一、前言有关北九州地区古代冶铁生产的遗址有福岗县系岛郡志摩町八熊的冶铁遗址(图一)和该郡二丈町琢田的精练锻冶(大锻冶)遗址(图二)等。经过发掘调查能够确定的时代为古喷时代后期至奈良时代后期。大泽正已氏认为,从古坟时随葬品的铁滓分析来看,日本的砂铁精炼始于五世纪后叶,盛行于六世纪后叶。日本的冶铁精炼,从须惠器窑和木炭窑等制窑技术的外来输入的时间考虑,似以五世纪中叶为妥。 I. Preface The sites related to the ancient smelting of iron in Kitakyushu are the ruins (Figure 1) of the eight bears in Shima-cho, Shimane-gun, Fukushima Prefecture and the site of scouring (large forging) Wait. After excavation survey can determine the era of the ancient jet era to the late Nara period. Ozawa is already that, from the burial goods at the time of the ancient tomb analysis of ironclad, Japan’s sand iron refining began in the fifth century later, popular in the sixth century leaves. Japan’s smelting of iron, considered from the time it was imported from kiln-kiln technologies such as the beneficiary kiln and charcoal kiln, seemed to be appropriate by the middle of the fifth century.
