Various Artists - 決定盤日本民謡集 ふるさとの歌 (岩手篇)/Furusato No Uta - Iwate Edition, LP Vinyl Album (Folk, World and Country, Min'yō, Field Recording) [1968]

Pretty curious Japanese min'yō (folk songs, primary from rural agricultural areas) compilation from series called "Furusato no uta" (homeland/hometown songs). This edition is dedicated to folklore heritage of Iwate Prefecture. Looks like my copy has authentic 1968 shrink package.
