Satsuma domain

Satsuma Domain (薩摩藩, Satsuma-han^?), also known as Kagoshima Domain, was a Japanese domain of the Edo period. It is associated with the provinces of Satsuma, Osumi and Hyūga in modern-day Kagoshima Prefecture and Miyazaki Prefecture on the island of Kyūshū.

In the han system, Satsuma was a political and economic abstraction based on periodic cadastral surveys and projected agricultural yields. In other words, the domain was defined in terms of kokudaka, not land area. This was different from the feudalism of the West.

The domain was ruled from Kagoshima Castle in Kagoshima city. Its kokudaka was assessed at 770,000 koku, the second highest kokudaka after that of Kaga Domain.

The Shimazu family controlled Satsuma province for roughly four centuries prior to the beginning of the Edo period. Despite being chastised by Toyotomi Hideyoshi in his 1587 Kyūshū Campaign, and forced back to Satsuma, they remained one of the most powerful clans in the archipelago. During the decisive battle of Sekigahara in 1600, the Shimazu fought on the losing side. Satsuma was one of the most powerful feudal domains in Tokugawa Japan. It was controlled throughout the Edo period by the tozama daimyō of the Shimazu clan.
