For Fukui's Sake by Sam Baldwin is an account of an English guy's two years as an English teacher in Japan.
Its what you'd expect from a first time author.
He was sent to a small city in Japan, Fukui, but traveled around the country a bit. His account of climbing Mt. Fuji is interesting. Apparently you just walk to the top. And apparently its tiring and you'll never want to do it again. Its the same story with climbing Africa's Mt. Kilimanjaro, according to Michael Crichton's Travels.
The author's comments on living in Japan and about the Japanese people are interesting too.
I'd say, however, that if you want to read a book about traveling somewhere, then I'd recommend a book from Roosh, Naughty Nomad, or Neil Skywalker instead.
