Handling a -17h gap: Osaka and PST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PST is 4:00 PM in Osaka.
Keeping family and friends in sync: knowing that 8:00 PM in Osaka is 3:00 AM in PST makes it easy to avoid calling at 3 AM.
