- Japanese castle
nihongo|Japanese castles|城|shiro were
fortresses composed primarily of wood and stone. They evolved from the wooden stockades of earlier centuries, and came into their most well-known form in the 16th century. Like European castles, the castles of Japan were built to guard important or strategic sites, such as ports, river crossings, or crossroads, and almost always incorporated the landscape into their defense.
Though they were built to last, and used more stone in their construction than most Japanese buildings, castles were still constructed primarily of
wood, and many were destroyed over the years. This was especially true during the Sengoku ('Warring States') period (1467-1603), when many of these castles were first built. However, many were rebuilt, either later in the Sengoku period, in the Edo period (1603-1867) which followed, or more recently, as national heritage sites or museums. Today, there are around fifty castles extant, or partially extant, in Japan; it is estimated that once there were five thousand.cite book|last=Inoue|first=Munekazu|year=1959|title=Castles of Japan|location=Tokyo|publisher=Association of Japanese Castle] Some castles, such as the ones at Matsue and Kōchi, both built in 1611, remain extant in their original forms, not having suffered any damage from siege or other threats. Hiroshima Castle, on the opposite end of the spectrum, was destroyed in the atomic bombing, and was rebuilt in 1958as a museum.cite book|title=DK Eyewitness Travel Guide: Japan|location=London|publisher=DK Publishing|year=2002]
The character '城', normally read as "shiro", is read as "jō" when it is attached to a word, such as in the name of a particular castle. Thus, for example,
Osaka Castleis called "Ōsaka-jō" (大阪城) in Japanese.
Originally conceived of purely as fortresses, their primary purpose being military defense, Japanese castles were originally placed in strategic locations, along trade routes, roads and rivers. Though castles continued to be built with these considerations in mind, for centuries fortresses were also built to serve as centers of governance. By the Sengoku period, they had come to serve as the homes of
daimyo(feudal lords), and served to impress and intimidate rivals not only with their defenses, but with their size and elegant interiors, architecture and decorations. Oda Nobunagawas one of the first to build one of these palace-like castles, at Azuchi Castlein 1576; this was Japan's first castle to have a tower keep (天守閣, "tenshukaku"), and it inspired both Toyotomi Hideyoshi's Osaka Castleand Tokugawa Ieyasu's Edo Castle.cite book|last=Treat|first=Robert|coauthors=Alexander Soper|year=1955|title=The Art and Architecture of Japan|location=New Haven|publisher=Yale University Press] Azuchi served as the governing center of Oda's territories, and as his lavish home, but it was also very keenly and strategically placed. A short distance away from the capital of Kyoto, which had long been a target of violence, Azuchi's carefully chosen location allowed it a great degree of control over the transportation and communication routes of Oda's enemies.
Prior to the
Sengoku period(roughly, the 16th century), most castles were called "yamashiro" (山城), or 'mountain castles'. Though most later castles were built atop mountains or hills, these were built "from" the mountains.cite book|last=Turnbull|first=Stephen|year=2003|title=Japanese Castles 1540-1640|location=Oxford|publisher=Osprey Publishing] Trees and other foliage were cleared, and the stone and dirt of the mountain itself was carved into rough fortifications. Ditches were dug, to present obstacles to attackers, as well as to allow boulders to be rolled down at attackers. Moats were created by diverting mountain streams. Buildings were made primarily of wattle and daub, using thatched roofs, or, occasionally, wooden shingles. Small ports in the walls or planks could be used to deploy bows or fire guns from. The main weakness of this style was its general instability. Thatch caught fire even more easily than wood, and weather and soil erosion prevented structures from being particularly large or heavy. Eventually, stone bases began to be used, encasing the hilltop in a layer of fine pebbles, and then a layer of larger rocks over that, with no mortar. This support allowed larger, heavier, and more permanent buildings.
The first fortifications in Japan were hardly what one generally associates with the term "castles." Made primarily of earthworks and wood, the earliest fortifications made far greater use of natural defenses and topography than anything manmade. These "kōgoishi" and "chiyashi" never intended as long-term defensive positions, let alone residences; the native peoples of the archipelago built fortifications when they were needed and abandoned the sites afterwards.
Yamato peoplebegan to build cities in earnest in the 7th century, complete with expansive palace complexes, surrounded on four sides with walls and impressive gates. Earthworks and wooden fortresses were also built throughout the countryside to defend the territory from the native Emishi, Ainu and other groups; unlike their primitive predecessors, these were relatively permanent structures, built in peacetime. These were largely built as extensions of natural features, and often consisted of little more than earthworks and wooden barricades.
