Current Time in Tokyo

Quick answer: Tokyo uses Japan Standard Time (JST) · UTC+9 year-round · no daylight saving.

Tokyo runs on Japan Standard Time, which is UTC+9. Japan doesn't use daylight saving time, so the offset is the same in January as in July, and the same clock covers Osaka, Kyoto, Nagoya, Sapporo and Fukuoka under the Asia/Tokyo zone.

That makes Tokyo the fixed end of any call. When the gap to London moves between 9 hours and 8, or the gap to New York between 14 and 13, the change comes from the other side. 9:00 AM in Tokyo is 12:00 AM in January and 1:00 AM in July in London.

The date line is the part to watch. A New York evening is already Tokyo's next morning, and a Tokyo morning is the previous afternoon or evening across the Pacific. Write the date next to the time whenever one end of the call is in the Americas.

From Singapore the gap is a single hour: 9:00 AM in Singapore is 10:00 AM in Tokyo. From London you're calling into Tokyo's late afternoon, because 8:00 AM in London is 5:00 PM in January and 4:00 PM in July in Tokyo.

From the US West Coast you call Tokyo the next morning. 5:00 PM in Los Angeles is 10:00 AM the next day in January and 9:00 AM the next day in July in Tokyo, which is why a Los Angeles-Tokyo series needs both dates in the invite.
