Life
Niigasa was a daughter of Yamato no Ototsugu (和乙継) who was a descendant of Prince Junda (c. 480–513). Prince Junda, the second son of King Muryeong of Baekje, was born in Japan and eventually became the ancestor of later known to be Yamato clan. Her mother was known to be Haji no Sukune Maimo (土師宿禰 真妹), whose surname is later, also known be Oe no Asomi (大枝朝臣). She became a concubine of Prince Shirakabe, grandson of Emperor Tenji, and bore Prince Yamabe in 737 and Prince Sawara in 750. Prince Shirakabe was married to Princess Inoe, a daughter of Emperor Shōmu in 744. When Empress Kōken died in 770, Shirakabe was appointed her successor and acceded to the throne as Emperor Kōnin. Princess Inoe and her son, Prince Osabe, were nominated as the Empress and the crown prince respectively, because of her noble birth.
The sons of Niigasa had not been considered to be successors until 772, when the Empress (Inoe) was suddenly stripped of her rank following accusations that she had cursed the Emperor. The crown prince, her son, was also disinherited. They were dead two years later. Subsequently, Niigasa's son Prince Yamabe was appointed as the crown prince and acceded to the throne as Emperor Kanmu.
Legacy
In 2001, Emperor Akihito told reporters:
I, on my part, feel a certain kinship with Korea, given the fact that it is recorded in the Chronicles of Japan that the mother of Emperor Kammu [Niigasa] was one of the descendant of King Muryong of Baekje.
It was the first time that a Japanese emperor publicly referred to Korean blood in the imperial line.
In the same year, the Imperial Household Agency released an official statement that included Emperor Akihito's message in which he mentions Takano no Niigasa.
