Niutsuhime Shrine, located in the peaceful Amano Basin of Katsuragi Town, Ito District, Wakayama Prefecture, is one of the most important ancient Shinto shrines in the Kii Peninsula. Known as the Ichinomiya, or highest-ranking shrine, of the former Kii Province, it has been worshipped for more than 1,700 years.
Niutsuhime Shrine is also regarded as the head shrine of approximately 180 shrines throughout Japan dedicated to Niutsuhime-no-Okami. The shrine stands at an elevation of approximately 450 meters in Amano, a quiet mountain basin surrounded by forested peaks.
The scenery around the shrine has long been considered sacred. Japanese writer Shirasu Masako described Amano in her book Kakurezato as a “dream garden opening in a corner of heaven,” reflecting the area’s peaceful beauty and spiritual atmosphere.
Niutsuhime Shrine has a particularly close historical relationship with Mount Koya, the center of Japanese Shingon Buddhism. Together with Mount Koya and other sacred locations in the Kii Mountains, the shrine forms part of the UNESCO World Heritage property “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.”
Kobo Daishi Kukai and the Founding of Mount Koya
The history of Niutsuhime Shrine cannot be separated from the story of Kobo Daishi Kukai, the founder of Shingon Buddhism in Japan and one of the country’s most revered Buddhist figures.
According to tradition, Kukai was searching for an appropriate location to establish a center for the practice of Esoteric Buddhism when he encountered a hunter accompanied by two dogs, one white and one black. The hunter is said to have been the manifestation of Takano Mikono-Okami, the deity enshrined in the shrine’s second sanctuary.
The hunter guided Kukai toward Mount Koya. According to the legend, Kukai later encountered Niutsuhime-no-Okami in Amano and received permission to use the land of Mount Koya for his religious activities.
Through this legendary encounter, Niutsuhime-no-Okami became closely associated with the protection of Mount Koya. This relationship helped create a unique religious tradition in which Shinto and Buddhism existed together.
For centuries, pilgrims traveling to Mount Koya traditionally visited Niutsuhime Shrine before continuing into the mountains. The Futatsu Torii, or Two Torii Gates, along the Koya Sankeimichi pilgrimage route still preserve the memory of this traditional pilgrimage.
A Goddess Who Protects People from Misfortune
The principal deity, Niutsuhime-no-Okami, has long been worshipped as a goddess who protects people from disasters, illness, and misfortune.
The character “Ni” in her name is associated with cinnabar, a mineral historically connected with the color red. In ancient Japan, red was believed to possess protective and purifying powers and was often used to ward off evil.
As a result, Niutsuhime-no-Okami came to be revered as a powerful protective deity who safeguards people’s lives, drives away misfortune, and guides them toward happiness.
According to tradition, her divine power was believed to have protected Japan during the Mongol invasions of the 13th century. Her reputation as a protective deity subsequently became even stronger among members of the imperial court, samurai families, and other worshippers.
Today, visitors continue to come from throughout Japan to pray for protection from misfortune, good fortune, health, and a safe future.
The Four Sacred Deities of Amano
Niutsuhime Shrine enshrines four principal deities and is traditionally known as the Amano Shisho Myojin, or the Four Sacred Deities of Amano.
First Sanctuary: Niutsuhime-no-Okami
Niutsuhime-no-Okami is the principal deity of the shrine and is revered as a powerful goddess of protection. She is also regarded as the guardian deity of Mount Koya.
Second Sanctuary: Takano Mikono-Okami
Takano Mikono-Okami is traditionally believed to have guided Kukai toward Mount Koya. The deity is also known as Kariba Myojin, or the Hunting Ground Deity.
Third Sanctuary: Ogetsuhime-no-Okami
Ogetsuhime-no-Okami is associated with food, agriculture, and abundant harvests. As a deity who supports human life through food and farming, this kami has long been worshipped for prosperity and agricultural abundance.
Fourth Sanctuary: Ichikishimahime-no-Okami
Ichikishimahime-no-Okami is associated with water, artistic performance, and financial prosperity. She is also widely known as one of the deities enshrined at Itsukushima Shrine.
A Shrine Preserving the History of Shinto and Buddhism
One of the most fascinating aspects of Niutsuhime Shrine is the way it preserves the history of Shinbutsu Shugo, the traditional blending of Shinto and Buddhism.
Before the Meiji government’s policy of separating Shinto and Buddhism, the shrine precinct contained numerous Buddhist buildings, including a pagoda, a hall dedicated to Kobo Daishi, a hall dedicated to Fudo Myoo, and a hall used for Buddhist fire rituals.
