Time difference between Anchorage and Tokyo

Tokyo is 17 hours ahead of Anchorage

Anchorage, the United States is UTC−9 · Tokyo, Japan is UTC+9 — 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 Anchorage goes forward on the second Sunday in March and back on the first Sunday in November and Tokyo does not change its clocks.

Tokyo stays put all year while Anchorage moves, so a meeting fixed in Tokyo's calendar shifts by an hour twice a year at Anchorage's end.

When they can both be at their desks

Nine-to-five in Anchorage and nine-to-five in Tokyo do not overlap at all. With 17 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.
