Hosokawa Sumimoto

Hosokawa Sumimoto (細川 澄元, 1489 – June 24, 1520) was a samurai commander in the Muromachi period during the 16th century of Japan.

Masamoto did not have his own child and originally had decided to let Hosokawa Sumiyuki, who was from Kujyō clan, succeed the house.

[2] Sumimoto was attacked by a retainer of Sumiyuki, Kozai Motonaga, and escaped to Koga, Ōmi Province, taking refuge at Rokkaku Takayori.

In 1493, Masamoto had deposed the 10th Shōgun Ashikaga Yoshiki (Yoshitane), who later escaped from confinement and fled to eastern countries, looking for a chance to regain his position.

Ōuchi Yoshioki left the capital in 1518 to maintain his own dominion, and regarding this as a chance, Sumimoto attempted another movement on Kyoto in the next year, cooperating with Miyoshi Yukinaga.
