In the years following the World War II, government-industry cooperation, a strong work ethic, high technology, and a comparatively small defence allocation (1% of GDP) helped Japan advance with extraordinary speed to the rank of second most technologically powerful economy in the world after the United States. Today, measured on purchasing power parity (PPP) basis, Japan became a regional power that was able to defeat the forces of both China and Russia. In the case of Japan, during the 1973 oil crisis, Kaizen helped electronic and machinery companies to lower their costs and keep their end- user prices stable even the food and other items had already stepped up their prices. Kaizen basically helps a company to maintain the profit margin when the price of material costs and labor costs keep increasing following inflation. No doubt exists that the development of codes of professional conduct concerning information behaviour based on relevant technical knowledge and practical experiences is important in Japan. However, codes developed where individuals’ ethics of responsibility are lacking would become just a polite fiction. To compensate for the lack of individuals’ ethics of responsibility by restoring and maintaining Japanese core ethics, it is important to reflect upon the historical circumstances that led to the formation of Japanese core ethical values. Although this task is difficult, it is critical for Japanese people living in the modern information society.
