大友宗麟
After Ōuchi Yoshinaga, Otomo Sorin's younger brother, was forced to commit suicide by the advance of Mōri forces in 1557, Mōri Motonari captured Yoshinaga's Moji fortress in 1558. In response, Otomo Sorin recaptured the castle in September 1559, but the Mōri, led by Kobayakawa Takakage and Ura Munekatsu, quickly took the castle back. In 1561, forces under Ōtomo Sōrin attacked the Moji castle in alliance with the Portuguese, but the assault failed, and the castle finally remained in Mōri possession.
