HND-bound flights are the slower direction by about 60 minutes in our estimate: the route runs partly 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

JFKAmerica/New_York — UTC−4 now; UTC−5 standard time, UTC−4 during daylight saving time
HNDAsia/Tokyo — UTC+9 now; UTC+9 all year (no daylight saving time)
DifferenceTokyo is 13 hours ahead of New York today; +14 h in January and +13 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying JFK → HND. The clock change is 13 hours, but to your body that is a shift of 11 hours the other way. Your body clock has to move 11 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 11 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.
