Mizuko is a Japanese term that translates to "water child" and refers to the spirits of deceased fetuses or infants. In Japanese culture, it is believed that these spirits may experience suffering due to their untimely death. To honor and appease them, families often participate in rituals and ceremonies. One common practice is the creation of a Mizuko kuyo, a memorial service that includes offerings such as food, flowers, and small statues. These rituals aim to provide comfort to the spirits and help them find peace, reflecting the deep cultural significance of life and death in Japan.