Nara period(c. 710-794) fortress at Dazaifu, from which all of Kyūshūwould be governed and defended for centuries afterwards, was originally constructed in this manner, and remnants can still be seen today. A bulwark was constructed around the fortress to serve as a moat to aid in the defense of the structure; in accordance with military strategies and philosophies of the time, it would only be filled with water at times of conflict. This was called a "mizuki" (水城), or "water fort".cite book|last=Hirai|first=Kiyoshi|year=1973|title=Feudal Architecture of Japan|location=Tokyo|publisher= Heibonsha] The character for castle or fortress (城), up until sometime in the 9th century or later, was read (pronounced) "ki", as in this example, "mizuki".
Though fairly basic in construction and appearance, these wooden and earthwork structures were designed to impress just as much as to function effectively against attack. Chinese and Korean architecture strongly influenced the design of Japanese buildings, including fortifications, in this period. The remains or ruins of some of these fortresses, decidedly different from what would come later, can still be seen in certain parts of Kyūshū and
Heian period(794-1185) saw a shift from the need to defend the entire state from invaders to that of lords defending individual mansions or territories from one another. Though battles were still continually fought in the north-east portion of Honshū(the Tōhoku region) against native peoples, the rise of the samurai warrior class [The term "samurai", deriving from "saburai" (one who serves), refers both to the armed feudal retainers who fought for their lords in feudal Japan, but also to the noble warrior class as a whole. Thus, unlike the European knight, the samurai was a samurai by virtue of his birth, retaining this status regardless of his rank. The samurai bore close ties to his clan (the noble family of his lineage), and to other clans to which his own owed fealty, serving loyally in the defense of his lord's lands, in assaults upon enemy lands, or in a variety of other ways. For more on the role of the samurai class and its development over time, see Samurai.] towards the end of the period, and various disputes between noble families jostling for power and influence in the Imperial Court brought about further developments. The primary defensive concern in the archipelago was no longer native tribes or foreign invaders, but rather internal conflicts within Japan, between rival samuraiclans or other increasingly large and powerful factions, and as a result, defensive strategies and attitudes were forced to change and adapt. As factions emerged and loyalties shifted, clans and factions which had been allies in the service of the Imperial Court became enemies, and defensive networks were broken, or altered through the shifting of alliances.
Genpei War(1180-1185) between the Minamoto and Taira clans, and the Nanboku-chōWars (1336-1392) between the Northern and Southern Imperial Courts are the primary conflicts that define these developments during what it sometimes called Japan's medieval period.
Fortifications were still built almost entirely out of wood, and were based largely on earlier modes, and on Chinese and Korean examples. But they began to become larger, to incorporate more buildings, to accommodate larger armies, and to be conceived as more permanent structures. This mode of fortification, developed gradually from earlier modes and used throughout the wars of the
Heian period(770-1185), and deployed to help defend the shores of Kyūshū from the Mongol invasions of the 13th century, [The only invasion attempts upon Japan in the 2nd millennium, these had a not insignificant impact upon defenses in and around Hakata, where the Mongols landed, but are exceptions to the trend of internal warfare which guided military developments in pre-modern Japan.] reached its climax in the 1330s, during the Nanboku-chō period. Chihaya castleand Akasaka castle, permanent castle complexes containing a number of buildings but no tall keep towers, and surrounded by wooden walls, were built by Kusunoki Masashigeto be as militarily effective as possible, within the technology and designs of the time.
Ashikaga shogunate, established in the 1330s, had a tenuous grip on the archipelago, and maintained relative peace for over a century. Castle design and organization continued to develop under the Ashikaga shogunate, and throughout the Sengoku period. Castle complexes became fairly elaborate, containing a number of structures, some of which were quite complex internally, as they now served as residences, command centers, and a number of other purposes.
Ōnin Warwhich broke out in 1467, however, marked the beginning of a period of nearly 150 years of widespread warfare (called the Sengoku period) between daimyō (feudal lords) across the entire archipelago. For the duration of the Ōnin War (1467-1477), and into the Sengoku period, the entire city of Kyoto became a battlefield, and suffered extensive damage. Noble family mansions across the city became increasingly fortified over this ten year period, and attempts were made to isolate the city as a whole from the marauding armies of samurai which would dominate the landscape for over a century. [Sansom, George. "A History of Japan 1334-1615". Stanford: Stanford University Press, 1961. pp223-227.]
