Remember this is F.

SFO-NRT
The tried and true technique is...
1) Enjoy the service then...
2) Sleep for a few hours if you can.
3) Go out for dinner/drinks
4) Bed at Midnight.
5) Usually up at 6-7 (That's a normal nights sleep.)

NRT-SFO (For best results)
1) SLEEP AS MUCH AS POSSIBLE!!! You will be returning to a "Full Day" as opposed to "a night out to dinner".
2) I tend to "Enjoy the Service" on the return as well but it's ANA as opposed to err...a US carrier for instance.
