The Gateway to Mount Koya
Jison-in is traditionally said to have been founded in 816 by Kobo Daishi Kukai, the founder of Koyasan and one of the most influential Buddhist figures in Japanese history.
When Kukai established his religious center on Mount Koya, Jison-in was developed at the foot of the mountain as an administrative and lodging facility supporting pilgrims and visitors. Because the summit of Mount Koya could become extremely cold during winter, the lower elevation of Jison-in also provided a more suitable place for religious practice during the colder months.
Jison-in also marks the starting point of the Koyasan Choishimichi Pilgrimage Route, an ancient pilgrimage trail leading to Mount Koya. Along this approximately 20-kilometer route, stone markers called choishi were traditionally placed at intervals of one cho, or approximately 109 meters.
For more than a thousand years, pilgrims have followed these stone markers toward Koyasan. Walking the route today offers travelers an opportunity to experience the landscape and spirituality of an ancient Japanese pilgrimage.
The Story of Kobo Daishi and His Mother
One of the most moving stories associated with Jison-in is the relationship between Kobo Daishi Kukai and his mother, Tamayori Gozen.
When Kukai established his Buddhist community on Mount Koya, the mountain was traditionally regarded as a sacred area where women were not permitted to enter. Kukai’s elderly mother traveled from Sanuki Province, in present-day Kagawa Prefecture, because she wanted to see the sacred mountain where her son had established his religious center.
However, because women were not allowed to enter the mountain sanctuary, she could not travel to the summit. Kukai therefore welcomed his mother to Jison-in at the foot of the mountain, where she spent the final years of her life.
According to tradition, Kukai repeatedly traveled down from Mount Koya to visit his mother. The story says that he came to see her nine times each month. This tradition is believed to be one of the origins of the name Kudoyama, literally meaning “Nine Visits Mountain.”
After his mother’s death, Kukai is said to have learned through a spiritual dream that she had become an incarnation of Maitreya Bodhisattva. He created an image of Maitreya and established a hall to honor both the Buddha and his mother’s spirit.
Because Maitreya is also known as Jison, the temple came to be known as Jison-in. This touching story of a mother’s love and a son’s devotion remains one of the most important elements of the temple’s identity.
Jison-in as “Women’s Koyasan”
Jison-in has long been known as “Women’s Koyasan”.
During periods when women were prohibited from entering the sacred areas of Mount Koya, many female pilgrims came to Jison-in instead. The temple therefore became an important spiritual refuge for women seeking connection with the religious traditions of Koyasan.
Over the centuries, various forms of devotion developed here, particularly prayers for safe childbirth, fertility, healthy children, breastfeeding, and family well-being.
One of the most distinctive sights at the temple today is the collection of breast-shaped ema prayer plaques. These wooden plaques are offered by visitors praying for pregnancy, safe childbirth, successful breastfeeding, healthy child-rearing, and recovery from breast-related illnesses.
This unusual and deeply personal form of devotion has become one of the most recognizable features of Jison-in and provides visitors with insight into the diversity of religious practices in Japan.
Jison-in and Its UNESCO World Heritage Status
In 2004, Jison-in was registered as part of the UNESCO World Heritage property “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.”
The temple’s historic Miroku Hall is also designated as an Important Cultural Property of Japan. Together with the ancient pilgrimage route and surrounding sacred sites, Jison-in demonstrates the cultural and spiritual importance of the Kii Mountain Range.
The temple also preserves a remarkable Buddhist sculpture: the wooden seated statue of Maitreya Buddha, which has been designated a National Treasure of Japan.
The Miroku Hall and National Treasure Maitreya Buddha
The Miroku Hall is the central historic building at Jison-in. Constructed with a traditional hogyo-zukuri pyramidal roof and covered with cypress bark, it is considered one of the oldest surviving wooden structures in Wakayama Prefecture.
Inside the hall is the National Treasure statue of Seated Maitreya Buddha. Created during the early Heian period, the statue is approximately 91 centimeters high and is admired for its distinctive facial features, powerful body, and boldly carved folds of its robes.
Ink inscriptions preserved inside the statue indicate that it was created in 892. Because its date can be established with unusual precision, the sculpture is regarded as an extremely important reference work for the study of early Heian-period Buddhist sculpture.
The statue has been carefully preserved as a hidden Buddha for centuries. Its remarkable state of preservation and limited public viewing make it one of Jison-in’s most precious treasures. The statue is traditionally revealed to the public only once every 21 years.
Highlights Around the Temple Grounds
Tahoto Pagoda, or Dainichi Tower
On the western side of the temple grounds stands a beautiful Tahoto pagoda, also known as the Dainichi Tower because it enshrines Dainichi Nyorai, or Mahavairocana Buddha.
