Takano no Niigasa
(高野 新笠, ca. 720 – 790)
Niigasa was daughter of Yamato no Ototsugu. 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 of the line of King Muryong of Baekje." It was the first time that a Japanese emperor publicly acknowledged Korean blood in the imperial line. According to the Shoku Nihongi, Niigasa is a descendant of Prince Junda, son of Muryeong, who died in Japan in 513 (Nihon Shoki Chapter 17).
Ōuchi clan
descendants of Prince Imseong
In 611 Imseong left Baekje for Japan known at the time as "Yamatai". The Japanese called him Rinshō Taishi because of the Japanese reading of the characters in his name. Prince Shōtoku (聖德太子 Shōtoku Taishi, 574-622), regent for Empress Suiko gave Imseong the name Tatara (多々良) and designated him ruler of Ōuchi Agata (大内縣) in the fiefdom of Suō-kuni (周防国), in the area that is today the eastern part of Yamaguchi Prefecture.
