The Fukuichi Site (福市遺跡, Fukuichi iseki) is an archaeological site with the traces of a late-Yayoi period(3rd century) to mid-Kofun period (5th century) settlement located in the "Chojabaru Plateau" area of the city of Yonago, Tottori Prefecture, in the San'in region of Japan.

[1] It has been known for a long time that ancient ruins are distributed in the Fukuichi Hills (25 meters above sea level) located at the confluence of the Hino River and the Hoshoji River in the city of Yonago, but archaeological excavations only began in 1966 immediately prior to the construction of a housing complex.

Of academic importance was evidence on how the shape of pit dwellings evolved from a circular to square layout over time.

Due to a petition by local residents, on October 17, 1970, 39,414 square meters of the Yoshizuka and Hiyakeyama districts were designated as National Historic Site.

After excavation, the area was backfilled for preservation and opened to the public as a park with restorations of pit dwellings.
