Kagoshima, Kagoshima in the context of "Kagoshima Castle"

Ōsumi Province (大隅国, Ōsumi no Kuni; Japanese pronunciation: [o(ꜜ)ː.sɯ.mʲi (no kɯ.ɲi)]) was a province of Japan in the area of southeastern Kyushu, corresponding to the eastern half of modern Kagoshima Prefecture, and including the Ōsumi Islands . Ōsumi bordered on Hyūga to the northeast, and Satsuma Province to the northwest. Its abbreviated form was Gūshū (隅州). In terms of the Gokishichidō system, Ōsumi was one of the provinces of the Saikaidō circuit. Under the Engishiki classification system, Ōsumi was ranked as one of the "middle countries" (中国) in terms of importance, and one of the "far countries" (遠国) in terms of distance from the capital.

The Ōsumi region has developed its own distinct local dialect. Although Ōsumi is part of Kagoshima Prefecture today, this dialect is different from that spoken in the city of Kagoshima. There is a notable cultural pride in traditional poetry written in Ōsumi and Kagoshima dialects.
