Hikoyai
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."