As regional officials and others became the daimyō, and the country descended into war, they began to quickly add to their power bases, securing their primary residences, and constructing additional fortifications in tactically advantageous or important locations. Originally conceived as purely defensive (martial) structures, or as retirement bunkers where a lord could safely ride out periods of violence in his lands, over the course of the Sengoku period, many of these mountain castles developed into permanent residences, with elaborate exteriors and lavish interiors.
The beginnings of the shapes and styles now considered to be stereotypical "classic" Japanese castle design emerged at this time, and castle towns (城下町, "
jōkamachi", lit. "town below castle") also appeared, grew and developed. Despite these developments, though, for most of the Sengoku period castles remained essentially larger, more complex versions of the simple wooden fortifications of centuries earlier. It was not until the last thirty years of the period of war that drastic changes would occur to bring about the emergence of the type of castle typified by Himeji castle, the Imperial Palace, and other castles surviving today. This period of war culminated in the Azuchi-Momoyama period, which saw some of the largest battles in the pre-modern world, and saw great advances in military technology, strategy and tactics.
Europe, where the advent of cannonspelled the end of the age of castles, Japanese castle-building was spurred, ironically, by the introduction of firearms. Though firearms first appeared in Japan in 1543, and castle design almost immediately saw developments in reaction, Azuchi castle, built in the 1570s, was the first example of a largely new type of castle, on a larger, grander scale than those which came before, boasting a large stone base (武者返し, "musha-gaeshi"), a complex arrangement of concentric baileys (丸, "maru"), and a tall central tower. In addition, the castle was located on a plain, rather than on a densely forested mountain, and relied more heavily on architecture and manmade defenses than on its natural environment for protection. These features, along with the general appearance and organization of the Japanese castle, which had matured by this point, have come to define the stereotypical Japanese castle. Along with Hideyoshi's Fushimi-Momoyama castle, Azuchi lends its name to the brief Azuchi-Momoyama period(roughly 1568-1600) in which these types of castles, used for military defense, flourished.
The introduction of the
arquebusbrought dramatic shifts in battle tactics and military attitudes in Japan. Though these shifts were complex and numerous, one of the concepts key to changes in castle design at this time was that of battle at range. Though archery duels traditionally preceded samurai battles since the Heian periodor earlier, exchanges of fire with arquebuses had a far more dramatic effect on the outcome of the battle; hand-to-hand fighting, while still extremely common, was diminished by the coordinated use of firearms. Oda Nobunaga, one of the most expert commanders in the coordinated tactical use of the new weapon, built his Azuchi castle, which has since come to be seen as the paradigm of the new phase of castle design, with these considerations in mind. The stone foundation resisted damage from arquebus balls better than wood or earthworks, and the overall larger scale of the complex added to the difficulty of destroying it. Tall towers and the castle's location on a plain provided greater visibility from which the garrison could employ their guns, and the complex set of courtyards and baileys provided additional opportunities for defenders to retake portions of the castle that had fallen.cite journal|last=Brown|first=Delmer |year=1948|title=The Impact of Firearms on Japanese Warfare, 1543-1598|journal=Far Eastern Quarterly|volume=7|issue=No 3|pages=pp. 236–253|doi=10.2307/2048846]
Cannon were rare in Japan due to the expense of obtaining them from foreigners, and the difficulty in casting such weapons themselves as the foundries used to make bronze temple bells were simply unsuited to the production of iron or steel cannon. The few cannon that were used were smaller and weaker than those used in European sieges, and many of them were in fact taken from European ships and remounted to serve on land; where the advent of cannon and other artillery brought an end to stone castles in Europe, wooden ones would remain in Japan for several centuries longer. A few castles boasted 'wall guns', but these are presumed to be little more than glorified arquebuses, lacking the power of a true cannon. When siege weapons were used in Japan, they were most often
trebuchets or catapults in the Chinese style, and they were used as anti-personnel weapons. There is no record that the goal of destroying walls ever entered into the strategy of a Japanese siege. In fact, it was often seen to be more honorable, and more tactically advantageous on the part of the defender for him to lead his forces into battle outside the castle. When battles were not resolved in this way, out in the open, sieges were almost always undertaken purely by denying supplies to the castle, an effort which could last years, but involved little more than surrounding the castle with a force of sufficient size until a surrender could be elicited.
The crucial development that spurred the emergence of a new type of defensive architecture was, thus, not cannon, but the advent of firearms.
Arquebusfiring squads and cavalry charges could overcome wooden stockades with relative ease, and so stone castles came into use.
