This picture of Nichiren Daishonin was painted in the 14th-15th Century, and is kept at the Nichiren Head Temple, Kuon-ji, in Yamanashi Prefecture, Japan. It is considered the most accurate picture of Nichiren extant. Nichiren (February 16, 1222 October 13, 1282) was a Buddhist monk who lived during the Kamakura period (1185-1333) in Japan. Nichiren taught devotion to the Lotus Sutra, entitled Myoho-Renge-Kyo in Japanese, as the exclusive means to attain enlightenment and the chanting of Namu-Myoho-Renge-Kyo as the essential practice of the teaching. Various schools with diverging interpretations of Nichiren's teachings comprise Nichiren Buddhism.
