9days in Tokyo

my husband & i coming to Tokyo this Feb. we would like to minimise our expenses. what we can do in tokyo alone ?

most foreign tourists go around Japan on their own. no need to go with a tour or get a guide. what to do in Tokyo?
your question is a bit too vague!..you do pretty much the same as in any other town:
walk around various neighbourhood (a train goes in a loop around most of Tokyo's downtown neighbourhood. you will need a day pass)
in each neighbourhood look at buildings of any kind, check small stores and big department stores, visit temples, shrines and parks.. for precise details about all the Tokyo's neighbourhoods, special sights etc. you need to do some homework on this site (check at the top of this page TRAVEL, Japan A-Z, and read all the previous questions about trips to Tokyo--there must hundreds of them--you also need to check actual guidebooks (lonely Planet for exemple)and also internet hotel sites like www.japanhotel.net to give you an idea about accomodations.

Buy a couple of travel guides, use this website, and something that work well for me was Youtube.

I would walk around Tokyo and be very familiar just because of Youtube.
