Best Meeting Time: Sydney to Tokyo
🕐 Live Timezone Overlap: Sydney & Tokyo
Sydney and Tokyo sit just one hour apart, which makes this one of the more comfortable cross-border pairings in the Asia-Pacific region. Tokyo is one hour behind Sydney, so a 10am call in Sydney lands at 9am in Tokyo: a clean, professional start for both sides. The main scheduling consideration is Sydney's daylight saving time. When Sydney shifts clocks forward in October, that one-hour gap temporarily disappears, and the two cities briefly share the same UTC offset.
Time Difference: Sydney and Tokyo
Tokyo is currently 1 hour behind Sydney. The live offsets are Sydney UTC+10 and Tokyo UTC+9. Sydney observes daylight saving and Tokyo does not, so the offset shifts twice a year if both sides aren't already aligned.
Tokyo runs UTC+9 year-round. Japan does not observe DST. Sydney runs UTC+10 under AEST for most of the year, shifting to UTC+11 (AEDT) during southern-hemisphere summer, from the first Sunday in October to the first Sunday in April. In standard time the gap between Sydney and Tokyo is one hour. Once Sydney moves to AEDT (UTC+11), the gap widens to two hours, with Sydney running further ahead of Tokyo than it does for the rest of the year.
Best Times to Meet
Both cities share an 8-hour overlap window: 10am to 6pm in Sydney maps to 9am to 5pm in Tokyo. That is a generous window. Inside that 8-hour window, the cleanest slot is typically 10am to 3pm Sydney time (9am to 2pm Tokyo time). Tokyo working days start strictly at 9am, so early slots suit Tokyo teams well. One caveat: Friday afternoon meetings are rarely welcomed by Tokyo partners for international calls, so aim for Monday to Thursday wherever possible.

Tips for Scheduling Across Sydney and Tokyo
- When Sydney is on AEDT (October to April), the gap widens to two hours: update recurring invites accordingly.
- Avoid booking Tokyo partners on any Friday after 5pm local time; those slots are rarely accepted for international meetings.
- Block out Tokyo's Golden Week (29 April to 5 May) in your calendar: most Tokyo offices close for four to five days.
- Sydney goes quiet between Christmas and 26 January; always confirm attendance before scheduling Tokyo calls into that period.
- A 10am to 3pm Sydney slot gives you a clean five-hour window that suits a 9am to 2pm Tokyo start without running late.
Public Holidays and Working Weeks
Both cities follow a standard Monday to Friday working week, 9am to 6pm. Cross-city meetings need to account for both holiday calendars. Tokyo's Golden Week (29 April to 5 May) sees most offices close for four to five days. Sydney has Australia Day on 26 January and ANZAC Day on 25 April as key dates. Additionally, Sydney offices run on skeleton staff between Christmas and Australia Day, so scheduling into that window from Tokyo requires early confirmation.
