The Mozu Kofun Group, located in Sakai City, Osaka Prefecture, is a massive collection of ancient burial mounds constructed during the 5th century. This area is characterized by a diverse range of tomb shapes, including keyhole-shaped mounds (zenpokoen-fun), scallop-shaped mounds, circular mounds, and square mounds. Most notably, the Daisenryo Kofun (traditionally believed to be the tomb of Emperor Nintoku) is a monumental structure with a length exceeding 200 meters, serving as a profound symbol of the scale and technological sophistication of ancient Japanese royal authority. In 2019, it was officially designated as a UNESCO World Heritage site alongside the Furuichi Kofun Group.
These tombs were primarily constructed between the 5th and 6th centuries. A distinctive feature of these sites is the presence of 'moats' (water-filled ditches) surrounding the mounds, a structure rarely seen in other parts of East Asia. The existence of these moats suggests a complex relationship with water, potentially reflecting the spread of wet-rice cultivation, the use of water for irrigation, or simply serving as a symbolic display of power. The keyhole shape itself is a significant piece of evidence used by researchers to study the political structures and cultural cycles of the era. While over 100 mounds once existed in this region, urban development has left 44 surviving structures today.
The defining characteristic of the Mozu Kofun Group is its sheer scale and variety of shapes. Key elements include:
As the Mozu Kofun Group consists of outdoor archaeological sites spread across the landscape, there are no specific seasonal restrictions for viewing. However, since the sites are observed from the outside, visiting during bright daylight hours is highly recommended. A clear, sunny day is best for grasping the topography and the impressive scale of the mounds and their surrounding terrain.
This site is a destination for observing historical remains from the exterior. Please note that entering the interior of the burial mounds is strictly prohibited. Visitors can observe the surrounding landscape and the intricate structure of the moats that encircle the mounds. It is an excellent site for understanding the spatial arrangement of historical relics and the cultural heritage of Sakai City.
The Mozu Kofun Group is situated in the northwestern part of Sakai City. The surrounding area includes other historical sites such as the Furuichi Kofun Group (located toward Higashi-Osaka and Izumi). The distribution of the tombs follows the natural plateau-like topography of the region.
The tombs are widely distributed and are primarily observed from public roads or sidewalks. Therefore, comfortable walking shoes are essential.
