Sado-bo -- Niko Shonin Niko (1253-1314) was the son of a samurai from Mobara, Kazusa1. He was a novice priest at Mt. Hiei at the time his father met Nichiren DaiShonin in 12651. His father was so impressed by Nichiren that he had Niko brought back from Mt. Hiei in order to become a disciple of Nichiren Shonin. Niko was first named "Sado-bo" by Nichiren and it was by that nickname that he was known. He is closely associated with two other of Nichiren's disciples, "Hoki-bo" or Nikko Shonin and Sammi-bo. Sammi-bo later fell out with the Daishonin, and Niko later fell out with Nikko. Niko was junior to both in seniority. http://tinyurl.com/5bycs
