I never been to Japan before, but i like the culture. In culture i mean polite and clean compared to some country's. I love to go there, because i love computers. I dont know much about which hotel or place is cheap to stay. I know it can be pretty expensive so im saving up. In the past few years ive been researching about how to travel through Japan the cheap way. Of course you can go with
bicycle, but that would take forever if you have the time. Then again you would see every bit of Japan and you have the freedom to go wherever you want.
My second option was go with bus named willerexpress

I never been on that bus before, but it seems great and cheap. I dont think you will have a lot of showers in the morning, because most of the time you sleep in the bus. Thats what i think it would happen. Then again you need of course a shower otherwise the bus will have a bad odor. ^^
