Restudies on the appearance process of mounded tombs in Hokuriku region of JAPAN SEA coastal area

本研究的目的是从一个新的研究视角来考察日本沿海北国地区墓葬的出现过程、“海路”对文化的影响以及控制交往和贸易的首领。本文以位于富山县平密市的青岛田墓群为研究对象，通过两次考察会、对青岛田A1墓葬遗址的调查、青岛田A2墓葬的发掘，在早期后期(公元4世纪中下半叶)，对青岛田A1墓葬(约70米左右，钥匙孔形状的墓葬)有了明确的认识。A2 Tumulus比这个稍新一些。此外，据早期末期估计，燕艾达努努亚山隆起阶段(107.5m，尾部为四角形的锁孔墓穴)没有出现堆积墓穴，而青岛田A1隆起阶段出现了60-70m级别的堆积墓穴。因此，认为燕艾达努努亚山暴动阶段出现了一个控制广域的主要负责人。考虑到之前的阶段，青田巨浪是重要的。此外，对于正在河米地区建设的富山县规模最大的青田A1和柳野山巨浪，估计主要因素是日本海和一个内陆互动和贸易方式与Noto地区相连。研究日本沿海富山和野户地区墓葬的出土过程具有重要意义。

The purpose of this research is to consider appearance process of mounded tombs in Hokuriku region of Japan SEA coastal area from a new study viewpoint, influences of culture by "coastal route "and chiefs who controls interaction and trade. As a case study, we focused on the Aoshimada -mounded tomb group located in Himi city, Toyama prefecture.Through of twice study meetings, investigation of grave goods about Aoshimada-A1 tumulus, and excavation of Aoshimada-A2 tumulus, it became clear around the latter portion of early stage (middle -latter portion of fourth century) about A1 tumulus (around 70m, keyhole-shaped mounded tomb. A2 tumulus is slightly newer than this. Furthermore, there is not mounded tomb in the stage of Yanaidanunooyama tumulus (107.5m, keyhole tomb with a quadrangular rear portion) estimated with the last portion of early stage, whereas mounded tombs of 60-70m grade appear in areas for the same stage of Aoshimada A1 tumulus. Therefore, It is thought that a major chief dominating wide area appears in the stage of Yanaidanunooyama tumulus. Aoshimada tumulus is important when think about the stage just before that.In addition, as for Aoshimada A1 and Yanaidanunooyama tumulus of the greatest scale in Toyama prefecture being built in Himi area, it is estimated main factors that the Japan Sea and a lagoon, an inland way of interaction and trade to be connected with Noto region. It is important when study appearance process of mounded tombs in Toyama and Noto region, Japan Sea coastal area.
