Himeji castle is widely believed to be Japan’s most spectacular castle. It was never destroyed in wars, earthquakes, or fires, and survives in its original form. Begun in the 14th century, the current complex reflects the 1609 configuration. As a hilltop castle, the complex has a network of 83 buildings and a series of advanced defensive systems.
Although the castle keep appears to have five floors, it actually has six and a basement. Climbing to the top was very strenuous, especially given the heat and humidity on the day I visited.
