Himeji Castle

Today we went to Himeji Castle. So far this has been the most impressive building we've been in.
[from wikipedia]
Himeji Castle was originally built in 1346. At this time, it was called Himeyama Castle. In 1331, Akamatsu Sadanori planned a castle at the base of Mount Himeji, where Akamatsu Norimura had constructed the temple of Shomyoji. After Akamatsu fell during the Kakitsu War, Yamana clan briefly took over planning of the castle; the Akamatsu family took over again following the Ōnin War.

In 1580, Toyotomi Hideyoshi took control of the badly damaged castle, and Kuroda Yoshitaka built a three-story tower. Following the Battle of Sekigahara in 1600, Tokugawa Ieyasu granted Himeji Castle to Ikeda Terumasa who embarked on a nine-year expansion project that brought the castle roughly to its current form. "Only the east gate of one section of the second bailey" survived from the earlier period.[1] The current keep dates from 1601, and the last major addition, the Western Circle, was completed in 1618.
