Hirakawachi Itchōme (Japanese: 平川地一丁目) is a former Japanese folk music group consisting of brothers Ryūnosuke Hayashi (born April 14, 1988) and Naojirō Hayashi (born December 23, 1990). Their name is more often romanized as Hirakawachi 1-chome. Their name is actually a reference to where they were originally from in Shizuoka Prefecture, and references the Japanese addressing system. 1-chome is like "first district".
