I do understand where you are coming from.
My plan is to rent a room at a guesthouse for about 60000.
Stay a couple of nights in Okinawa for [i giving myself to about 10000 a night].
And the same applies to possibly Tokyo or other areas that is a long train ride from Osaka. Everything else, however, I might just leave in the early morning, and come back on the last train back to Osaka. Since most of it is in the same general direction, I don't see why it won't work. Though, I haven't looked at travel distances with trains that I can ride with a Rail Pass. Or even if it is cheaper to not use a Rail Pass. Right now, I'm still working on accommodation possibilities, and itinerary, then I'll figure out how to get from place to place.