These religious facilities formed a larger sacred landscape connected closely with Mount Koya. Although many of the Buddhist buildings were removed following the Meiji-era separation of Shinto and Buddhism, archaeological remains and historical traces survive.
The entire shrine precinct is protected as an Important Historic Site of Japan, allowing visitors to explore the remains of this distinctive religious tradition.
The Outer Torii: Entrance to the Sacred Realm
The Outer Torii Gate at the entrance to the shrine is a distinctive example of a Ryobu Torii. This unusual type of torii reflects the historical connection between Shinto and Esoteric Buddhism.
The form is traditionally associated with the two mandalas of Shingon Buddhism, the Diamond Realm and Womb Realm. Passing beneath the gate therefore provides a symbolic transition from the ordinary world into sacred space.
Rinkyo Bridge: A Bridge for the Gods
One of the most beautiful features of the shrine is Rinkyo Bridge, an elegant vermilion arched bridge spanning Kagami Pond.
The bridge is traditionally regarded as a sacred bridge used by the deities rather than an ordinary crossing for everyday use. The current bridge is said to have been donated by Yodo-dono, the wife of Toyotomi Hideyoshi.
The vivid vermilion bridge reflected in the calm waters of the pond creates one of the most memorable views at Niutsuhime Shrine.
The Mysterious Kagami Pond
Behind Rinkyo Bridge lies Kagami Pond, or Mirror Pond, which is associated with an intriguing Japanese legend.
According to tradition, Yao Bikuni, a legendary woman said to have gained eternal youth after eating the flesh of a mermaid, placed a sacred mirror on a small island in the pond.
The reflections of the shrine buildings, trees, and surrounding landscape on the surface of the pond create a peaceful and almost dreamlike atmosphere.
Purification Bridge and the Middle Torii
A bridge called the Misogi Bridge crosses the stream known as Misogigawa within the shrine grounds. The bridge is associated with purification rituals before approaching the sacred halls.
According to tradition, sacred purification objects and cinnabar, which has a close symbolic connection with Niutsuhime-no-Okami, are kept within the ornamental finials of the bridge.
Beyond the bridge stands another vermilion Ryobu Torii. Its impressive appearance symbolizes the long-standing spiritual relationship between Niutsuhime Shrine and Mount Koya.
The National Treasure-Quality Rojo Gate
Standing in front of the main sanctuaries is the magnificent Rojo Gate, a representative example of Muromachi-period architecture. The gate was constructed in 1499 and features brilliant vermilion coloring and a traditional cypress-bark roof.
Its elegant three-bay structure and imposing appearance make it an appropriate entrance to the sacred inner precinct. The gate is designated as an Important Cultural Property of Japan and is also included within the UNESCO World Heritage site.
Today, visitors normally begin their formal worship from in front of this historic gate.
The Four Main Sanctuaries
Beyond the Rojo Gate, four main sanctuary buildings stand side by side. Together they are known as the Shisho Myojin, or Four Sacred Deities.
Each sanctuary enshrines one of the four principal deities: Niutsuhime-no-Okami, Takano Mikono-Okami, Ogetsuhime-no-Okami, and Ichikishimahime-no-Okami.
The buildings are constructed in the traditional Kasuga-zukuri architectural style, featuring cypress-bark roofs. They are among the largest examples of this architectural style and are designated as Important Cultural Properties.
The present buildings were primarily reconstructed during the Muromachi period. Their dignified appearance reflects the shrine’s long history of more than 1,700 years of worship.
Remains of Shugendo and Mountain Asceticism
Niutsuhime Shrine is important not only in Shinto but also in the history of Shugendo, a Japanese tradition of mountain asceticism.
Historic monuments within the grounds include the Monuments of Omine Practitioners, a stone monument associated with Buddhist mantra practices, and a stone shrine associated with the pilgrimage route.
The monuments dedicated to Omine practitioners include groups of stone gorinto, or five-element pagodas, dating from the Kamakura and Muromachi periods. They provide valuable evidence of the religious practitioners who once traveled through these mountains in search of spiritual training.
Traces of the Shinto-Buddhist Tradition
Visitors can also find the remains of a two-story Buddhist pagoda and the former Kobo Daishi Hall. In earlier centuries, the shrine grounds included numerous Buddhist structures, such as a pagoda, Fudo Hall, and sutra repository.
Although most of these buildings disappeared following the Meiji-era separation of Shinto and Buddhism, the surviving foundations and archaeological remains help explain how Shinto and Buddhist beliefs once existed side by side.
These remains make Niutsuhime Shrine a particularly valuable place for understanding the religious history of medieval Japan.
The Futatsu Torii and Hacho-zaka Pilgrimage Path
Behind the shrine, a historic pilgrimage route leads toward the Koya Sankeimichi, the ancient path connecting the sacred sites of the region with Mount Koya.
