JST vs EST: The Time Difference

Japan Standard Time (JST) is UTC+9. Eastern Standard Time (EST) is UTC-5. That makes Tokyo 14 hours ahead of New York in winter. During US daylight saving time (EDT, UTC-4), Tokyo is 13 hours ahead. Japan does not observe daylight saving time, so the difference shifts by 1 hour twice a year when the US clocks change.

Finding the Overlap for US-Japan Teams

There is essentially no overlap between standard US East Coast business hours and standard Japan business hours. The only workable windows are: early morning New York (7:00–9:00 AM EST = 9:00–11:00 PM JST) or late evening New York (8:00–10:00 PM EST = 10:00 AM–12:00 PM JST next day). Most US-Japan teams rotate who takes the off-hours call, or rely heavily on async communication.

Tips for US-Japan Remote Teams

Embrace async communication (Loom videos, detailed Slack messages) for most collaboration. Schedule the one weekly sync meeting for early morning EST / late evening JST or vice versa, and rotate who takes the inconvenient time. Record all meetings. Use a shared team calendar showing both JST and EST columns. When someone says "let's meet Tuesday," always confirm which Tuesday — a Tokyo Tuesday afternoon is a Monday evening in New York.
