Just started reading a very interesting book: Made in Tokyo, by Kaijima, Kuroda, and Tsukamoto. It is a bilingual book that look at the non designed but interesting buildings in Tokyo. Quoting a small passage from the beginning of the book: From <Architecture> towards <Building>

The buildings of Made in Tokyo are not beautiful....... They are not 'pieces' designed by famous architects. What is nonetheless respectable about these buildings is that they don't have a speck of fat. What is important right now is constructed in a practical manner by the possible elements of that place. They don't respond to cultural context and history. Their highly economically efficient answers are guided by minimum effort. In tokyo, such direct answers are expected. They are not imbued with the scent of culture; they are simply physical 'buildings'.
