If you are scheduling a call between Osaka and Chicago, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Scheduling a family call between Osaka and Chicago takes a little planning. Osaka is 14 hours ahead of Chicago, 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 Chicago at 5 am. 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.
