Yomi referred simply to the location of Ne no kuni, and as such the theory that it was located somewhere between the town of Yomi in the city of Yonago, Tottori Prefecture, and the town of Higashi Izumo (where Yomotsuhirasaka was located) in Yatsuka county of Shimane Prefecture is most plausible; excavations nearby have unearthed huge square tombs built in a very early period of Japanese history (for example, Tsukuriyama tomb in the city of Yasugi in Tottori) as well as sokantotachi (swords) including an iron sword that closely resembles Kusanagi, one of the three Imperial Regalia.
黄泉とは単純に根の国の地名を指し、鳥取県米子市夜見町から黄泉平坂のある島根県八束郡東出雲町の間にあった土地と言う説が有力であり、それをうらづけるような早期ながら規模の大きな方形の古墳群が近隣に存在し（安来市造山古墳(島根県)）、素環頭大刀などのような天叢雲剣を髣髴させる鉄刀なども出土している。
