2019/08/12· I went on to visit some of the original iron sand-rich metalmaking villages of Shimane prefecture. Before the introduction of western steelmaking, Shimane prefecture was a central production hub of Japanese steel, called watetsu, using a process referred to as tatara-buki. The clay furnaces in which the steel is smelted and the sites that …
