Both its leadership and adherents claim that only their practice is "The True Buddhism" and ascribe the honorific title to Nichiren, as the "Sacred Original "True" Buddha" (御本仏, Go-Honbutsu) and the Dai-Shonin (大聖人, "Great Holy Teacher") while maintaining that the sole legitimate successor to both his ministry and legacy is Nikko Shonin and the successive high priests of the sect, led by the current 68th High Priest, Hayase Myo-e Ajari Nichinyo Shonin, who ascended to the position on 15 December 2005.

[citation needed] By the imperial Daijō-kan Decree #133 of the Emperor Meiji since 1872, Nichiren Shōshū priests, like other Japanese Buddhist sects as well as other former traditionalist "celibate" lifestyles such as artisans and Geisha et cetera, have been permitted to marry.

Accordingly, the sect does not impose any regulations of Buddhist morality on gender or marital relationships, poverty or wealthy lifestyles, ranging from personal habits or vices, divorce, abortion, sartorial or dietary choices including the consumption of vegetables versus meat, dairy or alcohol, et cetera.

The sect also vehemently rejects monetary and material donations from non-members who are not registered or affiliated with a local branch temple, citing claims of "karmic impurity" from non-believers and those who belong to other religions.

Accordingly, the offertory fee to register as a new member is strongly forbidden to be paid for by a fellow Hokkeko believer, except under rare circumstances of extreme poverty or dire homelessness.

Another symbol is the eight-spoked wheel of the Noble Eightfold Path called Rimbo (Treasure Ring) as well as the tortoise crest for Nikko Shonin, who is considered by the school to be the sole and legitimate successor to Nichiren.

These willed rebirths include humans, animals and other life forms (and vice versa) that choose to be reborn in whatever capacity to advance the Buddhist enlightenment of Nam-Myoho-Renge-Kyo in the universe.

In addition, the school claims that Nichiren was fulfilling an eschatological prophecy made by Shakyamuni Buddha in Chapter 21 of the Lotus Sutra regarding the Three Ages of Buddhism which states:[citation needed] "…Like the rays of the sun and the moon that dispel the darkness of phenomena, this person will practice in the world, dispel the darkness of all humanity and lead immeasurable numbers of bodhisattvas to finally attain the One Vehicle" – Chapter 21: The Mystical Powers of Tathagata Buddha.

[citation needed] Accordingly, the sect teaches that the Three Jewels of Buddhism are a single, inseparable entity that equally share the internal enlightenment of Nichiren.

On the other hand, Shakyamuni declares in the Essential Teachings (Chapters 15–28) that his enlightenment in India was only temporary, and that he in fact already attained Buddhahood in a mysterious, timeless point in the Universe.

Rather, this secret was revealed in Chapter 16 of the Lotus Sutra by Ākāśagarbha ("Heavenly Jewel") Bodhisattva to Nichiren and his latter claim to the expressed public recitation of Nam-Myoho-Renge-Kyo through an alleged deeper understanding of the text.

[citation needed] Nichiren Shoshu claims this tradition from the Chapter 21 of the Lotus Sutra where Shakyamuni Buddha passes his vow to the Visistacaritra Bodhisattva and his "infinite followers" along with the merits of the Seven Jewels of the Treasure Tower.

[citation needed] The sect teaches that personal enlightenment can be achieved in one's present life form existence (即身成仏, Sokushin Jobutsu).

Accordingly, the sect maintains that only by chanting these words to their object of worship (Jp, Hon–zon) that a human person (the minimal level of existence, and excluding animals, insects or insentient beings) is believed to change or eradicate the accumulation of negative karma and ultimately achieve both happiness and enlightenment.

This stems from their belief that it is composed of Nam and the Japanese title of the Lotus Sutra, Myōhō-Renge-Kyō, as revealed by the founder Nichiren for widespread propagation consisting of the following components (termed "Powers of the Mystic Law"): This four-part combination of physical practice and religious faith are claimed to eradicate negative forms of karma, attract positive new karma and transcend to a happier and higher life status.

Furthermore, it teaches that this secret was revealed by the Buddhist god Ākāśagarbha at a large open garden during the training years of Nichiren prior to his attempted execution and revelation of enlightenment at Shichirigahama beach.

The Dai Gohonzon (also called: Dai-Gohonzon of the High Sanctuary of Essential Teachings) is a calligraphic mandala inscribed with Sanskrit and Chinese characters on a plank of Japanese camphorwood as the only object of worship by believers.

[citation needed] The sect claims the ninpō-ikka or "Unity of the Person and the Buddhist Dharma" as one entity and the Dai Gohonzon is revered as the personification of Nichiren himself.

[citation needed] The Dai Gohonzon is enshrined at the Hoando worship hall [11] within the Taiseki-ji Grand Main Temple complex grounds at the foot of Mount Fuji.

The temple priesthood will only expose the image for constant public veneration once the conversion of the Emperor of Japan and Kosen-rufu is achieved, maintaining the beliefs of Nichiren Shōshū as the primary religion in the world by Japanese imperial decree.

[citation needed] The group was known for being brazen in confronting Soka Gakkai and former High Priest Nittatsu Shonin, resulting in a lawsuit against him amidst public protest.

[citation needed] At the time, Soka Gakkai supported Nikken's claim to be the rightful successor of Nittatsu Hosoi as high priest.

Also, Nichiren Shoshu denounced "a whole series of scandals and anti-social behavior, such as the obstacle to certain publications or the affair of listening to the telephone conversations of the honorary president of the PC.

[21] The donations, while voluntary, are granted for Toba memorial tablets, Kakocho ancestral books and the overwhelming Japanese conservative customs and mannerisms associated with Buddhist practice.
