On the premise that, based on ancient classics such as "Kojiki" (The Records of Ancient Matters) and "Nihonshoki" (Chronicles of Japan), the Emperor ruled Japan as part of an unbroken imperial line, and that there were traditional strong connections between the Emperor at the center of the nation and the people, shrines all over the country were organized under the control of the Jingikan (Department of Divinities) and various institutions were established.
『古事記』『日本書紀』等の古典を根拠として万世一系の天皇が日本を統治すること、国家の中心に存在する天皇と国民との間に伝統的な強い紐帯があることを前提に、全国の神社は神祇官の元に組織化され、諸制度が整備された。
