Jet Lag from Tokyo to Los Angeles

Los Angeles runs 16 hours behind Tokyo — a westbound shift over a roughly 10.5-hour flight. Expect about 11 days to feel close to normal in Los Angeles.

What to expect

Westward shifts extend the day and align with the natural drift of the circadian rhythm, so most travelers find them easier than eastward shifts.

Adjustment playbook

• Stay up later than usual the night before.
• Stay awake on the plane during Los Angeles daytime.
• Get bright late-afternoon light on arrival; avoid bright morning light day one.
• Late-afternoon caffeine is fine.
