Nam Myōhō Renge Kyō (also, in some schools Namu Myōhō Renge Kyō; Devotion to the Law of the Lotus Flower Scripture) is a mantra that is chanted as the central practice of all forms of Nichiren Buddhism. The mantra is referred to as Daimoku (also, in some schools, O-daimoku) and was first revealed by the Japanese Buddhist teacher Nichiren on the 28th day of the fourth lunar month of AD 1253 at Kiyosumi-dera (also, Seichōji) near Kominato in current-day Chiba, Japan. The practice of chanting the daimoku is called shōdai. The purpose of chanting daimoku is to attain perfect and complete awakening (enlightenment).
