Abstract
HANIHARA estimated the number of overseas migrants to ancient Japan during the 1, 000 years from the third century B. C. to the seventh century A. D. by employing a population growth model in conjunction with a morphological change model (J. Anthrop. Soc. Nippon, 95(3) : 391-403). Demographic comments in this article regard 1) the consistency in the equation for population simulation, 2) adequacy in hypothesizing annual migrants in the equation, 3) ways of evaluating the probable range of population growth rate during the thousand years, 4) the smooth connection of the population growth curve for the period concerned, in terms of the preceeding neolithic Jomon, and the succeeding historic times, and 5) others.
