History
Oiwayama Fort was the middle of three key mountaintop positions in Hideyoshi’s second defensive line extending up to Shizugatake Fort. Nakagawa Kiyohide, one of Hideyoshi's most trusted retainers was commanded to build the fort on March 17, 1873. On the morning of April 20, Shibata Katsuie’s general Sakuma Morimasa launched a bold attack while Hideyoshi was tied up in Gifu. Sakuma bypassed the well-defended Shizugatake summit and struck directly at Oiwayama via the lakeside route. In a brutal and chaotic fight, Nakagawa was killed in action at the castle, making Oiwayama Fort the first and only major position on Hideyoshi’s line to fall during the battle.
The loss of Kiyohide was a heavy blow, but it also triggered Hideyoshi’s famed counteroffensive. On his return from Ogaki, Hideyoshi quickly assessed the situation, gathered his troops at Tagamiyama Castle, and launched a rapid pursuit that routed Sakuma’s forces and turned the tide of the campaign.
Field Notes
The castle site itself is quite small and requires only about 20 minutes to view it in its entirety. To reach the castle you need to either hike 2km downhill from Shizugatake Fort or 1.1 km up from Iwasakiyama Fort. The main enclosure is well maintained and signposted but the side baileys are overgrown and hard to get into.
