Nichiren Buddhism: The Lotus Sutra and the Daimoku

By Tim Yu · Updated 2026-06-04

Nichiren Buddhism is a school of Japanese Mahāyāna Buddhism founded in the 13th century by the monk Nichiren — and it is unlike any other. Where most traditions offer a broad menu of practices, Nichiren staked everything on a single text and a single act: the conviction that the Lotus Sūtra is the Buddha’s ultimate teaching, and that chanting its title — Nam-myoho-renge-kyo — is the complete path to awakening for our age. Through modern movements like Soka Gakkai, it has become one of the most widespread forms of Buddhism in the world.

Nichiren the Reformer

Nichiren (1222–1282) was born to a humble fishing family in Japan and trained as a monk in the Tendai school, the great establishment tradition centred on the Lotus Sūtra. But he grew convinced that Japanese Buddhism had betrayed its own heart: chasing esoteric rituals, Pure Land devotion, and Zen while neglecting the Lotus Sūtra that Tendai itself held supreme.

He responded with the fire of a prophet. Proclaiming the Lotus Sūtra as the one true teaching for the age, he denounced the rival schools in the bluntest terms and warned that Japan’s calamities — famine, plague, the threat of Mongol invasion — were the fruit of abandoning the true Dharma. This made him powerful enemies. He was persecuted, exiled more than once, and at one point narrowly escaped execution. Through it all his conviction never wavered, and he gathered devoted disciples who carried his teaching forward.

One Sutra Above All

The foundation of everything Nichiren taught is the supremacy of the Lotus Sūtra. He accepted the traditional view that the Buddha had taught at different levels for different audiences, but argued that the Lotus Sūtra was his final and complete revelation — the teaching in which all the others find their fulfilment, and the only one fully suited to the present, degenerate age (mappō, the “latter day of the Dharma”).

Crucially, Nichiren held that in this age, the essence of that vast sūtra is concentrated in its title. To embrace the title with faith, he taught, is to embrace the whole — and to receive the Lotus Sūtra’s central promise: that Buddhahood is open to every being, here and now.

The Daimoku: Nam-myoho-renge-kyo

This is why the central practice of Nichiren Buddhism is so strikingly simple. It is the chanting of the daimoku (“title”):

Nam-myoho-renge-kyo — Namu Myōhō Renge Kyō.

Myōhō Renge Kyō is the Japanese title of the Lotus Sūtra (“the Sūtra of the Lotus of the Wonderful Dharma”); Namu means devotion or homage. So the phrase means, roughly, “Devotion to the Mystic Law of the Lotus Sūtra.” Nichiren taught that chanting it with faith is not a mere preliminary but the complete practice — containing the entire merit of the sūtra and awakening one’s own innate Buddhahood. Practitioners chant it, often for sustained periods, before the Gohonzon — a sacred mandala, first inscribed by Nichiren, that depicts the title of the sūtra ringed by the buddhas and bodhisattvas of its great assembly.

Nichiren Buddhism Today

After Nichiren’s death his followers divided into several lineages, and the tradition today is carried by a number of schools. The largest and most traditional temple schools are Nichiren Shū and Nichiren Shōshū. But the form best known outside Asia is Soka Gakkai International (SGI) — a 20th-century lay movement, now one of the largest and most international Buddhist organisations in the world. Lay-led and socially engaged, SGI emphasises chanting Nam-myoho-renge-kyo for personal transformation, human happiness, and world peace, and it has done much to bring Nichiren’s once-fiercely-Japanese teaching to a global audience.

A Distinctive Path

Nichiren Buddhism can look surprising beside the meditative calm we often associate with the tradition — it is devotional, confident, sometimes confrontational, and centred on faith and chanting rather than silent sitting. But it springs from a recognisably Buddhist root: the Lotus Sūtra’s radical promise that awakening belongs to everyone, and the conviction that there is a practice simple enough for anyone to walk that path. It is one of the genuine faces of Mahāyāna Buddhism.
