The question is vague, but I assume it's one of these flights into Haneda that land around 10-11 pm.

In that case you should stay up during the flight (or most of it or try to sleep during the beginning) and then go to bed when you arrive and take a melatonin if you wake up too early. Ambien for adjusting sleep patterns is like using a howitzer to kill a mosquito.

I fly UA so land at NRT at 4-5 pmish, so then the struggle is to stay awake. It's obviously easier from the west coast.
