Endō Saemon-no-jō ［遠藤左衛門尉］ (n.d.): A lay follower of Nichiren. Little is known about him, though he appears to have been a samurai who lived on Sado, an island in the Sea of Japan. There is only one extant letter by Nichiren addressed to him, dated the twelfth day of the third month, 1274. In it, Nichiren conveys his deep gratitude for Endō’s assistance during his time of exile on Sado Island. According to one opinion, Endō was a relative of Abutsu-bō, another lay follower and a native of Sado who assisted Nichiren during his exile.
