The Mystery of Shrines at Mountain Passes: Sacred Sites at the Boundaries of Travel

Mountain Passes Were Spiritual Barriers Between Worlds

In ancient Japan, mountain passes were recognized not merely as transportation waypoints but as spiritual boundary lines. The gods governing each side of a mountain could differ, and even language and customs sometimes changed across the divide. Crossing a pass was an act of transitioning from one world to another, and travelers needed to purify themselves at the boundary and greet the gods of the new land.

Behind this worldview lies Japan's ancient "boundary faith" (sakai shinko). In Shinto, the spaces between territories — the boundaries — were believed to hold special spiritual power. Village entrances, river crossings, and mountain passes were all considered liminal zones where the mortal world touched the realm beyond. The folklorist Kunio Yanagita noted that passes marked "the edge of the village community," beyond which lay "an unknown world." Under the ancient ritsuryo legal system, provincial borders were frequently set at mountain passes, and barrier stations were established to regulate the movement of people. For example, the boundary between Shinano Province and Kozuke Province on the Tosando road was placed at Usui Pass, and the three great barriers — Fuwa, Suzuka, and Arachi — were all situated at passes as national defense points. Dosojin guardian deities and Sae no Kami boundary gods were enshrined at passes precisely because these protective spirits shielded travelers from evil and prevented intrusions from the spirit realm. Pass shrines were devices that made invisible boundaries visible — markers telling travelers, "Beyond this point lies another world."

The Etymology of "Touge" — A Character Inscribed with Offering and Prayer

The kanji character for "touge" (峠) is not of Chinese origin but a uniquely Japanese creation called a kokuji. Composed of the mountain radical combined with "up" (上) and "down" (下), it succinctly represents the topography of ascending and descending a mountain. However, a deeper meaning lies hidden in the word's origin. The prevailing theory holds that "touge" derives from "tamuke," meaning "to offer." Travelers would offer wildflowers and nusa (sacred cloth strips) to the gods at mountain passes, and this act of "tamuke" became the name for the place itself, gradually evolving into "touge."

The Man'yoshu, compiled in the Nara period, contains numerous poems referencing "Tamuke-yama" (Mount Tamuke), revealing that people of that era practiced tamuke at passes as an everyday act of devotion. Volume nine includes a poem describing the act of breaking grass at a pass to offer it to the gods, vividly capturing this ancient ritual. The famous poem by Sugawara no Michizane — "On this journey, I have no nusa to offer; at Mount Tamuke, may the gods accept these brocade-like autumn leaves instead" — is rooted in this very culture. In other words, the character "峠" itself compresses the entire history of Japanese travel and prayer into a single written form.

The Culture of Tamuke — Concrete Forms of Prayer at Mountain Passes

The tamuke offerings at mountain passes took various forms depending on the region and era. The oldest form involved simply breaking off roadside grass or leaves as an offering. Over time, the custom of hanging strips of paper or cloth (nusa) on tree branches became widespread, and the practice of stacking stones (tsumiishi) also became common across the country.

Let us look at specific examples. At Hakone Pass, place names derived from "tamuke" survive to this day. Along the stone-paved ancient road of Kuragari Pass, which connects Nara and Osaka, multiple small hokora shrines are scattered, still watching over those who walk the path. At Usui Pass in Shinano, Kumano Shrine stands guard, having protected travelers on the Nakasendo highway for centuries. Along the Shikoku Pilgrimage route, numerous passes punctuate the journey — particularly the path to Yokomine-ji Temple on the border of Ehime and Kochi Prefectures, known as "henro-korogashi" (the pilgrim tumbler), the route's most formidable challenge — and pilgrims would chant nenbutsu prayers and press their palms together at each one.

These tamuke offerings were far more than simple wish-making. What is crucial from a folkloristic perspective is that tamuke at passes also functioned as harai — ritual purification. Travelers would transfer their accumulated defilements and misfortunes onto the nusa or stacked stones, leaving them behind at the pass to enter new territory with a cleansed spirit. The mountain pass served as a purification device, absorbing the traveler's spiritual pollution. This concept connects directly to the practice of washing hands at the temizuya before shrine worship today — a manifestation of Shinto's fundamental philosophy of purification.

