Sassa, Mitsuaki.  “A Study of the Prewar Unification Movement between the  Ōmoto-kyo and the World Red Swastika Society Religions."Journal of New Religions, (October 2006): 33-55.

Abstract

A unification movement to integrate various religions and already developed in prewar East Asia. This was marked by the merging of Ōmoto-kyo in Japan and the World Red Swastika Society in China, both of which had rapidly grown at the beginning of the 20^th century. In 1923, the two religious groups shared mutually similar doctrines and affiliations. Until about 1935, the two had formed such an intimate bond in their movement that “Both as One” became their catchphrase. The cooperation of these two groups inspired the May, 1925 World Religious Federation meeting in Beijing. In this federation, leaders of various worldwide religions gathered together and appealed for the integration of religions for global peace.

In this study, I will focus on the affiliation between  Ōmoto-kyo and the World Red Swastika Society. I will also analyze the characteristics and limits of this religious union movement in an age when Imperial Japan invaded continental Asia. Finally in this report I will consider the contemporary meaning of and the future possibility for the kind of religious unification movement developed among prewar Asians new religions.
