Best time to call Tokyo from Adelaide

Waking hours, 8 am–10 pm on each clock, overlap 9:30 am–10 pm in Adelaide, which is 8 am–8:30 pm in Tokyo.

That’s for a call outside work: catching someone before or after their working day. For a work call, the meeting hours above fit inside both working days.
