Most of the present-day festivals are the rituals that were formalized based on the Taiho Code, the Jogan-gishiki (a set of books of ceremonial procedures compiled in the Jogan era), and the Engishiki (an ancient Japanese book of administrative regulations and ceremonial procedures that was completed in 927) in the Meiji period.
現在行われている祭祀の多くは明治時代に大宝令、貞観儀式、延喜式などを継承して再編されたものである。
