Why people convert EST to Osaka time

Scheduling a call from EST to Osaka: a 10:00 AM start in EST lands at 12:00 AM in Osaka the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +14h gap: EST 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 11:00 PM in EST.
Coordinating a EST-based team with Osaka contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM EST" is unambiguous; "3 PM" across a +14h gap is not.
With a +14h gap there is no shared 9-to-5 window, so alternate the early start: one week EST takes the early slot, the next week Osaka does.
