Hisabetsu buraku
Despite Japan's claim of homogeneity, two Japanese minority groups can be identified. The largest is known as the hisabetsu buraku, "discriminated communities," descendants of premodern outcast hereditary occupational groups, such as butchers, leatherworkers, and certain entertainers. Discrimination against these occupational groups arose historically because of Buddhist prohibitions against killing and Shinto notions of pollution, as well as governmental attempts at social control.
During the Tokugawa period, such people were required to live in special buraku and, like the rest of the population, were bound by sumptuary laws based on the inheritance of social class. The Meiji government abolished must derogatory names applied to these discriminated communities in 1871, but the new laws had little effect on the social discrimination faced by the former outcasts and their descendants. The laws, however, did eliminate the economic monopoly they had over certain occupations.
