The Great Cedar of Mushikawa: A 1,200-Year Sentinel of Echigo
Tucked into the snow country of Niigata Prefecture, in a quiet corner of Joetsu City's Urakawara district, stands one of Japan's most extraordinary trees. The Great Cedar of Mushikawa (Mushikawa no Ōsugi) rises some thirty meters into the sky, its trunk so vast that several adults linking arms still cannot encircle it. For more than twelve centuries, this living monument has watched over the surrounding rice fields, weathered the heavy winters of the Japan Sea coast, and served as the sacred tree of the small Hakusan Shrine at its base. Designated a National Natural Monument in 1937, it remains one of the largest and most majestic cedars in all of Japan—and a destination that rewards travellers willing to venture beyond the well-trodden tourist trail.
A Living Witness to Japanese History
Local tradition holds that the cedar was already growing here when Hakusan Shrine was founded in the Heian period (794–1185). If the estimated age of more than 1,200 years is accurate, the tree was a sapling around the time the imperial capital moved to Kyoto, and it would have been a substantial trunk by the days of the samurai who built castles in the surrounding mountains. Generation after generation of villagers in Mushikawa have considered it their guardian, weaving it into festivals, prayers, and the rhythm of agricultural life.
The cedar's resilience is itself a story of survival. During a great snowstorm in the Edo period, one of its enormous main branches snapped under the weight of the snow, leaving a deep cavity in the trunk. For many years this hollow was protected by sheets of copper, a familiar sight to long-time visitors. In 2017, after careful restoration work led by certified tree doctors and the local volunteer group dedicated to the tree's care, the copper was replaced with strips of cedar bark—a gentler, more natural shield that has helped the tree's vitality recover.
Why This Tree Was Designated a National Natural Monument
On 17 April 1937, the then Ministry of Education designated the Great Cedar of Mushikawa as a National Natural Monument under Japan's cultural property system. The official designation document describes it succinctly: a vigorous giant cedar with a trunk circumference of approximately 10.6 metres at chest height, ranking among the most outstanding specimens of its species in the country.
Three qualities set this tree apart. First, sheer scale: with a girth of roughly 10.6 to 10.7 metres and a height around 30 metres, it stands among the largest cedars on the entire Japan Sea side of the country. Second, its dramatic form: rather than rising as a single straight column, the tree spreads massive lateral limbs that reach about 27 metres east-to-west and 20 metres north-to-south, filling the shrine precinct like a living canopy. Third, its botanical character. The cedar is a classic example of urasugi, the "back-side cedar" of the Japan Sea region—a variety shaped by deep snow and abundant moisture, whose drooping branches root readily into the soil and whose form is more sculptural than the slender, upright omotesugi of the Pacific coast. Together these features make the tree both a botanical specimen of national importance and a cultural touchstone for the region.
Highlights for the Visitor
Stepping onto the shrine grounds, the first impression is one of scale recalibrated. The small wooden hall of Hakusan Shrine sits almost dwarfed at the foot of the cedar, its roof barely reaching the lowest spreading limbs. Visitors often describe a sense of standing before a presence rather than a tree.
A wooden boardwalk circles the cedar, allowing close inspection without compacting the soil around its roots. Walking the perimeter reveals different aspects of the tree: from one side, the famous L-shaped silhouette where the great branches angle outward and upward; from another, the patched trunk where centuries of storms have left their mark; from below, a vertiginous view straight up the columnar limbs that themselves are as thick as ordinary mature trees. A soft carpet of moss spreads across much of the surrounding ground, lending the precinct a quiet, cathedral-like atmosphere even on bright days.
The tree has long been considered a power spot, and many visitors come to offer quiet prayers for health and longevity—an entirely fitting wish at the foot of something that has lived through more than a millennium of Japanese winters. The most photogenic times of year are the lush green of early summer, when the moss is at its most vivid, and the deep snows of January and February, when the cedar stands like a black mountain against the white landscape.
