Suiten-gū (水天宮) is the name of numerous Shinto shrines in Japan. Suiten-gū shrines are famous for their blessings of safe childbirth, but are also known to provide protection from water-related natural disasters, protection from fire, and aid in childrearing. The head shrine is the Suiten-gū in Kurume city, Fukuoka, which also enshrines members of the Taira clan. The Tokyo Suiten-gū is also known as a patron of Mizu shōbai workers.
