Ijūin

The Ijūin were a branch of the Shimazu established at Ijūin in Satsuma Province. During the wars of the Northern and Southern Courts, Ijūin Tadakuni joined the Southern Court and fought the main Shimazu family, though later generations served it.

Ijūin Tadamune became a senior Shimazu retainer and received lands at Miyakonojō in Hyūga. After Shimazu Tadatsune killed him, his son Tadamasa rebelled in 1599; Tokugawa Ieyasu mediated a settlement, but Tadamasa was later killed.
