Tokimitsu was an infant when his father met Nichiren Daishonin and became a follower of his teaching. Upon the elder Nanjō’s death, Nichiren Daishonin traveled from Kamakura to Ueno Village to offer prayers for his repose. It was then, at age seven, that Tokimitsu is said to have first met Nichiren Daishonin.
In 1275 Nikkō, later Nichiren Daishonin’s designated successor, visited the grave of the late Nanjō Hyōe Shichirō on Nichiren Daishonin’s behalf; from that time on, Tokimitsu looked up to Nikkō as his teacher in the practice of Nichiren Daishonin’s teachings and aided him in propagating them.
Propagation proceeded energetically, especially in the Ueno and Atsuhara areas, and many people converted. Tokimitsu offered his residence for use as a center of propagation activities. As the number of converts, which included local priests and farmers, increased under Nikkō’s leadership, official and private opposition increased. During what came to be known as the Atsuhara Persecution, Tokimitsu used his influence to protect other believers, sheltering some in his home. Nichiren honored him for his courage and tireless efforts by calling him “Ueno the Worthy,” though he was only about twenty at the time.
In retaliation for Tokimitsu’s support of Nichiren and his followers, the shogunate levied exorbitant taxes upon him. Official pressure continued for several years, and the Nanjō family was forced to live in extreme poverty. Even under these circumstances, and while struggling to raise their nine sons and four daughters, Tokimitsu and his wife, Otozuru (also known as Myōren), consistently made offerings to Nichiren.
When Nichiren died on the thirteenth day of the tenth month, 1282, Nanjo Tokimitsu attended the funeral ceremony along with such long-time followers as Shijō Kingo, Toki Jōnin, the Ikegami brothers, and Ōta Jōmyō.
In 1289 Nikkō left Minobu and went to live at Tokimitsu’s residence in Ueno Village at the latter’s invitation. Tokimitsu donated to him the tract of land called Ōishigahara, on which a temple called Dai-bō was completed on the twelfth day of the tenth month, 1290.
