Emperor Tenji
His mother was Princess Ōta whose father was Emperor Tenji. He was therefore the younger full-blood brother of Princess Ōku. His consort was Princess Yamanobe, daughter of Emperor Tenji, thus his cousin. His life is known from the "Nihon Shoki", and his personality emerges through such poetry anthologies as "Kaifūsō" and "Man'yōshū".
