In the year Tenshō 5 (1577), Yoshisuke's vassals, in particular Fukunaga Suketomo and Mera Norishige, betrayed Suketaka.

"[citation needed] Sōrin invaded Hyūga Province and fought against the Shimazu clan, but his army was defeated in the Battle of Mimigawa at the Mimi river.

Sōrin moved to Iyo Province and asked the Kōno clan for help with their 20 retainers, without Yoshikatsu and Yoshikata.

However, they fell into poverty and Kawazaki Sukenaaga, one of his vassals, ran a sake brewery to earn money.

At that time, Sanpō, a member of the Yamabushi, was asked by Kawazaki Sukenaga[clarification needed] to pray for the revival of the Itō clan.

In the year Tenshō 10 (1582), at the Battle of Yamazaki, Suketaka played an active part and was bestowed the Kurikara spear and 500 Koku territory in the Kawachi Province as a reward.
