Matsumoto Castle

Matsumoto Castle, nicknamed Karasu-jo or Crow Castle for its black-lacquered wooden walls, is the oldest surviving original castle keep in Japan and one of only twelve castles never rebuilt after their original Edo-period or earlier construction. The five-story, six-floor keep rises directly from a wide moat stocked with koi and swans, its steeply pitched roofs and white-and-black facade forming one of the most photographed silhouettes in the Japanese Alps. Inside, visitors climb a series of original wooden staircases so steep they function almost as ladders, some at nearly 60-degree angles, passing displays of samurai armor, matchlock guns, and defensive features such as stone-dropping openings and gun ports built into the walls. The top floor is the highlight: a low-ceilinged lookout room with windows on all sides framing the Northern Alps' snow-capped peaks against the castle town below. A full visit, including the climb and grounds, takes 1.5 to 2.5 hours; the stairs create a slow-moving queue inside, so allow extra time during busy periods. The castle is at its most crowded on weekends, national holidays, and during the cherry blossom season in early April, when the moat's sakura trees frame the keep in pink. Photographers favor the Inner Moat Bridge for a straight-on view of the keep reflected in the water, and the northeast corner of the castle park for a composition that includes the Alps in the background. Weekday mornings right after opening, or the last hour before closing, offer the clearest photographs and shortest stair queues.
