A Mystical Path Through Ancient Cedar Forests
The pilgrimage to Okunoin traditionally begins at Ichi-no-hashi, the First Bridge. From here, a peaceful approach of approximately two kilometers leads through a magnificent cedar forest toward Kūkai’s mausoleum.
Towering cedar trees, many of which are hundreds of years old, line the path. Their immense trunks and dense foliage create a quiet, almost timeless atmosphere. As you walk beneath the trees, the sounds and activity of everyday life gradually seem to disappear.
Along both sides of the approach are believed to be more than 200,000 graves, memorial monuments, and cenotaphs. They commemorate people from every level of Japanese society, including members of the imperial family, feudal lords, samurai warriors, religious figures, artists, and ordinary people.
A Walk Through Japanese History
Among the many memorials are those associated with prominent historical and religious figures, including Hōnen, Shinran, Uesugi Kenshin, Oda Nobunaga, Date Masamune, and Takeda Shingen. There are also memorials connected with the Toyotomi family.
Walking along the Okunoin approach is therefore much more than a religious pilgrimage. It can also be seen as a journey through Japanese history itself. Each monument reflects the beliefs, hopes, and memories of the people who came before.
The sheer number of memorials also demonstrates the enduring importance of Kūkai and Mount Koya as a spiritual destination. The forest, monuments, and sacred buildings together create an atmosphere unlike almost anywhere else in Japan.
Three Bridges on the Journey to the Sacred Realm
The approach to Okunoin includes three important bridges. Each has a symbolic role in the transition from the ordinary world to the sacred realm.
In traditional Japanese culture, rivers were often regarded as boundaries between this world and the world beyond. Crossing a bridge could therefore symbolize leaving behind worldly impurities and entering a sacred space.
Ichi-no-hashi: The Entrance to the Sacred Area
Ichi-no-hashi, or the First Bridge, crosses the Taiden River and marks the traditional entrance to Okunoin. From this point onward, visitors are entering an especially sacred area.
Monks traditionally bow three times when crossing the bridge as a sign of respect. Visitors are also encouraged to pause here, show respect, and begin the approach with a quiet and contemplative mind.
Naka-no-hashi: The Place of Purification
Naka-no-hashi, or the Middle Bridge, was historically associated with ritual purification and is also known as the Hand-Washing Bridge.
Nearby are several places associated with fascinating local traditions, including the Sweating Jizō and the Well of Reflection. According to one old belief, if a person looks into the well and cannot see their reflection, they may have only a short time left to live.
Such legends encourage visitors to reflect on the fragility of life and the importance of appreciating the present moment.
Gobyo-bashi: The Final Gateway
Gobyo-bashi, or the Bridge to the Mausoleum, crosses the Tamagawa River and is also known as Mumyō-bashi, the Bridge of Ignorance.
Crossing this bridge marks the entrance to the most sacred part of Okunoin, where Kūkai’s mausoleum stands. The bridge itself has a strong esoteric Buddhist symbolism. Its 36 wooden planks are traditionally associated with the 36 Buddhist deities, with the entire bridge representing a total of 37 sacred figures.
Visitors are expected to maintain a respectful and quiet attitude after crossing this final bridge.
The Lantern Hall and Kūkai’s Mausoleum
After crossing Gobyo-bashi, visitors first encounter the Tōrō-dō, or Lantern Hall. The interior contains countless lanterns donated by worshippers, creating a peaceful and mysterious atmosphere.
Among these lights is the famous “Unextinguished Flame”, which tradition says has continued burning for approximately 1,000 years. The flame symbolizes the enduring faith and prayers of generations of worshippers.
Chanting of Buddhist sutras and religious ceremonies take place at the Lantern Hall. Visitors can pause here to calm their minds before continuing toward the most sacred destination on the mountain.
The Mausoleum of Kōbō Daishi
Beyond the Lantern Hall lies the Gobyo, the mausoleum of Kōbō Daishi. Surrounded by deep forest and profound silence, it is considered one of the holiest places in Japanese Buddhism.
