Recently, I have read the book, called "Tokyo Has No Legs" Actually, the book is in Thai. It is so inspiring. The guy traveled to Tokyo with his friend with the money only US$900 (air tickets included)and stayed there for 9 days. Can you believe that??? Anyway, they have to sleep by the streets. Anyway, the experience they get is something you cannot find by just reading travel guide books. Tokyo or anywhere else have no legs. They cannot walk or visit you. If you want to have your own Tokyo experience you need to go there and experience it yourself.
