Racism in Japan comprises negative attitudes and views on race or ethnicity which are related to each other, are held by various people and groups in Japan, and have been reflected in discriminatory laws, practices and actions (including violence) at various times in the history of Japan against racial or ethnic groups. According to census statistics in 2018, 97.8% of Japan's population are Japanese, with the remainder being foreign nationals residing in Japan. The number of foreign workers has increased dramatically in recent years, due to the aging population and a shrinking labor force. A news article in 2018 suggests that approximately 1 out of 10 people among the younger population residing in Tokyo are foreign nationals. According to the CIA World Factbook, Japanese make up 98.1% of the population, Chinese 0.5%, and Korean 0.4%, with the remaining 1% representing all other ethnic groups. Japan lacks any law which prohibits racial, ethnic, or religious discrimination. The country also has no national human rights institutions. Non-Japanese individuals in Japan often face human rights violations that Japanese citizens may not. In recent years, non-Japanese media has reported that Japanese firms frequently confiscate the passports of guest workers in Japan, particularly unskilled laborers. In the early 20th century, driven by an ideology of Japanese nationalism under the guise of national unity, the Japanese government identified and forcefully assimilated marginalized populations, which included Ryukyuans, Ainu, and other underrepresented groups, imposing assimilation programs in language, culture and religion. Japan considers these ethnic groups as a mere "subgroup" of the Japanese people and therefore synonymous to the Yamato people, and do not recognize them as a minority group with a distinct culture. Background Demographics About 2.2% of Japan's total legal resident population are foreign citizens. Of these, according to 2018 data from the Japanese government, the principal groups are as follows. The above statistics do not include the approximately 30,000 U.S. military stationed in Japan, nor do they account for illegal immigrants. The statistics also do not take into account naturalized citizens from backgrounds including but not limited to Korean and Chinese, and citizen descendants of immigrants. The total legal resident population of 2012 is estimated at 127.6 million.
