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.
In Katsuhisa's attempt to increase the prestige of the Iriki-In clan, he awarded Shigetomo with the Momotosugi Castle.
During the following year, Shigetomo overcame many forts such as the Hirasa, Kuma no sho, Miyasato, Tazaki, and Takea, also gaining prominence within Satsuma for his clan.
During the year to follow however, Shigetomo and Shimazu Takahisa's relationship between each other began to sour.
