“…Carbon and nitrogen isotope analysis with a stochastic mixing model for three Jomon, Epi-Jomon, and early modern (Ainu) skeletal populations in Hokkaido suggested that the protein contribution was 28-35% for marine fish and 42-51% for marine mammals (Minagawa, 2001). Carbon and nitrogen isotopic data from the Usu-moshiri skeletal population in Epi-Jomon Hokkaido suggested that the protein contributions from marine fish and marine mammals were 12-42% and 45-76%, respectively (Tsutaya et al, 2013). Comparing these findings with our results, the dietary protein dependence of the Moyoro adult humans on marine mammals would be greater than that of the other Okhotsk populations in northern Hokkaido and other prehistoric Hokkaido cultures.…”

“…Several studies also recorded that the Ainu people fed their dogs with low-sodium trout (Nishitsuru, 1942;Kasai, 1943). The isotope ratio of trout in Hokkaido is similar to that of brackish-water fish (Tsutaya et al, 2013). Shnirelman (1994) reported that fishers in Kamchatka in the late nineteenth century fed their domesticated dogs with dried or fermented fish and used them to pull sledges.…”

“…The discrimination δ 13 C and δ 15 N values from prey to consumer bone collagen were set as 1.5 ± 0.5‰ (5.0 ± 0.5‰ in the case of C 3 plants) and 4.0 ± 1.0‰, respectively (Lee- Thorp, 2008). Isotope ratios of modern Hokkaido C 3 plants and modern Japanese marine shellfish with correction for the Suess effect (Friedli et al, 1986) were those reported in Tsutaya et al (2013) and Yoneda et al (2004a), respectively. Two applications were independently performed: applications into two dogs and all adult humans.…”

The Okhotsk people were sedentary hunter-gatherer-fishers who lived and prospered in Sakhalin, Hokkaido, and the Kurile Islands during the fifth-thirteenth centuries AD. They expanded rapidly along the north-eastern coast of Hokkaido where archaeological evidence suggests an increasing dependence on hunting marine mammals. In this study, we present the results of carbon and nitrogen isotope analyses of 18 faunal (including two domesticated dogs) and 58 adult human skeletons excavated from the Moyoro site of the Okhotsk culture in eastern Hokkaido. Although the mean human isotope ratios did not differ between sexes, the variances of carbon isotope ratios were significantly greater in males. Carbon and nitrogen isotope ratios suggest that the Moyoro humans and dogs heavily depended on marine foods for their dietary protein intake. The Bayesian mixing model suggests that humans obtained a maximum of 80-90% of their dietary protein from marine mammals, whereas domesticated dogs obtained 2-33%, 3-40%, and 5-45% of dietary protein from brackish-water fish, marine fish, and marine mammals, respectively. This suggests an avoidance of significant dietary overlap between the sympatrically living humans and dogs at the Moyoro site. Significant maritime adaptation would have enabled the subsistence of the Okhotsk people in the harsh northern environment of Hokkaido.

“…Instead, δ 13 C tracks changes in the carbon source of dietary protein and routing through different food webs which in Cis‐Baikal helps to differentiate between terrestrial and aquatic foods, and parse out different fisheries (Weber et al, ), based on the length of the food webs in different types of watercourses (e.g., small mountain rivers, large mature rivers, lake‐shore, and deep‐water lake). In this regard, δ 13 C will primarily help to inform on post‐weaning foods and diet breadth during the first decade of life (Drucker & Bocherens, ; Tsutaya, ), and hopefully shed light on the presence, or absence, of specialised child diets or evidence of child foraging (Eerkens et al, ; Greenwald et al, ; Tsutaya, Sawada, Dodo, Mukai, & Yoneda, ).…”

Reconstructing individual dietary histories at Shamanka II, an Early Neolithic (7000–5700 cal. BP) Kitoi hunter‐gatherer cemetery in Cis‐Baikal, Siberia, revealed surprising intrapopulation variability in childhood diets. Stable isotope analytical data produced by micro‐sampled first molars identified changes in both the timing and rate of weaning for different individuals. Further, examination within the framework of a high‐resolution radiocarbon chronology identified shifting practices between two phases of cemetery use, and additional links with mortuary treatment that indicates differences relating to group and/or family structure. The differential treatment of infants, correlated with the complex hunter‐gatherer social structure, and subsequent burial treatment evident at this cemetery are investigated in light of regional dietary trends.

The urbanization of the city of Edo, the capital of premodern Japan, has been assumed to be not as a result of natural increase but that of in-migration although this assumption has never been verified. To obtain information on natural fertility in Edo, we analyzed stable carbon and nitrogen isotopes in 46 adult and 84 subadult human skeletons excavated from the Hitotsubashi site (1657-1683 AD: the early Edo period), Tokyo, Japan and reconstructed their breastfeeding period, one of the most important determinants of fertility. Adult females are significantly more depleted in (15) N by 0.7‰ than adult males, suggesting a dietary differentiation between sexes and/or the effect of pregnancy. The changes in the nitrogen isotope ratios of subadults suggest that supplementary foods were introduced around the age of 0.2 years and weaning ended around 3.1 years, which agrees with descriptions in various historical documents of the period. The duration of breastfeeding in the Hitotsubashi population was relatively longer than those in modern industrial and traditional societies and four previously reported populations in medieval and in the industrial England. As later weaning closely associates with longer inter-birth interval for mothers, our data suggest a lower natural fertility for the Hitotsubashi population. Assuming that the proportion of married people was also lower in the major cities of the earlier Edo period, our results support the assumption that Edo developed and increased its population by attracting immigrants during urbanization.
