Himeji Castle
One of Japan's most renowned castles and a UNESCO World Heritage Site. Built by Ikeda Terumasa in the early Edo period, the main keep has five exterior tiers, six aboveground floors, and one basement level. It is the largest surviving castle keep from the Edo period. The castle was constructed using a comprehensive defensive layout known as sokamae, with the entire castle town enclosed within its moats. It was large enough to encompass what is now central Himeji, and the outer moat is said to have been located around present-day Himeji Station.
The gardens and natural scenery around Himeji Castle are also well worth a visit.
