Hikoyai-no-Mikoto was a member of a Japanese imperial family according to the Kojiki.. He was the eldest of three princes born to Empress Himetataraisuzu-hime on the banks of the Sakai River.

After Jimmu died, Empress Himetataraisuzu-hime married Tagishimimi, her stepson. Tagishimimi tried to kill the brothers but was instead killed by Suizei, who became the second emperor. Hikoyai-no-Mikoto did not have an active role in the story and did not play a significant part in the narrative. This is common in Japanese mythology where some brothers do not play a major role.

According to the Kojiki, Hikoyai-no-Mikoto was the son of Jimmu, who was the first emperor of Japan, and Himetataraisuzu-hime, the daughter of Omononushi no Mikoto.

However, Hikoyai-no-Mikoto's name is not mentioned in the Nihon Shoki. In other sources, such as the Shinsen Seijiroku, the Ibarada-ren article of the Ukyo Emperor, and the "Aso Family Brief Genealogical Record," there is a different theory that suggests he is the son of Kamiyai-mimi-no-mikoto. Interestingly, Hikoyai-mikoto's name does not appear in the "Aso Genealogy" or the "Monzan Genealogy" found in the 16th volume of the "Shoshu Keifu."

The "Shinsen Shōjiroku" commissioned by Emperor Saga and the "Aso Genealogy (阿蘇家略系譜, Aso-ka ryaku keifu)" have a different theory that suggests Hikoyai was the son of Kamuyaimimi, as opposed to the previously mentioned belief that he was the son of Himetataraisuzu-hime and Jimmu.
