Time difference between Tokyo and Los Angeles

Los Angeles is 16 hours behind Tokyo

Tokyo, Japan is UTC+9 · Los Angeles, the United States is UTC−8 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Tokyo does not change its clocks and Los Angeles goes forward on the second Sunday in March and back on the first Sunday in November.

Tokyo stays put all year while Los Angeles moves, so the gap changes twice a year from Los Angeles's side alone. A recurring meeting set in Tokyo's calendar will drift by an hour without anyone touching it.

When they can both be at their desks

Nine-to-five in Tokyo and nine-to-five in Los Angeles do not overlap at all. With 16 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
