The reconstruction of everyday diets in villages is important for understanding the diversity of diets and commerce networks of food items in premodern Japan. However, premodern diets in villages have not been well studied compared with those in cities. In this study, stable isotope analyses were performed on 23 adult human skeletons excavated from Sendaiji, a mountainous woodland village of underground Christians in Osaka in premodern Japan. No significant isotopic differences was found between individuals identified as Buddhists and those identified as Christians or between females and males. The total mean carbon, nitrogen, and sulfur isotope ratios were –21.1 ± 0.4‰, 11.6 ± 1.0‰, and 8.9 ± 1.3‰, respectively. The carbon isotope ratios in Sendaiji were the lowest among the studied premodern populations probably because these individuals consumed woodland foods that are affected by the canopy effect. No significant correlation between sulfur and nitrogen isotope ratios was apparent, suggesting that there was little contribution from marine foods or marine fertilizers to the diet of individuals in premodern Sendaiji. The relatively high nitrogen isotope ratios in Sendaiji were possibly because of the denitrification in paddy rice fields, ammonium uptake by paddy rice, use of animal fertilizers, and/or consumption of freshwater fish. To our knowledge, this is the first detailed bioarchaeological study of the premodern diet in a mountainous village in western Japan.

The development of the modern industrialized food production system has resulted in a homogeneous human diet worldwide. However, it is not clear whether a developed food production system led to a homogenized human diet also in ancient societies. Due to the lack of large archaeological datasets, we know little about the chronological trends and ancient circumstances of dietary homogenization. Here we compiled carbon and nitrogen stable isotope ratios, indicators of palaeodiet, of adult human skeletons from premodern mainland Japan (AD 1603–1868, n = 318) to investigate chronological changes in diet. Comparison with datasets from Japan in modern, premodern (Edo), and foraging (Jomon) periods showed that the human diet was rapidly homogenized isotopically in modern times. Premodern people in Japan typically obtained dietary proteins from C3 crops and fish, and the establishment of agriculture created a new isotope dietary niche compared with the foraging period. Dominant protein contributions from agricultural C3 crops cultivated with organic fertilizers and/or rice that are grown in paddy fields with denitrification increased premodern human nitrogen isotope ratios without increasing their carbon isotope ratios. Diet differed according to the social status of individuals or the availability of foods, and a unique diet can be seen in people in higher social classes such as the Shogun family. Meta-analysis of stable isotope ratios of archaeological human skeletons enables a comprehensive understanding of human dietary change through time and regional variations.

Obtaining genetic information about early humans is indispensable to our understanding of the demographic history of mankind. In the present study, we performed a detailed mitochondrial DNA (mtDNA) analysis of a skeleton of the initial Jomon era unearthed from the Yugura cave site in Nagano, Japan, which was dated to 7920–7795 calBP by direct 14C dating. mtDNA of the Yugura skeleton was designated to haplogroup D4b2, which is widely observed in present-day East Asians, including the Japanese, but is absent in Hokkaido Jomon people. This finding indicates that the basal population of Japan was heterogeneous with respect to their mtDNA lineage. This is the first report on the genotype of the people from the initial phase of the Jomon period.

Two complete dog skeletons were recovered during archeological excavations from 1961 to 1970 at the Kamikuroiwa rock shelter, a site that yielded a series of cultural entities from the Late Pleistocene, Incipient Jomon, and Early Jomon periods. Since two dogs were buried close to human skeletons, it was thought that these dogs had been buried by Jomon people, and hence provided the oldest direct evidence of Canis domestication in Japan. However, the stratigraphic information and archeological contexts of these dog skeletons are incomplete due to the lack of detailed excavation reports and technical limitations of excavations at this site. Because the date of the dog burials has not been fully discussed in the context of modern chronology or recent discussions on Canis domestication, we directly measured radiocarbon ages and stable isotope analysis on two dog burials and one set of human remains from the Kamikuroiwa rock shelter. These data are important for reconstructing the relationship between humans and dogs in the Jomon period. Our results show that the human thought to have been buried with the dogs was assigned to the middle Initial Jomon period (8977–8725 calBP), whereas, on the other hand, dates for the dog burials are very close to each other and were assigned to the latest Initial Jomon or the initial Early Jomon periods (7414–7273 calBP). Although these results are not consistent with previous archeological interpretations for this site, they remain important because these two dog burials are among the oldest evidence of Canis domestication in East Asia.

We examined fragmentary human skeletal remains from Escalon Cave near Surigao City, northeastern Mindanao, the Philippines, with respect to the morphology of bones and teeth, radiocarbon dating, and mitochondrial DNA (mtDNA) haplogroup. These remains contained parts of the left temporal bone, the right humerus, the right femur, the upper right first and second premolars, and the first molar. They are presumed to belong to an early-middle adult male, whom we named the Escalon Man. Using the femur sample, we estimated the 14C date of the individual at 2692 ± 39 years BP (uncalibrated). His stature, estimated from the maximum femur length, was about 170 cm—this makes him much taller than the Aeta and the Mamanwa, who are indigenous negrito hunter-gatherers of the Philippines. The femur is sturdy and shows well-developed muscle markings. Numerous narrow grooves on the humerus were found in close proximity to each other, but we could not prove whether these are artificial cut marks made by humans with sharp-edged tools or scratches from some non-human entity. The mesiodistal crown diameters of the molar and premolars are large and resemble those of native Oceanians. Analysis of mtDNA haplogroup was carried out using a DNA sample extracted from a molar. A next-generation sequencer was used to determine the nucleotide sequences of the mtDNA genome. The results indicated that the Escalon Man belongs to the haplogroup E1a1a, which is known to be the marker of Austronesian-speaking agriculturist populations that originated in Taiwan and spread southwards through the Philippines to the Western Pacific, since about 4000 BP. Thus, the Escalon Man was likely a member of the late Neolithic or early Metal Age agriculturist peoples who settled in northeastern Mindanao and who may be the ancestors of the territory’s present-day occupants, such as the Manobo.

