OP: Note that you should almost certainly leave your hotel at least 3 hours before your flight, given that you don't know your way around. Work out the train schedule with the hotel when you check in; ideally you should even buy your ticket the night before.
And I wouldn't expect to see much of Tokyo with that layover timing.
I figured we'd have a pretty late night in Tokyo--maybe a meal and a walk around. Our flight out is on ANA F, we can sleep there.
What about just making our way to Narita and staying at the Hilton there and seeing the sights in Narita?
