Murō-ji Mieidō: The Mountain Sanctuary of Kōbō Daishi at the "Women's Kōya"
Muroji Temple Goei-Do Hall (室生寺御影堂, Murōji Mieidō) is an early Muromachi period Buddhist hall in Muro, Uda City, Nara Prefecture, designated an Important Cultural Property in 1911.
Hidden deep within the cedar-clad mountains of eastern Nara Prefecture stands a small, extraordinary wooden hall that few international travelers ever encounter. The Mieidō (御影堂) of Murō-ji Temple, perched at the summit of nearly seven hundred stone steps in the innermost sanctuary of this ancient mountain temple, is a designated Important Cultural Property of Japan. Built in the early Muromachi period to enshrine the venerated image of Kōbō Daishi, Kūkai, the founder of Shingon Buddhism, it is one of the oldest Daishidō halls surviving anywhere in Japan, and its unusual roof form makes it a unique treasure of Japanese architectural history.
A pilgrimage to this hall is a journey not only through rhododendron-filled forests and across moss-covered stones, but through more than twelve centuries of faith, devotion, and the quiet history of a temple that welcomed women when so many other sacred mountains would not.
About Murō-ji and Its Mieidō
Murō-ji Temple is the head temple of the Murō-ji branch of Shingon Buddhism, founded in the late Nara period (around the 770s–780s) on the slopes of sacred Mount Murō. According to temple tradition, the eminent Kōfuku-ji monk Kenkyō (賢憬) performed rituals for the recovery from illness of Crown Prince Yamabe, the future Emperor Kanmu, and the temple was subsequently established here in gratitude. Throughout the Heian period, the mountain served as a center of rigorous Buddhist practice and scholarship.
The temple later became beloved as Nyonin Kōya, or "Women's Kōya." While Kōya-san in Wakayama strictly forbade women entry for centuries, Murō-ji welcomed female pilgrims, becoming one of the few high-status Shingon temples accessible to women. This open-hearted tradition continues to be part of the temple's identity today.
The Mieidō stands at the Okunoin, the innermost sanctuary, at the end of a steep climb up hundreds of stone steps. It is a small, three-bay-square hall built in the hōgyō-zukuri (tented pyramidal roof) style, with a distinctive thick wooden board step-roof topped by a stone rosette at the apex. Inside is enshrined a seated statue of Kōbō Daishi depicting him at age 42, which is traditionally opened for public veneration only on the 21st of each month, the day commemorating Kūkai's passing into eternal meditation.
Why the Mieidō Was Designated an Important Cultural Property
The Mieidō was designated a national Important Cultural Property in recognition of both its architectural rarity and its historical significance within the Shingon tradition. Several features make it exceptional.
First, the building follows an architectural style said to have been transmitted directly from the Mieidō of Kōya-san, the spiritual headquarters of Shingon Buddhism. While Daishidō halls honoring Kōbō Daishi were built at many temples across Japan, this one preserves an early form of that sacred architecture in a remarkably intact condition. It is counted among the oldest surviving halls of its kind.
Second, the hall's unusual roof construction is, by the temple's own description, without parallel. The thick wooden board step-roof, laid in tiered layers rather than the more common cypress-bark or tile coverings, gives the building a heavy, geometric silhouette quite distinct from other Japanese Buddhist halls. The stone rosette, a disc-like finial, crowning the apex of the pyramidal roof is a further unusual detail. Together these features create a small structure of striking presence, one that architectural historians regard as a rare and valuable specimen.
Third, the hall's remote mountain setting and its continuing role as a living place of worship, rather than a museum piece, help preserve the original spiritual character in which such a hall was meant to be experienced.
Highlights and What to See
The Mieidō itself is usually viewed from the outside, as the inner sanctuary with the Kōbō Daishi image is traditionally open only once a month. Even so, there is much to appreciate from the path and the small plateau on which the hall stands.
Look up at the roof: the stacked planks of wood, weathered to a silvery grey, create a rhythm of horizontal lines that rise gently to the stone rosette at the center. The square plan, with its three bays on each side, gives the hall a compact dignity that contrasts beautifully with the surrounding forest.
Standing near the Mieidō is the Jōtōdō (常燈堂), also known as the Ihaidō or mortuary tablet hall. Built in a cliff-clinging kake-zukuri (stilt-supported) style reminiscent of Kyoto's Kiyomizu-dera, this hall offers dramatic views back down the valley, a reward well earned after the long climb.
Nearby is the Nōkyōsho, where pilgrims can receive a goshuin (temple seal) exclusive to the Okunoin. For those who complete the journey up the stone steps, this stamp becomes a treasured memento of a pilgrimage many Japanese visitors undertake as a spiritual challenge.
The climb itself is part of the experience. The path from the five-story pagoda to the Okunoin rises through a dim, cedar-shaded ravine along some 370 to 400 steep steps, with a total of around 700 steps from the Niō-mon gate. Each step gives way to deeper quiet and a growing sense of having left the ordinary world behind.

Q&A
- How difficult is the climb to the Mieidō?
- The route from the five-story pagoda to the Okunoin involves roughly 370 to 400 steep stone steps, on top of the earlier climb from the main entrance. The overall climb from the Niō-mon gate is often described as around 700 steps. It is strenuous and the steps are uneven, so sturdy walking shoes and plenty of time for breaks are recommended. Visitors not confident in their stamina may prefer to stop at the Kondō or pagoda area, both of which are reached by gentler paths.
- Can I see the statue of Kōbō Daishi inside the Mieidō?
- The statue of Kōbō Daishi at age 42, enshrined within, is traditionally opened to public view on the 21st of each month, the day commemorating Kūkai's entry into eternal meditation. On other days, visitors admire the hall from the outside. For the most current viewing schedule, please check directly with the temple before your visit.
- Why is Murō-ji called "Women's Kōya"?
- For centuries, the main Shingon headquarters at Mount Kōya in Wakayama forbade women from entering. Murō-ji, though belonging to the same Shingon tradition, welcomed women pilgrims. Because of this, it became affectionately known as Nyonin Kōya, the "Kōya-san for Women", and attracted particular devotion from female worshippers throughout the centuries.
- Which path within the precinct leads to the Mieidō?
- The stairway that starts to the left of the five-storied pagoda climbs to the Okunoin, where the Mieidō stands. It is a long ascent from the Nio Gate, so allow time and wear proper shoes. Directions to the temple, opening hours and admission are set out on the Muroji Temple page.
- May I photograph the Mieidō?
- The exterior of the building may be photographed. Nara Prefecture prohibits photographing Buddhist statues and asks that cameras be pointed at nothing other than buildings, plants and scenery, so avoid aiming inside the hall.
