Matsumoto Castle, Nagano Prefecture, Japan

Matsumoto Castle (松本城 Matsumoto-jo) is one of Japan's premier historic castles.
The building is also known as the "Crow Castle" (烏城 Karasu-jo) due to its black exterior.

It was the seat of the Matsumoto domain. It is located in the city of Matsumoto, in Nagano Prefecture and is within easy reach of Tokyo by road or rail.

The keep (tenshukaku), which was completed in the late sixteenth century, maintains its original wooden interiors and external stonework. It is listed as a National Treasure of Japan.

Matsumoto Castle is a flatland castle (hirajiro) because it is not built on a hilltop or amid rivers, but on a plain.
Its complete defences would have included an extensive system of inter-connecting walls, moats, and gatehouses.
