Nagoya

Sitting near the center of the city, this castle is famous for its 'shachihoko,' the golden orcas that adorn the roof of its castle tower. The inside of Nagoya castle has been opened up as exhibition rooms, and you can see close-up items that tell the history of the city. The surrounding Meijo-koen park serves as home to many of Nagoya's best events, including the Sakura-matsuri (cherry blossom festival) in spring, the summer festival at Nagoya Castle, and the chrysanthemum doll show.
