From obsidian from the sea' to obsidian from the mountains'
                     : Obsidian trade revealed from Mitakadanma site

IKEYA Nobuyuki

Abstract: This paper focuses on the Mitakadanma site, situated on the cape protruding from the southeast coast of Izu area, where Jomon people discharged obsidian taken from Kozu island, 60km off the coast. Provenance analysis of obsidian and pottery, together with settlement analysis, indicates that a mobile group visited Mitakadanma site seasonally and was specially engaged in obsidian trade in the early Middle Jomon period. In the latter half of the Middle Jomon, people settled at the site and controlled the distribution of obsidian. The settlement site has pottery which was brought in from the Kanto-wide area including Kanagawa and Yamanashi prefecture, suggesting that it was exchanged for obsidian. Mitakadanma site was abandoned at the end of Middle Jomon period when the amount of obsidian distributed from Shinshu area to Kanto region increased. Increased production at the sources of Hoshikuso Pass and Hoshigato in Shinshu area led to full-scale mining activity in the middle Late Jomon period.

The spread of Buddhism in ancient Japan
      : With special attention to exchanging Buddhist images, sutras and priests

HISHIDA Tetsuo

 

Abstract: Diffusion of the earliest Buddhist temples ranged from Miyagi to Kumamoto prefectures, mostly covering the domain of Japanese ancient state, at the end of the seventh century AD. This paper aims to view the spread of Buddhism in Japan as a process of contact with an external culture and its subsequent adoption, and also to reconstruct the policy of the state government which underlay the process. First, the author shows that exchange of thoughts and cultures by Buddhist priests can be verified by both written documents and archaeological data. Second, it is demonstrated that the set of thoughts which gave birth to the first local temples had been configured with the foundation of Kudarataiji (Great Paekche Temple) in the middle of the seventh century, and that the government attempted to popularize nation-protecting Buddhism-based on the belief in Shitenno (the sacred quartet of guardian gods) and Konkomyokyo (the sacred text of the holy light). The layouts of temple complexes which were closely related to the principles of Buddhism, are also thought to have spread in accordance with Buddhist propagation in the government. The author concludes that the ultimate purpose of the policy of providing temples was to extend the idea of nation-protecting throughout the domain and to simultaneously force the introduction of a nation-protecting chant service within the Buddhist religion.

Keywords: Spread of Buddhism; traffic of Buddhist priests; belief in Shitenno (the sacred quartet of guardian gods); Konkomyokyo (the sacred text of the holy light); layouts of temple buildings complex; domain of the state and range of propagation.


ARTICLES

Analysis of the funeral practice on the square projection of mounded tombs
                                   in the Kofun period

FUCHINOKAMI Ryusuke

Abstract: This paper discusses the background of the variation in funeral practices on tsukuridashi (square projections on the constricted part of key-hole shaped mounded tombs), by examining the alignment and composition of artifacts from the Kofun period (AD 4-6th century) discovered on and around the facilities. Based on analysis of artifacts found on tsukuridashi, the author recognizes two phases in the transformation of funeral practices on tsukuridashi, the latter of which includes several types of ritual. Each type is defined in relation to the outer facilities of the mound, and the composition of the same type of ritual can vary according to the shape and the size of the mounded tombs. Examination of the formation process of the rituals on tsukuridashi indicates that earthen vessels were the most fundamental component of the ritualistic items. He also considers that the invention of human-shaped haniwa (earthenware) added new meanings to the ritual and its selective adoption created more variations in styles of funeral practice in the late Kofun period in Japan.

Keywords: Tsukuridashi (square projection); haniwa; funeral practice; Kofun period of proto-historic Japan.


RESEARCH NOTE

A cognitive archaeological study of chronological change in pottery categorization
    : Relationship between the Itazuke type and clay-band type in the Yayoi period

KUROKI Rie

 

Abstract: This article presents a case study of cognitive archaeology concerning the categorization of prehistoric material culture. The author examines the emic categories of prehistoric agents by analyzing the pots from the Early to the first half of the Middle Yayoi period northern Kyushu. The pots were classified into seven types and their percentage in each phase was calculated. The result indicates that each type should not be considered as a lineage' as has been assumed by many archaeologists, but should better be recognized as being constituted from prototypic and marginal members according to the categorization theory in cognitive psychology. Based on the cognitive model, the observed chronological change can be explained as follows: the agents had clear mental categories of two distinct types of pots at the beginning of the Early Yayoi period, which eventually merged into one as the increase of intermediate members obscured the cognitive distance between the prototypes of the original two categories. The author concludes that categories of material culture should be considered as having been produced by the dynamic cognitive process of the agents.

Keywords: Cognitive archaeology; category structure; prototype; Yayoi pottery; Early Yayoi period.
