Among common Nichiren Buddhists, the school is often referred to as the Minobu Sect due to their prominence within the Mount Minobu area. The school's Head Temple, Kuon-ji, is located on Mount Minobu where Nichiren lived in seclusion and where he asked to be buried. Another significant temple of Nichiren Shū is the Ikegami Honmon-ji'' where Nichiren died. Accordingly, many of Nichiren’s most important personal artifacts and writings preserved, also considered to be National Treasures of Japan are within their safekeeping.

The sect is also known for its more open and tolerant views of other Buddhist traditions, even mixing or incorporating various Buddhist beliefs and practices into their own Nichiren Buddhist aesthetics, most notably the use of religious statues, esoteric Buddhist magic rituals and the tolerant photography and distribution of the calligraphic Gohonzon.
