Matsumoto is one of Japan’s principal historic castles; indeed, it is considered a National Treasure of Japan. Because of its black exterior, the castle is commonly known as the ‘Crow Castle.’ Matsumoto Castle resides in Nagano Prefecture, an easy train ride from Tokyo proper, and is a hirajiro, or flatland castle, which distinguishes it from many others that were strategically constructed on hills or surrounded by rivers. Built in the late 16th century, the fortress consisted of a series of moats, a complex system of walls, and gatehouses. The castle was created during the Sengoku period, a time of considerable social upheaval in Japan. In the late 1800s, it was sold at auction for the purpose of redevelopment. A local high school principal spearheaded the renovation efforts and raised funds to carry them out.
