- Finding shared working hours: both Sydney and Tokyo are inside the 9-to-5 working day between 10:00 AM and 5:00 PM AEST time (9:00 AM–4:00 PM JST). That is roughly 7 hours of usable overlap.
- Watching a live event or market open: Sydney viewers need 8:00 AM in Tokyo to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to Sydney.
