The Omuro Kofun Burial Mounds at the Foot of Mount Akagi
Historic tombs revealing the power of an ancient ruling clan
The Jonan area, where Omuro Park is located, is known for its large number of archaeological sites. Among them are Mae-Futago Kofun, Naka-Futago Kofun, Ushiro-Futago Kofun, and Ko-Futago Kofun, collectively known as the Omuro Kofun Burial Mounds.
Built during the 6th century, these keyhole-shaped burial mounds are believed to have been constructed for powerful figures who ruled the southern foothills of Mount Akagi. Their scale and sophisticated construction provide an impression of the political and social power held by the region’s ancient elite.
The burial mounds are spread across an area approximately 500 meters from north to south and 1,000 meters from east to west, creating a remarkable historical landscape that evokes the world of ancient Japan.
Mae-Futago Kofun: An Entrance to the Underworld
Mae-Futago Kofun became widely known after its stone burial chamber was investigated in 1878. Entering the narrow, elongated stone chamber can feel like stepping into another world, offering a fascinating glimpse into ancient burial practices.
Archaeological excavations uncovered numerous burial goods, including pottery, ornaments, mirrors, and gold-plated horse equipment. Historical records indicate that approximately 6,000 people came to see the excavation at the time. The British diplomat Ernest Satow was also present during the investigation, reflecting the considerable attention the discovery received.
Naka-Futago Kofun: The Largest of the Group
Naka-Futago Kofun is the largest of the Omuro burial mounds and retains an imposing appearance. Its structure originally featured a complete inner moat, central bank, and outer moat, while the burial mound itself was covered with stone.
Sections that had disappeared over time have been reconstructed to help visitors understand the mound’s original appearance. On the restored central bank, rows of shield-bearing haniwa figures and cylindrical haniwa have been placed, recreating the impression of ancient guardians surrounding the tomb.
The restoration allows visitors to observe the scale and structure of a large kofun at close range.
Ushiro-Futago Kofun: Sophisticated Stonework
Ushiro-Futago Kofun is another burial mound whose stone chamber was opened during the Meiji period. Archaeological research has revealed ingenious construction techniques, including building the stone chamber lower into the ground to reduce the amount of earth required to form the mound.
In the area in front of the burial chamber, evidence of cooking and ritual activities has been reconstructed and displayed, along with pottery. These exhibits provide clues about the ceremonies and religious practices associated with ancient burial traditions.
Ko-Futago Kofun: A “Department Store of Haniwa”
Ko-Futago Kofun is a relatively small keyhole-shaped burial mound measuring approximately 38 meters in length. It has a two-tiered structure and was built facing in the same direction as Ushiro-Futago Kofun.
Because of this relationship, it is thought to have been the burial place of a person closely connected with the individual buried in Ushiro-Futago Kofun.
A wide variety of haniwa figures were discovered here, earning the mound the nickname “the department store of haniwa.” The site illustrates the diversity and richness of kofun-period culture.
Omuro Haniwa Museum and Traditional Houses
Omuro Haniwa Museum
In the traditional house area in the western part of the park is a small museum called the Omuro Haniwa Museum. The facility occupies a renovated traditional storehouse and introduces the Omuro Kofun Burial Mounds through 3D video presentations.
Visitors can also see haniwa figures and pottery created by local volunteers, providing an approachable introduction to the culture of the kofun period.
The museum also offers opportunities to experience ancient-style clothing, making the history of the area especially engaging for families and younger visitors.
Traditional Houses and the Former Sekine Residence
The park contains a relocated and reconstructed Former Sekine Residence, an example of an Akagi-style farmhouse dating from the late Edo period. The building is designated as a Maebashi City Important Cultural Property.
The house provides a glimpse into the life of a traditional sericulture farming family. Visitors can view the interior and learn about everyday life in rural Japan. Reconstructed examples of ancient dwellings are also displayed, allowing visitors to explore changes in Japanese living culture across different historical periods.
Themed Areas Blending History with Nature
Omuro Park is not only a destination for history enthusiasts. The park also features a variety of landscaped areas designed to complement its natural surroundings.
These include the Hill of Passing Winds, Plaza of Time, Stone Chamber Zone, and Waterfront Zone, each offering a different atmosphere and experience.
The Hill of Passing Winds
The Hill of Passing Winds features stone wind chimes. The gentle sounds created by the wind provide a peaceful sensory experience and encourage visitors to slow down and enjoy the surroundings.
Plaza of Time
The Plaza of Time contains a water clock installation and cascading water feature. The flowing water creates a constantly changing scene and serves as a symbolic reminder of the passage of time.
Stone Chamber Zone
In the Stone Chamber Zone, visitors can hear the delicate sounds of a suikinkutsu, a traditional Japanese underground water harp. Its quiet tones add a contemplative atmosphere to the area.
Waterfront Zone and Goryo Pond
At Goryo Pond and the Waterfront Zone, visitors can observe and interact with aquatic life. These areas are particularly popular with families looking for a relaxing outdoor experience.
The park also protects a large konara Japanese oak designated as a Maebashi City Natural Monument, reflecting the importance placed on preserving the area’s natural environment.
Beauty in Every Season
Omuro Park offers different scenery throughout the year. Fresh green foliage brightens the park in spring, while summer brings clear blue skies and lush vegetation. In autumn, colorful foliage and expansive cosmos flower fields create an especially attractive landscape.
Winter brings crisp, clear air and excellent views of Mount Akagi. The combination of historical sites and seasonal scenery makes it possible to enjoy a different experience each time you visit.
The opportunity to explore ancient burial mounds while surrounded by flowers, trees, and open landscapes is one of the park’s most distinctive features.
Development and Archaeological Research
Plans to preserve and develop the historic sites began in the 1980s, followed by the establishment of a development committee in 1989. Archaeological excavations were conducted for six years beginning in 1991.
The park was subsequently developed based on the findings of these investigations. The archaeological research carried out at the Omuro Kofun Burial Mounds has contributed to a deeper understanding of the region’s ancient history and burial culture.
