This page compiles notable figures under the Toraijin classification of lesser importance and lack of information. Many of them have conflicting background stories with Korea being the place of origin in their respective original texts, but being given royal heritage from Chinese emperors later in the Shinsen Shōjiroku. According to historian (栗田 寛), it was common for Korean descendants to rely on prominent families for their lineage in order to raise their social status.
Generally, like with most notable Toraijin figures, they are considered fictional regardless of their supposed place of origin or self-proclaimed lineage.
Hachita no Kusushi
was an individual from Paekche, who is later said to be a descendant of Sun Quan according to the Shinsen Shōjiroku (815).Shoku Nihon Kōki (続日本後紀) But due to conflicting information from different sources, and the natures of said books, Hachita no Kusushi may be a fictional individual that was created by his descendants. Such sentiment is posited by historians such as Hirose Yoichi (廣瀬 陽一) who states that descendants that claimed heritage from Hachita no Kusushi is not genealogically accountable.
Irigumo of Kaya
was a king from the Kaya confederacy and the founder of the Tatara clan according to the Shinsen Shōjiroku (815).Shinsen Shōjiroku (新撰姓氏録): 諸蕃 According to the book, it is said that the king hailed from Kaya, however, due to Kaya being a confederacy, it is difficult to identify which kingdom Irigumo is from.His name only appears in the Shinsen Shōjiroku and in no other sources. The name is not found in Korea or Japan, outside the book.
In addition, because the book is also criticized by modern historians for being unreliable to be viewed as a primary source, it is entirely possible that a king named "Irigumo" is fictional.
Mantoku no Omi
was an individual from Goguryeo (spelled "Koma/高麗") according to the Shoku Nihongi (797)Shoku Nihongi (続日本紀) and the founder of the Ōtomo clan. It was later added in the Shinsen Shōjiroku (815) that he was a descendant of Emperor Gaozu of Han, however, much like the other claims found in the books, these claims are scrutinized.
Shamonei
was an individual from Paekche according to the Shoku Nihongi (797) and the grandfather to (高丘宿禰比良麻呂/高丘比良麻呂). His origin is changed in the Shinsen Shōjiroku (815) to have come from China, however, this may be an aggrandization by his descendants.
There is a theory positing that Shamonei was a member of the Sa clan or the Sataek clan (沙宅氏/사택씨), famous for (沙宅紹明), of Paekche.
Tarisusu
was an individual from Paekche according to the Shinsen Shōjiroku (815).
His name is written twice under different characters each classified under different categories. His first and original name, "多利須須" contains a footnote that he was from Paekche. However, an alternate spelling under "太利須須" with only a single character difference is classified under "Kan (漢)" which meant mainland China. It is said that he has roots in the Wu state.
There is a possibility that the two names are from different individuals, but the likelihood is low and is most likely the result of his descendants claiming different origins of their founder by putting a minor distinction in his name.
