Hideyoshi's half-brother Hashiba Hidenaga led 90,000 men, landing near Takajō (Taka Castle).
Hidenaga's forces pursued the Shimazu beyond Takajō who garrisoned by Yamada Arinobu, and began to besiege the fortress.
Three thousand Shimazu warriors dismantled the fortifications of the besiegers, and distracted them long enough to effect a cavalry attack.
However, they then found themselves flanked by 1500 Toyotomi warriors, who made every effort to give the appearance of a larger force in the Shimazus' rear, cutting off their escape.
Fighting their way through the Toyotomi forces, the Shimazu effected a retreat, leaving Takajō and the surrounding area to Hidenaga.
