Emperor Kōnin
Records from the reign of Emperor Heizei (806-809) mention that "Kamo-mioya jinja" was amongst a select number of establishments which had been granted a divine seal for use on documents. The seal would have been enshrined in its own unique "mikoshi" ("Oshite jinja"). This granting of a special seal and the practices associated with its use and preservation conformed to a pattern established by Emperor Kōnin (770–781) in 778 ("Hōki 9").
