Research on Regional Characteristics of Ancient Metal Production--Especially of Copper and Iron in the San'in Districts--

至于三因地区的古代金属生产(铜和铁)，有以下几个问题引起了市民和学者的极大关注，即平川町小金谷遗址出土的大量雅代青铜器是在哪里出土的问题，以及以古出云为中心的三因地区早期铁砂提铁的可能性问题。这些问题的解决有望揭开出云及其周边地区古代历史上最大的谜团，即古代地方政权的面貌和特征。关于第一个问题的研究结果可以概括为两点：1)首要关注的问题是，三连地区是否真的生产了青铜器，特别是在小金谷遗址周围。在这方面，it…更多的证据不能证明它发生在弥生时期的出云地区；然而，据推测，青铜器至少在7至8世纪左右生产。2)研究证实，使现场生产成为可能的铜矿在萨宁地区，特别是岛根半岛富含铜矿，在那里，铜矿以更纯的原生铜形式存在。1)萨宁地区的铁生产始于公元6世纪下半叶。然而，它在这个阶段广泛传播是不可想象的，似乎是在7世纪以后，它才被广泛使用。2)早期铁生产的原料是铁砂。3)溶解铁砂的炉子呈箱形。4)这种铁的生产似乎在山上的基地周围很受欢迎。鸟取县的大森、中美泻湖和新知湖沿岸、大久出云地区以及GSno河中流周围。5)7世纪以后，铁的生产从早期到工具生产的过程大致完成，早期的铁原料似乎是从其他地方带来的，经过精炼后制成了餐具和兵器。在鸟取县岩石县的废墟中，发现了5世纪的精炼和锻造物品。对三宁地区古金属生产的研究正在逐步加快。较少

As for the ancient metal production (copper and iron) in the San'in districts, the following questions have been discussed and attracted much attention of citizens as well as scholars, i. e. ., the question as to where a large quantity of Yayoi bronze ware unearthed from the ruins of Kojindani in Hikawa-cho was produced, and the question concerning the possibility of iron production from iron sand from early periods in the San'in districts centering around ancient Izumo. It is expected that the solution of these questions might make clear the greatest mystery in the ancient history of Izumo and its peripheral regions rich in mythology and oral tradition, that is, the aspects and characteristics of local political power in ancient times.The results of the research concerning the first question can he summarized in two points : , 1) A matter of primary concern is whether bronze ware was really produced in the San'in 'districts, especially around the ruins of Kojindani. In this regard it … More could not be proved that it occurred in the Izumo districts in the Yayoi period ; however, the inference was made that bronze ware was produced at least around the 7th to 8th centuries. 2) The research confirmed that copper ore, which makes possible an on-the-spot production, is rich in the San'in districts, in particular in the Shimane Peninsula, where it occurs in a purer form as native copper.The results of the research regarding the second question. are the following : 1) The beginning of iron production in the San'in districts occurs in the latter half of the 6th century. However, it is unthinkable that it spread widely at this stage, and it seems to be after the 7th century that it, came into wide use. 2) The raw material of such iron production in the early stages was iron sand. 3) The furnace in which iron sand was dissolved is box-shaped. 4) This sort of iron production seems to have been popular around the base of Mt. Daisen in Tottori Prefecture, along the coasts of Nakaumi Lagoon and Lake Shinji, in the Oku Izumo districts, and around the middle courses of the GSno River. 5) It is after the 7th century that, the process of iron production from the early stages to the production of tools is roughly completed, and in earlier periods the raw material of iron seems to have been brought from other places and was refined to make cutlery and armory. Among the ruins of Iwayoshi in Tottori Prefecture, objects of refining and smithery from the 5th century were found. The research of ancient metal production in the San'in districts is gradually accelerating. Less
