Nichiren Shōshū (日蓮正宗 English: Orthodox School of Nichiren?) is a branch of Nichiren Buddhism based on the teachings of the 13th-century Japanese Buddhist priest Nichiren Daishonin (1222–1282). Nichiren Shōshū claims Nichiren as its founder through his disciple Nikkō (1246–1333), the founder of the school's Head Temple Taiseki-ji, located at the base of Mount Fuji. It has adherents throughout the world, with the largest concentrations in Japan,Taiwan, South Korea, Sri Lanka, Singapore, Malaysia, Thailand, Indonesia, Hong Kong, Ghana, the Philippines, Europe, and North, Central, and South America, while its main headquarters in the United States is located in West Hollywood. Its vowed lay members are called the Hokkeko (法華講衆).
The official crest symbol used by the sect is the Japanese Tsuru crane bird while its main object of veneration is the Dai Gohonzon, presently enshrined in Hoando building located in Fujinomiya, Shizuoka Prefecture. In addition, both its leadership and faithful ascribes a uniquely honorific title to Nichiren, as the Dai-Shonin (Great Teacher) while maintaining that the sole legitimate successor to both his ministry and legacy is Nikko Shonin alone and his successive high priests. Both male and female priesthood exists in Nichiren Shoshu.
