Kempon Hokke

In 1898, Myomanji-ha incorporated as the Kempon Hokke school and Honda Nissho (1867–1931) was appointed its first head administrator.

Much of Kempon Hokke's underlying teachings are extensions of Tendai (天台, Cn: Tiantai) thought.

They include much of its worldview and its rationale for criticism of Buddhist schools that do not acknowledge the Lotus Sutra to be Buddhism's highest teaching, as stated by Buddha Shakyamuni.

For example, Kempon Hokke doctrine extends Tendai's classification of the Buddhist sutras into five time periods and eight categories (五時八教, goji-hakkyō), its theory of 3,000 interpenetrating realms within a single life-moment (一念三千, Ichinen Sanzen), and its view of the Three Truths (三諦, Santai).

Nichiren Shu was insisting that the Eternal Buddha as the truth of universe is Namu Myoho Renge Kyo Tathagata.
