Himeji Castle, also known as White Heron Castle due to its elegant, white appearance, is widely considered Japan's most spectacular castle for its imposing size and beauty and its well preserved, complex castle grounds. It was constructed in the mid-14th century, and a three-layer castle tower was built by Toyotomi Hideyoshi in the 16th century. The castle is both a national treasure and a world heritage site. Unlike many other Japanese castles, it was never destroyed by war, earthquake or fire and survives to this day as one of the country's twelve original castles. The castle hosts the Himeji Castle Cherry Blossom Viewing Fair, cherry blossom viewing drum music performance and Princess Sen-hime Peony Festival in spring, Himeji Castle Festival in summer, Moon Viewing Fair and Himeji Ceramics Market in autumn. Visitors can enjoy the city throughout the year.
