Chas stated on Alternate Religion Buddhism of Nichiren that the following passage that I provided was a forgery designed by the orthodox sects:
"When I was in the Province of Sado between mountains and wilds far away from a village was a samadhi place called Tsukahara. There was a hall with a single room and four walls in that place. On the roof the boards did not meet and all four walls were ruined. In the rain it was like being outside and the snow piled up inside. There was no Buddha [image]. Neither was there a single reed tatami mat. However, I set up the statue of the Master of Teachings Lord Shakya which I kept from the beginning and grasped the Hokekyo in my hand, put on a straw raincoat and held up an umbrella, yet for four years nary a person appeared to give me food." -- Reply to the Bhikshuni Myoho", STN, v. 2, 15
Then I showed him from whence it came in the SGI writings of Nichiren Daishonin:
"When I was in the province of Sado, I lived in a graveyard called Tsukahara, at a place between the meadows and the mountains that was far removed from human habitation. I lived in a small hut built with four posts. The roof boards did not shut out the sky, and the walls were crumbling. Rain came in as though there were no roof at all, and the snow piled up inside. There was no image of the Buddha, and no trace of matting or other floor covering. But I set up the figure of Shakyamuni, the lord of teachings, that I have carried with me from times past, and held the Lotus Sutra in my hand, and with a straw coat around me and a straw hat on my head, I managed to live there. Four years passed, during which no one came to visit and no one brought me food. I was like Su Wu, held captive for nineteen years in the land of the northern barbarians, wearing a straw coat and eating snow."
