Daisaku Ikeda was a Japanese Buddhist leader, author, philosopher and educator. He served as the third president and then honorary president of the Soka Gakkai, the largest of Japan's new religious movements.

Soka Gakkai is a Japanese Buddhist religious movement based on the teachings of the 13th-century Japanese priest Nichiren as taught by its first three presidents Tsunesaburō Makiguchi, Jōsei Toda, and Daisaku Ikeda. It is the largest of the Japanese new religions and claims the largest membership among Nichiren Buddhist groups. The organization bases its teachings on Nichiren's interpretation of the Lotus Sutra and places chanting Nam Myōhō Renge Kyō at the center of devotional practice. The organization promotes its goals as supporting "peace, culture, and education".
