Early historic human remains from the Hasekouji-Shuhen site in Kamakura, Japan

抄録

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.
