 am in Johannesburg). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Osaka and Johannesburg takes a little planning. Osaka is 7 hours ahead of Johannesburg, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Osaka — around 7 pm — which puts Johannesburg at 12 pm. Someone will need to stretch a little, but at least no one's setting a middle-of-the-night alarm. Weekends tend to give the most flexibility if you can agree on a time in advance.
