One of Japan's Top Power Spots
A Guide to Ikonahime-jinja Shrine (Shirahama Shrine)

Ikonahime-jinja Shrine (Shirahama Shrine) sits on Shirahama Beach in Shimoda City, Shizuoka Prefecture, and is Izu's oldest shrine, with a history of more than 2,400 years since its founding.

Its official name is Ikonahime-jinja Shrine, but it is affectionately known by locals and visitors alike by its common name, Shirahama Shrine.

Having watched over the Izu region throughout its long history, the shrine is home to numerous cultural properties, including the "Byakushin Grove," designated a national natural monument.

Step into the solemn grounds surrounded by deep greenery, and you can feel the quiet, sacred air, as if 2,400 years of prayers have soaked into the very ground.

Ikonahime-jinja Shrine (Shirahama Shrine) enshrines five deities: Ikonahime-no-Mikoto, Mishima-Daimyojin, Mime, Wakamiya, and Tsurugi-no-Miko.

The principal deity, Ikonahime-no-Mikoto, is the consort of Mishima-Daimyojin.
She is deeply revered as a deity of matchmaking, conception, and child-rearing.

Mishima-Daimyojin is known as a deity who brings prosperity, and because the shrine enshrines this husband-and-wife pair of deities, it is also said to bless visitors with marital harmony.

It is a power spot visited not only by couples and married partners, but also by many who wish for good new relationships.

Amulets and goshuin (shrine seals) for good relationships are also available at the shrine, making them wonderful gifts for someone special.

One of the most striking presences on the grounds is the sacred tree "Yakushi no Byakushin" (Japanese juniper).

Estimated to be around 2,000 years old, it is a mysterious giant tree that is still alive today.

Another Japanese juniper on the grounds, called the "Byakushin of the White Dragon," is said to have lived for 1,000 years and remained standing for another 1,300 years after its death.

This grove of sacred junipers is designated a national natural monument, a precious piece of natural heritage that tells the story of the shrine's long history.
Standing before these sacred trees, you can feel on your skin the extraordinary presence they have taken on over so many years.

The sheer presence of this 2,000-year-old giant is more powerful than any photograph can convey.

The combination of the blue sea, white sand, and vermilion torii gate creates a view found nowhere else.

Yes, the area around the shrine is at its most crowded of the year during this time.

Since Shirahama Beach right in front of the shrine is a popular summer beach, National Route 135 in front of the shrine gets congested during the summer holidays, especially on weekends and around the Obon holiday.

If you're planning to visit, we recommend coming early in the morning or on a weekday.

Outside of summer (fall through spring), crowds ease up considerably, letting you enjoy the grounds at a relaxed pace.

Yes, you can walk there.

After paying your respects at the main hall, you can follow the path behind the grounds out to Shirahama Beach.

From there, the red torii gate stands on the rocky outcrop (Daimyojin Rock) to your left.

Since you'll need to walk a short way across sand and rocks, we recommend wearing comfortable walking shoes.

Please also note that depending on the weather and wave conditions, it may not always be possible to get close to the torii gate.

Yes, you can receive one at the shrine office.

In addition to the regular goshuin, limited-edition designs such as papercut goshuin are sometimes available.

Reception hours run roughly from 9:00A.M. to 4:00P.M. (with some seasonal variation).

Whether you receive a hand-written goshuin or a pre-written paper version can vary by day, so please check on-site for details.

Early morning (before noon) is highly recommended.

Since the shrine gets especially crowded during the summer swimming season, visiting early in the morning is the key to enjoying the grounds at a relaxed pace.

Visiting while the morning light streams in also heightens the sacred atmosphere.

During the quieter hours in particular, you can take your time admiring the sacred tree, the torii gate, and the natural surroundings, and settle your mind in the refreshing morning air.
