Time Difference Between Buenos Aires and Tokyo

Tokyo is 12 hours ahead of Buenos Aires. This is among the larger time separations remote teams must navigate. Buenos Aires and Tokyo have no overlapping standard business hours. Async communication across email or messaging platforms is the practical approach for daily collaboration. Collaboration between Buenos Aires and Tokyo requires deliberate async-first workflows: detailed written handoffs, recorded walkthroughs, and well-documented task tracking so no blocker sits idle for a full half-day. Some distributed companies operating across this gap designate a rotating early riser and late-stayer to anchor a single daily overlap call. Despite the challenge, the pairing is not uncommon in global software development, where Argentina’s technical talent pool and Japan’s market access create genuine economic motivation to make it work.