The Deities Enshrined at Passes — The Roles of Dosojin, Sarutahiko, and Jizo

The gods and Buddhist figures enshrined at mountain passes are diverse, but several stand out as particularly significant. First, Dosojin are guardian deities of boundaries, placed at crossroads, village borders, and mountain passes. Often carved as paired male-and-female stone figures, they were believed to ward off evil spirits while also serving as gods of matchmaking and fertility. In the Azumino region of Nagano Prefecture, hundreds of Dosojin statues have been identified standing at passes and forks in the road, with the total across the prefecture estimated at approximately 1,800.

Next, Sarutahiko no Okami is known from the Kojiki and Nihon Shoki as the god who guided the heavenly grandson during his descent to earth, and was enshrined at passes and crossroads as the "god of guidance." For travelers facing unknown roads, having a deity who could lead them safely was a profound source of reassurance. Sarutahiko is described in the ancient texts as a striking figure with "a nose seven hands long and a stature of seven feet," an extraordinary deity who illuminated heaven and earth. Sarutahiko Shrine in Ise is considered the head shrine of this deity.

After the introduction of Buddhism, Jizo Bosatsu (Ksitigarbha) became widely revered as a guardian of mountain passes. As the bodhisattva who traverses the six realms to save all sentient beings, Jizo was adopted as a protector of travelers and children, with stone statues placed at key points along pass routes. Along the old Hakone highway, many Jizo stone figures still stand in rows, conveying the compassion once shown to weary travelers. In this way, mountain passes became spaces where Shinto and Buddhism naturally fused.

Sacred Pass Sites Across Japan — Notable Examples

Numerous passes throughout Japan retain vivid traces of religious faith. Let us examine several representative examples.

Hatenashi Pass on the Kumano Kodo pilgrimage route, where the Hosshinmon Oji shrine stands, was the final difficult crossing for pilgrims traveling to Kumano. An oji shrine was enshrined at the summit, and crossing this pass meant entering the sacred domain of Kumano Hongu Taisha. It was quite literally a boundary between the sacred and the profane.

Usui Pass sits on the border of Gunma and Nagano Prefectures and has served since antiquity as a critical gateway between eastern and western Japan. Kumano Shrine stands at its summit, and legend tells that Yamato Takeru, during his eastern campaign, looked back from this pass and lamented the loss of his wife with the words "Azuma haya" ("Oh, my beloved wife!") — a story said to be the origin of the word "Azuma" (east) itself.

Suzuka Pass, on the border of Mie and Shiga Prefectures, was known as one of the most dangerous sections of the Tokaido highway. Legends tell of Sakanoue no Tamuramaro slaying demons there, and the worship of Suzuka Gozen, a female deity, persists. Precisely because the pass was perilous — frequented by bandits — travelers offered fervent prayers to the gods and buddhas.

Vanishing Sacred Sites and the Living Spirit of Travel Prayers

The development of automobile roads and tunnels has caused many once-essential mountain pass routes to be forgotten. Since the Meiji era, old highways have been replaced by national roads and bypasses, eliminating the need to cross passes on foot. Yet the pass shrines still quietly exist deep in the mountains, maintained and protected by hikers and mountaineers.

Fascinatingly, pass worship has survived in transformed ways in modern Japan. Were you aware that small shrines are sometimes installed at highway service areas and parking areas? For instance, at the Ebina Service Area on the Tomei Expressway and the Dangozaka Service Area on the Chuo Expressway, small shrines offer prayers for traffic safety. This can be seen as a modern incarnation of pass worship — praying for safety at a rest stop during a journey.

Furthermore, the fact that shrines across Japan perform car purification ceremonies (kuruma-barai) is another phenomenon on the continuum of pass faith. From the traffic safety prayers at Naritasan Shinshoji to the vehicle blessings at Kanda Myojin in Tokyo, the desire to ask the gods for safe travel persists regardless of how transportation evolves. In recent years, movements to restore old pass roads as hiking courses have gained momentum in various regions, and within the boom of ancient road walking, pass shrines are once again attracting attention. These sacred sites at mountain passes continue to narrate — quietly but unmistakably — that for the Japanese people, travel and prayer have always been inseparable.
