The Official Oomoto Homepage: Oomoto (大本, Ōmoto, Great Source, or Great Origin), also known as Oomoto-kyo (大本教, Ōmoto-kyō), is a religion founded in 1892 by Deguchi Nao (1836–1918), often categorised as a new Japanese religion originated from Shinto. The movement's spiritual leaders have always been women within the Deguchi family; however, Deguchi Onisaburō (1871–1948) has been considered an important figure in Omoto as a seishi (spiritual teacher). Since 2001, the movement has been guided by its fifth leader, Kurenai Deguchi.
