Nichiren as the True Buddha of the Latter Day

Nichiren (1222 to 1282) himself made increasingly direct claims about his own religious status across his life's writings, moving from presenting himself as a devoted expounder of the Lotus Sutra toward statements, especially in letters written during and after his exiles, that identify his own person with the Buddha of the Latter Day of the Law, the degenerate final age Buddhist cosmology holds the historical Buddha's own teaching to be entering. Nichiren Shoshu, the school descending from Nichiren's disciple Nikko, developed this claim into settled doctrine through the systematic writings of the eighteenth century priest Nichikan, who argued from Nichiren's own letters, collected as the Gosho, that Nichiren was not merely a teacher expounding the Lotus Sutra's truth but the very Buddha the Lotus Sutra itself foretold would appear to save beings in the Latter Day, a status Nichikan's doctrine distinguishes from the historical Buddha Shakyamuni's own teaching authority, which Nichiren Shoshu doctrine holds to have already exhausted its saving power for the current age. The claim rests specifically on Nichiren's own writings rather than on later invention, though the school's most systematic doctrinal statement of it came generations after Nichiren's death, in Nichikan's formal argument for reading the Gosho's more suggestive passages as a direct, intended self-identification rather than as rhetorical emphasis.

The claim that Nichiren himself is the True Buddha of the Latter Day is not shared across all of the schools that trace their founding back to him. Nichiren Shu, the older and larger body of Nichiren descended temples, generally teaches that Nichiren was a bodhisattva and an extraordinary teacher who correctly identified the Lotus Sutra as the sole valid teaching for the current age, without elevating Nichiren's own person to the status of Buddha alongside or above Shakyamuni; Nichiren Shoshu's Buddha status claim, built on Nichikan's reading of the Gosho, is a specifically Nichiren Shoshu doctrinal position rather than a claim uniformly held across every school descended from Nichiren's teaching. The distinction matters for how each tradition treats its central object of devotion: Nichiren Shoshu doctrine holds that a particular mandala Nichiren himself inscribed carries unique authority as the object his own enlightenment as the True Buddha directly produced, a claim that depends on accepting Nichiren's Buddhahood in the first place, while schools that read Nichiren as an eminent teacher rather than a Buddha in his own right do not extend the same unique status to any single inscribed object. The disagreement traces to differing lineage claims about which of Nichiren's own disciples correctly transmitted his intended teaching, a dispute already underway among his direct students within years of his death.
