Japanese law

The Law of Japan refers to the entirety of the legally achieved norms in Japan.

Pre-Modern History

The early laws of Japan is believed to be heavily influenced by Chinese law. Little is known about Japanese law prior to the seventh century, when the Ritsuryō was developed and codified. Before Chinese characters were adopted and adapted by the Japanese, the Japanese had no known writing system with which to record their history. Chinese characters were known to the Japanese in earlier centuries, but the process of assimilation of these characters into their indigenous language system took place in the third century. This was due to the willingness of the Japanese to borrow aspects of the culture of continental civilisations, which was achieved mainly via adjacent countries such as the Korean kingdoms rather than directly from the Chinese mainland empires.

Two of the most significant systems of human philosophy and religion, Confucianism (China) and Buddhism (India), were officially transplanted in 284–5 and 522 AD respectively, and became deeply acculturated into indigenous Japanese thought and ethics. David and Zweigert and Kotz argue that the old Chinese doctrines of Confucius, which emphasize social/group/community harmony rather than individual interests, have been very influential in the Japanese society, with the consequence that individuals tend to avoid litigation in favour of compromise and conciliation. In addition, it is presently believed that various arts and techniques in many fields of production, such as agriculture, weaving, pottery, building construction, medicine and tanning, were brought to Japan by immigrants by way of the Korean peninsula. These immigrants, wherever they came from, had significant influence on the development of Japan.

It is theorized by some that the flow of immigrants was accelerated by both internal and external circumstances. The external factors were the continuing political instability and turmoil in Korea, as well as the struggle for central hegemony amongst the Chinese dynasties, kingdoms, warlords, invasions and other quarrels. These disturbances produced a large number of refugees who were exiled or forced to escape from their homelands. Immigrants to Japan may have included privileged classes, such as experienced officials and excellent technicians who were hired in the Japanese court, and were included in the official rank system which had been introduced by the immigrants themselves. It is conceivable - but unknown - that other legal institutions were also introduced, although partially rather than systematically, and this was probably the first transplantation of foreign law to Japan.
