About this place
Suitengu stands above street level in Nihonbashi, rebuilt in 2016 on a raised podium with the shrine office beneath. It is the shrine Tokyo associates with pregnancy: people come on the day of the dog, which falls every twelve days, and its safe-birth charm is not a pouch but a bolt of bleached cotton meant to be wrapped. The shrine explains where that came from, and the explanation is a good deal more specific than most.
Origin and history
Suitengu began in Kyushu, at Kurume in what is now Fukuoka. The Tokyo shrine dates from 1818, when Arima Yorinori, the ninth lord of Kurume, branched the Suitengu his family worshipped to their residence at Mita Akabane.
The Arima connection to the deity runs further back. The family descends from the Akamatsu, and after the Kakitsu disturbance of 1441 they fled to the village of Arima, in what is now northern Kobe, and took their name from the place. They were later brought back to prominence under Hideyoshi, and to keep the deity of the Arima shrine in mind they adopted that shrine's three-comma crest as their own. The shrine records that only the head of the house is permitted to wear it. In 1620 Arima Toyouji received the Kurume domain and built the Suitengu hall there.
Four figures are enshrined. Amenominakanushi appeared, in the account the shrine gives, at the very beginning of the universe, at the highest point of heaven, and is the ancestor of the Japanese deities. The other three belong to the end of the Taira. Emperor Antoku was born to Emperor Takakura and Kenreimon'in and became emperor at three; in 1185, aged eight, he was carried into the sea at Dan-no-ura by his grandmother, Nii-no-Ama, the widow of Taira no Kiyomori. Kenreimon'in survived the battle and spent the rest of her life praying for her clan.
What it is locally associated with
The charm that is a belly band
The safe-birth charm here is a length of bleached cotton, the misuzu-obi. It is blessed on the day of the dog and given out daily, so any visit gets a dog-day charm.
documented historyA bell cord, and an easy birth
The shrine records that a pregnant woman was given a cast-off of its bell cord, wore it as a belly band, and had an unusually easy delivery. The story spread, and the cotton became the charm.
folk traditionThe day of the dog
Dogs bear many young and bear them easily, so the twelve-day cycle brings a dog day two or three times a month, and that is when people come.
documented historyThe child-treasure dog
A dog statue in the grounds. Stroking it is said to bring the blessing of children, which is the practice here rather than a published rule.
local custom
What this shrine is petitioned for is unusually concentrated, and it comes from the first of its four deities. Amenominakanushi is the ancestor of the Japanese deities, and the shrine says his virtue extends without limit to safe childbirth and to the granting of children. Both have their own page on the shrine's site, and both are why this page carries the fertility tag; warding off misfortune has a page too, which is where protection comes from.
The safe-birth charm is the thing most worth knowing about, because it is not a charm in the usual sense. It is a length of bleached cotton, meant to be wrapped as a belly band, and the shrine tells you exactly why. Long ago a pregnant woman was given a cast-off of the shrine's bell cord, the bleached rope you pull to sound the bell, and wore it at her belt-blessing praying for a safe delivery. Her birth was exceptionally easy. The account passed from person to person until the shrine began giving out the bleached cord itself as a safe-birth charm. It is now called the misuzu-obi, and it is blessed on the day of the dog and handed out every day, so a visit on any date still gets a charm prayed over on a dog day.
The day of the dog is the other half of it. Dogs bear many young and bear them lightly, and the shrine says people come on the dog day to take after them. It comes round once every twelve days, so two or three times a month, and the shrine is practical about the consequence: those days are crowded, and it suggests taking the blessing on a quieter day and wrapping the band at home on the dog day instead. Prayers are not by reservation at all, and it also blesses charms sent by post for those who cannot travel.
In the grounds there is a dog statue, the child-treasure dog, which visitors stroke for the blessing of children, and a sub-shrine to Hōshō Benzaiten.

Visiting tips
The general form is in the visiting guide below. Specific to Suitengu:
No prayer here is booked in advance. You come on the day you want, which is why the dog days are so busy; up to six people may go up into the hall, and only two on a dog day.
The safe-birth charm is meant to be worn rather than carried. It is the belly band itself, traditionally wrapped at the belt-blessing in the fifth month of pregnancy.
The shrine performs blessings for people who cannot come, by post, and states that this is for those unable to travel rather than a convenience.
The site sits on a raised podium above the street with the office underneath, which is worth knowing if you are visiting late in a pregnancy: the approach is by steps or lift rather than a level walk.
