So we all know about these pretty amazing trains they have in the "Land of the Rising Sun". They are always on time, clean, comfortable. But they are somewhat expensive for the average backpacker.
I'm aware of the Japan Rail Pass and I'm really considering buying it for my upcoming trip there but I'm still evaluating alternatives.
What about buses? Would it be possible to sacrifice some comfort in order to save money and move around Japan (Honshu and Kyushu mostly) with flexibility? Is there something like JRP for buses (it would be cool if you could use it even for buses inside cities)?
