NRT-bound flights are the slower direction by about 115 minutes in our estimate: the route runs mostly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.

Time zones and jet lag

LAXAmerica/Los_Angeles — UTC−7 now; UTC−8 standard time, UTC−7 during daylight saving time
NRTAsia/Tokyo — UTC+9 now; UTC+9 all year (no daylight saving time)
DifferenceTokyo is 16 hours ahead of Los Angeles today; +17 h in January and +16 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying LAX → NRT. The clock change is 16 hours, but to your body that is a shift of 8 hours the other way. Your body clock has to move 8 hours later, like a westward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 8 days to fully adjust. Shifting later (as here) is usually the easier direction; evening daylight at the destination helps. Flying the other way, the shift is reversed.
