Ōsumi

Ōsumi district occupies the southern part of the peninsula of the same name, looking across Kagoshima Bay toward Satsuma. Its coast extends to Cape Sata, while the Ō River descends through the hills to Nejime. From the Heian period the area formed part of the Nejime estate; later it came under the direct authority of the Shimazu. Nejime and Sata were among the local districts through which their domain governed the peninsula.
