Best Meeting Time: Tokyo to Sydney
🕐 Live Timezone Overlap: Tokyo & Sydney
Tokyo and Sydney sit just one hour apart, which makes scheduling between them unusually straightforward by Asia-Pacific standards. Sydney leads by that single hour year-round in standard time. The practical catch is that Sydney observes daylight saving time and Tokyo does not, so the gap shifts depending on the time of year. Both cities share a working day of 9am to 6pm, giving teams a generous window to connect without anyone starting at dawn or finishing late into the night.
Time Difference: Tokyo and Sydney
Sydney is currently 1 hour ahead of Tokyo. The live offsets are Tokyo UTC+9 and Sydney UTC+10. Tokyo does not observe daylight saving and Sydney observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Tokyo runs UTC+9 every day of the year. Japan does not observe DST, so the offset never changes. Sydney switches between AEST (UTC+10) and AEDT (UTC+11) depending on the season. Australian DST runs from the first Sunday in October to the first Sunday in April. When Sydney is on AEDT, the gap between Tokyo and Sydney widens from 1 hour to 2 hours. Outside that period, Sydney is just 1 hour ahead of Tokyo.
Best Times to Meet
The overlap between Tokyo and Sydney spans 8 hours: 9am to 5pm in Tokyo, and 10am to 6pm in Sydney. That is a rare luxury for cross-border scheduling. Inside that 8-hour window, the cleanest slot is typically 10am to 3pm Tokyo time, keeping Sydney participants well clear of end-of-day pressure. One caveat: Tokyo teams start strictly at 9am, and meetings past 5pm on a Friday are uncommon for international calls. Scheduling before Friday afternoon Tokyo time avoids that friction.

Tips for Scheduling Across Tokyo and Sydney
- Tokyo never shifts for DST; always check whether Sydney is on AEST or AEDT before locking in a recurring call.
- Avoid scheduling Tokyo-Sydney calls after 5pm Tokyo time on Fridays; international meetings at that hour are rarely welcomed.
- Golden Week (29 April to 5 May) closes most Tokyo offices; Sydney counterparts should not expect availability during that block.
- Sydney offices run on skeleton staff from Christmas through to late January; plan quarterly reviews well outside that window.
- When Sydney moves to AEDT in October, the gap widens to 2 hours; shift standing meetings earlier in Tokyo to compensate.
Public Holidays and Working Weeks
Both cities follow a standard Monday-to-Friday working week, with working hours of 9am to 6pm. Tokyo's most significant holiday block is Golden Week, running 29 April to 5 May, when most offices close for four to five days. In Sydney, Christmas Day (25 December) falls in the heart of the southern-hemisphere summer holiday season, when skeleton staffing is common through to late January. Any meeting series should account for both holiday calendars to avoid empty rooms on either side.
