After World War II, did Japan why achieved so rapid recovery? And why so slowly recover from the burst-out of bubble economy after 1990? Before answearing this, we have to ask the way of thinking on Japanese social history. And we find out Japanese society was guided in ancient times by the idea of Wa=Peace. And Wa was guided in ancient times that the communal relationship was oriented by the natural-needs of inhabitants. But after 7^<th> Century law-system was introduced into politics. Shogun seeked the second way of law-systematized procedure in Edo Period during 250 years. And divided people into four social classes: samurai, farmer, workman and marchant. But these governed people have changed themselves from possitivity to negative thinking and make themselves lonely. Indeed till today. On this lines there are so many suiciders and lonely death in today's Japanese society.
