Himeji Castle is a World Cultural Heritage Site found in Himeji City in western Hyogo, Japan. It was constructed in the mid-14th century, and a three-layer castle tower was built by Toyotomi Hideyoshi in the 16th century. Ikeda Terumasa, a feudal Lord of the castle remodelled it in the 17th century. Its figure was likened to a white heron spreading wings, and thus also called Shirasagijo (White Heron Castle). It was designated as a national treasure in 1931, and the World Cultural Heritage in 1993.
