A series of battles around Numazu in Suruga Province ensue.

Masayuki refuses and defeats a Tokugawa army sent to chastise him near Ueda after recieving the assistance of Uesugi Kagekatsu. The Hôjô attempts to take Numata, held by Sanada Masayuki's uncle, Yasawa Yoritsuna, end in failure.

Hideyoshi's host consists of some 200,000 men but no serious attempt to storm the castle is attempted. Ujinao surrenders after three months, most of which were spent debating endlessly with his advisors. He is spared to go into exile at Mt. Koya along with certain of retainers and relatives.
