Crown cusp areas of the maxillary second molar are described for the Jomon people, and compared within the Jomon groups, then with the modern Japanese and Hokkaido Ainu. The relative hypocone area slightly varies within the late Jomon groups, while there was no significant difference between the average late Jomon, modern Japanese and Ainu. However, the early Jomon people possess the larger relative hypocone area that the late Jomon people, suggesting that they retained rather primitive feature in the upper second molar compared to the later Jomon people. On the contrary to the existence of such inter-and intra-population variability in the hypocone size, significant difference was not found in the relative metacone area within the Jomon people or between the Jomon, Japanese and Ainu.
