Best Japan travel book?

Question:

I would like to go to Japan next year, for 2 or 3 weeks. But more in a backpacking budget style.
Not all that interested in Tokyo, would rather spend more time in the countryside and less touristy places.
Just looking for a nice travel book that would give me nice ideas of where to go and what to do.

Answer:

I think Lonely Planet has one of the best books available. Lots of photos. They also tell you costs of some things.
