ototakaranoiratsume

Oto-takara (弟財郎女) was the wife of Emperor Seimu, and the mother of Prince Wakanuke, who is presumed to have died young. Because she was not of imperial descent, Oto-takara was not given the title Kōgō, thus not counting her as an Empress Consort. Ultimately, in 192 this came to pass and Emperor Chūai was enthroned. Due to her not producing any more children, her husband became the last direct descendent from Emperor Jimmu, and was the first split branch; others later followed.
