«無宗教
mushūkyō, "no religion", in Japanese language and mindset identifies those people who do not belong to organised religion. To the Japanese, the term "religion" or "faith" means organised religions on the model of Christianity, that is a religion with specific doctrines and requirement for church membership. So, when asked "what is their religion", most of the Japanese answer that they "do not belong to any religion". According to
NHK studies, those Japanese who identify with
mushūkyō and therefore do not belong to any organised religion, actually take part in the folk ritual dimension of
Shinto. Ama Toshimaru in
Nihonjin wa naze mushukyo na no ka ("Why are the Japanese non-religious?") of 1996, explains that people who do not belong to organised religions but regularly pray and make offerings to ancestors and protective deities at private altars or Shinto shrines will identify themselves as
mushukyo. Ama designates "natural religion" what NHK studies define as "folk religion", and other scholars have named "Nipponism" (
Nipponkyō) or "common religion".»
