The tendency toward sectionalism is especially pronounced in the higher levels of Japanese bureaucracy because each ministry separately and independently carries out its personnel administration. Within this bureaucracy the Finance Ministry occupies a relatively advantageous position, and to a certain extent, controls other ministries. The conservative fusion led to a significant rise in the bureaucracy's political influence. This development happened to coincide with the “growth” of the economy. The result is the marked increase in the influence of the Ministry of Trade and Industry, directly responsible for promoting the economic “growth policy”, and the Finance Ministry, responsible for controlling economic growth as a whole. The author analyzes the Income Doubling Plan, the crux of the “growth policy”, to ascertain the value system of the bureaucrats in solving or not solving political as well as economic difficulties. He concludes that the bureaucrats at first resisted and then accepted the “growth policy” in both instances because of and in order to defend their value system of “honesty and steadfastness”.1.
