Oomoto , also known as Oomoto-kyo , is a religion founded in 1892 by Deguchi Nao (1836–1918), often categorised as a new Japanese religion originated from Shinto. The spiritual leaders of the movement have always been women within the Deguchi family; however, Deguchi Onisaburō (1871–1948) has been considered an important figure in Omoto as a seishi. Since 2001, the movement has been guided by its fifth leader, Kurenai Deguchi.

Kokutai is a concept in the Japanese language translatable as "system of government", "sovereignty", "national identity, essence and character", "national polity; body politic; national entity; basis for the Emperor's sovereignty; Japanese constitution" or nation.
