Mahikari is a Japanese new religious movement (shinshūkyō), with a number of variants or offshoots. Founded in 1963 by Yoshikazu Okada (岡田 良一) (1901–1974), the name "Mahikari" means "true light" in Japanese, being a compilation of the words "ma" (真 – true) and "hikari" (光 – light).
Mahikari derived its cosmology and values from another Japanese new religion, Sekai Kyuseikyo, which in turn was strongly influenced by Oomoto-kyo, one of the oldest "new religions" of Japan. Each of these "new religions" contain elements of Shintoism (the emphasis on purity, the reference to gods, and the veneration of the emperor), Buddhism (belief in karma and reincarnation), and shamanism (the divine status of the leader, miraculous healing, etc.)
Okada claimed that he experienced a revelation on February 22, 1959; while suffering a high fever, he was transported to the world of divine spirits and saw a god with white hair standing on a beautiful white cloud, washing clothes in a golden tub. "Later Okada would tell his followers that this experience was a revelation from God concerning his future mission of cleansing the world and human kind." To support this mission, Okada founded a religious corporation called "L.H. Yokoshi Tomo no Kai" (陽光子友乃会 – Company of Sun Light Children) and started recruiting followers. In 1963, he registered this group under the name "Sekai Mahikari Bunmei Kyodan" (World Divine Light Organization).
Okada claimed he received revelations from a deity he called Mioya Motosu Mahikari Omikami ("Original Parent, Lord, God of True Light" – 御親元主真光御み神 ), or Su ("Lord" – 主) God for short. He maintained that this god was the supreme creator of everything. Okada's role was to inaugurate a new era as a heralding messiah (sukuinushi) for this god and to introduce Mahikari no Waza, a method of channelling a 'divine' invisible energy, or true light ("mahikari" – 真光), which could eliminate the causes of illness, poverty, and strife from the world.
