I found this book hilarious, and felt it did a great job of highlighting cultural differences between Japan and the West. But how would I know? I've never been to Japan and know little about that country. I'd be fascinated to know whether Japanese readers would see this as an accurate but gentle satire of their behavior, or on the contrary a crude and vulgar denunciation.
Basically the story is this: a fat Swiss businessman on an assignment in Japan invites a pretty girl to meet him for an excursion to a famous island resort. Unfortunately for him, one of his Japanese contacts catches him in the act and takes it upon himself to organize what he sees as a much more suitable outing for the "distinguished foreign guest". The following day, he rounds up 3 gentlemen whom he wishes to entertain alongside the foreigner. Being on good terms with a foreigner will increase his standing among his own people, while treating him to a lavish banquet can only flatter the foreigner, or so he thinks. Everything, in fact, goes pear shaped for everybody involved. The foreigner, who is exclusively interested in sleeping with the pretty girl, tries his best to dodge the businessman, but in vain, since the railway employees see it as their duty to intercept him and ferry him in style to the island. To honor the foreigner, the station master packs him into a car, and since the bridge to the island is only meant for pedestrian traffic, an accident ensues in which the foreigner's luggage is lost and some people are injured. The pretty girl herself does show up, since after all she has accepted 10 yen from the foreigner to finance the trip, but she comes with 2 friends, including a mother with a young son in tow. Being in no hurry at all to meet up with the foreigner, they more or less deliberately miss the agreed train and spend ages buying each other trinkets that cost a lot more than the trip itself. When they eventually show up at the hotel, the businessman and the management join forces to foil any contact between the foreigner and the girl, not to protect her virtue, but because she comes from the wrong suburb and they see her as not good enough for a foreigner. The hotel owner is prepared to pay a small fortune for a geisha to spend time in the foreigner's bedroom so that things are done in the traditional manner.
The conclusion left me a little bewildered. The pretty girl receives a phone call from her grandmother telling her she has to return to Tokyo immediately to get married. While walking on the beach she meets a young man to whom she confides her misgivings about this impending wedding. While she likes her fiancé well enough, she is scared of her future in-laws and would rather wait until her fiancé had finished college. The young man sympathizes and they end up making love on the beach. When he wakes up, the girl has gone and he finds out that she committed suicide by drowning just after leaving him. Given the farcical tone of the book so far, I was taken aback by this brutal ending.
The story is told in 8 chapters, each from the point of view of one of the protagonists. This is a judicious choice as it enables the author to let Japanese men and women of different rank express their values and feelings. Raucat conveys the impression that the Japanese spend a lot of time and money complying with meaningless rituals, but even if he made fun of the Japanese I didn't feel he looked down upon them.
