Introduction<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

In the coastal city of Atami, Shizuoka Prefecture, a single camphor tree has been standing for more than 2,000 years. This is the Okusu<\/em> \u2014 the Great Camphor Tree of Kinomiya Shrine (\u6765\u5bae\u795e\u793e). With a trunk circumference of approximately 24 meters and a canopy that blankets the entire shrine precinct, it is one of the largest and oldest trees in Japan. Designated as a Special Natural Monument by the Japanese government, this tree is far more than an ecological curiosity. It is a living sanctuary \u2014 a place where people have prayed, grieved, and hoped for millennia. This article explores the ecological, cultural, and spiritual dimensions of the Kinomiya Okusu<\/em>, and why it continues to draw visitors from around the world.<\/p>\n\n\n\n

A Tree That Defies Comprehension<\/h3>\n\n\n\n

The Great Camphor Tree of Kinomiya Shrine is registered in Japan’s Ministry of the Environment survey of giant trees as the second-largest camphor tree (Cinnamomum camphora<\/em>) by trunk circumference in the entire country. The largest, the Kamou no Okusu<\/em> in Kagoshima Prefecture, measures approximately 24.22 meters around \u2014 just barely edging out Kinomiya’s 23.9 meters. At roughly 20 meters tall, with roots that splay dramatically across the ground and a hollow interior large enough to shelter several adults, the tree commands a physical presence that photographs can only partially convey.<\/p>\n\n\n\n

No written records confirm the tree’s exact age, but shrine lore and dendrochronological estimates consistently point to a lifespan exceeding 2,000 years \u2014 meaning this tree was already alive around the time of the early Roman Empire. It has outlasted kingdoms, witnessed the rise of Edo, and continued to grow through Japan’s modernization.<\/p>\n\n\n\n

Japan’s Special Natural Monument: A Rare Designation<\/h3>\n\n\n\n

The Okusu<\/em> was first designated as a Natural Monument in 1924, then elevated to the higher rank of Tokubetsu Tennen Kinenbutsu<\/em> \u2014 Special Natural Monument \u2014 a distinction held by only 75 sites across Japan. For a single living tree to receive this classification is exceptionally rare. The designation reflects not only the tree’s biological uniqueness but also its deep cultural and historical significance to Japanese society.<\/p>\n\n\n\n

Kinomiya Shrine and the Japanese Tradition of Sacred Trees<\/h2>\n\n\n\n

Trees as Divine Vessels in Shinto<\/h3>\n\n\n\n

In Shinto, Japan’s indigenous spiritual tradition, trees are often understood as yorishiro<\/em> (\u4f9d\u308a\u4ee3) \u2014 physical objects through which kami<\/em> (divine spirits) are invited to descend. The older and larger the tree, the more potent its spiritual presence is believed to be. Across Japan, you will find ancient trees wrapped in shimenawa<\/em> (sacred rope), marking them as sites of divine inhabitation.<\/p>\n\n\n\n

Kinomiya Shrine is a particularly striking example of this worldview. According to shrine records, the sacred camphor tree predates the shrine structures themselves \u2014 the Okusu<\/em> was not planted for<\/em> the shrine; rather, the shrine grew around<\/em> the tree. The very name “Kinomiya” (\u6765\u5bae) is believed to derive from “Ki no Miya,” meaning “Shrine of the Tree,” underscoring the fact that the tree itself is the heart of this sacred site.<\/p>\n\n\n\n

The Legend: Walk the Circle, Gain a Year<\/h3>\n\n\n\n

One of the most beloved traditions at Kinomiya Shrine is the ritual of walking silently around the trunk of the Okusu<\/em> once. According to local legend, completing this circuit adds one year to your life. If you hold a wish in your heart and walk the full circle without speaking, it is said the wish will be granted.<\/p>\n\n\n\n

This practice of circumambulating a sacred tree \u2014 walking around it in quiet reverence \u2014 appears throughout Japan’s folk religious traditions. It reflects a belief that the life force of a great tree can be shared with those who approach it with intention. In the context of modern wellness culture, this act closely parallels the principles of Shinrin-yoku<\/em> (\u68ee\u6797\u6d74), or “forest bathing” \u2014 the therapeutic practice of immersing oneself in the presence of trees, which has been validated by Japanese researchers as a measurable reducer of cortisol and blood pressure.<\/p>\n\n\n\n

Ecological Perspective: Why Camphor Trees Live for Millennia<\/h2>\n\n\n\n

The Biology Behind Extraordinary Longevity<\/h3>\n\n\n\n

From an arborist’s perspective \u2014 or that of a Jumokuishi<\/em> (\u6a39\u6728\u533b), Japan’s certified tree doctor \u2014 the camphor tree’s extreme longevity is not accidental. It is the result of several remarkable biological adaptations.<\/p>\n\n\n\n

First and most notably, camphor trees produce sh\u014dn\u014d<\/em> (\u6a1f\u8133), or camphor \u2014 a volatile aromatic compound that functions as a powerful natural preservative. Camphor has been used in East Asian medicine for centuries and was historically extracted from Cinnamomum camphora<\/em> for use as an insect repellent and antiseptic. Within the living tree, this compound actively defends against fungal decay, wood-boring insects, and microbial degradation. It is, in effect, a built-in biocide that protects the tree from within.<\/p>\n\n\n\n

Second, camphor trees possess exceptional b\u014dga<\/em> (\u840c\u82bd) capacity \u2014 the ability to regenerate new growth from dormant buds even after severe damage. Where many tree species would succumb to storm damage, disease, or partial destruction, camphor trees can redirect their energy and rebuild their canopy. This regenerative resilience, combined with the chemical armor of camphor, creates conditions that support lifespans measured not in decades but in millennia.<\/p>\n\n\n\n

