This article introduces the concept of “Insider minorities”, those whose difference is of a sort that currently does not deny their Japanese-ness in the eyes of other Japanese, as opposed to outsider minorities, who are considered foreign despite their long, even multigenerational, residence within Japan. Most surveys of minorities in Japan have focused on ethnic minorities, including Koreans and Chinese, as well as the indigenous Ainu and Okinawans. The Burakumin ends up being the only non-ethnic group to be included (see De Vos and Wagatsuma, 1995; Weiner, 1997; Ohnuki-Tierney, 1998). Such a focus on ethnic and racial minorities, however, fails to recognize the extent of difference that exists in Japan. Indeed, ethnic minorities in Japan, together with the Burakumin, account for only 4 to 6% of the Japanese population (De Vos and Wagatsuma, 1995, p.272), making it easy for many Japanese, most notably former Prime Minister Nakasone, to claim ethnic and racial homogeneity in contrast to other countries such as the U.S. (Creighton, 1997).
