If you are scheduling a call between Ho Chi Minh City and Tokyo, the overlap window is limited to typical business hours. When it is 9 am in Ho Chi Minh City it is 11 am in Tokyo — a workable window for scheduling. The latest reasonable overlap is around 3 pm in Ho Chi Minh City (5 pm in Tokyo). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Ho Chi Minh City and Tokyo takes a little planning. Ho Chi Minh City is 2 hours behind Tokyo, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Ho Chi Minh City — around 7 pm — which puts Tokyo at 9 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.
