Its because Shintoism is just ancestor worship (like most forms of white/asian paganism), so it was kinda secularized from the start. Also interesting they had (((separation of Church and State))) forced on them at gunpoint, especially against their ancestor worship. Since most of the actual Christians in Japan were holocausted in Hiroshima and Nagasaki, its basically been in a limbo between Christianization and cultural Paganism. A lot of the innate Japanese psychology (specifically their value on responsibility, community, and self-sacrifice) would make them excellent Christians, but the jews have made sure they will never actually convert so long as ZOG is control of Japan by flooding their culture with the same consumerism and spiritual slop they used to destroy America's spirit.
