Sleep on the plane when it's nighttime at your destination Now is a great time to make the switch. Do your best to sleep on the plane? but only when it's nighttime in Japan.

Deciding whether to sleep on a flight to Japan depends heavily on your departure city and your arrival time in local Japan Standard Time (JST). If you are flying from the US East Coast, you are often crossing 13 to 14 time zones, making jet lag a significant hurdle. The general rule for 2026 travel is to align your sleep schedule with your destination as soon as you board. If you arrive in Tokyo in the late afternoon or evening, you should try to stay awake during the flight so you are tired enough to sleep at a normal local hour. Conversely, if you arrive in the morning, sleeping on the plane is essential to avoid "crashing" by noon. To assist with this, many travelers use a combination of light-blocking eye masks, noise-canceling headphones, and melatonin. Hydration is also key, as the dry cabin air can worsen the physical symptoms of jet lag, making the transition to a new schedule even more difficult once you land at Narita or Haneda.
