Los Angeles vs Tokyo Time Difference
Los Angeles and Tokyo sit 16 to 17 hours apart — close enough to a full day that Tokyo is almost always on tomorrow's date while Los Angeles is still on today's.

Calculating the live gap…
The pairing with no overlap at all
Most city pairs on this site share at least a sliver of overlapping business hours somewhere in the day. Los Angeles and Tokyo don't. At 16 to 17 hours apart, Tokyo's entire 9-to-5 workday falls squarely in the middle of the Los Angeles night, and Los Angeles' workday falls in the middle of Tokyo's night. There's no version of "let's grab a 2 p.m. call" that works for both sides — someone is always taking the meeting well outside standard hours.
Almost always a day apart
Because the gap is closer to a full day than to half a day, Los Angeles and Tokyo are usually not just hours apart but a full calendar date apart. A Friday afternoon in LA is already Saturday morning in Tokyo, which matters for anything date-sensitive — contract deadlines, product launch timestamps, or "same-day" service agreements that quietly become next-day depending on which city's clock is being used.
Why Hollywood and Tokyo keep talking anyway
Despite the scheduling headache, Los Angeles and Tokyo are two of the most important hubs on the planet for film, television, anime, and video games. Japanese anime studios routinely license work to US streaming platforms headquartered in LA; American game publishers coordinate console releases with Japanese hardware makers and developers. Neither side gets a convenient overlap window, so cross-Pacific entertainment deals are built around asynchronous handoffs — documents and notes passed at the end of one city's day for the other to pick up at the start of its own.
Best time to call, hour by hour
The table below runs through a full Los Angeles day and shows the matching Tokyo time for each hour. Because the gap is so large, no row falls inside a shared 9:00-to-17:00 workday for both cities.

There is no highlighted row above — this is the one pairing on WatchTime Online with zero standard-hours overlap. Teams bridging LA and Tokyo typically pick either an LA early morning or a Tokyo early morning as the least-disruptive compromise.
How we calculate this page: both live clocks, the current gap, the DST transition dates, and the hour-by-hour overlap table are all computed directly from the IANA America/Los_Angeles and Asia/Tokyo time zone data via your browser on every page load — nothing here is a fixed, hard-coded figure.
Frequently asked questions
What is the time difference between Los Angeles and Tokyo?
Sixteen hours during Los Angeles' summer (Pacific Daylight Time) and seventeen hours during its winter (Pacific Standard Time), with Tokyo ahead. Because the gap is so large, Tokyo is almost always a full calendar day ahead of Los Angeles.
Is Tokyo always a day ahead of Los Angeles?
Nearly always. Since Tokyo is 16 to 17 hours ahead, a clock reading in Los Angeles corresponds to the same time the following day in Tokyo for most of the 24-hour cycle — a 9:00 a.m. Monday call in LA lands at 1:00 or 2:00 a.m. Tuesday in Tokyo.
Is there any normal-business-hours overlap between Los Angeles and Tokyo?
No. Tokyo's 9:00-to-17:00 workday falls entirely within Los Angeles' overnight hours, and vice versa, so there is no stretch of the day when both cities are simultaneously in a typical office day. Teams that work across this pairing generally settle for an early-morning call on one side or a late-evening call on the other.
Why does this pairing matter for entertainment and tech companies?
Los Angeles and Tokyo are two of the world's largest hubs for gaming, animation, and film licensing, and business between them — a Hollywood studio negotiating a Japanese distribution deal, or a US game studio coordinating with a Japanese publisher — routinely has to work around a gap with effectively zero shared daytime hours.
Does Tokyo observe daylight saving time?
No. Japan Standard Time has held at a fixed UTC+9 since 1886, except for a brief experiment from 1948 to 1951. Los Angeles is the only side of this pairing whose clock ever moves.
How do I convert Los Angeles time to Tokyo time?
Add 16 hours (during Pacific Daylight Time) or 17 hours (during Pacific Standard Time), then adjust the calendar date forward by one day in most cases. For a guaranteed-accurate conversion on any specific date, use the time zone converter on WatchTime Online.
