Iwase Province (石背国, Iwase no Kuni) is an old province of Japan which existed for a brief period of time in the Nara period in what is now western Fukushima Prefecture.[1]
History
Iwase Province was created during the reign of Empress Genshō.[2] The Yōrō Ritsuryo established the Iwase Province in 718 through the division of the Michinoku Province (Mutsu Province). It was composed of five districts, named Shirakawa (白河), Iwase (石背), Aizu (会津), Asaka (安積) and Shinobu (信夫).
The area encompassed by the province reverted to Mutsu at some point between 722 and 724. Some scholars have suggested that this may have been motivated by economic considerations.[2]
