I'm not in a band or anything like that, but I would love to go on a tour on foot or something all over Japan one day, so would there be some kind of permit to put up a tent anywhere or is it free and would I be able to walk anywhere, like in Scotland where you can walk in any direction and so on or would I also need some kind of permit to do that as well and how much cash would one need need to do the tour and would I be able to work for some cash with out going into some kind of application and getting some kind of housing and so on or will I be able to work for cash in hand for a few hours then leave later on with it?
