Reddit reviews Lonely Planet Journeys: Lost Japan

I really enjoyed Lost Japan by Alex Kerr. It's auto-biographical and has some interesting insights from a Westerner who has lived in Japan and seen it change over the past few decades.

While it may have been written in 1985, I would say that The Roads to Sata: A 2000-mile Walk Through Japan by the late Alan Booth (also a compatriot of yours) would be a must-read before coming to Japan as you are - for an extended visit. Reading it may inspire you to look up some of the obscure places that he visited - although not necessarily all on foot as he did. Another of Booth's works published posthumously "Looking for the Lost" is also worth a read (not to be confused with Alex Kerr's Lost Japan - which is also decent although I think Kerr's book could benefit from a stronger editor when he delves too much into his pronounced artsy-fartsy fetishes)
