In the Azuma Kagami, it is recorded that Katagiri Yasukage, who inherited Kagemasa's position, was granted a favor directly from Minamoto no Yoritomo, and the territories that had been confiscated by the Taira clan were returned after more than 20 years (around June 23, 1184, Juei 3).

At this time, Katagiri Genta, Tarō, and Matatarō fought valiantly against the forces of the Kyoto Protectorate, Iga Mitsukiyo, who encircled them.

Subsequently, they settled in Takatsukimura, Ika District, Ōmi Province (now Nagahama City, Shiga Prefecture), where they established their domain.

After the fall of the Asai clan, Katsumoto's son, Katagiri Sadataka, served under Toyotomi Hideyoshi as one of the "Seven Spears of Shizugatake" and gained favor, receiving 50,000 koku (a unit of measure for rice, representing wealth) in Settsu Province.

Around the first year of the Genji era, Felice Beato photographed a panorama of Edo from Atagoyama, capturing the mansion of the Katagiri family of the Koizumi Domain in the center of the image.
