Further, there is another theory about the appointment of Zesan stating that it was not when Kitano-jinja Shrine was constructed, but that he was appointed as head priest when Emperor Ichijo made Gyoko (Emperor's visit) to Kitano-jinja Shrine (in 1004).
なお、是算の別当任命については、北野神社創建時ではなく、寛弘元年（1004年）、一条天皇の北野神社行幸時のこととする別説もある。
