I bought a used book from a japanese author called MURAKAMI RYU.
If someone is familiar with the movie Tokyo Decadence he's the guy who wrote the novel and shot the movie.
The book I found was "In the Miso Soup" a meeting of a young japanese guy who organizes sex tours for foreigner business men or tourists and an american weird guy... everything is fine until the japanese guy notices a 10000 yen with money on it, just after he read about a young highschool girl beheaded, dismembered and left in a sewet without arms and legs.
(Beheaded, Dismembered and left in a sewer . could sound like a C.C. song...)
Of course you might think the american is weird... but much more interesting is the way the japanese life is shown... thumbs up, even if I read it in two hours...
