In Japan’s early modern period (1603–1867), also known as the Edo period, females were considered inferior to males. It is therefore plausible that boys were raised more solicitously than girls, and that girls were subject to various kinds of deprivation in early childhood. We compared the prevalence of linear enamel hypoplasia (LEH) in the dentition of the skeletal remains of early modern Japanese samurai and commoners interred in an urban location (a castle town). Significant sex differences were found in the prevalence of LEH in both groups. As there is evidence that LEH prevalence reflects stress levels in early childhood, the significant differences between the sexes provide material evidence for the hypothesis that male offspring were given preferential treatment among both samurai and commoners in Edo period urban society.
