Kose clan

The name is also used for Kose and Ise. An ancient clan based in Kose-go, Takechi-gun, Yamato Province (the area from Takatori-cho, Takaichi-gun, Nara Prefecture to Gose City). In the Kojiki (Records of Ancient Matters) (Kogenki), it is written that Takeuchi no Sukune's son, Kose no Okara no Sukune, was the ancestor of the Kose no Omi, Sasakibe no Omi, and Karube no Omi. In the Nihon Shoki, the clan of Kose appears intensively after the Minister of the Emperor Keitai's reign, Kose no Ohito, and is thought to have been a new clan that rose to prominence in the 6th century. The fact that the man was appointed as a minister is questionable, given that his daughters, Satehime and Kakarihime, became the wives of Emperor Ankan, but when we examine the activities of the clan members after the reign of Emperor Kinmei, it appears that they were involved in Korean affairs and had great influence as a military clan. Under the Soga clan government, they held the important position of Maetsukimi, who assisted the minister, and in 649 (Taika 5), ​​Tokuda was appointed as the left minister. During the Jinshin War (672), the clan sided with the Omi court, but in 684 (the 13th year of Emperor Tenmu's reign) they were given the surname Ason, and until the early Heian period, the clan produced many nobles, including Kuromaro, Maro, Ouji, Sakaimaro, Natemaro, and Notari.

許勢、居勢にもつくる。大和(やまと)国高市(たけち)郡巨勢郷（奈良県高市(たかいち)郡高取(たかとり)町から御所(ごせ)市にかけての地）を本拠とした古代豪族。『古事記』（孝元(こうげん)記）に建内宿禰(たけしうちのすくね)の子許勢小柄宿禰(こせのおからのすくね)は許勢臣(おみ)、雀部(ささきべ)臣、軽部(かるべ)臣の祖とある。巨勢氏の氏人は『日本書紀』では継体(けいたい)朝の大臣(おおおみ)巨勢男人(おひと)以降に集中的に現れ、6世紀に入って台頭した新興氏族と想像される。男人の大臣就任は、その女(むすめ)の紗手媛(さてひめ)、香香有媛(かかりひめ)が安閑(あんかん)天皇妃(ひ)とされたこととあわせて疑いがもたれるが、欽明(きんめい)朝以降の氏人の活動を点検すると、朝鮮問題に関与し、軍事氏族として大きな勢力を有したらしい。蘇我(そが)氏政権下では大臣を補佐する大夫(まえつきみ)の要職にあり、649年（大化5）には徳陀(とこだ)が左大臣に任ぜられた。壬申(じんしん)の乱（672）では近江(おうみ)朝側に属したが、684年（天武天皇13）朝臣(あそん)の賜姓にあずかり、その後も平安朝初期まで一族から黒麻呂(くろまろ)、麻呂(まろ)、邑治(おうじ)、堺(さかい)麻呂、奈氐(なて)麻呂、野足(のたり)ら公卿(くぎょう)を輩出した。
