context_page_description: Himeji Castle is a hilltop Japanese castle complex situated in the city of Himeji which is located in the Hyōgo Prefecture of Japan. The castle is regarded as the finest surviving example of prototypical Japanese castle architecture, comprising a network of 83 rooms with advanced defensive systems from the feudal period. The castle is frequently known as Hakuro-jō or Shirasagi-jō because of its brilliant white exterior and supposed resemblance to a bird taking flight.
  Himeji Castle dates to 1333, when Akamatsu Norimura built a fort on top of Himeyama hill. The fort was dismantled and rebuilt as Himeyama Castle in 1346, and then remodeled into Himeji Castle two centuries later. Himeji Castle was then significantly remodeled in 1581 by Toyotomi Hideyoshi, who added a three-story castle keep. In 1600, Tokugawa Ieyasu awarded the castle to Ikeda Terumasa for his help in the Battle of Sekigahara, and Ikeda completely rebuilt the castle from 1601 to 1609, expanding it into a large castle complex. Several buildings were later added to the castle complex by Honda Tadamasa from 1617 to 1618.
context_section_description: Himeji Castle is the largest castle in Japan. It serves as an excellent example of prototypical Japanese castle architecture, containing many of the defensive and architectural features associated with Japanese castles. The curved walls of Himeji Castle are sometimes said to resemble giant fans (扇子, sensu), but the principal materials used in the structures are stone and wood. Feudal family crests (家紋, kamon) are installed throughout the architecture of the building, signifying the various lords that inhabited the castle throughout its history. 
  The specific style of the castle is a hirayama (平山城 flat hilltop). Two castles that were built during the same time and shared many of the architectural features are Matsuyama Castle (Iyo) and Tsuyama Castle.
  The Himeji Castle complex is located in the centre of Himeji, Hyōgo on top of a hill called Himeyama, which is 45.6 m (150 ft) above sea level. The castle complex comprises a network of 83 buildings such as storehouses, gates, corridors, and turrets (櫓, yagura). Of these 83 buildings, 74 are designated as Important Cultural Assets: 11 corridors, 16 turrets, 15 gates, and 32 earthen walls. The highest walls in the castle complex have a height of 26 m (85 ft). Joining the castle complex is Kōko-en (好古園), a Japanese garden created in 1992 to commemorate Himeji city's 100th anniversary.
  From east to west, the Himeji Castle complex has a length of 950 to 1,600 m (3,120 to 5,250 ft), and from north to south, it has a length of 900 to 1,700 m (3,000 to 5,600 ft). The castle complex has a circumference of 4,200 m (2.6 mi). It covers an area of 233 hectares (2,330,000 m² or 576 acres), making it roughly 50 times as large as the Tokyo Dome or 60 times as large as Koshien Stadium.
  The main keep (大天守, daitenshu) at the center of the complex is 46.4 m (152 ft) high, standing 92 m (302 ft) above sea level. Together with the main keep, three smaller subsidiary keeps (小天守, kotenshu) form a cluster of towers. Externally, the keep appears to have five floors, because the second and third floors from the top appear to be a single floor; however, it actually has six floors and a basement. The basement of the main keep has an area of 385 m² (4,140 sq ft), and its interior contains special facilities that are not seen in other castles, including lavatories, a drain board, and a kitchen corridor.
  The main keep has two pillars, with one standing in the east and one standing in the west. The east pillar, which has a base diameter of 97 cm (38 in), was originally a single fir tree, but it has since been mostly original. The base of the west pillar is 85 by 95 cm (33 by 37 in), and it is made of Japanese cypress. During the Shōwa Restoration (1956–1964) a Japanese cypress tree with a length of 26.4 m (87 ft) was brought down from the Kiso Mountains and replaced the old pillar. The tree was broken in this process, so another tree was brought down from Mount Kasagata, and the two trees were joined on the third floor.
  The first floor of the main keep has an area of 554 m² (5,960 sq ft) and is often called the "thousand-mat room" because it has over 330 Tatami mats. The walls of the first floor have weapon racks (武具掛け, bugukake) for holding matchlocks and spears, and at one point, the castle contained as many as 280 guns and 90 spears. The second floor has an area of roughly 550 m² (5,900 sq ft).
  The third floor has an area of 440 m² (4,700 sq ft) and the fourth floor has an area of 240 m² (2,600 sq ft). Both the third and fourth floors have platforms situated at the north and south windows called "stone-throwing platforms" (石打棚, ishiuchidana), where defenders could observe or throw objects at attackers. They also have small enclosed rooms called "warrior hiding places" (武者隠し, mushakakushi), where defenders could hide themselves and kill attackers by surprise as they entered the keep. The final floor, the sixth floor, has an area of only 115 m² (1,240 sq ft). The sixth floor windows now have iron bars in place, but in the feudal period the panoramic view from the windows was unobstructed.
