Suitengu Shrine and Its Deities — Emperor Antoku and the Gods of Water
Suitengu Shrine is dedicated to four deities: Amenominakanushi-no-Kami (the primordial deity of the universe), Mizuhanome-no-Kami (goddess of water), Emperor Antoku (the child emperor who drowned at the Battle of Dan-no-ura), and Kenreimonin (his mother). The head shrine is Suitengu in Kurume, Fukuoka, but the most famous is Suitengu Shrine in Nihonbashi, Tokyo.
The shrine is celebrated nationwide for blessings of safe childbirth, matchmaking, protection from water, and good fortune — particularly the tradition of visiting on the Day of the Dog (Inu-no-hi) for safe pregnancy prayers.
The Tragedy of Emperor Antoku
Emperor Antoku was born as the grandson of Taira no Kiyomori and ascended the throne at age 2. In 1185, at the Battle of Dan-no-ura, as the Minamoto forces closed in, his grandmother held him and whispered “There is a capital beneath the waves too” before plunging into the sea. He was only 8 years old.

The Day of the Dog (Inu-no-hi)
The tradition of praying for safe childbirth on the Day of the Dog comes from the dog’s reputation for having many healthy puppies. This day occurs 2-3 times a month, and pregnant women and their families line up — sometimes from before dawn — at Suitengu Shrine in Nihonbashi to receive the sacred iwata-obi (maternity sash).

FAQ
When is the Day of the Dog (Inu-no-hi)?
The Day of the Dog occurs every 12 days according to the traditional twelve-zodiac calendar, making it appear 2-3 times each month. The most common timing for safe childbirth prayers is the Dog Day during the fifth month of pregnancy (entering the stable period). Check the shrine’s official website or search for a Dog Day calendar for the current year.
What is an iwata-obi and how is it used?
An iwata-obi is a sacred maternity sash worn during pregnancy to protect the abdomen from cold and external pressure. It is received at Suitengu after a blessing ceremony, typically on a Dog Day in the fifth month. After giving birth, it is customary to return to the shrine with a thanksgiving visit and return or present the sash.
