In the graph below you see the time zone difference between Pacific Standard Time and Japan Standard Time. Drag the bubble to adjust the time and to see the corresponding time in the other time zone.
Pacific Standard Time is the time zone of the Canadian and US West Coast, including cities like Seattle, Vancouver, San Francisco and Los Angeles. Japan Standard Time is the time zone of Japan, with places like Tokyo, Osaka, Sapporo, Nagoya and Fukuoka.
Usually it is preferable to schedule meetings in the early morning, or late evening for the person in PST and in the evening, or early morning for the person in JST.

Pacific Standard Time is the time of the Western United States and Canada and is typically abbreviated as PST. It is 8 hours behind GMT. This means that when the clock is noon in London (GMT), it is 4AM in Seattle (PST).
Most of the Western US and Canada are following Pacific Standard Time.
This can be a bit tricky as most states on the US Pacific Coast do apply daylight saving time, calling PST for PDT, or Pacific Daylight Time, instead and sets the clocks in November and March respectively.
Japan Standard Time, or JST for short, is the standard time zone of Japan. It is 9 hours ahead of UTC. This also includes the islands of Okinawa even though they previously used a separate time zone. These days all of Japan runs on Japan Standard Time, from Hokkaido to Kyushu.
Japan is the only country using Japan Standard Time. It is however the same time as KST – Korean Standard Time and AWDT – Australian Western Daylight Time (i.e. when Western Australia applies Daylight Saving Time).
All cities in Japan applies JST, including Tokyo, Kyoto, Sapporo, Fukuoka, Hiroshima, Nagano and Nagoya.
DST (Daylight Saving Time) is currently not applied in Japan, although there have been attempts to re-introduce it. Especially the northern island of Hokkaido are in favor of DST as the sun rises very early in summer under the current system. Another argument to re-introduce DST has been that it would have a positive effect on emissions, but this has not been proven in any studies yet.
