Ogasawara Clan - Ogasawara-Miyoshi Line

Ogasawara-Miyoshi Line

The Miyoshi clan of daimyō were cadet descendants of the Ogasawara; and through them, they were also descendants of the Seiwa-Genji Minamoto. At the beginning of the 14th century, Ogasawara Nagafusa established himself in Shikoku. Amongst his descendants in the 8th generation was Yoshinaga, who established himself at Miyoshi in Awa province (now Tokushima Prefecture).

Osagawa Yoshinaga took the name Miyoshi Yoshinaga and became a vassel 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 Emperor Chōkei; however, his family in Shikoku disappears from history during this troubled period. 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.
