The Siege of Moji (門司城の戦い, Moji-jō no tatakai) was a siege in 1561 against the castle of Moji in Japan. The castle belonged to the Mōri clan, whose capital was the city of Yamaguchi.
The original castle was built by Ouchi Yoshinaga, who was forced to commit suicide in 1557 with the advance of Mori forces. Mori Motonari captured the fort in 1558. Otomo Yoshishige recaptured the castle in Sept. 1559. The Mori, led by Kobayakawa Takakage and Ura Munekatsu, quickly recaptured the castle.
Forces under Ōtomo Sōrin attacked the castle in alliance with the Portuguese, who provided three ships between 500 and 600 tons, each with a crew of about 300 and 17 or 18 cannons. This is thought to be the first bombardment by foreign ships on Japan.
The bombardment permitted the Ōtomo troops to establish themselves around Moji castle. After expending their ammunition though, the Portuguese were forced to withdraw, unable to assist the siege further.
The castle's defenders nevertheless managed to break the siege lines and reinforce the castle. Ōtomo led an all-out assault on the castle on 10 Oct. 1561, but the assault failed, and the castle finally remained in Mōri possession.
