Ō clan

Ō clan (多氏) is a descendant clan of Jimmu and Himetataraisuzu-hime. They are descended from Kamuyaimimi.

Ō no Yasumaro was a famous member. He became head of the clan in 716 around the time he wrote the Kojiki.

Relationship with Takemikazuchi
Takemikazuchi was originally a local god (kunitsukami) revered by the Ō clan, and was a god of maritime travel. However, the Nakatomi clan who also has roots in this region, and when they took over control of priestly duties from the Ō clan, they also instituted Takemikazuchi as the Nakatomi clan's ujigami (clan deity). Or so this is the observation by in his Jinja to kodai ōken saishi (1989). He goes on to theorize that the Ō clan was originally ōmi (大忌), but was usurped by the Nakatomi who were among the "lesser priesthood" (the latter claims descent from the Inbe clan (忌部氏)).
