Why people convert São Paulo to Tokyo time

Scheduling a call from São Paulo to Tokyo: a 10:00 AM start in São Paulo lands at 10:00 PM in Tokyo, so you can confirm the slot without doing the arithmetic yourself.
Handling a +12h gap: São Paulo and Tokyo have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Tokyo is 9:00 PM in São Paulo.
Booking travel or deliveries: tracking Tokyo local time against São Paulo keeps pickup windows and arrival estimates honest across the +12h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a +12h gap is not.
With a +12h gap there is no shared 9-to-5 window, so alternate the early start: one week São Paulo takes the early slot, the next week Tokyo does.

About BRT (Brasilia Time)

Brasilia Time (BRT) is the standard time in the most populous regions of Brazil, including São Paulo, Rio de Janeiro, and the capital Brasília. Brazil abolished daylight saving time in 2019, so BRT is now observed year-round in these regions. Brazil spans four time zones in total.

Japan Standard Time (JST) is the standard time zone for all of Japan. Japan does not observe daylight saving time. JST is 9 hours ahead of UTC and 14 hours ahead of EST. The Tokyo Stock Exchange, the world's third largest by market capitalization, operates on JST. South Korea uses the same offset (KST) but it is a distinct time zone.

Best time to call between São Paulo and Tokyo

With a +12h offset there is no overlap inside a normal 9 AM – 5 PM day. Tokyo opens at 9:00 AM JST, which is 9:00 PM in São Paulo, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

São Paulo and Tokyo have no shared working hours because of the +12h gap. Teams need to alternate early starts or rely on asynchronous handovers.
