What is Kokubunji

What is Kokubunji? A thorough explanation of its history, ruins, and modern-day Kokubunji City

Overview of Kokubunji

Kokubunji (国文寺) were government-sponsored temples established in 741 (Tenpyo 13) by Emperor Shomu, with the aim of protecting the nation through Buddhism. Their official name was “Konkomyo Shitenno Gokoku no Tera,” and two types were established: Kokubun-soji (国文寺) for male monks and Kokubun-niji (国文寺) for female nuns (officially known as Hokke Metsuzai no Tera).

During the mid-Nara period, Japan was plagued by epidemics, political turmoil, and natural disasters. Emperor Shomu, hoping to protect the nation from these calamities and bring peace and prosperity through the power of Buddhism, embarked on the grand project of constructing temples nationwide.

The Kokubunji system played a crucial role in strengthening the Ritsuryo system as a centralized state and supporting local governance from a religious perspective. Built near the provincial capitals of each province, these temples not only functioned as centers of regional Buddhist culture but also held important positions as places for supervision and education of monks and nuns within the province.

Historical Background of Kokubunji Construction

In the first half of the 8th century, while Japan was developing as a Ritsuryo state, it faced various difficulties. Epidemics such as smallpox swept through the country, claiming many lives. Politically, power struggles between the Fujiwara clan and other powerful families intensified, leading to increased social unrest. Furthermore, natural disasters such as earthquakes and droughts occurred frequently, severely impoverishing the lives of the people.

Emperor Shomu was a devout Buddhist and believed that the power of Buddhism could quell these calamities and bring peace to the nation. The imperial edict for the construction of Kokubunji in 741 was issued against this historical backdrop.

Imperial Edict for the Construction of Kokubunji Temples

On March 24, 741 (Tenpyo 13), Emperor Shomu issued the “Imperial Edict for the Construction of Kokubunji Temples.” This edict mandated the construction of Kokubun-ji temples (both monastic and nunnery) with seven-story pagodas in each province, the placement of 20 monks in the monastic temples and 10 nuns in the nunneries, and the copying of the *Golden Light Sutra* and the *Lotus Sutra*.

This edict was not merely a religious policy, but a crucial measure concerning the very foundation of national governance. It is believed to have aimed to connect the local and central governments through Buddhism and foster a unified national consciousness.

Layout and Architectural Style of Kokubunji Temples

The layout of Kokubunji temples generally consisted of the South Gate, Middle Gate, Main Hall, and Lecture Hall aligned in a straight line from north to south, with a cloister surrounding the Middle Gate and Main Hall. The seven-story pagoda was typically located to the east or west of the Main Hall. While the size of the buildings varied from province to province, certain standards were established. The main hall (Kondo) housed the principal image, Yakushi Nyorai (Medicine Buddha), while the lecture hall (Kodo) was used for Buddhist scripture lectures and monastic training. The seven-story pagoda (Nagoya) was a symbolic structure housing Buddhist relics, boasting a height visible from afar.

Selection Criteria for Kokubunji Temple Sites

The construction sites for Kokubunji temples were carefully selected in each province. The main selection criteria included the following points:

Location in Relation to the Provincial Capital

Kokubunji temples were generally built near the provincial capital. The provincial capital was the administrative center of each province, where the provincial governor conducted government affairs. By locating the Kokubunji temple near the capital, a system of governance integrating administration and religion could be established.

In many cases, locations within a few kilometers of the capital were chosen, ensuring easy access for the provincial governor. This ensured convenience for conducting national ceremonies and religious services.

Topography and Water Resources

Temple construction required vast, flat areas. Furthermore, a good water source was essential for the monks’ lives and agricultural production. Many Kokubunji temples were built near rivers or in areas with abundant springs.

In the case of Musashi Kokubunji, a relatively flat area on the Musashino Plateau was chosen, with springs and streams flowing nearby. These location conditions played a crucial role in the maintenance and establishment of the temple’s economic base.

Transportation Accessibility

Kokubunji temples served as centers of regional Buddhist culture, attracting many visitors. Therefore, locations with good access from major roads tended to be chosen.

Building along ancient official roads (ekiro) or near major local roads facilitated the movement of monks and the transportation of goods.

