Shimada Ichirō (島田 一郎, 1848 – July 27, 1878) was a Japanese samurai who lived during the transition from the Edo period to the Meiji era.
Shimada Ichirō was born to an ashigaru in the Kaga Domain (modern city of Kanazawa), which was later merged to the Ishikawa Prefecture by the Meiji government.
Following the death of Saigō Takamori during the Satsuma Rebellion, a group of samurai among his sympathizers formed an antigovernment faction called Sankō-ji, led by Shimada.
[1] Shimada along with Chō Tsurahide disappeared from Kanazawa in March 1878, keeping the central government on high alert.
