山崎の戦い
After the Incident at Honnō-ji in 1582 Fujitaka refused to join Akechi Mitsuhide for the Battle of Yamazaki despite the fact that his son, Hosokawa Tadaoki, was married to Akechi's daughter, Hosokawa Gracia. Later, Fujitaka shaved his head in the Buddhist tonsure, changed his name to the priestly "Yūsai", and delegated his status as "daimyō" to Tadaoki.
