What tatara means
Tatara is Japan's traditional method of smelting iron from iron sand with charcoal, and the works where this was done; it is also called tatara ironmaking. The Agency for Cultural Affairs' commentary on the Sugaya tatara settlement defines tatara as a general term for iron-sand smelting works, at whose centre stands the takadono, a tall hall housing the bellows. Iron sand and charcoal are fed in layers into a clay furnace while a strong blast of air is kept up to produce iron.
The word also refers to the large foot-operated bellows that blew air into a furnace, worked by treading a board up and down and also called fumi-tatara. It served not only for smelting but also for the furnaces that melted iron for casting. Articles should make clear from context whether the smelting works or the bellows is meant.
Reading the records
The Sugaya tatara settlement in Unnan, Shimane, an Important Tangible Folk Cultural Property, centres on a takadono with bellows and includes an office, rice store and workers' housing, preserving the sannai community of those who worked the tatara. According to the commentary, tatara were either mobile or fixed, Sugaya being of the fixed type.
The bellows sense appears in the casting town of Kawaguchi, Saitama, where a daruma bellows of the foot-tatara type that blew air into casting furnaces is designated a city cultural property. Some Kawaguchi foundries replaced foot-operated tatara with steam-driven blowers in the Meiji era.
