Koami Shrine, Nihonbashi: Wealth Spot

In a corner of Nihonbashi surrounded by towering office buildings sits the compact Koami Shrine. With a history of more than five hundred years, it is one of the most visited power spots in Tokyo, famous for warding off misfortune and inviting wealth. A wartime legend tells that every soldier who prayed here before deployment returned home safely, earning it a reputation as the shrine of strong fortune and protection.

Highlights

• Coin-Washing Well (Tokyo Zeniarai Benten): Money rinsed in the sacred well and kept in your wallet is said to grow your financial luck.
• Rising and Descending Dragon Carvings: The exquisite dragon carvings on the main hall are a designated cultural property of Chuo Ward and a symbol of good fortune.
• Fukurokuju and Benzaiten: Counted among the Seven Lucky Gods of Nihonbashi, the shrine combines blessings for long life and wealth.
• Concentrated Atmosphere of a Small Precinct: Within its limited grounds, prayers feel densely gathered, creating a uniquely sacred air.

Enjoying the Seasons

At the Doburoku Festival, held each year around November 28 (with the date shifting in some years when it falls on a Sunday), doburoku sake brewed from the new harvest is served, and the grounds fill with visitors giving thanks for the harvest and hoping for good fortune. Said to date back to the late Edo period, the festival also offers a special goshuin seal available only on that day. The New Year draws long lines of people seeking luck, so if you prefer a calm visit, weekday mornings are best. Its location makes it easy to drop by year-round while strolling the Nihonbashi area.

Access and Basic Information

• Location: 16-23 Nihonbashi-Koamicho, Chuo-ku, Tokyo
• Access: About 5 minutes on foot from Ningyocho Station (Tokyo Metro Hibiya Line), or about 8 minutes from Suitengumae Station (Hanzomon Line)
• Hours: Grounds open all day
• Shrine office (amulet office): Roughly 9:00 to 17:00 (varies on festival days)

Practical Travel Notes

• Getting there: The shrine sits midway between Ningyocho and Suitengumae Stations, within walking distance of both. The surrounding Nihonbashi and Ningyocho old-town district pairs easily with a stroll.
• Crowds: The first three days of the New Year and the November Doburoku Festival are especially busy, and because the grounds are small the lines stretch long. Weekday mornings are best for a calm visit.
• Coin-washing custom: Rinse coins placed in a basket with the Benten spring water, let them dry, and carry them in your wallet as seed money. The custom is to keep rather than spend them.
• What to combine: As one shrine on the Nihonbashi Seven Lucky Gods route, it honors both Fukurokuju and Benzaiten. Paired with nearby Suitengu it makes a half-day walk.
• Etiquette: The grounds are small and crowd easily, so be considerate with photography and lingering out of respect for other worshippers.

A Quick Tip

The grounds are small and can get crowded, so be considerate of other worshippers. The custom is to keep your washed coins as seed money in your wallet rather than spending them. Use the shrine as the starting point for the Nihonbashi Seven Lucky Gods route for a blessing-filled half-day walk.
