Successfully defended the following year by the Imperial forces led by Kusunoki Masashige,[2] it would eventually fall to the Ashikaga shogunate in 1390.

Kusunoki's success here made up for his loss two years earlier at the siege of Akasaka, where surrender was forced by the denial of water supplies.

Unlike at Akasaka, however, Kusunoki made sure that Chihaya could stand effectively against many attacks, which included the Hōjō's use of movable bridges and fire.

[3][4][5][6] The fortress' position near the summit of the mountain further aided in its defense, allowing Kusunoki's inferior numbers to not be a hindrance in such limited space.

His forces employed their superior knowledge of the ridges and ravines of the area to great effect, ending in a successful defense and the enemy's retreat once they learned of the collapse of the Hojo Rokuhara troops in Kyoto.
