Nichiren Buddhism, also known as Hokkeshū, is a branch of Mahayana Buddhism based on the teachings of the 13th-century Japanese Buddhist priest Nichiren (1222–1282) and is one of the Kamakura period schools. Its teachings derive from some 300–400 extant letters and treatises either authored by or attributed to Nichiren.
