The concept of agricultural fundamentalism emerged in the later period of the Tokugawa Shogunate was renewed in the early Meiji era, and had been predominated until the end of World War II. However, a new thought on the nation-building depending either on commerce and manufacture or on international trade had already come out even just before the Meiji Restoration. Since that time, this new thought had gradually earned a stronger national support during the long period before World War II. After the war, the policy for nation-building depending on international trade has become the principle for the development of economy, overwhelming the concept of agricultural fundamentalism. In terms of economic growth of the nation, a great success has been attained in the last decade. In short, Japan has become an economic power, while at the same time, her agriculture has begun declining. Now that economism is presently predominating in Japan.
