Ogawa Dojo is a dojo in Izuhara. In the events of Ghost of Tsushima, is a major Mongol territory and thus must first be liberated, hence its name initially being Liberate Ogawa Dojo. It is located near Yoichi's Slope on the southern border of Hiyoshi bordering Ariake.
Ogawa Dojo is a dojo that was taken over by the Mongols by means of a trebuchet on the southern side, and a siege weapon on the eastern entrance. Once it was overtaken, the Mongols set up lookout towers and various yurts throughout the dojo. Additionally, they had dead peasants bodies staked outside the entrances, and cages along the western corner with deceased prisoners. They also had a black powder cache set up near the middle of the northern wall. Once Jin destroys the black powder cache, Warlord Dogar appears, and the two engage in an unnamed Duel. After Jin defeats the warlord, villagers repopulate the dojo, including a Merchant, and rid the dojo of any Mongol presence and architecture. They also replace the Mongol banners with the banners of Clan Sakai.
