Adelaide is 30 minutes ahead of Tokyo during standard time, and 1 hour 30 minutes ahead during Adelaide's daylight saving period. When it's 12:00 PM in Adelaide, it's 11:30 AM in Tokyo (during ACST).
Adelaide uses ACST/ACDT (UTC+9:30/+10:30) and observes daylight saving time, while Tokyo uses JST (UTC+9) year-round with no DST. This creates a variable but always small time difference.
Any business hours work perfectly! The minimal 30-90 minute difference makes scheduling between these cities extremely easy. Standard 9-5 business hours in either city align well with the other.
Japan and South Australia have growing economic ties, particularly in defense, space technology, and education sectors. Adelaide hosts a significant Japanese expatriate community.
