Kubizuka

Kubizuka (首塚, literally neck mound in Japanese, often translated as head tomb) is a type of burial mound in Japan, in which severed heads are interred.

The heads were often those taken as trophies following a battle or in some cases, the kubizuka holds the heads of those who were executed by decapitation, whether prisoners of war or convicted criminals who were sentenced to death.

In Japanese history, battles were often followed by a head-viewing ceremony, in which warriors presented the head(s) of opponents they had killed in combat to their commander.

There are kubizuka enshrining a single person (like an enemy samurai commander), so they do not become a vengeful onryō later, and kubizuka enshrining many soldiers (zohyo) killed in one battle, such as the grave associated with the Battle of Sekigahara.

Mimizuka (耳塚, ear mound, an alteration of the original hanazuka 鼻塚, nose mound[1][2][3] ) is a tomb where the noses of the killed Korean and Chinese soldiers and civilians[4] in the Japanese invasions of Korea (1592–1598) were gathered and buried as the substitute of heads, because it was impossible to bring back the severed heads from overseas; it has the same symbolic meaning as kubizuka.
