Komine-jo Castle is located in Shirakawa City, Fukushima Prefecture. Its walls are constructed entirely of stone, and it is counted as one of Tohoku's Three Famous Castles along with Morioka-jo Castle and Wakamatsu-jo Castle. The castle fell in the battle of Shirakawaguchi during the Boshin War, but using drawings from the Edo period as a reference, the three-story keep tower was rebuilt in 1991 and the front gate reconstructed in 1994. The three-story keep tower is one of only a few castle towers reconstructed in wood, and it can be seen clearly from the JR Shirakawa Station platforms. In recognition of its historical importance, the castle was declared a National Historic Site in 2010.
