 note = {The first population to occupy the Japan archipelago migrated there more than 30 000 years ago and established the Jomon culture around 12 000 years ago.1, 2 The second wave of migrants, which possessed advanced culture such as wet rice agriculture, weaving and metalworking, migrated to Japan around 2300 years ago and they gave rise to the Yayoi culture.2 Hanihara3 proposed the ‘dual structure’ hypothesis, which explains the origin of the current Japanese population by proposing an admixture of these two major migrant populations, rather than a transition of the Jomon into the Yayoi. Hanihara’s hypothesis is supported by the morphological, cultural and genetic similarity between Ryuku and Ainu peoples, whose populations are separated by considerable distance, with the Ryuku residing in Okinawa and Ainu in Hokkaido.},
