Nichiren Buddhism is a form of Japanese Buddhism that emphasizes repeated recitation of the mantra namu myoho renge kyo ("salutation to the Lotus Sutra") for health, happiness and enlightenment. Nichiren Buddhists believe it is possible to attain enlightenment in a single lifetime through practice of "True Buddhism" (i.e., Nichiren). Nichiren Buddhism has divided into several branches, the largest of which are Nichiren Shu, Nichiren Shoshu, and Soka Gokkai International.
