Tōyama
The Toyama of Mino traced their origin to Kato Kagekado, a retainer of Minamoto no Yoritomo rewarded with Toyama manor in Ena district around the 1190s. His eldest son Kagetomo took its name and first appeared in records in 1221, when he executed the court noble Ichijo no Nobuyoshi at Iwamura after the Jokyu War.
From Iwamura Castle the family spread into seven houses, ranking with the Toki in eastern Mino. Some of its men served the Ashikaga shoguns directly as hokoshu, and Kagefusa fought for the Ashikaga at Minatogawa in 1336.
The Toyama submitted to Takeda Shingen in 1554–1556, and Oda Nobunaga married his adopted daughter Lady Otsuya to Kagetō of Iwamura. The main houses of Iwamura, Iibama, Yasuki and Akeshō were destroyed in the Oda-Takeda struggle. The Akechi, Kushiwara and Naegi branches joined Tokugawa Ieyasu at Sekigahara in 1600; the Naegi became daimyo and later viscounts.
