What is UTC in JST?

Japan Standard Time is 9 hours ahead

Coordinated Universal Time is on UTC+0:00 and Japan Standard Time is on UTC+9:00 right now. That gap holds all year, because neither zone observes daylight saving.

Scheduling between the two

There is no overlap between a nine-to-six working day in the prime meridian and one in Tokyo — the gap is too wide. A call has to sit early or late for one side. Early morning in the prime meridian is the usual compromise, since that is late afternoon or evening in Tokyo.

Coordinated Universal Time (UTC) is used in aviation, computing, and science worldwide. UTC never changes for daylight saving.
