Why people convert Tokyo to PST time

  • Scheduling a call from Tokyo to PST: a 10:00 AM start in Tokyo lands at 5:00 PM in PST the previous day, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a -17h gap: Tokyo 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 Tokyo.
  • Coordinating a Tokyo-based team with PST 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 JST" is unambiguous; "3 PM" across a -17h gap is not.
  • With a -17h gap there is no shared 9-to-5 window, so alternate the early start: one week Tokyo takes the early slot, the next week PST does.
