What to do in Japan without very much money?

I will go to Japan for two weeks at the end of Feb 2008. I am planning to fly in to Osaka and stay with a friend for a few days and after that I don't know what to do. I know I want to get to Tokyo for the last 3-4 days. I am not very picky and I don't need to stay at any expensive hotels. Actually I could even sleep in a cardboard box if I had to but I want to see as much as I possibly can. Any suggestions?

Expectant mothers who may be having multiples?

I had a single and twins....with my single I had postpartum but with my twins I didn't. My twins are all natural miracles. The were big and health 7lb 2oz and 6lb 10oz. We were scared that the boy twin might have problems but he is fine. The girl twin is just like her eldest brother. But to throw such negativity into the face of moms to be is cruel and nasty they have enough worries to deal with right now. Did they mention in your little report that parents of multiples might be getting less sleep than singles. I got less sleep because I had more than one to take care of. So unless you think you are better than anyone else get off your high horse and grow up. You would have the same problem if you were not a twin did you think of that. Maybe it is your attitude towards life that is your problem. Just realize that life is not fair and never will be it just is and we all must work very hard to make it a better place.
