Mount Kōya
The birth of Hideyoshi's second son in 1593, Hideyori, created a potential succession problem. To avoid it, Hideyoshi exiled his nephew and heir Hidetsugu to Mount Kōya and then ordered him to commit suicide in August 1595. Hidetsugu's family members who did not follow his example were then murdered in Kyoto, including 31 women and several children.
