DST and UTC details
Tokyo normally stays on UTC+09:00 all year because Japan does not currently apply daylight saving time. That stability makes Tokyo easier to reason about than cities that shift between winter and summer offsets, but the international comparisons still change when London or New York move their clocks.
Best hours for international calls
With London
16:00 to 18:00 in Tokyo overlaps with 08:00 to 10:00 in London. Earlier Tokyo slots are even better for the UK side.
With New York
20:00 to 22:00 in Tokyo overlaps with 07:00 to 09:00 in New York. This is workable for urgent coordination but not ideal for daily meetings.
With UTC-based releases
Release notes written in UTC help Tokyo teams avoid confusion when comparing output against Europe and the Americas.
FAQ
Does Tokyo use JST or UTC?
Tokyo local civil time is JST. UTC is still useful as a neutral standard when you publish global schedules.
What is the IANA zone name?
The correct IANA identifier is Asia/Tokyo.
Why can the London gap change if Tokyo does not use DST?
Because London changes its own offset during British Summer Time, which changes the relative difference.
