Finally more complete than the Backpacker ... unfortunately it is not off the beaten track in Tokyo and Kyoto!
Who will want to get lost in the Japanese Alps (like us) find all he will need in Lonely Planet.
After you may not always find information on a small village in the prefecture of Yamagata ... but if you had to have a Japanese encyclopedia volumes 15 to visit, it would not have happened!
As with everything, to be sure of everything, the place will please me, I'll find my interest, I prefer cross-check information with other guides in libraries or so with the info on the net!
