Recommended meeting window
There is no overlap between standard 09:00–17:00 working hours in these two cities. You will need to schedule outside normal business hours, ask one team to take an early or late call, or rotate which side accommodates the meeting time.
If you need to set a recurring meeting, anchor it on the calendar of whichever side the meeting matters more to and let the other side's invite render in their local zone. As long as both calendars store the meeting against an IANA identifier (which all modern calendar apps do by default) the meeting will follow daylight saving correctly without you needing to adjust it twice a year.
For one-off interviews, sales calls or external customer meetings, default to a slot that is firmly inside São Paulo's 10:00–16:00 working window — the deeper interior of the day reads as polite in nearly every business culture, and gives you buffer if a previous meeting overruns.

Background on these two zones
São Paulo sits in the America/Sao_Paulo IANA zone, currently at UTC-03:00. Tokyo sits in Asia/Tokyo, currently at UTC+09:00. The current difference of 12 hours ahead of reflects whichever side, if any, is currently observing daylight saving time. If one side enters or leaves daylight saving while the other does not, the gap between the two cities will shift by exactly one hour — usually for several months.
You can read more about the rules behind those transitions on the dedicated zone pages: America/Sao_Paulo and Asia/Tokyo. The daylight saving survival guide explains how to keep recurring cross-border meetings from drifting twice a year.
