Location: Taka Castle in the Niiroin area of the Koyu District of Hyūga Province
Synopsis: As one facet of the Conquest of Kyūshū, Toyotomi Hidenaga invaded Hyūga from the north, laying siege to Niiroin-Taka Castle defended by a retainer of the Shimazu clan. The garrison of 1,300 soldiers withstood a hail of flaming arrows and arquebus fire from the Toyotomi forces, but a loss by the main division of the Shimazu army at the Battle of Nejirozaka forced them to turn-over the castle.
