In theBook of Liang, the article on "Yamato" (梁書倭伝) states that his son Je stood up after the death of "Ya", and his son Xing stood up after his death.[2]。
In the article in the Sung Shu, Je takes the surname "Wa" (倭) as did the previous Japanese king Jin, but does not clarify his relationship to Jin. Since they do not name the continuation, there is a theory that Je and Chin were not close blood relatives, and since theNihon Shoki shows a struggle in the succession to the throne afterEmperor Nintoku, the possibility of the existence of such a struggle over the throne is pointed out[4] In addition, since theWazui [ja] can be seen as a particularly powerful royal family in the Chin period, there is a theory that there were two royal forces at that time (Mozu Kofun Cluster andFuruichi Kofun Cluster), and that Je may have been a lineage of this Wazui[4]。
