Nagoya Castle was built from 1610 for the Owari branch of the Tokugawa family. It was one of the grandest castles in Japan. The main keep, topped with a pair of golden shachihoko, mythical fish, was destroyed in 1945 and rebuilt in concrete in 1959. The Hommaru Palace has been reconstructed with painted screens and fine woodwork.

Atsuta Shrine in Nagoya is one of the most important Shinto shrines in Japan. It is believed to house the sacred sword Kusanagi, one of the three imperial regalia of Japan. Founded around 1,900 years ago, it is set in a forest of ancient camphor trees. Its treasure hall displays swords and other offerings, and millions visit at New Year.

Hikone Castle stands on a hill beside Lake Biwa in Shiga. Its keep, completed in 1622, is one of only twelve original castle keeps in Japan and a National Treasure. It was the seat of the Ii clan. The Genkyū-en garden lies at the foot of the castle, and the castle grounds are lined with cherry trees.

Himeji Castle is the largest and most famous surviving original castle in Japan. Its present form was completed in 1609. It is called the White Heron Castle because of its brilliant white walls and roofs that look like a bird taking flight. Its complex system of gates and maze-like paths was designed for defence. It was one of Japan's first UNESCO World Heritage Sites.
