Hey, I'm going to Japan from the 11th-26th of January 2010.
I'm going to Nozawa Onsen for 10 days for skiing and Tokyo for 4 days.
I have been to Japan before and went to Shiga Kogen, Kyoto and Toyko however going to Tokyo was different to the rest of the trip as I did not research what to do well enough and even though being occupied and having an amazing time, I feel there was alot more I could have done.

I thought the Japan Forum would be easily the best place to ask for this and I have read some other threads in this section however they didn't exactly answer my exact queries.

1. In Tokyo, what are the best places to do, what are the best landmarks to see what districts are the best for the day, where is the best food, are there any futuristic quirky interesting museums or places to see? I want to make the most of this trip and want to see what places will be the best to go too.
Any other interesting tips or places about Tokyo will be greatly appreciated and all responses will aswell.

2. Anyone know anything about Nozawa Onsen? If so the same questions for Tokyo kind of apply.
