Koami Jinja
小網神社
Chuo, Tokyo · Shinto shrine
A tiny Nihonbashi shrine with a reputation for strong luck built on two documented survivals — and a coin-washing well that is the reason most people come.
Koami Jinja occupies a plot barely wider than a house on a Nihonbashi side street, and it is one of the more interesting shrines in Tokyo precisely because its reputation rests on something checkable. Its association is kyoun-yakuyoke — strong luck, and the warding-off of misfortune — and the tradition points at two events. The hall was destroyed in the Great Kanto Earthquake of 1923, but the priest escaped carrying the sacred objects. In the 1945 air raids, which flattened much of central Tokyo, the shrine took no damage.
Whether you read that as protection or as chance, it is a much more concrete claim than most shrines make, and it is why the kyoun framing sticks.
Three deities are enshrined here, and unusually they come from three different registers: an Inari deity of grain and prosperity, a goddess identified with the Buddhist Benzaiten, and one of the Seven Lucky Gods. That syncretic mixture is normal in Japanese practice and worth noticing rather than tidying away.
Which kami is enshrined here
- Uka-no-Mitama-no-Kami 倉稲魂神
- An Inari deity of rice and grain, and by extension of prosperity. The shrine itself glosses him simply as O-Inari-sama.
- Ichikishimahime-no-Kami 市杵島比賣神
- A water and island goddess long identified with Benzaiten, associated with wealth and the arts. The shrine glosses her as Benzaiten directly.
- Fukurokuju 福禄寿
- One of the Seven Lucky Gods. The shrine credits him with three virtues: personal character, good fortune and wealth.
Take part
What you can actually do here
Zeni-arai — washing money. To the left as you face the main hall is a small well dedicated to Manpuku Funanori Benzaiten. The shrine's own description of the practice is one sentence: purify money in the well water, then keep it in your wallet, and you will receive fortune in money matters. It is popularly called the Zeni-arai Benten of Tokyo.
Note what the shrine does not say. There is no specified coin, no specified amount, no basket, no instruction on drying. Anything more elaborate you read elsewhere did not come from here.
The two dragons. Carved on either side of the worship-hall porch are a rising dragon and a descending dragon. The rising one carries the worshipper's prayer up; the descending one brings the response back down. You look up at them from where you stand at the offering box — most visitors never notice them.
Etiquette
Where this place differs
Two things here are not standard, and both are still in force.
- The bell rope has been removed. You cannot ring the bell. Do not look for it.
- The temizu ladles have been removed. Purify your hands under the running water directly.

Goshuin
Getting the seal here
Offered, ¥500. The shrine publishes a bilingual price sheet for everything it hands out — thirty-nine amulets, the ofuda, the goshuin and the books — linked from its own front page as Items of Blessing. Goshuincho prices vary by design.
What it does not say anywhere is whether the seal is written into your book or handed over pre-written. Collectors report that direct writing is suspended and only pre-written sheets are issued; we could not confirm that, so do not build a plan around either.
Before you go
The shrine asks visitors to stay away at certain times, and means it. It requests that people avoid 1–15 January and weekends and holidays through January and February — and, in the same breath, weekdays that fall on an auspicious date in the old calendar (taian, tenshabi, ichiryu-manbaisu, mi-no-hi), which now draw the same crowds. The queue overflows into a public street the site is too small to absorb. This is the shrine's own request, not a crowding tip.
Formal prayer services require a reservation. The official prayer page includes old month-specific booking announcements, so confirm the current application instructions and availability with the shrine before planning around a slot. Those old announcements do not establish a standing booking-release schedule. Socks or stockings are required for the service.
There is no parking, no bicycle parking, and no mail order of amulets.
