Ancient Izumo King Tombs Hill

The area around Arashima Station overlooking Lake Nakaumi has a concentration of tombs built between the Yayoi and Kofun periods. Ancient Izumo King Tombs Hill consists of four parks, including the burial mounds at Chusenji, Miyayama, and Shiotsuyama, as well as the main Tsukuriyama Burial Mound group, one of the largest in the nation. Tombs in the park are all open to public viewing. There are royal tombs from the Yayoi period at Chusenji Park and Miyayama Park and four mounds like a flat-topped burial mound and conjoined rectangular mounds at Tsukuriyama Park. Excavations here showed the tombs in eastern Izumo were four-cornered. Today the site is known as a local recreation spot.
