The products born from the beautiful nature and the feature of Chugoku district (iron sand, charcoal) naive natives’ idea and efforts both of which has been intermingled and has brought up the technique of ”TATARA”. The birth of the technique go up to the time of Izumo myth (about 2650 years ago) “The Sword of Amenomurakumo” which was swallowed in the tail of an eight-head snake, and the trend of the history and the culture of this district makes us slightly nostalgic.
"TATARA" is the technology of making iron in which iron sand and charcoal produced in Chugoku district are put into a furnace, are melted by blowing-in with “a balance bellows”. In feudal time, famous Japanese sword was produced by using this technique, which in farm villages farming equipments were produced, too.
The spirit of ”TATARA” along with the historical facts of the “TATARA” has long been told to our descendants and now lives in intent posture of casting technology.
