Abstract
1) The head-burial site or the "Kubizuka" is located at the seashore of Sembon-hama, Numazu City, Shizuoka Prefecture. According to the local tradition, a number of corpses, which died on the occasion of medieval battles taken place in the middle of the 16th century in this asea, were buried in the Sembon-hama beach. In 1900, a neighboring volunteer collected exposed human bones from the beach and reburied them under the present Kubizuka's monument.
2) On the basis of temporal bones, total number of skeletons buried in the site are estimated to be over 105 individuals, of which 2/3 are supposed to be of male sex and 1/3 of female.
3) Marked traces of injuries were recog-nized on some of the skulls, such as sharp incisions by swards, scratch injuries by sliding swards, round perforations by stabbing with pointed weapons as well as some sawn injuries.
4) Comparing the Kubizuka people with the medieval war-deals from the Zaimokuza site (A. D. 1333) in cranial features, the former coincide exactly with the latter. This will suggest that the burial site ori-ginated from the medieval age as the stated local tradition.
5) Based on the skulls excavated from several medieval sites, so far reported, the typical cranial features of the medieval Japaneses will be summerized as follows: dolichocrany, chameprosopy, chamaeconchy, platyrrhinny and flattness of nasal root.
