I posted this in the Asia forum (http://www.flyertalk.com/forum/showthread.php?t=477714) but as I get closer to my departure, I figure it is a good idea to post this here to get more local insight.

I need some advice for an overnight in December. I get in from SFO at 15:25, leaving the next day for FRA at 10:30a. That leaves me with some time to play with on a Friday night.

Any suggestions on what I could do with this time? Where to stay, go? Is it worth going into Tokyo given my early departure the next day or should I just check into an airport hotel and veg-out? If you suggest that I party the whole night, any recommendations on where to go?

Ideas, comments, suggestions, itineraries would be much appreciated.

Thanks.
