Shintoists of the Hirata-ha school, who sympathized with Atsutane HIRATA's way of thinking, and scholars of Japanese classical literature from Tsuwano Domain proposed that the spirit of the Meiji Restoration should be based on the spirit of Emperor Jimmu and the restoration of imperial rule should make modern Japan a country of 'saisei icchi' (unity of religion and state) and the declaration of the restoration of imperial rule contains the phrases "restoration of imperial rule" and "Emperor Jimmu"; the restoration of imperial rule and 'doing everything as in the time of Emperor Jimmu,' which until then had been advocated as ideals, became reality when building an actual country and took on public significance with the slogan of 'renewal of everything.'
平田篤胤の思想に共鳴した平田派の神道家たち、また津和野藩出身の国学者たちは明治維新の精神を神武天皇の精神に基くものとし、近代日本を王政復古による祭政一致の国家とすることを提唱していたが、王政復古の大号令には王政復古と神武天皇の語が見え、従来理想として唱えられていた王政復古と「諸事神武創業ノ始ニ原」くことが、実際の国家創生に際して現実性を帯び、「万機御一新」のスローガンとして公的な意義を持つようになったのであった。
