Nasu no Sukemura

Nasu no Sukemura was a Kamakura-period warrior and the sixth head of the Nasu clan of Shimotsuke, son of Mitsusuke. He embraced Pure Land nenbutsu, became a disciple of the monk Shinran under the clerical name Shinganbō Kyōnen, and in 1223 founded Jigan-ji.

Genealogies credit him with a life of seventy-eight years. A modern theory holds instead that he never held the headship, which passed to his uncle Sukenaga's Iōno line and was recovered only under his son Sukeie.
