It is a square shaped tomb in a lateral holed, stone room. It is estimated that the construction dates back to the beginning of the 7th century. The enclosure of the upper part has already been lost and the giant stone is exposed.
This tumulus seems to be the burial mound of Soga no Umako (550?-626), who was an Oomi, the highest officer in national politics during the Yamato dynasty. According to the excavation investigation, the household was 7.7m long, about 3.5m wide, 4.7m high. Large and small 30 granites were used. The weight of the stone used on the ceiling, the northern side, was about 64t, and the southern side was about 77t.
The gross weight was about 2,300t. 1300 years later, the stone works did not collapse even after the Hanshin Awaji Great Earthquake, with a seismic intensity of about 5. It shows the precise process of carefully preparing the surface of a large stone.

“You will find the ancient elephant in the Paleolithic Age” -Akashi is on a complex landscape of Hills and Plains. 2 million years ago, it was the floor of a lake. In those days, the ancient elephant, Akashizou (Stegodon Aurorae), and great deer, which were as large as cows, stayed lakeside. This museum shows the skeleton specimen of the ancient elephant excavated here.
At this museum, you can learn about the history and culture of Akashi from ancient times to the present, and it introduces the dawn of Akashi City. Although the fossilized human bones of Akashi-Genjin, the humans in Akashi were lost in the Tokyo air raid during World War II, a piece of wood, with traces of human modification, was found in the same stratum where Akashi-Genjin was found on the Akashi coast, from 120,000 to 50,000 years ago. As a result, it was almost certain that Akashi had humans during that time.

The southern Zenkojidaira, where the Chikuma River and the Sai River join, has been a source of rich soil and a large distribution center, since ancient times.

He built a keyhole tomb with a total length of about 100m on which stones were piled and lined with Haniwa (clay images).
