Said to be a female great serpent dwelling in the pond of Chokeiji in Izumi Province. Leading many snakes, she was styled the “Serpent King,” quietly watching over people near the temple grounds. Around the Bunsei era, she fell for the beauty of the abbot, Zen monk Shoyama, and slipped into the temple disguised as a lost woman. Sensing something amiss, the abbot struck her with a blade. As she lay dying, the serpent vowed to protect Chokeiji. Thereafter the pond became a place of memorial offerings and reverence, tied to taboos against harming snakes and to prayers for rain and abundant harvests. The origin of her title and its rank remain unclear, likely influenced by regional worship of serpent kings (Ja-o, Ja-o Gongen). Though the pond was later filled in and no visible remains survive, her image endures in local oral tradition and temple lore.
