It was established by Senge Takatomi (1845–1918), the 80th head priest of Izumo-taisha in 1882, as one of the original thirteen sects of Kyoha Shintō Rengokai (Association of Sectarian Shinto), during the Meiji era in Shimane Prefecture.

[4] During the Meiji Period, priests from Izumo Taisha were collected to participate in the creation of a centralized State Shinto.

For that reason, Senge Takatomi, the head priest of Izumo-taisha at the time, resigned from Izumo Taisha Omiya and founded Izumo-taishakyo.

The predecessor of Izumo-taishakyo was "Izumo Taisha Keijin-ko", which was established in 1873 by Senge Takatomi, to centralize Izumo-ko (an organization that uses Izumo-taisha as a religion shrine) throughout the country.

[6] By 1941, there were branches of Izumo Taishakyo operating in Hilo, Wailuku, Waipahu, Pearl City, Honouliuli, Ewa Lower Camp, Aiea, and Kakaako.

[9] Izumo-taishakyo holds Okuninushi as the head kami of the faith, as well as holding Ame no Hohi as an important kami, who is believed to be the ancestor of the Izumo clan from whom the founder of the faith, Senge Takatomi, as well as all heads of Izumo-taisha, are descended.

[11] Unlike the typical practice of Shrine Shinto, but in line with the practice of Konkokyo, a fellow Sect Shinto faith, during prayers, worshipers bow twice deeply with hands placed around the knees, then clap four times, instead of the more typical two, to gain the attention of the kami.
