Abstract:The Seiyokan site is located in Kamakura, Japan, and has yielded 91 human skeletons belonging to the 14-15th centuries AD. The purposes of this study are to examine the human crania from the archeological site at Seiyokan, to analyze the presence, distribution, and variability of their weaponrelated traumas, and finally to better understand violence in medieval Japan from osteological evidence. The results demonstrate that the traumas on the crania have morphological features consistent with human-induced cut … Show more
“…Several preceding studies have shown that human skeletons from medieval Japan exhibited traumatic injuries related to violence, such as gashes, decapitations, blows, stabbing, and scratches (Suzuki et al, 1956;Morimoto, 1987;Morimoto and Hirata, 1992;Hirata et al, 2004;Nagaoka et al, 2009Nagaoka et al, , 2010. The results of this study demonstrated the presence of weapon-related traumas on the cranium and limb bones.…”

The chronological ages used in the comparative samples are the Jomon (14500-300 BC), Yayoi (300 BC-300 AD), medieval (1185-1573 AD), and Edo (1603-1687 AD) periods.…”

“…Nagaoka et al (2006) compared the urban sanitation situation between the medieval and Edo populations and considered that population concentration in medieval Kamakura had impacted negatively on the lives of the inhabitants. Urban sanitation of the water supply and waste disposal was not provided there and the observation of injured skeletons by Nagaoka et al (2009Nagaoka et al ( , 2010 implied the possibility that some of the medieval Japanese individuals were drawn into direct or indirect involvement in violence and warfare. In Edo-period Japan also, the mortality rate was higher in urban areas than in rural areas (Kito, 2000).…”

“…The first author of this paper (T.N.) and colleagues analyzed them and indicated several new findings regarding paleodemography and paleopathology of the medieval Japanese: (1) the paleodemographic study of the YM and YCSB-372 series demonstrated a higher proportion of deaths in young individuals than the Edo period (1603-1867 AD) Japanese and implied severe living conditions in medieval Kamakura due to malnutrition and warfare (Nagaoka et al, 2006;; (2) the paleopathological study of the YM site revealed the first evidence for leprosy and tuberculosis in medieval Japan (Hirata et al, 2011) and less frequent degenerative changes in spines than the Okhotsk and Kumejima skeletal series (Shimoda et al, 2012); and (3) the presence of cut marks on the crania from the Seiyokan, YM, and YCSB-372 sites strongly suggested the prevalence of violence in medieval Japan (Hirata et al, 2004;Nagaoka et al, 2009Nagaoka et al, , 2010. These studies have revealed the life and death situations of the urban inhabitants of medieval Japan from multiple perspectives and a tentative hypothesis is that the medieval people suffered from poor health due to malnutrition and interpersonal violence.…”
The purposes of this study are to conduct paleodemographic and paleopathological analyses of medieval human skeletons from Japan and to clarify their life and death situations. The materials used here were individuals from the Yuigahama-chusei-shudan-bochi site (Seika-ichiba location) (i.e. YCSB-SI), located along the Yuigahama seashore of the southern end of Kamakura City. Several new findings regarding the life and death situations of YCSB-SI were obtained: (1) YCSB-SI exhibited a younger age-at-death distribution than other skeletal series; (2) the frequency of caries lesions in YCSB-SI was 5%, females exhibited more caries lesions than males and this group exhibited the lowest caries prevalence rate among Japanese populations; (3) the frequencies of enamel hypoplasia were 67% in the upper central incisors and 73% in the lower canines, which were almost equal to those of non-medieval series; and (4) the presence of weapon-related traumas on the cranium and limb bones from YCSB-SI was demonstrated. It is inferred from the present and previously reported data that population concentration in Kamakura impacted negatively on the lives of the inhabitants, possibly by malnutrition, increase of infectious diseases, and occasionally death by violence, and that all the results can be consistently explained by assuming urbanization and severe living conditions in medieval Kamakura.

“…Medieval Kamakura and early-modern Kumejima peoples Intensive paleodemographic research has been performed and has revealed that the medieval Kamakura people were not long lived (Nagaoka et al, 2006;Nagaoka and Hirata, 2008). In addition, many weapon-related traumas were found among the skeletal remains from medieval Kamakura (Suzuki et al, 1956;Hirata et al, 2004;Nagaoka et al, 2009Nagaoka et al, , 2010. However, there have been few studies on the life activity patterns of these people.…”
Degenerative changes of the spine in people of the Okhotsk culture were investigated in adult human skeletal remains from 38 males and 34 females. These findings were then compared with those in materials obtained from the medieval Kamakura period and early-modern peasants on Kumejima, Ryukyu Islands. The three samples clearly showed different patterns. In the Okhotsk series, the cervical spine of each sex had most osteophytes on the vertebral body, while the Kumejima samples had the highest frequency on the lumbar vertebrae. In the Kamakura series, males were most affected on the lower thoracic vertebrae. Moreover, severe osteophytes on the body of the lumbar vertebrae were more frequently seen in the Okhotsk males. Degenerative changes of the articular process of the Okhotsk series were most frequently seen in the lumbar vertebrae and least frequently seen in the cervical vertebrae. This is well contrasted with a high frequency of degenerative changes of cervical apophyseal joint in early-modern Kumejima peasants. The Kamakura series of each sex had generally low frequencies. Severe degenerative changes of apophyseal joint dominantly affected the Okhotsk series. It is inferred that different dynamic loads caused a high frequency of degenerative changes in the corresponding articular parts. For example, because the Okhotsk culture developed a considerable maritime infrastructure, the lifestyle required for sea-mammal hunting and fishing seems to have particularly affected the incidence of severe degenerative changes of the lumbar vertebrae.
Weapon-related traumas on human skeletons provide us with direct evidence of violence in archaeological and forensic contexts. The purposes of this study are to describe the weapon-related traumas on Edo-period (AD 17th-19th centuries) human skeletons from the Hitotsubashi site (Tokyo, Japan), to examine their presence, distribution and variability, and finally to better understand violence during that period. The specimens observed here are two adult males exhibiting eight traumas: five sharp-force traumas caused by edged blades (62.5%) and three blunt-force traumas with radiating fractures (37.5%). The frequency of individuals with traumas is 1.0% out of 207 individuals and 3.3% out of 64 adult males. The traumas found on the Hitotsubashi crania are distinguishable from those on the medieval crania in terms of low traumatic frequency. These observations shed new light on the life and death situations of the Edo inhabitants from osteoarchaeological perspectives.
