Uchiyama Eikyūji was once a renowned Buddhist temple located in Somanouchi-cho, Tenri City, Nara Prefecture. Closely associated with Daijō-in, a major subtemple of Kōfukuji Temple in Nara, it flourished as one of the largest and most prestigious religious complexes in the historic province of Yamato. Its extensive grounds and magnificent buildings made it one of the region’s most impressive temples. However, its long history came to an abrupt end during the anti-Buddhist movement of the early Meiji period in the late 19th century.
Today, the temple ruins lie along the historic Yamanobe-no-Michi Trail, south of Isonokami Jingu Shrine. A pond that once formed part of the temple’s traditional Pure Land garden remains as a reminder of its former beauty. Memorial stones and Buddhist memorial monuments also stand on the site, quietly conveying the historical significance of this once-great religious center.
Uchiyama Eikyūji was established in a tranquil area known as Uchiyama, surrounded by mountains on three sides. Its formal temple name was Kongōjō-in, and its principal object of worship was Amida Buddha, the Buddha associated with the Pure Land of Ultimate Bliss.
Historical documents, including the *Eikyūji Okibumi* and the *Shosha Engishū*, now associated with the Tokyo National Museum’s collections, indicate that the temple was founded between 1113 and 1118 during the reign of Emperor Toba. Its founder was Yorizane, the second head of Daijō-in at Kōfukuji Temple, who established it under imperial patronage. Under the leadership of the third head, Jinpan, additional temple buildings were constructed, and the complex expanded rapidly.
Jinpan was a distinguished Buddhist monk and the son of Fujiwara no Morozane, who served as Grand Minister of State. Jinpan also held the prestigious position of head priest of Kōfukuji Temple. Through his influence, Eikyūji established itself as an important affiliated temple of Daijō-in.
The temple also functioned as a jingūji, a Buddhist temple associated with Isonokami Jingu Shrine. This reflected the traditional Japanese religious practice of combining elements of Buddhism and Shinto, in which kami deities were understood in relation to Buddhist beliefs.
During the medieval period, the grounds contained numerous impressive structures, including a Shingon Buddhist hall, an octagonal pagoda, a hall dedicated to Kichijōten, a Kannon hall, a hall commemorating the temple’s founders, a sutra repository, a bell tower, a bathhouse, and several shrines. The grandeur of the complex earned it the nickname “Nikko of the West,” comparing its splendor with the famous temple and shrine complexes of Nikkō in eastern Japan.
According to the medieval historical chronicle *Taiheiki*, Emperor Go-Daigo is said to have taken refuge at Uchiyama Eikyūji for a short time in 1336. A historic site known as Kayano Gosho, traditionally associated with this episode, remains marked by a monument in the former temple grounds.
By 1585, Uchiyama Eikyūji had 56 subordinate temple residences, making the complex resemble a small town. In 1595, Toyotomi Hideyoshi granted the temple an estate assessed at 971 koku of rice, a measure of agricultural productivity and income. This landholding was maintained throughout the Edo period, providing a substantial economic foundation for the institution.
During this era, the subtemple Jōjō-in gained control of the complex, and Eikyūji became independent of Kōfukuji’s administration as a Shingon Buddhist temple. It received a level of prestige surpassed by only a small number of major temples, including Tōdaiji, Kōfukuji, and Hōryūji. The temple consequently flourished as an important center of religion and culture in the Nara region.
The beginning of the Meiji era in 1868 brought sweeping changes to Japan’s religious institutions. The government’s policy of separating Shinto and Buddhism, followed by the anti-Buddhist movement known as haibutsu kishaku, led to the destruction or closure of numerous Buddhist temples throughout the country.
Uchiyama Eikyūji was among the institutions affected. Ryōchin, the temple’s 28th head priest and a member of the Jōjō-in lineage, left the Buddhist clergy, adopted the name Fujiwara no Ryōchin, and entered service as a Shinto priest at Isonokami Jingu Shrine. Although he attempted to find a way to relocate or preserve the temple, his efforts were unsuccessful. The temple’s lands were confiscated, depriving it of its financial support, and the institution gradually ceased to exist.
The temple’s buildings fell into ruin, and many of its treasures were plundered, dispersed, or lost. The principal Buddhist image was destroyed, and by 1876, most of the temple’s cultural properties had disappeared. Some Buddhist statues and paintings were safeguarded by local residents and the Nakayama family, who were local landowners, but many of these objects were subsequently scattered.
One particularly tragic loss involved the Paintings of the Eight Patriarchs of Shingon Buddhism, attributed to the monk Shinzen. These paintings were transferred to the Museum of Ethnology in Berlin and are believed to have been destroyed during the Battle of Berlin in the final stages of World War II.
Nevertheless, some treasures associated with Eikyūji survive in Japan and have been designated National Treasures or Important Cultural Properties. These surviving works provide valuable evidence of the temple’s former wealth, artistic achievements, and religious importance.
Much of the former temple site is now used as agricultural land. However, several features recall its glorious past, including the pond known as Hon-dō Pond, a stone monument marking Kayano Gosho, a poetry monument commemorating the haiku poet Matsuo Bashō, and memorial monuments dedicated to former head priests.
These modest remains offer a glimpse into the scale of the complex that once stood here. For visitors exploring the Yamanobe-no-Michi Trail, the site provides an opportunity to reflect on the rise and disappearance of one of medieval Yamato’s most influential Buddhist institutions.
Sumiyoshi Shrine, which served as the guardian shrine of Uchiyama Eikyūji, originally stood within the temple grounds. Its main sanctuary was destroyed by arson in 1890, but its worship hall survived. In 1914, the building was relocated to Isonokami Jingu Shrine, where it became the worship hall of Izumo Takeo Shrine, a subordinate shrine within the precincts. The building is now designated a National Treasure of Japan, preserving a rare architectural link to the lost temple complex.
In 2013, the Tenri University Historical Research Society created a reconstruction model of Uchiyama Eikyūji, illustrating how the extensive complex may have appeared at the height of its prosperity. The model was displayed at Tenri City Hall for one year before being preserved at the university.
The year 2014 marked approximately 900 years since the temple’s foundation, bringing renewed attention from researchers and history enthusiasts. Studies and reconstruction efforts continue to help people understand the appearance and historical significance of this remarkable religious center.
Uchiyama Eikyūji was far more than a Buddhist temple. For centuries, it played an influential role in the religious, political, and artistic life of the Yamato region. Its destruction during the anti-Buddhist movement represented a significant loss of Japan’s cultural heritage.
Today, the remaining pond, monuments, and surviving architectural treasures serve as reminders of a once-magnificent institution. The story of Uchiyama Eikyūji is also an important example of how political and religious changes can transform Japan’s cultural landscape. Its history remains valuable for understanding medieval Japanese Buddhism, the traditional relationship between Buddhism and Shinto, and the dramatic religious reforms of the Meiji era.
