In characterising the Japanese way of business, Professor Okumura has
made one of the most significant contributions to the study of
economics. Following his study of the conversion of prewar zaibatsu to
postwar groups of enterprises, he worked on the roll of comprehensive
trading companies in these groups, the main banking system and the
permanent employment system. However, he is very critical of this way of
business, whereas those influenced by him are enthusiastic in its
appreciation. This is the first English translation of his work.
