Kubo, the lay nun of ［窪尼］ (n.d.) ( Kubo-no-ama): A follower of Nichiren who lived in Suruga Province, Japan, during the thirteenth century. From the contents of the several letters Nichiren addressed to her, she appears to have been a sincere believer who frequently sent offerings to him. One explanation identifies the lay nun of Kubo with the wife of the lay priest Takahashi Rokurō Hyōe, and another with the lay nun Myōshin. The contents of the twelve letters Nichiren addressed to these three women, however, suggest that they were all the same woman. These letters suggest that the lay nun Myōshin was a member of the Yui family and the wife of the lay priest Takahashi. The same person was also an aunt of Nikkō, Nichiren’s successor. She became a lay nun and assumed the name Myōshin when her husband, the lay priest, was ill. In 1277, after his death, she went with her young daughter to live with the Yui family in a place called Kubo, from which the designation “the lay nun of Kubo” probably derives.
