Chugoku Castles

中国

Chugoku mixes inland sea routes, coastal defenses, and powerful regional domains, producing a distinctive castle landscape. Matsue Castle in Shimane is one of Japan's five National Treasure keeps and remains in remarkable original condition, its dark wooden exterior earning it the nickname "the Black Castle." Hiroshima Castle, destroyed in 1945 and later reconstructed, stands as a symbol of the city's layered history. Bitchu-Matsuyama in Okayama is the only surviving original keep built at true mountain elevation, a steep climb rewarded with extraordinary views.
