JST vs PST/PDT: how the gap changes

The table below shows the difference through the year. Yokohama is the fixed reference.

Los Angeles time zone	Offset from UTC	Time difference from Yokohama
Pacific Standard Time (PST)	UTC-8	Yokohama 17 hours ahead
Pacific Daylight Time (PDT)	UTC-7	Yokohama 16 hours ahead

When does the switch happen in 2026? - Los Angeles enters PDT on 8 March 2026 (clocks spring forward). - Los Angeles returns to PST on 1 November 2026 (clocks fall back).

During those changeover weekends, the difference shifts by one hour overnight for one day, then stabilises.

Best overlap hours for calls and meetings

The practical problem: when it's a reasonable hour in Los Angeles, it's the middle of the night in Yokohama.

Overlap window: roughly 7:00-9:00 Los Angeles time equals 23:00-1:00 JST. That is a very narrow window, and it falls past midnight in Japan.

For a live meeting, one side makes a sacrifice:

From Los Angeles: a 7:00 or 8:00 AM call works for you. Your Yokohama counterpart joins at 11:00 PM or midnight.
From Yokohama: a 9:00 AM start means Los Angeles dials in at 4:00 or 5:00 PM the previous day (depending on PDT/PST).

Who should adjust? In practice, the Asian side often accommodates the American schedule. Many Yokohama-based teams are used to late-evening calls with the US West Coast. If you are in Los Angeles scheduling a recurring meeting, aim for 7:00-8:00 AM Pacific. Confirm with your Yokohama contact whether they prefer that or an earlier slot. The best calling window from the US West Coast runs 16:00-18:00 PST, which is 9:00-11:00 JST the next day.

Travel time and jet lag tips

The literal clock difference is 16-17 hours. The travel experience is more disorienting.

Los Angeles to Yokohama (eastbound): you lose a day. A morning departure from LA arrives in Japan the next evening. Your body clock must jump forward 16-17 hours.
Yokohama to Los Angeles (westbound): you gain a day. You leave Japan in the evening and arrive in LA the same afternoon. The time difference works in your favour, but the return trip is the harder adjustment.

Jet lag strategy for the LA, Yokohama direction: - On the flight, shift your watch to JST immediately. - Try to sleep during the flight's night hours (Japan time). - Upon arrival in Yokohama, get morning sunlight as soon as possible. Sunrise on the June solstice is 04:26; on the December solstice it is 06:46. - Avoid long naps the first afternoon. They delay your body's reset.

Narita or Haneda to Yokohama takes about 90 minutes by limousine bus or train. The last trains depart around 23:00.
