Matsumoto Castle, also known as 'Crow Castle' due to its distinctive black exterior, is one of Japan's premier historic castles, located in the city of Matsumoto in Nagano Prefecture. The castle's origins date back to the 16th century, showcasing traditional Japanese feudal architecture. It is renowned for its wooden interiors and its strategic defensive design, including a secondary donjon and a 'moon viewing' turret. The main keep has been preserved beautifully, offering a glimpse into Japan's Warring States period. Inside the castle, visitors can explore the various levels, each with exhibits of armor, weapons, and information on the castle's history. The steep wooden stairs and low ceilings contribute to the authentic experience of samurai fortifications. The castle is surrounded by a serene moat and a park that changes with the seasons, offering cherry blossoms in spring and rich colors in autumn. Designated as a National Treasure of Japan, Matsumoto Castle is an iconic example of a Hirajiro, a castle built on plains rather than on a hill or mountain.
