Okuizumo Tatara and Sword Museum
The Okuizumo Tatara and Sword Museum presents the history of tatara ironmaking and the ongoing practice of traditional swordsmithing. Okuizumo is the only place where the tatara smelting method is still practiced, and this museum is one of several facilities dedicated to the region’s ironmaking heritage.
The tatara method of ironmaking is unique to Japan and dates to the latter half of the sixth century. A charcoal-fed clay furnace is used to smelt iron sand over the course of several days, producing a multi-ton mass of iron, slag, and steel called a “bloom.” This method is the only way to produce tamahagane steel, which is prized by Japanese swordsmiths.
The exhibits in the first half of the museum introduce the rise and eventual decline of the tatara method. The museum’s second half focuses on contemporary efforts to revive tatara smelting to create steel for modern swordsmiths. Tatara ironmaking was more than a production method; it was also an industry that shaped the cultures of Okuizumo and the broader San’in region (Shimane and Tottori Prefectures).
