Hikoyai
was a member of a Japanese imperial clan from the Kojiki and other sources. He is one of the three princes born to Himetataraisuzu-hime on the banks of the Sakai River, and the eldest of the three. The name does not appear in the "Nihon Shoki" and there are no other names that are believed to be the same person. Hikoyai-no-Mikoto is the first son of Emperor Jimmu and Empress Himetataraisuzu-hime. His brothers are Kamuyaimimi and Emperor Suizei. After the death of Emperor Jimmu, Empress Himetataraisuzu-hime marries her stepson Tagishimimi, who would be considered a step-brother to Hikoyai-no-Mikoto and his brothers. Tagishimimi then attempts to assassinate the brothers, but instead is killed by Suizei who becomes the second emperor. Hikoyai-no-Mikoto does not have any significant role in the story and does not play an active role in the narrative. This is not uncommon in Japanese myths, where there are often brothers who do not play an active role in the story. Genealogy
