The origin of Urahama Nenbutsu Kenbai is unknown, but has been handed down as a simple form of folk performing art amongst the locals in the Urahama area, due to its topographic isolation of Okirai in Sanriku Town.
It features masked dancers dancing to a nenbutsu hymn and burning incense, crouching middle section, and then swinging the sword like a stirring Asura in a fierce battle.
They are also active in next generation training programs for young adults and children.
