In the early 13th century (the early Kamakura period), Emperor Juntoku wrote in "Kinpisho" (the book which recorded the history and origin of Imperial Court ceremonies, and which set forth the rules and etiquette for carrying out such ceremonies) that Kinen-sai festival was the ritual related to Ise-jingu Shrine.
13世紀初め、鎌倉時代初頭の順徳天皇の『禁秘抄』では、祈年祭は伊勢神宮関係の祭祀であると明記されている。
