Best meeting times between Chicago and Tokyo

When coordinating remote teams or scheduling client meetings across Chicago (United States) and Tokyo (Japan), overlapping business hours depend on the 15-hour offset.

• Chicago working window: 9:00 - 17:00 (CST/CDT)

• Tokyo working window: 9:00 - 18:00 (JST)

• No direct 9-to-5 standard business overlap; morning/evening flex hours recommended

Tips for multi-timezone collaboration

  • Asynchronous Updates: Rely on recorded walkthroughs and documented PRs for handoffs when offset exceeds 6 hours.
  • Shared Calendars: Configure secondary timezone displays in Google Calendar or Outlook to prevent accidental off-hours invitations.
  • Rotated Call Times: For regular cross-regional standups, alternate weekly meeting times so no single hub constantly sacrifices personal evenings.
