The Battle of Momotsugi was fought on October 9, 1539 when an army of the Iriki-in clan (loyal to Shimazu Takahisa) stormed the castle of Iwaya, aligned with the rival Shimazu Sanehisa.
Sanehisa had been the lord of Izumi castle in Satsuma province. He was a member of a branch family of the Shimazu. In 1526 he rebelled against Shimazu Katsuhisa and managed to expel him from Satsuma Province. Sanehisa attempted to establish himself as an independent power. With the clan's allegiance divided, Iriki-in Shigetomo remained loyal to Katsuhisa and his successor Takahisa.
Momotsugi Castle had been granted to the Iriki-in in 1536, motivating Shigetomo to capture it first since it was held by Sanehisa's forces. [1] Shigetomo took the castle on a single night raid. [2] The action earned Shigetomo's praise from his Lord Shimazu Takahisa.

Shimazu Tadayoshi was a daimyō of Satsuma Province during Japan's Sengoku period. He was born into the Mimasaka Shimazu family (伊作島津家), which was part of the Shimazu clan, but after his father Shimazu Yoshihisa died, his mother married Shimazu Unkyu of another branch family, the Soshū (相州家). Tadayoshi thus came to represent two families within the larger Shimazu clan.
Iriki-In Shigetomo, the son of Iriki-In Shigetoshi, was a vassal under the Shimazu clan of Satsuma. The lord of the Shimazu clan, Shimazu Katsuhisa, suffered the rebellion of a kinsman, Sanehisa, and was forced to flee Satsuma during 1526. The Shimazu clan head was then passed on to Katsuhisa's eldest son, Shimazu Takahisa. Even though Takahisa was the new head, Katsuhisa still had authority over a good amount of land. Considering Shigetomo's lands were very close to that of the Shimazu's, he found himself in conflicts between the Sanehisa around Momotosugi.
