[5] He founded the Mokuyōkai [ja] (木曜会, The Thursday Association) a Japanese political faction dedicated to representing the interests of barons over higher nobility.

The descendants of Amenohohi-no-mikoto (天穂日命), the second son of Amaterasu-ōmikami (天照大御神), the sun goddess whose first son is the ancestor of the imperial family, have been, in the name of Izumo Kokuso (出雲国造) or governor of Izumo, taking over rituals because when Izumo-taisha was founded Amenohohi-no-mikoto rendered service to Okuninushi-no-kami.

The family's conflict around 1340 made them separated into two lineages, Senge (千家) and Kitajima (北島).

[6] Senge reorganized the traditions of Izumo Taisha under the organization Izumo-taishakyo and was instrumental in the development of Sect Shinto.

It was only in 1947 under the Allied Occupation of Japan that the Senge family managed to become high priests of Izumo Taisha again.
