b) Description and inventory The designated buildings at Himeji-jo maintain the historical composition of an early 17th century castle complex, and also are characterized by design of outstanding artistic value. The nominated property thus meets the Article 1 definition of "groups of buildings".

The nominated group consists of 82 buildings as listed in Appendix 6, Inventory of buildings and copies official designation notices.

Although most of the buildings date back to the time of Ikeda Terumasa, constructed between 1601 and 1609, the towers and plastered earthen walls of one section of the Nishi-no-maru compound (the west bailey) were changed by Honda Tadamasa in the first half of the seventeenth century, and the easternmost gate of one section of the Ni-no-maru compound (the second bailey) dates back to a time earlier than that of Ikeda, to 1599.

At the center is the Tenshu-gun (the complex consisting of the donjon, three keeps and connecting structures, hereinafter referred to as the "donjon complex"). Surrounding these tall tower structures with their multiple layers of projecting roofs are structures used as watchtowers (turrets), gate buildings and plastered earthen walls all positioned according to strategic defensive planning considerations. This beautiful castle composition can be seen from almost any point in the city.

The donjon complex which forms the nucleus of the castle is situated at the highest location toward the northeastern part of the inner walled zone. The Dai-Tenshu (donjon) has five projecting roofs on the exterior, but actually has six interior stories plus one basement story; this donjon, together with the Higashi-kotenshu (3-story keep, to the east), the Inui-kotenshu (3-story keep, to the northwest) and the Nishi-kotenshu (3-story keep, to the west) are located at the four corners of the inner enclosure; the donjon and keeps are connected by narrow corridor structures (Watariyagura) completing an enclosure containing a courtyard.

The main pathway to the donjon complex is form the southwest. The land is partitioned to enclose ramped passageway spaces which rise gradually toward the donjon complex. The circulation layout was designed according to defensive planning principles, with plastered earthen walls forming the boundaries of each section and with gates positioned at several points along these walled passages. One must pass through a number of such gates, each a well-defended position, in order to reach the donjon. The gates closest to the donjon, in particular, are very simple ones, designed to appear as if they were part of the walls; de-emphasized in this manner, these gates were intended to deceive the attacking enemy soldiers in case they were able to penetrate this far into the castle.

The connecting passages (corridor structures) which stand to the north of the donjon complex provide storage space for provisions and other supplies necessary when entrenched in the castle during times of battle or under extended siege.

The path on the eastern side of the donjon complex, built with defensive strategy in mind, was purposely designed to meander, and its incline was made steep to make it difficult for enemy soldiers to pass through. At the top of the path are a tower, a gate and a plastered earthen wall, arranged to make it possible to attack the approaching enemy from above.

Presently there is a vacant space in the eastern portion (Bizen-maru) or the Ni-no-maru compound (the second bailey), to the south of the donjon coplex. This was originally the site of one of the castle lord's residential compounds, but these buildings were lost by fire in 1882.

The Nishi-no-maru compound (the west bailey), the site that Honda Tadamasa remodeled, was one of the residential compounds. But only the turrets, the connecting passages (corridor structures) and the plastered earthen walls remain today. The site now contains a Japanese garden; the residential buildings in this area were removed in 1874 in order to build military facilities.

There are circular, triangular and square gunports in the plastered earthen walls and towers. This not only shows clearly the characteristic defensive features of castle architecture but also creates an unique design.

The group of buildings at Himeji-jo is said to have an unusually elegant appearance, primarily because of the way that the entire composition is unified by the white plastered earthen walls. For this reason it is also well known as the Shirasagi-jo (White Heron Castle).
