Dosojin and Koshin faith represent two of Japan’s most distinctive roadside religious traditions. Both survive as stone monuments and carvings at village boundaries and highway crossroads across Japan, bearing witness to the depth of Edo-period popular faith.

What Are Dosojin — From Road Guardians to Matchmaking Deities
Dosojin are deities protecting travel safety, boundary protection, and romantic matchmaking, enshrined at village entrances and road crossroads. In ancient Japan, they served as “road gods” guarding travelers while simultaneously acting as “boundary gods” preventing disease and evil spirits from entering communities.
How have Dosojin forms evolved over time?
Era
Form
Characteristics
Ancient
Natural stone, phallic shapes
Fertility and reproduction faith
Nara–Heian
Inscribed stone pillar (“Dosojin” character)
Influence of Taoism and Buddhism
Edo

Matchmaking and marital harmony
Modern
Diverse forms (Jizo-like, dancing figures, etc.)
Regional individuality
Sotai Dosojin (paired deities) became especially popular in Kanto and the Koshinetsu region during the Edo period, depicting a couple embracing, holding hands, or facing each other. They are venerated for matchmaking, marital harmony, and fertility.
What is the connection between Sarutahiko and Dosojin?
Sarutahiko guided the descent of the imperial grandchild in the Kojiki creation myth and is often identified with Dosojin as a deity of roads, directions, and boundaries. Sarutahiko Shrine in Ise, Mie Prefecture, is the principal shrine dedicated to this deity and is commonly visited alongside the Grand Shrine of Ise.

What Is Koshin Faith — All-Night Vigils Every 60 Days
Koshin faith developed in Japan from the Taoist “Three Corpse Worms” (sanshi) doctrine.
Why do people stay awake all night on Koshin?
According to the Taoist sanshi doctrine, three worms inhabit the human body and, on the night that falls every 60 days marked by the “Koshin” cyclical combination (kanoe-saru), they escape the body to report the person’s misdeeds to the Heavenly Emperor. To prevent the worms from leaving, communities observed an all-night vigil (Koshin-machi) until dawn.

What is carved on Koshinzuka monuments?
Of the estimated 40,000+ surviving koshinzuka across Japan, most feature Shomengongo (Blue-Faced Vajra) — a blue-faced Buddhist deity believed to destroy the Three Corpse Worms. Below the main image, the Three Monkeys (“see no evil, hear no evil, speak no evil”) are a standard motif, symbolizing the cultivation of virtue.
The Three Monkeys (mizaru, kikazaru, iwazaru) carved on the sacred stable of Nikko Tosho-gu shrine, Tochigi Prefecture. The same three-monkey motif appears on koshin-to across Japan, symbolizing the denial of the Three Corpse Worms: give them nothing to see, hear, or report. Their presence at Tokugawa Ieyasu's mausoleum illustrates how folk koshin iconography permeated Edo-period official culture.

Yasaka Koshin-do — Center of Koshin Faith in Kyoto
Yasaka Koshin-do (Kongoji Temple) (Higashiyama, Kyoto) is considered one of Japan’s Three Great Koshin sites and enshrines the Blue-Faced Vajra as its principal image. The precincts are famous for colorful kukuri-zaru — small cloth monkey dolls hung in clusters, symbolizing the binding of one’s desires. The temple is located along the popular Gion–Kiyomizudera tourist route.
A kukuri-zaru is traditionally hung after making a vow to restrain one specific desire, symbolically “binding” that impulse.
Koshin Shrines in Saitama and Edo
Saitama Koshin Shrine (Omiya) preserves the Koshin faith tradition of the Kanto region, where community members still gather on Koshin days to pray. Across Japan, Koshin shrines, halls, and stone pillars survive as physical records of the Edo-period village associations (koshin-ko) that organized these gatherings.
Sugamo Koshinzuka in Toshima, Tokyo
Toshima Sugamo Koshinzuka near the Sugamo Jizo-dori shopping street is a Koshin faith relic from the Edo period, where inscriptions like “Kyoho” and “Genroku” (Edo-era era names) record the activities of local koshin-ko associations.
A stone Jizo Bodhisattva (dated 1517) housed in a small wayside shrine in Nara City. Like dosojin and koshin-to, such anonymous roadside stone Buddhas represent the unregistered folk faith of rural Japan — absent from guidebooks yet continuously venerated by local communities for over five centuries.

How to Read Dosojin and Koshin Stone Monuments
When walking along old highways and village boundaries, you may encounter ancient stone markers. Here is how to identify them:
Type
Identifying Features
Dosojin
“Dosojin” inscription; relief of couple or paired figures
Koshinzuka
“Koshin” inscription; Blue-Faced Vajra relief; Three Monkeys
Bato Kannon
Horse-headed Kannon image; “Bato Kannon” inscription
Jizo
Small monk figure holding staff and jewel
The sides and backs of these monuments often record “[Village Name] Koshin-ko” and the date of installation — invaluable records of local Edo-period community life.
Colorful kukuri-zaru (bound monkey) fabric charms at Yasaka Koshin-do (Kongoshoin), Kyoto — one of Japan's three principal Koshin sites. Each cloth monkey is bound hand and foot, symbolizing the suppression of desire and the Three Corpse Worms. The contrast of the fierce blue Shomen Kongo deity and the vivid hanging monkeys makes this one of Kyoto's most visually distinctive off-the-beaten-path stops.

Frequently Asked Questions
Are Dosojin and Koshin the same deity?
They are distinct religious traditions often confused with one another. Dosojin are Japan-native boundary and road guardians; Koshin (Blue-Faced Vajra) are Taoist-derived figures associated with the Three Corpse Worms. However, the two can appear together on the same stone monument or in adjacent positions.
When is the next Koshin day?
Koshin falls once every 60 days according to the traditional Chinese sexagenary calendar (jikkan-junishi combination). In 2026, Koshin days occur roughly in January, March, May, July, September, and November (one to two days each). Exact dates can be found in traditional almanacs.
Where can I get a kukuri-zaru?
They are sold at the offering desk of Yasaka Koshin-do (approx. 300 yen each). After purchasing one, make a vow to restrain one desire, then hang it in the precincts.
How many koshinzuka exist in Japan?
An estimated 40,000+ survive nationwide. They are particularly concentrated in the Kanto region (Saitama, Tokyo, Kanagawa), where Edo-period communities were especially active in organizing Koshin associations.
Are paired Dosojin (sotai Dosojin) effective for matchmaking?
Paired Dosojin are traditionally associated with matchmaking, marital harmony, and fertility, and many are visited as romantic power spots. However, the original function of Dosojin was traveler protection and boundary guarding — the matchmaking aspect was amplified in the Edo period.
