Muroji Temple, located in Uda City, Nara Prefecture, is one of Japan’s historic Buddhist temples, renowned for its tranquil mountain setting and deep spiritual atmosphere. It serves as the head temple of the Muroji school of Shingon Buddhism and is affectionately known as “Nyonin Koya,” or “Koya for Women,” because women were traditionally permitted to worship here even when Mount Koya restricted their entry.
Surrounded by forested slopes and steep mountain paths, Muroji has attracted worshippers and visitors for centuries. Its buildings are scattered from the foot of Mount Muro to its middle slopes, blending harmoniously with the natural landscape. The temple preserves precious Heian-period architecture and Buddhist statues, offering a glimpse into Japan’s religious and artistic heritage.
Muroji Temple lies in the eastern part of the Nara Basin, close to the border with Mie Prefecture. The temple grounds extend along the northern bank of the Muro River, a tributary of the Uda River, and climb the slopes of Mount Muro. The arrangement of halls and pagodas creates the impression that the temple is an integral part of the surrounding mountains.
The temple is also famous for its rhododendrons, which bloom beautifully in spring. Together with the forest, stone stairways, and traditional buildings, these flowers create a peaceful landscape that has made Muroji a beloved place of pilgrimage and reflection.
The name “Nyonin Koya” reflects Muroji’s historical openness to female worshippers. In contrast to Mount Koya, where women were once prohibited from entering, Muroji allowed women to visit its sacred grounds. This made it an important spiritual destination for women, particularly during periods when access to other major mountain monasteries was restricted.
Although situated in rugged terrain, the temple welcomed worshippers regardless of gender. Its combination of solemn Buddhist traditions and relative openness helped establish its distinctive place in Japanese religious history. The name “Koya for Women” remains an enduring expression of this tradition.
The Kondo, or Golden Hall, is one of Muroji’s most important buildings. It features a hipped roof covered with wooden shingles and stands on a steep slope using a construction method known as kake-zukuri, in which a building is supported over uneven terrain. This technique is particularly suited to mountain temples.
The main hall dates to the latter half of the ninth century, during the early Heian period, while the worship area at the front was added in 1672. The combination of the original structure and later additions reflects the temple’s long history of religious use and preservation.
The Golden Hall is associated with an important collection of Buddhist images, including the Eleven-Headed Kannon, or Goddess of Mercy, and a Shakyamuni Buddha statue, both designated National Treasures. Other figures include Monju Bosatsu, the bodhisattva of wisdom; Yakushi Nyorai, the Buddha of healing; and Jizo Bosatsu, a bodhisattva who protects travelers and those in need. Statues of the Twelve Heavenly Generals were also arranged in front of the principal images.
Some of these sculptures have since been moved to the temple’s Treasure Hall to help preserve them in a suitable environment and make them available for viewing.
The Eleven-Headed Kannon and Shakyamuni Buddha are believed to date from the ninth century and retain distinctive characteristics of early Heian Buddhist sculpture. The halo behind the Shakyamuni statue depicts the Seven Medicine Buddhas, leading researchers to suggest that the figure may originally have been created as Yakushi Nyorai.
The halo associated with the Jizo Bosatsu statue is also thought to have belonged to a different sculpture before the two were combined. Such details reveal how Buddhist images could be adapted and rearranged over the centuries as temples evolved.
The five-story pagoda is one of Muroji’s most recognizable landmarks. Built in the early Heian period, it is celebrated as Japan’s smallest wooden five-story pagoda and is among the country’s oldest surviving structures of this type. Its elegant proportions and refined craftsmanship make it an outstanding example of traditional Japanese Buddhist architecture.
The pagoda stands approximately 16 meters tall. Its five roofs are relatively similar in size, and its sturdy pillars and gently sloping eaves give it a distinctive appearance. Instead of the more familiar suien, a decorative metal finial resembling flowing water or flames, the top of the pagoda features a vase-shaped ornament called a hōbyō and an umbrella-shaped ornament known as a hōgai. This unusual arrangement sets it apart from many other Japanese pagodas.
