Step-by-step explanation:
The Nichiren Shu sect is a branch of Buddhism that originated in Japan during the Kamakura period (1185–1333). It was founded by the Japanese Buddhist priest Nichiren Daishonin, who emphasized the Lotus Sutra as the supreme Buddhist teaching and believed it holds the key to enlightenment. This sect is distinctive for its focus on chanting the phrase Nam-myoho-renge-kyo and its belief in the Lotus Sutra as the sole path to enlightenment. Nichiren Shu followers also practice various other forms of devotion that were shaped by the environment in Japan where both Shintoism and Buddhism have been influential religious traditions.