The present structure was rebuilt during the Kan’ei era of the early Edo period. Its balanced proportions and elegant design make it an attractive feature of the temple grounds and an important expression of the architectural traditions associated with Koyasan Buddhism.
Earthen Walls and Historic Gates
The temple is surrounded by traditional tsuiji earthen walls, which have been designated as a cultural property by Wakayama Prefecture. Extending for approximately 250 meters, the walls are considered among the oldest surviving examples of their kind in the prefecture.
The thick earthen walls and historic West Gate and North Gate create a strong sense of history. Walking beside them, visitors can imagine the appearance of the temple complex in earlier centuries.
Around 100 Jizo Statues
Approximately 100 Jizo statues stand around the Miroku Hall. Each has its own expression and appearance, and together they create a peaceful and welcoming atmosphere.
Jizo is a beloved Buddhist figure traditionally associated with protecting children, travelers, and vulnerable people. The quiet rows of statues provide one of the most calming areas of the temple grounds.
Daishi Hall and the Eighty-Eight Sacred Sites of Shikoku
The Daishi Hall, also known as Shikoku Hall, contains a statue of Kobo Daishi along with 88 Buddhist images representing the principal deities of the famous Shikoku 88 Temple Pilgrimage.
Visitors who worship at these images are traditionally believed to receive spiritual benefits comparable to completing the pilgrimage to the 88 temples of Shikoku. For travelers unable to undertake the entire pilgrimage, this offers a fascinating glimpse into one of Japan’s most important pilgrimage traditions.
Miroku Stone and the Stone Seat
The temple grounds contain a sacred stone known as the Miroku Stone. According to tradition, gently touching or stroking the stone with one hand helps visitors form a spiritual connection with Maitreya Buddha.
Another notable feature is a stone seat traditionally associated with Tamayori Gozen, the mother of Kobo Daishi. The stone provides a tangible reminder of the moving story of the mother and son whose relationship is deeply connected with the history of Jison-in.
Breast-Shaped Ema Prayer Plaques
The breast-shaped ema are perhaps the most distinctive expression of faith found at Jison-in.
Visitors offer these wooden plaques with prayers for fertility, safe childbirth, breastfeeding, raising healthy children, and recovery from illness. The many plaques displayed around the temple provide a striking visual expression of personal hopes and prayers.
Binzuru, the Healing Buddha
A statue of Binzuru Sonja, one of the disciples of the Buddha, is another popular attraction.
According to Japanese Buddhist tradition, visitors can pray for healing by gently rubbing the part of the statue corresponding to a part of their own body. The statue has long been associated with prayers for health and recovery.
The Sacred Nagi Tree
A large nagi tree, believed to be more than 350 years old, stands within the temple grounds. It has been designated a natural monument by Kudoyama Town.
Nagi trees have traditionally been regarded as sacred trees in Japan. This ancient tree has silently witnessed generations of pilgrims and worshippers and has become one of the enduring symbols of Jison-in.
The Starting Point of the Koyasan Choishimichi Pilgrimage Route
Jison-in is the starting point of the historic Koyasan Choishimichi, the principal pilgrimage route leading from the foothills to Mount Koya.
The trail extends for approximately 21 kilometers, with stone markers known as choishi traditionally placed every one cho, or approximately 109 meters. The marker at Jison-in is known as the 180-cho marker and marks the beginning of the pilgrimage toward Koyasan.
For more than a thousand years, emperors, retired emperors, warriors, monks, and ordinary pilgrims have traveled this route. Today, it remains a popular destination for hikers and pilgrims who wish to experience Japan’s traditional culture of walking pilgrimage.
A Temple Where Faith and Culture Remain Alive
Jison-in is much more than a historic tourist attraction. It is a living sacred place where more than a thousand years of religious traditions continue to be practiced.
The Jizo statues, Buddhist images, prayer plaques, sacred trees, and traditional buildings all reflect different aspects of Japanese religious culture. The temple’s Shikoku Hall also provides a unique connection with Japan’s pilgrimage traditions beyond the Kii Peninsula.
Regular religious events continue to connect the temple with the local community. In particular, the monthly festival held on the 5th day of each month attracts worshippers and demonstrates how Jison-in remains part of everyday religious life.
Access and Nearby Attractions
Jison-in can be reached in approximately 20 to 30 minutes on foot from Kudoyama Station on the Nankai Koya Line.
The surrounding area contains several other historic sites, including Niutsuhime Shrine and the Koyasan Choishimichi pilgrimage route. Visiting these locations together provides a deeper understanding of the religious history and cultural landscape of Kudoyama.
