Thus, in spite of the widespread belief that Japan is ethnically homogeneous, at least one academic recommends description of it as a multiethnic society.[10] Internal to Japan, a distinction between 'Polynesian-type' (darker-skinned, round-eyed) Jomon and 'Continental-type' (lighter-skinned, narrow-eyed) Yayoi is sometimes observed, although the popular shorthand does not actually reflect the observed 90% Yayoi / 10% Jomon haploid-group frequency of modern Japanese DNA.
More than 2.5 million (potentially higher because of undocumented migrants), 14.9% up in five years. North and South Koreans 1 million, Chinese 0.6 million, Filipinos 0.5 million, Brazilians 250,000 and Peruvians 200,000. Other nationalities (examples): Americans, Canadians, Australians, British, Indonesians, Thais, Africans, Iranians, Russians, Turks, Indians and others.
