Ogasawara clan
Osagawa Yoshinaga took the name Miyoshi Yoshinaga and became a vassal of the Hosokawa clan, who were then the strongest force on the island. Accounts from the late 16th century include mention of Miyoshi Yoshitsugu as the nephew and adopted son of Miyoshi Chōkei. Any remnants of the Miyoshi branch of the Ogasawara clan would have been vanquished by the Chōsokabe clan as they gradually took control of the entire island of Shikoku.
