Open Meeting Planner →London and Tokyo share finance as core industries, which is where the traffic between them comes from. Tokyo runs 9 hours ahead of London, far enough that the morning in one is already the next day in the other.
Both cities work Monday to Friday, London typically 09:00–17:30 and Tokyo 09:00–18:00 local time. On the London side the dates that break a schedule are Christmas Day and Boxing Day (25–26 December) and Easter Monday (March or April); on the Tokyo side, Golden Week (29 April to 5 May) and Obon (around 13–16 August).
There is no hour when both offices are open, only the edges: an early start in London meets a late finish in Tokyo. Alternate who stretches, and keep those calls short. Only London changes its clocks, so the gap shifts by an hour twice a year while Tokyo stays put.
Tokyo is 9 hours ahead of London. The gap changes by an hour around the clock changes.
There is no hour when both offices are open. The closest is early morning in London against the end of the day in Tokyo; alternate which side takes the awkward slot.
Alternate. A standing call that is always 07:00 for London or always 19:00 for Tokyo is resented within a month; rotating it keeps both sides in the room.
Not always. At 09:00 in London it is already the next calendar day in Tokyo, so every invitation should carry the date in both cities.
