A various artists, archtects, sociologists, activists and communists (ah.. this is a particular person though..) in Japan argues that urban-type survival skills give us many things to re-think about a way of living in Japanese society and its problems. Actually it’s a learning idea to me, however, I have doubts about the edification that Japanese society needs absolutely the knowledge of street people, which is out of social systems. Even though there might be those who are only able to nestle up to the system, their affirmation is only based on a society consisted of micro and macro point of views. Do they really think about the society?