According to local tradition, the vase-shaped ornament contains or restrains the dragon deity associated with the Muro area. The story reflects the longstanding relationship between the temple, mountain worship, and beliefs surrounding water and dragons.
The pagoda has undergone several repairs throughout its history. In 1998, a powerful typhoon caused a large tree to fall onto the structure, inflicting serious damage. Fortunately, its central structural elements, including the heart pillar, remained intact, and restoration work was carried out from 1999 to 2000.
During the restoration project, researchers from the Nara National Research Institute for Cultural Properties examined the timber used in the pagoda. Their findings indicated that the wood had been felled around 794, supporting the theory that the pagoda was constructed around 800.
The origins of Muroji Temple date to the Hōki era, between 770 and 781, toward the end of the Nara period. According to tradition, the high-ranking monk Kenkei, who was associated with Kofukuji Temple, performed a Buddhist longevity ritual in this area to pray for the recovery of the crown prince, who later became Emperor Kanmu. After the ritual was believed to have produced a favorable result, the establishment of a temple was ordered.
Muroji developed as a center for Buddhist learning and ascetic practice, influenced by both the Tendai and Shingon traditions. The monk Shuen, who had connections with Saicho, the founder of Japanese Tendai Buddhism, played a role in its religious history. Monks such as Shintai, a disciple of Kukai, the founder of Shingon Buddhism in Japan, also entered the temple community.
These connections helped shape Muroji’s distinctive religious character, combining Buddhist scholarship with the demanding practices associated with mountain monasteries.
Throughout the medieval period, Muroji remained a subordinate temple of Kofukuji. Its circumstances changed during the Edo period, when the temple received support from the monk Ryuko of Gokoin. In 1694, it became a Shingon Buddhist temple.
The following year, Keisho-in, the mother of Tokugawa Tsunayoshi, donated 2,000 gold coins to support repairs to the temple buildings. This patronage helped preserve the complex and its important religious structures.
In 1964, Muroji became independent from the Shingon Buzan school. Today, it serves as the head temple of the Muroji school of Shingon Buddhism and continues to welcome pilgrims, history enthusiasts, and visitors drawn to its architecture and natural surroundings.
Beyond the main temple grounds lies a cave known as Ryuketsu, traditionally believed to be the dwelling place of a dragon deity. Nearby, Muro Ryuketsu Shrine has long been associated with this ancient belief.
Historical records indicate that rituals praying for rain and the cessation of rain were performed at this sacred site by the Heian period. Set among dramatic rock formations and ravines shaped by the region’s volcanic geology, the shrine preserves a fascinating tradition linking nature, water, and spiritual power.
The approach to Muroji begins at a beautiful vermilion-lacquered taiko bridge. After crossing it, visitors first encounter the temple’s administrative and residential complex, known as the Honbo. Following the approach path to the right leads to the Nio Gate, a modern reconstruction guarded by traditional Buddhist guardian figures.
Passing through the gate brings visitors into the heart of the sacred grounds, where stone steps wind upward among ancient trees and historic buildings.
One of the first challenges is climbing the steep stone staircase known as Yoroizaka, or “Armor Slope.” At the top stands the Kondo, the National Treasure Golden Hall, while Mirokudo Hall is located to the left. Mirokudo dates to the Kamakura period and is designated an Important Cultural Property, although it was modified during the Edo period.
Mirokudo houses a standing statue of Miroku Bosatsu, the bodhisattva associated with the future Buddha. The hall and its sculpture provide further insight into the Buddhist traditions that flourished at this mountain sanctuary.
Continuing up the stone steps brings visitors to the main hall, also known as the Kanjodo, or Initiation Hall. Dating to the Kamakura period, it is designated a National Treasure and enshrines a seated image of Nyoirin Kannon as its principal object of worship.