A new excavation of the Iyai rock-shelter site has uncovered more than a dozen human skeletal remains from the Initial Jomon period. We describe here an almost complete female skeleton (Iyai 1), and examine this in the context of morphological variation in Jomon females, especially those of the Initial Jomon period. Two radiocarbon dates based on the Iyai 1 skeletal samples show a calibrated date c. 8300–8200 calBP, belonging to the later part of the Initial Jomon period. The Iyai 1 skeleton was found in a burial pit with an unusual body placement. Although it was a flexed burial with the both arms and limbs flexed, the upper and lower body was disconnected at the waist and the two portions placed on top of each other: the upper body was laid on its abdomen with the head faced into the pelvis, and the lower body was found under the upper trunk in a supine position. The individual is a young female, 146 cm in height using Sasou–Fujii method, and the age at death is estimated as c. 20–40 years. The neurocranium is long (cranial index = 79.9) and high (length–height index = 77.1), the face is wide and low (upper-facial index = 43.4). The dentition shows nearly horizontal heavy wear but no dental caries with an edge-to-edge bite occlusion. The postcranial long bones are gracile, although they exhibit clear musculature impressions in some attachment areas. No paleopathological bone modification was found. The talus exhibits a ‘squatting’ facet at the anterior contact of the talocrural joint. The stable isotopic signature of Iyai 1 falls among those of the inland Initial Jomon people, indicating that her proteins mainly came from C3 plants and terrestrial animals.

Eight human skeletons in a good state of preservation have been recovered from excavations at the Hasekouji-Shuhen site in Kamakura city, Kanto region, Japan. We conducted AMS radiocarbon dating that revealed the skeletons to belong to the early historic Asuka, Nara, and early Heian periods (circa 670–970 calAD). In terms of their cranial, dental, and limb bone measurements, the Hasekouji-Shuhen skeletons exhibit morphological characteristics that show affinities with the earlier Yayoi series, which are generally considered to represent immigrant populations from the Asian continent. Furthermore, an early indication of dolichocephalization was observed in these early historic people, a trait which became more pronounced in later medieval times. Three adult males have scars that may have been caused by assaults with a spear or a sword-like weapon. One male individual exhibits skeletal abnormalities including multiple cartilaginous exostosis.

A draft whole genome sequence of a Jomon woman from the Ikawazu shell-mound site has been reported recently. The adult woman, IK002, was excavated with a child, IK001. Because of the burial situation with the child located above the adult, the two individuals were thought to be a mother–child relationship. In this study, we conducted a target capture sequencing, and obtained 258-fold coverage of the complete mitochondrial (mt) genome sequence of IK001. Comparing the mtDNA nucleotide sequences of IK001 and IK002, we found these were unambiguously different from each other. Thus, the mitogenome sequence analysis clarified that both have a non-mother–child relationship. This result sheds new light on the relationship between burial and kinship in Jomon archaeology.

In order to further understand the genetic status of the Okhotsk people, who were distributed in southern coastal regions of the Okhotsk Sea during the 5th–13th centuries, nucleotide variations in the hypervariable region (HVR) and the coding regions of mitochondrial DNA (mtDNA) were analyzed. Targeting the coding regions provides reliable genetic information even from ancient DNAs that may have suffered post-mortem damage. MtDNA haplogroups of 38 individuals were classified according to mtDNA lineages known in northeastern Asian people. Comparisons of mtDNA haplogroup frequencies between the Okhotsk people and other Asian populations revealed that the genetic structures of the Okhotsk people are very similar to those of populations currently living around lower regions of the Amur River and the Ainu of Hokkaido. The results support our previous study on molecular phylogeny of mtDNA HVR 1 sequences, and strongly suggest that the Okhotsk people originated around the lower regions of the Amur River and became an intermediate of gene flow from the continental Sakhalin people to the Ainu.

This paper discusses a probable case of pediatric mandibular osteomyelitis (OM) from the east Hokkaido Okhotsk (5th–13th century AD) site of Moyoro, Japan. The remains of a young child present an unusual mandibular lesion exhibiting two main features: (1) cortical thickening reflecting periosteal new bone formation, and (2) lytic alveolar destruction with associated antemortem tooth loss. The lesion was examined macroscopically, microscopically, and via computed tomography imaging. A differential diagnosis—considering lesion appearance, location, and the age of the child—is most consistent with OM, while alveolar and dental involvement suggest an odontogenic source such as an infected tooth germ. The infection appears to have been active at the time of death and chronic (i.e. of 4+ weeks) in duration, an interpretation supported by enamel hypoplastic evidence of physiological stress in the preceding 12–18 months. The lesion’s unique appearance highlights the diverse manifestation of OM, especially in the jaws and in the absence of modern therapeutic treatment. Despite being considered a relatively common condition among non-adult individuals in the past, surprisingly few cases of pediatric OM have been reported from archaeological contexts. This case, only the second documented on a mandible, contributes to the general paucity of paleopathological literature on OM.
