"In Japan, nikkeijin literally means: a person with ties to Japan; the term is used to describe persons of Japanese descent. Up until the third generation, nikkeijin are allowed to stay in Japan on long-term visas that include an unlimited work permit ... They often work under temporary contracts for the big names in the automobile, heavy, and electronic industries ... [and] have taken over Japan’s 3K jobs, the ones that are kiken (dangerous), kitsui (tough) or kitanai (dirty). nikkeijin are the only foreign workers legally allowed to do so." (Quoted from article)
