Reproduction of Tatara Steelmaking using Kamakura iron sand as raw material and estimation of the origin area of raw iron sand

Abstract

In ancient Japan, steelmaking was practiced nationwide, but in the Middle Ages, steelmaking was carried out only in areas around Okuizumo, and steelmaking elsewhere declined. Kamakura was one of the areas that declined, but we reproduced ancient steelmaking using Kamakura Iron Sand as a raw material, and searched for a method to estimate the place of production of the iron that was used as the raw material for ancient generated iron.
