The original title in japanese was "The Japanese and the house" and that should have been the English title. Don't expect a sales-advertisement trying to sell you japanese architecture as the world's most perfect, showing you only the most perfect examples, like most books on the subject do; this book was written by a Japanese for the Japanese, so it's not trying to fool anyone. Instead, it addresses the good, the bad and the (very) ugly of Japanese architecture in the 1970s, and gives a lot of recommendations for future development. In this sense, this book feels a lot like "A Pattern Language", from Christopher Alexander.
I finished this book in a weekend. Unlike many other translated books on Japanese architecture, it is written in clear English and talks about daily life issues anyone can understand, and does it with a good (sometimes hilarious) sense of humor. It does not go high on insipid philosophical discussions, but goes deep into the roots of current day virtues and vices of Japanese architecture.
Don't expect color photographs, floor plans or sections; this books was not illustrated by the author, but by the editor. The original work is text-only. Even if it were to be stripped from the b/w photos it has, it is still a very entertaining book, that reads almost like a novel, and will make you learn a lot of things about the realities and problems of Japan while having some good laughs. It's really refreshing to find a book on architecture that talks about real life needs instead of difficult-to-understand philosophical concepts.
