The Mimizuka is a monument in Kyoto, Japan, dedicated to the Seven-Year War fought against Korea from 1592 to 1598. The name translates to Ear Mound, and the monument enshrines the ears and noses of approximately 38,000 Koreans killed during Toyotomi Hideyoshi's invasions. Traditionally, Japanese warriors would bring back the heads of enemies slain on the battlefield as proof of their deeds. However, because of the number of civilians killed along with soldiers, and crowded conditions on the ships that transported troops, it was far easier to just bring back ears and noses instead of whole heads.