At an important junction stand the Futatsu Torii, or Two Torii Gates. The two stone gates are traditionally associated with Niutsuhime-no-Okami and Takano Mikono-Okami and served as an important place of worship for pilgrims traveling toward Mount Koya.
From the Futatsu Torii, the Hacho-zaka path descends toward the shrine. Pilgrims heading to Mount Koya once traveled along this route, making it possible for modern visitors to experience part of the historic pilgrimage landscape.
Niutsuhime Shrine as a Center of Shugendo
Niutsuhime Shrine developed not only as a Shinto sanctuary but also as an important center for Shugendo mountain practices.
Practitioners associated with the Katsuragi and Omine mountain traditions came to this region to train in the mountains and pray for divine protection before undertaking difficult ascetic journeys.
The surviving monuments, stone shrines, and remains of former Buddhist buildings provide a fascinating glimpse into the religious world of medieval Japan, when pilgrims, Buddhist monks, and mountain ascetics traveled through the Kii Mountains.
A Gateway to the Mount Koya Pilgrimage
The Futatsu Torii on the Koya Sankeimichi is one of the most important reminders of the traditional relationship between Niutsuhime Shrine and Mount Koya.
The torii are associated with worship from a distance, and pilgrims historically descended toward the shrine to pray before continuing their journey toward Mount Koya.
From the area around the two torii, visitors can enjoy expansive views across the peaceful Amano Basin. The landscape of rice fields, forests, and mountain villages provides a beautiful setting for experiencing the traditional pilgrimage culture of the Kii Mountains.
Traditional Festivals Throughout the Seasons
Ota Festival
The Ota Festival, held each January, is a traditional agricultural ceremony in which prayers are offered for a plentiful harvest.
The festival is believed to have a history extending back to the Heian period. Traditional dances and performances are presented as part of the ceremony, making it an important example of the region’s traditional folk culture.
Hanamori Festival
Held in April, the Hanamori Festival celebrates the arrival of spring. Seasonal flowers are displayed in bamboo containers along the approach, transforming the shrine grounds into a colorful and elegant setting.
Children from the local community perform the traditional Urayasu no Mai, while a ceremonial procession led by Sarutahiko, a deity wearing a distinctive tengu-like mask, makes its way through the shrine grounds.
Traditional gagaku court music and taiko performances add to the atmosphere, creating a scene reminiscent of a traditional Japanese historical painting.
World Heritage Status and Cultural Treasures
Niutsuhime Shrine contains numerous historically important buildings and cultural treasures. The shrine’s main sanctuaries, Rojo Gate, and surrounding sacred landscape form part of the UNESCO World Heritage property “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.”
Among the shrine’s important treasures is the Gindou Hirumaki Tachi Koshirae, an exquisite sword mounting associated with the late Heian period. The shrine also preserves important medieval objects, including wooden guardian lion-dog sculptures, portable shrines, a gilt-bronze biwa, and traditional swords.
These objects provide valuable insight into the religious traditions, craftsmanship, and cultural history that developed around the shrine over many centuries.
The Peaceful Landscape of Amano
The village of Amano, where Niutsuhime Shrine stands, is known for its beautiful traditional rural landscape. The area has been selected as one of Japan’s “100 Rural Landscapes of Japan”, recognizing the harmony between agriculture, villages, forests, and mountains.
Each season brings a different atmosphere. Fresh green leaves appear in spring, while fireflies can be seen around early summer. In autumn, golden rice fields stretch across the basin, and winter brings crisp air and remarkable tranquility.
This landscape has supported the spiritual life of Mount Koya for centuries while preserving a glimpse of the traditional Japanese countryside.
A Sacred Link Between Shinto, Buddhism, and Mount Koya
Niutsuhime Shrine is far more than a historic Shinto shrine. It is a sacred place where the history of Shinto, Buddhism, Shugendo, pilgrimage, and the spiritual traditions of Mount Koya come together.
From the legendary encounter between Kukai and the guardian deities of Mount Koya to the elegant vermilion bridges and historic sanctuary buildings, every part of the shrine reflects a long and fascinating religious history.
For international travelers exploring the Kii Peninsula, a visit to Niutsuhime Shrine offers an opportunity to experience a quieter side of Japan’s spiritual heritage. Walking through the peaceful Amano Basin, passing beneath the traditional torii gates, and viewing the historic shrine buildings provides a deeper understanding of the cultural landscape that surrounds Mount Koya.
Surrounded by mountains, rice fields, forests, and centuries of sacred traditions, Niutsuhime Shrine is a remarkable destination where nature, history, and spirituality continue to live together.
