TRANSLATION: human pillar
HABITAT: found in bridges, castles, dams, and other large constructions
APPEARANCE: Hitobashira refers to the gruesome practice of burying a living human being in the foundations of important buildings—bridges, dams, tunnels, and particularly castles. It was a common practice during large construction projects from ancient times through the 16th century. However there is evidence that hitobashira were still being used in some construction projects during the 20th century.
BEHAVIOR: This form of sacrifice was used as a magical ward for the building being constructed. It was believed that the sacrifice of a human soul would appease the nature spirits in an area—particularly the river spirits in areas where flooding was common. They were also used to ward castles against assault, fire, and other disasters both man-made and natural.
ORIGIN: Although hitobashira literally means human pillar, the actual meaning is more complicated. Pillars and Shinto have a long relationship—kami can be enshrined in pillar-like sacred trees, the oldest shrines were built upon pillars, and hashira, in addition to meaning pillar, is also used as the josūshi—Japanese counter word—for kami. The bashira in hitobashira refers not to a literal pillar, but actually to this counter word. The human was enshrined in a manner similar to a kami of the building to which he or she was sacrificed, becoming both a literal pillar and a connection to the gods. Very often, small stone memorials were erected in honor of the hitobashira who were sacrificed to a building. Some still stand today.
LEGENDS: A few famous castles in Japan are connected to legends of hitobashira. Maruoka Castle in Fukui Prefecture (old Echizen Province), one of the oldest surviving castles in Japan, is said to contain a hitobashira in the central pillar of the keep.
While Maruoka Castle was being constructed, its walls kept collapsing no matter how many times they were repaired. It was decided that a person should be sacrificed and made into a hitobashira in order to improve the stability of the castle. A poor, one-eyed woman named Oshizu was selected for the honor of becoming a hitobashira. As a reward for her sacrifice, she was promised that her son would be made a samurai. After she was sacrificed the castle was completed. However, before her son could be made a samurai, the castle’s lord was transferred to another province, and the promise was left unkept.
Every year thereafter, the castle’s moat overflowed when the heavy spring rains came. The people of Maruoka blamed this on Oshizu’s vengeance, and called this rain “tears of Oshizu’s sorrow.” Afterwards, a cenotaph was erected for Oshizu inside the castle grounds to calm her spirit.
