The Satsuma Domain was ruled for its existence by the Tozama daimyō of the Shimazu clan, who had ruled the Kagoshima area since the 1200s, and covered territory in the provinces of Satsuma, Ōsumi and Hyūga. The Satsuma Domain was assessed under the Kokudaka system and its value peaked at 770,000 koku, the second-highest domain in Japan after the Kaga Domain.
