Iwakurazuka burial mound|Ancient burial mound with a horizontal stone chamber

Iwakurazuka burial mound is one of the Onohara tumulus group and is a burial mound with a horizontal stone chamber located in the precincts of Jiunji Temple. It is located in close proximity to the Bowlatsuzuka burial mound.
The stones used in the stone chamber are not large stones like those used in Wankashizuka, but small stones. As a result of previous research, it is thought that there may have been two stone chambers, one on the east and one on the west, with only the west chamber still in existence. Of the west stone chamber, the existing chamber is more than 4.5 m long, 2.9 m wide, and 2.9 m high, indicating that it was a large stone chamber. Iwakurazuka tumulus was additionally designated as a National Historic Site on March 10, 2020.
