In order to "reconstruct" the world, we need to return to our divine spiritual origins, hence the name of Oomoto, meaning "The Great Origin".

In Japan, returning to the origin means a return to the roots of Shinto, the ancient animistic faith which preceded Buddhism and is the indigenous faith of Japan.

Thus Oomoto takes its ritual and fundamental doctrine from Shinto and is known officially as a form of "Sectarian Shinto".
