Okayama is the capital city of its namesake prefecture, in western Japan. It’s known for the 16th-century Okayama Castle, dubbed “Crow Castle” for its black exterior, and for Korakuen, an iconic formal garden. The Hayashibara Museum of Art shows East Asian art and artifacts. The Okayama Prefectural Museum of Art displays regional works. To the west, 15th-century Kibitsu-jinja Shrine features a long, covered walkway.
