One of the most famous tales of construction-related human sacrifice is associated with Matsue castle (Shimane prefecture), which was originally built in the 17th century. According to local legend, the stone wall of the central tower collapsed on multiple occasions during construction. Convinced that a human pillar would stabilize the structure, the builders decided to look for a suitable person at the local Bon festival. From the crowd, they selected a beautiful young maiden who demonstrated superb Bon dancing skills. After whisking her away from the festival and sealing her in the wall, the builders were able to complete the castle without incident.
However, the maiden’s restless spirit came to haunt the castle after it was completed. According to folklorist Lafcadio Hearn, who described the castle’s curse in his 1894 work “Glimpses of Unfamiliar Japan,” the entire structure would shake anytime a girl danced in the streets of Matsue, so a law had to be passed to prohibit public dancing.
