Nobuyasu Okabayashi (岡林 信康, Okabayashi Nobuyasu, born on July 22, 1946, in Omihachiman, Japan) is a Japanese folk singer-songwriter. He has been called "Japan's Bob Dylan."
His childhood home was his father's church (established by William Merrell Vories, the founder of OMI Medical Supplies Corp). His current residence is Kameoka, Kyoto. Originally a Christian, he began to doubt his family's work with juvenile delinquents and searched for an escape. He threw himself into socialism, and after meeting folk singer Takashi Tomoya, he started to play guitar.