Each spring, on 29 April, residents of the area gather to celebrate the spring festival of Hakusan Shrine. A massive shimenawa sacred rope, distinguished by its decorative knot work, is hand-woven by the community and ritually placed around the tree—an unbroken thread of devotion that has tied generations of villagers to their ancient guardian.
Visiting Information
The cedar stands within the precincts of Hakusan Shrine in Mushikawa, and the grounds are open at all times without an admission fee. Visitors are asked to walk only on the prepared boardwalk, to refrain from touching or climbing the tree, and to observe the quiet etiquette appropriate to a sacred site. There is a small parking area with space for around ten vehicles, and a public restroom is available on site.
Access by train is unusually convenient for a cultural property of this kind. The Hokuhoku Line of Hokuetsu Express, which runs between Echigo-Yuzawa and the coast, has a station named after the very tree itself: Mushigawa-Ōsugi Station. From the station it is a pleasant walk of about ten minutes through rice fields and a quiet residential lane to the shrine. Travellers driving from the Hokuriku Expressway can reach the site in roughly thirty minutes from either the Joetsu or Kakizaki interchange.
Winter visits require some planning. The Urakawara area sees substantial snowfall from late December through March, and the boardwalk may be partly covered. Sturdy waterproof boots and appropriate warm clothing are essential during this season, but the snowscape rewards those who come prepared.
Around the Great Cedar
The Mushikawa cedar is a natural anchor for a half-day or full-day exploration of the inland Joetsu countryside, an area still relatively undiscovered by international travellers.
Just one stop away on the Hokuhoku Line is Uragawara Station, the heart of the old Urakawara village, where small soba shops and farm stands offer dishes made with locally grown buckwheat and seasonal mountain vegetables. A short drive south leads to the Yasuzuka district, known for its powdery snow, traditional kayabuki thatched-roof landscapes, and shops selling miso pickles, oyaki stuffed dumplings, and the local cloudy doburoku sake. Further into the mountains, hiking trails lead to the ruins of Ōma Castle, a small mountain fortress that once guarded this corner of Echigo Province.
Travellers interested in rural architecture should not miss the Hayashi Tominaga Residence, a Meiji-era estate built in 1883 with a celebrated dry landscape garden carpeted in cedar moss. For those continuing toward the coast, Joetsu's Naoetsu and Takada districts offer the historic Takada Castle Park, the Joetsu City Museum of History, and a number of preserved gangi covered arcades that protect winter pedestrians from snowfall.

Q&A
- How old is the Great Cedar of Mushikawa, and how is its age estimated?
- The tree is generally said to be more than 1,200 years old, an estimate based on its trunk circumference, growth rates of comparable cedars, and the local tradition that it was already standing when Hakusan Shrine was founded in the Heian period. As is true of many ancient cedars, an exact age cannot be determined without core sampling, which is avoided to protect the tree's health.
- Is there an admission fee, and when is the best time to visit?
- Admission is free, and the grounds are open all year round. The most rewarding seasons are late April to early June, when fresh greenery and moss are at their best and the spring festival takes place on 29 April, and the deep winter months when the snowy landscape transforms the precinct.
- Can the tree be reached by public transport from major cities?
- Yes. From Tokyo, take the Joetsu Shinkansen to Echigo-Yuzawa Station, then transfer to the Hokuhoku Line and ride to Mushigawa-Ōsugi Station, named directly after the tree. The cedar is about a ten-minute walk from the station.
- Why does the trunk show patches and what looked like copper plating?
- A great branch was lost during a heavy snowstorm in the Edo period, leaving a hollow in the trunk. For decades the cavity was protected with copper sheeting, but in 2017 the local conservation group, working with certified tree doctors, replaced the metal with strips of cedar bark to encourage natural recovery.
- Are visitors allowed to touch the tree or pray at the shrine?
- Touching or climbing the cedar is not permitted, as the trunk and roots are protected for conservation. Visitors are most welcome to offer prayers at the small Hakusan Shrine in front of the tree, following the customary etiquette of a brief bow, two claps, a silent prayer, and a final bow.
