Mioyama

Due to its peculiar name, the statelet is used as an example of a possible placename that supports the Peninsular Japonic theory and a possible presence in Korea from ancient Japan.

However, due to the statelet's territories overlapping with Gaya and Silla, it can be theorized that the people of Mioyama had a similar culture with the aforementioned kingdoms.

This in turn claims that the real name of Mioyama was in fact "Mioya" which shares heavy resemblance with other statelets that end with "ya (邪)" such as in Guya (Korean: 구야국; Hanja: 狗邪國; RR: Guya) and Anya (Korean: 안야국; Hanja: 安邪國; RR: Anya).

According to the theory, two of the statelets include a suffix *-mietoŋ ⟨彌凍⟩, which has been compared with Late Middle Korean mith and Proto-Japonic *mətə, both meaning 'base, bottom' and claimed by Samuel Martin to be cognate.
