According to the MOJ, there were nearly 1.85 million legal foreign residents as of 2002. The largest group, at approximately 625,400, was ethnic Koreans, followed by Chinese, Brazilians, and Filipinos. Despite improvements in legal safeguards against discrimination, Korean permanent residents (so-called Zainichi Koreans, most of whom were born, raised, and educated in Japan) were subject to various forms of deeply entrenched societal discrimination. Harassment and threats against pro-North Korean organizations and persons reportedly have increased since the 2002 admission by North Korea that it had kidnapped more than a dozen Japanese citizens. Other foreigners also were subject to discrimination. There was a widespread perception among Japanese citizens that foreigners committed many crimes. According to a government survey, more than 70% of citizens worried that an increase in the number of illegally employed foreign workers could undermine public safety and result in human rights abuses against the workers themselves. Nevertheless, more than 80% said the country should accept foreign laborers conditionally or unconditionally.
