Why people convert Lagos to Osaka time

Scheduling a call from Lagos to Osaka: a 10:00 AM start in Lagos lands at 6:00 PM in Osaka, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h gap: Lagos and Osaka 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 Osaka is 5:00 PM in Lagos.
Watching a live event or market open: Lagos viewers need 5:00 PM in Osaka to catch a 9:00 AM start there, and 4:00 PM if the event is anchored to Lagos.

Always state the zone abbreviation, not just the hour. "3:00 PM WAT" is unambiguous; "3 PM" across a +8h gap is not.
With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week Lagos takes the early slot, the next week Osaka does.
