was an old province of Japan that is now the western half of Kagoshima Prefecture on the island of Kyūshū. Its abbreviation is . History Satsuma's provincial capital was Satsumasendai. During the Sengoku period, Satsuma was a fief of the Shimazu daimyō, who ruled much of southern Kyūshū from their castle at Kagoshima city. They were the initial patrons of Satsuma ware, which was later widely exported to the West. In 1871, with the abolition of feudal domains and the establishment of prefectures after the Meiji Restoration, the provinces of Satsuma and Ōsumi were combined to eventually establish Kagoshima Prefecture. Satsuma was one of the main provinces that rose in opposition to the Tokugawa shogunate in the mid 19th century. Because of this, the oligarchy that came into power after the Meiji Restoration of 1868 had a strong representation from the Satsuma province, with leaders such as Ōkubo Toshimichi and Saigō Takamori taking up key government positions. Satsuma is well known for its production of sweet potatoes, known in Japan as 薩摩芋 (satsuma-imo or "Satsuma potato"). Satsuma mandarins (known as mikan in Japan) do not specifically originate from Satsuma but were imported into the West through this province in the Meiji era.
