The Yayoi culture came from the continent (China). Therefore the transition to the metal culture was not a natural development of the Jomon culture, but a revolutionary change that occurred suddenly as a result of the influence of the continental culture. The technology of wet rice agriculture also came to Japan at this time. Rice became a staple food along with those things obtained by hunting and fishing. It became possible for people to live sedentary lives in the vicinity of their fields; communities increased their supportive power, and there appeared villages of several hundred families. People began to work together ever more closely, and there were divisions in social functions. On the whole, society took on a class structure that was based upon power. Land, which was the principal means by which each family made its living, was not individually owned, but held in common by the village, and so it was necessary to tightly control the use of land and water, and the distribution of agricultural implements and labor. The headman succeeded to this position of authority. One can sense that the birth of the city is nigh, but in the first part of the Yayoi Period people were still abiding by the law of Nature, which states that one must either gather or produce one's own food. Even the village headman still had to grow his own rice. The City's Origins When did the city make its appearance in Japan? We may say that it happened when the gods marked the human race for ruin. When a system made up of the dominators and the dominated, the exploiters and the exploited, became necessary, the city came into existence as none other than the mechanism of domination and exploitation (see note 24). Whether it be Mesopotamia, Egypt, China, or whatever place where ancient civilizations arose, the city did most decidedly not arise as an instrument for the prosperity of civilization (or culture); it was without doubt a mechanism for idleness and gluttony set up by the dominators and their ilk, as well as those hangers on who hoped to profit, such as merchants and craftsmen. Urban civilization (culture) is nothing more than a means of achieving idleness and gluttony. In Japan the city appeared in the latter part of the Yayoi Period. Technology (culture) developed, the scale of communities expanded, and the social organization became complicated. As a result the various regions took on distinctive cultures based on their respective functions, and there appeared villages which were groups of people specializing in the manufacture of clay, stone, or metal implements. Groups of people whose sole occupation was the manufacture of things -- this was without a doubt the beginning of the city.
