오카야마 성, also known as "Crow Castle" due to its black exterior, is a historic Japanese castle located in 오카야마 Prefecture. Built in the late 16th century by 우에스기 겐신, it served as a strategic military base and residence for feudal lords. The castle features a unique architectural style and is surrounded by a beautiful park. The castle was reconstructed after being destroyed during World War II and now serves as a museum. Visitors can explore its exhibits, which showcase the history of the castle and the region. The surrounding gardens, especially during cherry blossom season, attract many tourists each year.
