The school's head temple, Kuon-ji, is located on Mount Minobu where Nichiren lived in seclusion and where he asked to be buried.
Accordingly, many of Nichiren's most important personal artifacts and writings, also considered to be National Treasures of Japan, are within their safekeeping.
They include the Five Major Writings of Nichiren in which he establishes doctrine, belief, and practice, as well as many pastoral letters he wrote to his followers.
The sect does not reject the alleged oral transmissions (including the Ongi Kuden) citing "pastoral value" but cannot be definitively asserted as Nichiren's own teachings.
The sect upholds five kinds of practices: There are two type of practices expected of a believer: In addition, other popular forms of Buddhist silent meditation (Shōdai-gyō), singing of hymnal praises, the artistic copying of the Odaimoku (Shakyō), and the study of fundamental Buddhist concepts such as the Four Noble Truths, Threefold Training, Noble Eightfold Path and Taking Refuge taught by Shakyamuni Buddha are also used as supporting practices in the sect.
Presently, there are Nichiren Shū temples and Sanghas in the United States, Japan, Canada, Mexico, Costa Rica, much of South America, India, Korea, Southeast Asia (Indonesia, Malaysia, Singapore and Taiwan), and Europe.
