Gen-Ko a Buddhist monk, was born at Sak-Syou about A.D. 1132. He introduced a new Buddhist doctrine into Japan, which soon attracted a great number of disciples. A woman of the court of the mikado was converted to this religion, which circumstance provoked great excitement, and a sentiment of hatred, mingled with- an impetuous desire for vengeance in the heart of the mikado. Gen-Ko was banished, one of his most ardent disciples put to death, and others persecuted; He died A.D. 1212. See Hoefer, Nouv. Biog. Generale, s.v.