The building has an irimoya-style roof covered with cypress bark. Its name, Kanjodo, refers to kanjo, an initiation ceremony used in esoteric Buddhism. The hall houses a seated statue of Nyoirin Kannon, designated an Important Cultural Property, along with mandalas representing the two realms of esoteric Buddhist cosmology.
From beside the five-story pagoda, a flight of approximately 400 stone steps climbs toward the inner sanctuary. At the top stands Miedo Hall, a structure from the early Muromachi period and an Important Cultural Property. It enshrines Kobo Daishi Kukai, the influential monk who established Shingon Buddhism in Japan.
Miedo is one of the older surviving buildings among the many halls dedicated to Kukai throughout Japan. Its secluded mountain setting creates a particularly contemplative atmosphere.
A further area beyond Miedo serves as a place for religious training and ascetic practice. It is not open to general visitors.
The temple grounds contain several other historic structures and monuments. These include a five-ring stone pagoda traditionally associated with the grave of Kitabatake Chikafusa, an important figure of the medieval period. The monument is designated an Important Cultural Property.
Mirokudo Hall is another notable building, with a history extending back to the early Kamakura period. Its later alterations reflect the changes the temple complex underwent as religious needs and architectural styles evolved.
Muroji’s Treasure Hall was built in 2019 to provide a suitable environment for preserving and displaying the temple’s National Treasures and Important Cultural Properties. It presents a number of significant Buddhist sculptures, including the standing Eleven-Headed Kannon, the seated Shakyamuni Buddha, the standing Jizo Bosatsu, and some of the Twelve Heavenly Generals. These works were formerly enshrined in the Golden Hall and Mirokudo Hall.
The collection offers visitors an opportunity to appreciate the artistry and religious significance of sculptures that have been preserved at Muroji for centuries.
Other structures within the grounds include Yakushido Hall, associated with the sixth station of the Mount Muro Eighty-Eight Sacred Sites pilgrimage; the Oda Mausoleum, traditionally identified as the tomb of Oda Nobukatsu; and memorial structures dedicated to Shuen, Keisho-in, and the Honjo family.
Visitors can also see the worship hall of Tenjin Shrine, a Benzaiten shrine, and the Jotodo, a hall used for memorial tablets. Together, these buildings reflect the diverse religious traditions and historical connections that have shaped the temple over time.
Muroji’s appeal extends beyond its architecture and Buddhist treasures. The surrounding natural landscape changes dramatically with the seasons. Cherry blossoms brighten the grounds in spring, fresh green foliage fills the forest in early summer, and autumn brings vibrant shades of red and gold.
Autumn foliage is especially popular, creating a striking contrast with the pagoda and traditional wooden buildings. In winter, snow may transform the temple into a quiet mountain scene. As visitors climb the stone steps and follow the paths through the forest, each turn reveals a different view of the temple’s harmonious relationship with nature.
Muroji Temple can be reached from Muroguchiono Station on the Kintetsu Osaka Line. From the station, take a bus toward the temple area. The journey takes approximately 15 minutes, followed by a walk to the temple. Depending on the bus stop used, the final walk may take around 5 to 15 minutes.
Visitors arriving by car can use the parking facilities near the temple. As the temple is located in a mountainous area, the stone steps and paths can become slippery during winter or in bad weather. Comfortable walking shoes and care on uneven surfaces are recommended.
Muroji Temple is valued not only for its long history and outstanding Buddhist architecture, but also for the quiet atmosphere of its forested mountain setting. Its National Treasures, Important Cultural Properties, seasonal flowers, and connections with the ancient worship of dragon deities make it one of Nara Prefecture’s most distinctive sacred sites.
Here, the traditions of esoteric Buddhism remain closely connected with the surrounding mountains and forests. For travelers seeking Japanese religious history, traditional architecture, or a peaceful retreat into nature, Muroji offers a memorable encounter with the spiritual heritage of Japan.
