Reconstruction of iron technology and diffusion in Tohoku and Hokkaido

报告共分五章。第一章介绍了本课题的研究目的和研究方法。在东北和北海道进行了包括自然环境研究在内的区域考察。铁技术已集中在该项目中，以调查两个地区的文化接触。在研究过程中，寻找遗址是一个困难的过程，需要挖掘。萨摩文文化中的居住坑群位于沿着北海道海岸线。因此，调查集中在北海道十胜区太平洋一侧的海岸线沿着。经过调查等调查，本次研究选择了霍罗卡延托湖附近的滨台木2号遗址进行发掘。在一个居民坑处挖了战壕。在东北地区，位于津轻地区九三湖附近的岩城河口的Karakawajoato现场的炼铁炉 ...更多信息 已经被挖掘出来了。在这一地区，特别是在岩城山的山脚下，发现了许多铁炉，这表明该地区可以成为铁生产中心。这是研究铁矿生产技术及其分布的一个重要领域。第二章论述了滨台木2号遗址的发掘情况。虽然挖掘工作尚未完全完成，但结果显示，该遗址表明了更北部的文化联系，如千岛群岛和东北地区的文化。这需要进一步调查。第三章讨论了卡拉卡瓦约托遗址的发掘结果。由于炉缸的结构，此处的炉缸可解释为精炼炉缸而非生产炉缸。可以认为，空气脱碳过程发生在炉膛内部。第4章介绍了从网站的材料分析结果，根据考古学分析（必要的识别过程中使用的铁技术）进行了讨论。第五章介绍了活性炭分析的分析结果。少

The report consists of 5 chapters. The contents of the chapters are summarized below.Chapter 1 discusses the aim of the project and the way in which the investigation carried out. Examination of area, including the research of natural environment took place both Tohoku and Hokkaido. The iron technology has been centralized in the project in order to investigate cultural contact with in both areas. Finding sites, which need to be excavated was difficult process during the research. The group of dwelling pits in Satsumon culture is located along the coastal line of Hokkaido. So investigations focus on the coastline along the Pacific Ocean side of Tokachi district in Hokkaido. After some investigations such as surveying, Hamataiki 2 site near Lake Horokayanto is chosen to excavate for this study. The trenches have been dug at one dwelling pit. In Tohoku district, the hearth of iron production at Karakawajoato site located on the mouth of River Iwaki near Lake Jiusanko in Tsugaru district … More has been excavated. In this area, particularly around the foothills of Mount Iwaki, many iron hearths have been found suggesting that the area can be a center of iron production. It is an important area in order to investigate the iron production technique and its distributions. Chapter 2 discusses the excavation of Hamataiki 2 site. Although the excavation has not completely finished, results show that the site indicates some cultural contact further north such as culture in the Kuril Islands as well as in Tohoku. It need to investigate further more. Chapter 3 discusses the results of excavation at Karakawajoato site. The hearth at this site can be interpreted as refining hearth rather than production hearth due to the structure of the hearth. It is possible to consider that the decarburisation process by air had taken place inside of the hearth. Chapter 4 describes that the analytical results of material from the site, based on archaeometallurgical analyses (essential to the recognition of the process used in iron technology) are discussed. Chapter 5 describes the analytical results of charcoal analysis. Less
