Nichiren Buddhism
Kenji was born into a family of Pure Land Buddhists, but in 1915 converted to Nichiren Buddhism upon reading the Lotus Sutra and being captivated by it. His conversion created a rift with his relatives, but he nevertheless became active in trying to spread the faith of the Lotus Sutra, walking the streets crying "Namu Myōhō Renge Kyō". In January 1921 he made several unsuccessful attempts to convert his family to Nichiren Buddhism.
