Wakayama Castle

Wakayama Castle (和歌山城, Wakayama-jō) in Wakayama, Wakayama Prefecture, Japan, sits at the mouth of the Kii River. Originally Ōta castle, home of the Saiga Ikki, it was captured by Toyotomi Hideyoshi in 1585, during the Siege of Negoro-ji; many monks from Negoro-ji sought refuge in Ōta, which was soon destroyed by flood. Hideyoshi ordered the building of dams on three sides of the castle, focusing the rainwaters and diverting the river to ruin the castle. As hunger set in, the samurai, monks, and peasants inside Ōta surrendered, and fifty warrior monks led a final charge against Hideyoshi's army, committing honorable suicide.