Visitors come here to pray, express gratitude, and quietly offer their wishes. Even travelers who are not Buddhist often find the atmosphere deeply moving because of the extraordinary combination of ancient forest, architecture, history, and spiritual devotion.
The Belief That Kūkai Still Lives
One of the most distinctive aspects of Okunoin is the belief that Kōbō Daishi continues to live in eternal meditation within his mausoleum.
For this reason, Japanese Buddhists traditionally use the term “Nyūjō,” meaning entering deep meditation, rather than simply saying that Kūkai died. The belief expresses the idea that Kūkai remains spiritually present and continues to offer guidance and salvation to living beings.
The Shōjingu: Offering Meals to Kōbō Daishi
Every day, meals are traditionally offered to Kōbō Daishi twice, once in the morning and once around midday. This ceremony is known as Shōjingu, or the offering of food to the living presence of the master.
The meals are vegetarian Buddhist cuisine, reflecting the long-standing traditions of monastic life on Mount Koya. This daily practice is one of the most tangible expressions of the belief that Kūkai remains spiritually present at Okunoin.
Historic Sites and Cultural Treasures
Okunoin is home to many historic structures and places of worship in addition to Kūkai’s mausoleum.
Among the sites visitors can discover are a sutra repository associated with Ishida Mitsunari, a Goma Hall dedicated to Fudō Myōō, and the Shōtoku-den**, a facility where pilgrims and visitors can rest.
Other sacred sites include the Miroku Stone and Kazatori Jizō. Each has its own religious traditions and legends, adding another layer of depth to the pilgrimage experience.
Rather than rushing directly to the mausoleum, taking time to explore these smaller sacred sites allows visitors to appreciate the spiritual landscape of Okunoin as a whole.
A Magical Night of Lanterns: Mantō Kuyō-e
Every year on August 13, Okunoin hosts the Mantō Kuyō-e Lantern Memorial Service. During this special event, approximately 100,000 candles are lit along the approach from Ichi-no-hashi to Kūkai’s mausoleum.
As darkness falls, the countless flames illuminate the ancient cedar forest and historic monuments. The contrast between the dark forest and thousands of flickering lights creates an extraordinary and almost dreamlike scene.
The event is held to honor and remember ancestors. For visitors, it provides a powerful opportunity to experience one of Japan’s traditional memorial customs and to reflect on the connections between past and present.
Nature and Silence Through the Four Seasons
The appeal of Okunoin extends beyond its religious and historical importance. The surrounding forest changes dramatically with the seasons, offering a different atmosphere throughout the year.
Spring
In spring, fresh green leaves begin to appear among the ancient cedar trees, bringing a sense of renewal to the forest.
Summer
Summer brings deep, vibrant greenery and cool shade beneath the towering trees. The forest provides a peaceful escape from the heat and bustle of everyday life.
Autumn
In autumn, colorful foliage adds warm tones to the approach, creating beautiful scenery alongside the moss-covered stones and historic monuments.
Winter
Winter can transform Okunoin into a quiet world of snow. The white landscape surrounding the dark cedar trunks and ancient stone monuments creates an especially serene and contemplative atmosphere.
Regardless of the season, walking slowly through the forest allows visitors to experience the profound silence and tranquility that have defined Okunoin for centuries.
A Sacred Journey Through Japanese Spiritual Culture
Okunoin is not simply a tourist attraction. It is one of the most important spiritual destinations in Japan and a place where the religious traditions surrounding Kōbō Daishi continue to shape daily life.
The journey begins beneath ancient cedar trees, passes thousands of memorial monuments, crosses symbolic bridges, and eventually reaches the mausoleum of Kūkai. Along the way, visitors encounter stories, legends, rituals, and traditions that have been preserved for centuries.
For international travelers, Okunoin offers a unique opportunity to experience a side of Japan that cannot be understood through architecture and sightseeing alone. The quiet walk through the forest, the countless memorials, the lanterns, and the enduring faith in Kōbō Daishi reveal a profound dimension of Japanese spiritual culture.
When visiting Mount Koya, be sure to make the journey to Okunoin. Take your time, walk quietly through the ancient forest, and allow the atmosphere of this extraordinary sacred site to speak for itself.