List and Characteristics of Major Kokubunji Temples

Musashi Kokubunji (Kokubunji City, Tokyo)

Musashi Kokubunji is a Kokubunji temple built in what is now Kokubunji City, Tokyo. Located on the Musashino Plateau, it boasted a vast temple grounds. Archaeological excavations have confirmed the remains of the main hall, lecture hall, and seven-story pagoda, and it is now designated a national historic site as the Musashi Kokubunji Temple Site.

The base of the seven-story pagoda was massive, measuring approximately 18 meters on each side, and the pagoda is estimated to have been over 60 meters tall. This was one of the largest seven-story pagodas in eastern Japan.

The current Musashi Kokubunji Temple was rebuilt after the Heian period and houses a wooden seated statue of Yakushi Nyorai (Medicine Buddha), a nationally designated Important Cultural Property, as its principal image. This statue is believed to be from the late Heian period and is a valuable cultural asset with a history of over 1200 years.

Yamato Kokubunji Temple (Nara City, Nara Prefecture)

Yamato Province was the location of the capital, and the Yamato Kokubunji Temple held a special position. While some theories suggest that Todaiji Temple effectively fulfilled the role of the Yamato Kokubunji Temple, others suggest the existence of a separate Kokubunji Temple, and research continues.

Sanuki Kokubunji Temple (Takamatsu City, Kagawa Prefecture)

Sanuki Kokubunji Temple is the 80th temple on the Shikoku 88 Temple Pilgrimage and continues to attract worshippers. The foundation stones of the original seven-story pagoda remain, conveying 1300 years of history.

The main hall was rebuilt during the Edo period, and the temple grounds feature a coexistence of ancient remains and buildings from the medieval period onward, creating a space that reflects the layering of history.

Ueno Kokubunji Temple (Takasaki City, Gunma Prefecture)

The ruins of Ueno Kokubunji Temple are located in Takasaki City, Gunma Prefecture, and archaeological excavations have revealed the layout of the temple complex. The foundations of the main hall and seven-story pagoda, as well as the remains of the earthen wall, have been confirmed, allowing us to imagine the magnificent temple of its time.

Role and Function of Kokubunji Temples

Religious Function

The primary role of Kokubunji temples was the protection of the nation through Buddhist rituals. The *Konkomyo Saisho-o Sutra* was regularly recited, and prayers were offered for national peace and abundant harvests.

Every year at the start of the new year, a Buddhist service called Kokki was held to pray for the safety and well-being of the emperor and the nation. Furthermore, special prayers were sometimes offered during epidemics and disasters.

Function as an Educational Institution

Kokubunji temples also played an important role as educational institutions for monks. Lectures on Buddhist scriptures were held in the lecture halls, where young monks learned Buddhist doctrines and rituals.

Copying scriptures was also an important part of training, and many scriptures were copied at Kokubunji temples. These copying activities contributed not only to the spread of Buddhist culture but also to the development of written culture.

Relationship with Local Communities

Kokubunji temples were also important in their local communities. They provided opportunities for the people to encounter Buddhism and served as a spiritual anchor.

In addition, Kokubunji temples possessed a certain amount of temple land and engaged in agricultural production. This is thought to have contributed to economic independence and the improvement of local agricultural technology.

Decline and Transformation of Kokubunji Temples

Changes After the Heian Period

With the arrival of the Heian period, national support for Kokubunji temples decreased along with the weakening of the Ritsuryo system. Many Kokubunji temples lost their economic base and were forced to downsize.

Some Kokubunji survived with the support of local influential figures, but maintaining the magnificent temple complexes of their founding days became difficult.

Revival and Decline in the Medieval Period

From the Kamakura period to the Muromachi period, some Kokubunji temples were revived as influential local temples. In particular, Kokubunji temples incorporated into the Shikoku 88 Temple Pilgrimage were revitalized by pilgrims visiting them.

However, many Kokubunji temples suffered damage from fire and destruction during the Sengoku period. Musashi Kokubunji was also destroyed by war and rebuilt on a smaller scale during the Edo period.

Preservation and Research in the Modern Era

From the Meiji era onward, Kokubunji temple sites came to be recognized as historical relics. From the Taisho to the Showa era, archaeological excavations were conducted at Kokubunji temple sites throughout the country, scientifically revealing the true nature of these ancient temples.

Currently, many Kokubunji temple ruins are designated as national and local government historical sites, and efforts are being made to preserve and utilize them. They are being developed as historical parks, and museums have been constructed, serving as places for historical education.
