Tokyo is so mindblowing! The train system is amazing. It is fast, on time and fully utilised. You can even check the timetable from your mobile (and that was in 2001)! There are people everywhere wearing anything. The buildings are huge! There is a huge American influence with restaurants, clothing, etc. You can get anything you want. But don't stand still in the middle of the footpath or else you will be run over by hundreds of Japanese in a hurry. Ropongi (bad spelling) is an awesome party district. Had a great night out there (all night). Shinjuku is the business district, but it still has good shopping for electronics, cosmetics and clothing (if you are of teeny tiny proportions). The public toilets in the big department stores play classical music to you while you are doing your business even!
