Hideyoshi's half-brother Hashiba Hidenaga led 90,000 men, landing near Takajō (Taka Castle). Within the previous several years, the Shimazu clan of Satsuma province had spread across the island, seizing the Ōtomo clan capital of Funai. In doing so, they had become a significant power in the region, and threatened Hideyoshi's supremacy over Japan. Fighting their way through the Toyotomi forces, the Shimazu effected a retreat, leaving Takajō and the surrounding area to Hidenaga.
