Planning the trip to Tokyo

I have not been really active blogger lately because I have been planning my trip to Tokyo. It is not an easy job I can tell you! I have spent my evenings reading different guide books and it has proved to be really difficult to choose what would be the most important sights to see there. There is so much to see and I have only 6 days in Tokyo and 4 days at Kyoto. Those of you who have visited Tokyo you are more than welcome to share your best/worst experiences with me here! Please tell me at least things that I definitely should not miss! A lot of shopping is involved anyway so I think I will not lack things to post about after this trip. The trip will take place 4-15.11. after that a lot more activity expected around here. So please be patient!
