Nichiren was a slanderer according to the teachings of the Nichiren Shoshu and the Soka Gakkai

"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."
