Osakabe hime is a reclusive yōkai who lives high up in the keep of Himeji Castle. She takes the appearance of a majestic old woman wearing a 12-layered kimono.
Osakabe hime is a powerful yōkai, capable of manipulating people like puppets. She is extremely knowledgeable about many things and controls a multitude of kenzokushin—animal-like spirits who act as messengers. She can read a person’s heart and see their true desires. She can then manipulate them any way she pleases. It is rumored that anybody who sees her face will die instantly.
Osakabe hime absolutely hates meeting people. She spends most of her time hidden away in secret areas of Himeji Castle. However, once a year, she comes out of hiding to meet with the castle lord and foretell the castle’s fortune for the next year.
Osakabe hime’s true identity is a mystery. By popular account, she is actually an elderly nine-tailed kitsune who takes the form of this yōkai. According to other accounts, she may be a snake spirit, or the ghost of one of Emperor Fushimi’s favorite courtesans. She may even be the sister of Kame hime, a similar yōkai who lived in Inawashiro Castle in Mutsu Province.
Another common legend is that she was originally the kami of the mountain upon which Himeji Castle was built. When Himeji Castle was expanded by Hideyoshi in the 1580s, the shrine dedicated to the local goddess of Mount Hime, Osakabegami, was removed. The goddess was re-enshrined in Harima Sōja, a shrine dedicated to several gods. In the 1600s, when the lord of the castle, Ikeda Terumasa, fell mysteriously ill, rumors arose that his sickness was due to the goddess’s anger at having been removed. In order to appease her, a small temple was built in the keep and Osakabegami was re-enshrined at the top of her mountain. Osakabegami may be the true identity of Osakabe hime.
During the Edo period, a young page named Morita Zusho went on a dare to go see if a yōkai really lived in the upper floors of Himeji Castle. He waited until nightfall, and then—paper lantern in hand—he climbed to the top of the keep. As brave as he was, Zusho couldn’t help imagining what would happen to him if there really was such a creature up there. Finally, when he reached the top floor, he saw a faint light coming from a door in the attic. He peeked in, but whoever was inside had heard him. A woman’s voice called out, “Who’s there!?”
Zusho was paralyzed with fear. He heard the sound of a kimono rustling. The door opened up to reveal a beautiful, elegant woman in her thirties wearing a splendid 12-layered kimono. Zusho felt his strength return and politely introduced himself and explained his reason for coming.
Amused, the yōkai replied, “A test of bravery, you say? You will need some proof that you actually saw me.” She gave him a neck guard of a helmet— piece of his master’s own family heirloom armor—to show his master as proof that he met Osakabe hime.
The next day, Zusho told the story of what had happened to his master. Everyone had trouble believing him because they had always heard that the yōkai took the form of an old woman and not a young one. But when Zusho presented the neck guard, his master was shocked and had no choice but to believe the story.
