Kagawa

The Sanuki Kagawa claimed Kanmu Heishi descent and the warrior Kamakura Kagemasa as their ancestor. An earlier branch took its name from Kagawa village in Sagami. After the Nanboku-chō wars the house attached itself to the Hosokawa and entered Sanuki with the Yasutomi, having distinguished itself at Shiramine, and held the office of shugodai for generations.

The Kagawa fought in the Ōnin War and were counted among the Four Heavenly Kings of the Hosokawa. By the Sengoku age they controlled much of western Sanuki from Mitoyo. The last great head Yukikage maneuvered between the Mōri, Oda Nobunaga and Chōsokabe Motochika, taking Nobunaga's character to rename himself Nobukage and adopting Motochika's son Chikakazu as heir. In 1585 Toyotomi Hideyoshi's conquest of Shikoku cost the house its fief.
