| Description | A group of ancient tombs located along the Gonzugawa River, a tributary of the Naka River, which is believed to be the center of the region where the Nasu-no-kuni-no-miyatsuko was established. （About Kuni-no-miyatsuko A local official of the Yamato Imperial Court. The Imperial Court organized the powerful clans that had independent power in each region into a governing body. Abolished with the Taika Reform. Under the Ritsuryo system, one person was newly appointed per province, and was in charge of rituals and Shinto rituals. （Komagata-otsuka burial mound) Located at the eastern end of the uppermost surface of the river terrace of the Naka River, this is a 60.5 m long, 6.5 m high, east-west oriented, front-rear burial mound with its main axis in the east-west direction. Excavations were conducted in 1974, and abundant burial accessories were found about 1.5m below the mound. The main part of the burial chamber is located on the main axis of the mound, and it is estimated to be a charcoal burial chamber (wooden coffin covered with charcoal) with the length of 5.4m from east to west and 1.6m from north to south. A four-jeweled mirror with an imported design was found in the western part of the chamber, as well as copper arrowheads, straight swords, sword staves, an iron sword, a yariganna, an iron axe, and a glass bead. Since these burial accessories were covered with vermilion, it is thought that vermilion was applied to the wooden coffin after the body and the accessories were placed inside. No thatched stones can be seen on the mound. The front part of the burial mound is flattened, but the front end of the mound is slightly open. The burial mound is representative of the period when kofun tumuli appeared in eastern Japan (approximately 1,700 years ago), as the pottery used for burial as well as the burial accessories are clearly visible. (Yoshidayuzenjinja Tumulus Group and Nasu Hachimanzuka Tumulus Group) The tombs are concentrated on the eastern edge of the river terrace overlooking the confluence of the Naka and Gonzu Rivers below, forming the Yoshida-Arajuku tumulus cluster. The northern side is called the Yoshidayuzenjinja Tumulus Group and the southern side the Nasu Hachimanzuka Tumulus Group. The Yoshidayuzenjinja tumulus group includes the Yoshidayuzenjinja tumulus (forward-backward) and the Kannondo tumulus (square). The Nasu Hachimanzuka tumulus group includes the Nasu Hachimanzuka tumulus (anteroposterior) and the Yoshida-Fujiyama tumulus (square). Together, there are more than 20 Early Period burial mounds in a row, stretching 1 km from north to south. The Nasu Hachimanzuka burial mound was excavated in 1953 by the Ogawa Town Ancient Culture Study Group (now the Ogawa Town Association for the Protection of Cultural Properties) under the guidance of Fumio Miki, and was found to be a forward-rear mound with thatched stones. In addition, a direct burial facility with a wooden coffin with clay lumps placed at both ends was discovered 1 m below the apex of the rear part of the burial mound. The burial was presumed to have been made with the head facing east, and a rich assortment of burial accessories, including an imported mirror, a sword, a saw, a yariganna, an axe, and a sickle, were excavated. Furthermore, excavations conducted in 1991 in conjunction with the development of this burial mound revealed that the front part of the mound had a distinctive shape, with both corners cut off, and that the shape of the excavation around the perimeter was irregular. In addition, a jar with a rounded mouth, a vessel stand, a bowl, and a pot were excavated from the excavation, indicating that this burial mound was constructed in the early Kofun period (1,750 years ago) |
