Scholars, such as Sakamoto Koremaru, argue that the "State Shinto" system existed only between 1900 and 1945, corresponding to the state's creation of the Bureau of Shrines. That bureau distinguished Shinto from religions managed by the Bureau of Shrines and Temples, which became the Bureau of Religions. Separated through this state bureaucracy, Shinto was distinguished from Buddhist temples and Christian churches, which were formulated as religious. This marked the start of the state's official designation of Shinto shrines as "suprareligious" or "non-religious".
