Hosokawa Tadaoki
Jinju castle was an important castle that guarded Jeolla province. Ukita Hideie and Hosokawa Tadaoki agreed on taking Jinju castle because if the Japanese captured it, it would open up a new road to Jeolla, and they would be able to attack Gwak Jaeu's guerilla forces hiding in the area. Jeolla was also a place for plenty of loot. Ukita also agreed to recapture Changwon, a small fortress that led to Jinju castle. Therefore, an army of 30,000 men to recapture Changwon and Jinju set out. The Japanese Seventh Contingent arrived at Jinju on 8 November with 30,000 men under Kato Mitsuyasu, Hasegawa Hidekazu, Nagaoka Tadaoki, and Kimura Shigeji.
