Matsura Sayohime (松浦佐用姫) was a legendary heroine in Japanese Buddhist mythology. As recounted, she was born to Lord Kyōgoku after he and his wife prayed to the Bodhisattva Kannon. After her father's death, Sayohime was too poor to sponsor a memorial service for him; to raise funds, she sold herself to a man named Gonga no Tayu, who (unbeknownst to Sayohime) intended to sacrifice her to the snake deity of his village in place of his own daughter. When presented to the snake, Sayohime read from the Lotus sutra, enabling the deity to achieve enlightenment and shed its monstrous form. The deity then returned Sayohime to the care of her mother.