The Ecological Role of a Giant Tree<\/h3>\n\n\n\n

The Okusu<\/em> is not merely a cultural artifact \u2014 it is a functioning ecosystem. Its expansive canopy creates a microclimate within the shrine precinct, reducing ground-level temperatures and maintaining humidity levels that support a rich community of ferns, mosses, and lichens along the bark and root surfaces.<\/p>\n\n\n\n

Studies on mature urban trees show that a tree with a canopy area of 100 square meters can transpire up to 400 liters of water per day, cooling surrounding air temperatures by as much as 8\u00b0C. A tree of the Okusu<\/em>‘s scale would far exceed these figures. In an era of growing concern about urban heat islands \u2014 a phenomenon that drives summer temperatures in Japanese cities several degrees above rural baselines \u2014 ancient trees like this one represent irreplaceable natural infrastructure.<\/p>\n\n\n\n

The roots, spreading wide and deep beneath the shrine grounds, also stabilize soil, prevent erosion, and contribute to groundwater recharge. What appears above the surface as a single dramatic trunk is, below ground, an intricate network of living infrastructure quietly sustaining the landscape around it.<\/p>\n\n\n\n

Getting There<\/h3>\n\n\n\n

Kinomiya Shrine is unusually accessible for a site of its spiritual and ecological significance. It lies just a 3-minute walk from Kinomiya Station on the JR It\u014d Line, and roughly 15 to 20 minutes on foot from Atami Station, one of the major stops on the JR T\u014dkaid\u014d Main Line. The combination of easy rail access and Atami’s status as a resort destination means the shrine draws visitors year-round, from domestic day-trippers to international tourists exploring the Izu Peninsula.<\/p>\n\n\n\n

Entry to the shrine precinct and the Okusu<\/em> viewing area is free of charge. A small caf\u00e9 on the grounds offers the rare pleasure of sitting with a drink while gazing at the ancient tree \u2014 a detail that speaks to how the shrine has evolved to welcome contemporary visitors without diminishing its sacred atmosphere.<\/p>\n\n\n\n

How to Observe the Okusu Like an Arborist<\/h3>\n\n\n\n

To truly appreciate the Okusu<\/em>, it helps to look beyond its sheer size and read what the tree’s form reveals about its 2,000-year history. A Jumokuishi<\/em> would note the following:<\/p>\n\n\n\n

    \n
  • Root buttresses<\/strong>: The dramatic surface roots radiating from the base are the tree’s structural response to gravity and wind load \u2014 a visual record of mechanical stress accumulated over centuries.<\/li>\n\n\n\n
  • Internal hollow<\/strong>: The cavity within the lower trunk, large enough to step inside, is common in very old trees. Counterintuitively, this hollowing can increase mechanical stability by distributing stress more efficiently across the shell.<\/li>\n\n\n\n
  • Bark texture<\/strong>: The deeply furrowed, ridged bark characteristic of aged camphor trees is a product of decades of radial growth pressing outward \u2014 each groove a compressed archive of growth rings.<\/li>\n\n\n\n
  • Epiphytic communities<\/strong>: The ferns, mosses, and lichens colonizing the bark and exposed roots represent a miniature ecosystem made possible by the Okusu<\/em>‘s stable humidity and age-roughened surface. Their presence is a sign of environmental health.<\/li>\n<\/ul>\n\n\n\n

    Frequently Asked Questions<\/h2>\n\n\n\n

    Q: How old is the camphor tree at Kinomiya Shrine?<\/strong> A: The tree’s exact age has not been confirmed by modern scientific methods, but shrine tradition and available research consistently estimate its age at over 2,000 years \u2014 placing its origin around the early centuries of the Common Era.<\/p>\n\n\n\n

    Q: Is the Kinomiya Okusu the largest camphor tree in Japan?<\/strong> A: By trunk circumference, it is the second largest, slightly behind the Kamou no Okusu in Kagoshima Prefecture. However, Kinomiya’s tree holds Special Natural Monument status and is arguably the most culturally significant camphor tree in Japan.<\/p>\n\n\n\n

    Q: Does walking around the tree really grant longevity?<\/strong> A: There is no scientific basis for the legend itself, but the act of walking slowly and silently in a natural setting does carry measurable wellness benefits. Research on Shinrin-yoku<\/em> (forest bathing) by Japanese scientists \u2014 including work published by the Nippon Medical School \u2014 has documented reductions in cortisol levels, blood pressure, and heart rate following time spent among trees.<\/p>\n\n\n\n

    Q: Why do camphor trees live so long?<\/strong> A: Camphor trees produce a volatile aromatic compound called camphor (sh\u014dn\u014d<\/em>) that acts as a natural preservative, defending against fungi, bacteria, and insects. Combined with a strong capacity for regenerative growth, these traits allow the species to survive and recover from damage that would kill most other trees.<\/p>\n\n\n\n

    Q: Is the tree still healthy?<\/strong> A: Yes. The Okusu<\/em> continues to produce new foliage each season, indicating active vitality. The shrine and relevant governmental bodies conduct regular tree health assessments and conservation treatments in line with its Special Natural Monument status.<\/p>\n\n\n\n

    Conclusion<\/h2>\n\n\n\n

    The Great Camphor Tree of Kinomiya Shrine has stood through 2,000 years of Japanese history \u2014 through the formation of its ancient capital cities, through centuries of war and peace, through modernization and into the present. It endures not through passivity, but through an extraordinary combination of biological resilience and the deep human care that sacred designation brings.<\/p>\n\n\n\n

    Whether you approach the Okusu<\/em> as a traveler, a tree enthusiast, or someone simply in search of stillness, standing before it offers something rare: the visceral sense of time made tangible.
