Best overlap: 8:00 AM to 11:00 AM in Barcelona is 3:00 PM to 6:00 PM in Tokyo.
Schedule calls for 8:00 AM to 11:00 AM in Barcelona — your colleagues in Tokyo will be online from 3:00 PM to 6:00 PM. Tokyo is 7 hours ahead of Barcelona, which gives you a solid 3-hour window. Book earlier in it and neither side is rushing. Finally, Barcelona observes daylight saving and Tokyo doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
