The Jinmyocho (list of deities) in the Engishiki (codes and procedures on national rites and prayers) list most shrines by name only, showing that Saijin of most shrines were not specifically named until around the early 10th century, when the Engishiki was compiled.
延喜式神名帳でもほとんどの神社は社名しか記されていないことから、延喜式が編まれた10世紀初頭ごろまではほとんどの神社の祭神には特に名前がついていなかったことがわかる。
