Various theories

Since the Wamyō Ruijushō is written as "Kikuchi", it is thought that Kikuchi-jibei dog is "Kikuchihiko" (Japanese) and is associated with Kumamoto Prefecture Kikuchi-gun.^[1]。^[2]^[3]^[4]
Since his name is written before Himikoko it is theorized he had the true power in Kununokuni
Some think that the derogatory meaning is removed from the official name.^[5] The word "狗" is fierce, and is thought to be "commitment (建, Takeru, タケル)," meaning a heroic and brave man. Kochi (古智)" means "old wisdom," but the opposite of "new (古い, Furui)" is "New (新しい, Atarashii)," and it is thought to be originally "New wisdom (新しい知恵, Atarashii Chie). The word "(卑狗)" is "Hiko," which is thought to be "Prince (彦)" or "High sun (日高)" or "Sun child (日子)".^[5]

Kukochihiko is a character in Fate/Grand Order. In it he is depicted as a villain who overthrew Himikoko and conquered Kununokuni, and attempted to conquer Yamatai.
