The Battle of Shiroyama (城山の戦い, Shiroyama no tatakai) took place on 24 September 1877, in Kagoshima, Japan. It was the final battle of the Satsuma Rebellion, where the heavily outnumbered samurai under Saigō Takamori made their last stand against Imperial Japanese Army troops under the command of General Yamagata Aritomo and Admiral Kawamura Sumiyoshi. The battle culminated in the annihilation of Saigō and his army, marking the end of the Satsuma Rebellion. The Imperial Army's victory consolidated their power, and the Satsuma Rebellion was the last instance of internal mutiny seen in the Empire of Japan.
