Kuronuki-dera Temple, located in Iwazume, Saito City, Miyazaki Prefecture, is a historical temple deeply connected to Japanese mythology. Built on the site of “Takaya Palace,” where Emperor Keiko is said to have stayed for six years during his campaign against the Kumaso people, it remains a Shingon sect Chizan-ha temple and continues to attract local devotion. This article comprehensively introduces information useful for your visit, from the history and highlights of Kuronuki-dera Temple to access methods.
History and Origin of Kuronuki-dera Temple
Legend of Emperor Keiko and Takaya Palace
The land where Kuronuki-dera Temple stands was an important stage in Emperor Keiko’s campaign against the Kumaso people, as recorded in the *Nihon Shoki* (Chronicles of Japan). Emperor Keiko traveled to Hyuga Province (present-day Miyazaki Prefecture) to pacify the Kumaso people of southern Kyushu and established a temporary palace called “Takaya Palace” in this location.
According to tradition, Emperor Keikō stayed in this area for six years, from 71 to 77 AD. The Emperor, along with Yamato Takeru no Mikoto, used this palace as a base for his campaign against the Kumaso people, laying the foundation for his rule over Kyushu. This Takaya Palace was built using the Kuroki-zukuri style (an architectural style using logs without stripping the bark), and it is said that this “Kuroki” (black wood) evolved into the place name “Kurokan.”
Founding and Development as a Temple
Kurokanji Temple, as a Buddhist temple, is said to have been founded in 946 AD by Abbot Ryūgen. It belonged to the Chizan branch of the Shingon sect and developed as a training ground for esoteric Buddhism.
Of particular note is the prosperity of Kurokanji Temple during the medieval period. During the time of the Itō clan, who ruled Hyūga Province from the Kamakura period to the Sengoku period, Kurokanji Temple flourished as “the foremost temple in Hyūga.” The Ito family protected this temple for generations, and it grew into a large temple complex with many buildings. Ikkai, a member of the Ito family, dedicated himself to developing the temple grounds and is known for constructing the “Shinji Pond” (described later).
Changes After the Sengoku Period
In 1577, when the Ito family was defeated in battle against the Shimazu family and driven out of Hyuga Province, Kurokanji Temple also lost its patronage and its former prosperity. However, the temple’s traditions have continued uninterrupted to the present day.
During the Edo period, it came under the control of the Satsuma Domain and survived as a local family temple. Although affected by the anti-Buddhist movement after the Meiji Restoration, it survived thanks to the faith of the local residents and continues to operate as a Shingon Buddhist temple today.
Highlights and Grounds Guide of Kurokanji Temple
Main Hall and Buddhist Statues
The main hall of Kurokanji Temple is a magnificent building with a solemn atmosphere befitting a Shingon Buddhist temple. The principal image is Fudo Myoo, a revered deity in Esoteric Buddhism. Several other Buddhist statues are also enshrined within the hall, making them valuable cultural artifacts that tell the story of its long history.
While the main hall’s architectural style dates from a modern reconstruction, the overall layout of the temple grounds retains strong traces of ancient tradition. Visitors can quietly offer their prayers in the main hall, feeling the spiritual energy of this place with over a thousand years of history.
Shinji-no-ike Pond
A particularly noteworthy feature within the grounds of Kurokanji Temple is the “Shinji-no-ike Pond.” As its name suggests, this garden pond is shaped like the Chinese character for “heart” (心), representing a traditional style of Japanese gardens.
It is said that the Shinji-no-ike Pond was constructed by Ikkai, a member of the Ito clan. Because the pond’s shape resembles the character for “heart,” it is believed to represent the importance of “heart” in Buddhism, specifically the state of Zen meditation and contemplation.
Stone arrangements surround the pond, allowing visitors to enjoy the changing seasons. Especially during the fresh greenery of spring and the vibrant autumn foliage, the reflections of the trees on the water’s surface are beautiful, soothing the hearts of visitors. This pond can be considered a valuable historical site that conveys the high level of cultural sophistication during the heyday of the Ito clan.
Relationship with Takaya Shrine
Across from Kurokanji Temple lies Takaya Shrine. This shrine is dedicated to Emperor Keiko and, together with Kurokanji Temple, is an important historical site that constitutes the Takaya Palace ruins.
Before the Meiji-era separation of Shinto and Buddhism, Kurokanji Temple and Takaya Shrine functioned as a single religious complex. During the era of syncretism of Shinto and Buddhism, it was not uncommon for temples and shrines to coexist within the same grounds, and it is believed that Kurokanji Temple also played a role as a betto-ji (a temple that managed the shrine).
Even today, the two are adjacent, and visitors can experience the layered history of this area by visiting both the temple and the shrine. From the grounds of Takaya Shrine, you can enjoy a panoramic view of Saito City, a view that makes you understand why Emperor Keiko chose this location.
Natural Environment of the Temple Grounds
The grounds of Kurokanji Temple are surrounded by abundant nature. Ancient trees flourish, creating a tranquil atmosphere where you can find peace of mind. Each season has its own charm, especially in spring when the cherry blossoms bloom, in summer when it is enveloped in deep green, in autumn when the leaves change color beautifully, and in winter when a crisp air permeates the air.
A stroll through the grounds will help you understand why this place has been cherished as a sacred site since ancient times. The quiet environment is suitable for meditation and introspection, making it an ideal place to escape the hustle and bustle of modern life and find inner peace.
Historical Background of the Area Around Kurokanji Temple
Saito City and Ancient Hyuga Province
Saito City, where Kurokanji Temple is located, was one of the centers of the ancient Hyuga Province. Within the city is the Saitobaru Kofun Cluster, one of the largest groups of ancient burial mounds in Japan, indicating that this region was an important political and cultural center from ancient times.
Emperor Keikō likely chose the Saito region as his base for conquering the Kumaso people because it was a strategically important location for governing southern Kyushu. The site of Kurokanji Temple was located at a key point on ancient transportation routes and was militarily important.
The Ito Clan and the Medieval History of Hyūga Province
The prosperity of Kurokanji Temple is deeply intertwined with the Ito clan, who ruled Hyūga Province during the medieval period. The Ito clan entered Hyūga Province as jitō (land stewards) during the Kamakura period and grew into a powerful daimyo (feudal lord) controlling almost the entire province during the Sengoku period.
The Ito clan were devout Buddhists and protected temples within their territory. Kurokanji Temple, in particular, received special treatment, boasting a scale and prestige that earned it the title of “the foremost temple in Hyūga.” It was also close to Tonokori Castle, the Ito clan’s base, and is thought to have served as a family temple for the clan.
When the Ito clan was defeated by the Shimazu clan in the Battle of Kizakihara in 1577, the Ito clan fled to Bungo Province (present-day Oita Prefecture), and Kurokanji Temple also lost its protection. This historical turning point drastically altered the fate of Kurokanji Temple.
Kurokanji Site and Prehistory
Around Kurokanji Temple, there is also a Paleolithic site called the “Kuronaka Site.” Paleolithic stone tools have been unearthed from this site, revealing that humans have inhabited this area for tens of thousands of years.
The traces of human activity, continuing uninterrupted from ancient times to the present, speak to the deep history of the place name Kurokanji. This land has been a place of human life since a time far older than the reign of Emperor Keiko.
