History

Iwasakiyama Fort was the northernmost fortification in the chain of field castles extending southward toward Shizugatake Fort. It marked the outer edge of Hideyoshi’s second defensive line, overlooking the northern tip of Lake Yogo and guarding the approach into Yogo Valley.

The fort was held by Takayama Ukon, the Christian daimyō known for his tactical acumen and loyalty to Hideyoshi. During the Battle of Shizugatake in 1583, Iwasakiyama came under attack alongside nearby Oiwayama Fort. However, Takayama reportedly offered little resistance, abandoning the position and retreating back to Tagamiyama Castle.

Contemporary accounts suggest this decision may have been influenced by the fact that the fort’s construction was not yet complete and lacked sufficient defenses to withstand a serious assault.