Azuchi was destroyed within years of its completion, but it nevertheless ushered in a new period of castle-building; among the many castles built in the ensuing years was Hideyoshi's
Osaka castle, completed in 1583. This incorporated all the new features and construction philosophies of Azuchi, and was larger, more prominently located, and longer-lasting. It was the last bastion of resistance against the establishment of the Tokugawa shogunate (see Siege of Osaka), and remained prominent if not politically or militarily significant, as the city of Osakagrew up around it, developing into one of Japan's primary commercial centers.
Though stone was sometimes used to shore up defenses or foundations for a few centuries prior, Azuchi's distinctive style of stone base was the first of its kind, and was seen in every castle constructed afterwards. The Japanese used cannon very infrequently, and thus, despite the relatively fragile wooden buildings which comprised the castle complex, the heavy stone foundations were often more than sufficient to repel arquebus fire. Whether intentionally or not, these foundations also proved very resilient against Japan's frequent earthquakes.Fact|date=March 2007
This period saw the climax of earlier developments towards larger buildings, more complex and concentrated construction, and more elaborate design, both externally and in the castles' interiors. European castle design began to have an impact as well in this period, though the castle had long been in decline in Europe by this point.
In Japanese politics and warfare, the castle served not only as a fortress, but as the residence of the daimyō, or feudal lord, and as a symbol of his power. Fushimi-Momoyama castle, which was meant to serve as a luxurious retirement home for Toyotomi Hideyoshi, serves as a popular example of this development. Though it resembled other castles of the period on the outside, the inside was extremely lavishly decorated, and the castle is famous for having a tea room covered in gold leaf. Fushimi was by no means an exception, and many castles bore varying amounts of golden ornamentation on their exteriors. Osaka castle was only one of a number of castles which boasted golden roof tiles, and sculptures of fish, cranes, and tigers. Certainly, outside of such displays of precious metals, the overall aesthetics of the architecture and interiors remained extremely important, as they do in most aspects of Japanese culture.
Some especially powerful families controlled not one, but a whole string of castles, consisting of a main castle ("honjō") and a number of satellite castles ("shijō") spread throughout their territory. Though the "shijō" were sometimes full-fledged castles with stone bases, they were more frequently fortresses of wood and earthenworks. Often, a system of fire beacons, drums, or conch shells was set up to enable communications between these castles over a great distance. The Hōjō family's
Odawara Castleand its network of satellites was one of the most powerful examples of this "honjō-shijō" system; the Hōjō controlled so much land that a hierarchy of sub-satellite networks was createdcite book|last=Turnbull|first=Stephen|year=1998|title=The Samurai Sourcebook|location=London|publisher=Cassell & Co]
Toyotomi Hideyoshi's invasions of Korea took place between 1592 and 1598, at the same time as the high point in Azuchi-Momoyama style castle construction within Japan. Many Japanese castles (called "Wajō" 倭城 in Japanese and "Waeseong" in Korean) were built along the southern shores of Korea. All that remains of these castles today are the stone bases.
Sengoku period, roughly a century and a half of war which saw great changes and developments in military tactics and equipment, as well as the emergence of the Azuchi-Momoyama style castle, was followed by the Edo period, over two hundred and fifty years of peace, beginning around 1600-1615 and ending in 1868. Edo period castles, including those which survived from the preceding Azuchi-Momoyama period, therefore no longer had defense against outside forces as their primary purpose. Rather, they served primarily as luxurious homes for the daimyō, their families and retainers, and to protect the daimyō, and his power base, against peasant uprisings and other internal insurrections. The Tokugawa shogunate, in order to forestall the amassing of power on the part of the daimyō, enforced a number of regulations limiting the number of castles to one per "han" (feudal domain), with a few exceptions, [ Satsuma Domainin Kyūshū, one of the wealthiest and most powerful domains, doled out sub-fiefs and was allowed by the shogunate to maintain a number of subsidiary castles within their domain; this came largely out of their power and the inability of the shogunate to effectively enforce many policies in Satsuma. (Sakai, Robert. “Feudal Society and Modern Leadership in Satsuma-han.” "Journal of Asian Studies" 16:3 (May 1957), p366-7.)] and a number of other policies including that of " sankin kōtai". Though there were also, at times, restrictions on the size and furnishings of these castles, and many daimyō grew quite poor later in the period, daimyō nevertheless sought as much as possible to use their castles as representations of their power and wealth. The general architectural style did not change much from more martial times, but the furnishings and indoor arrangements could be quite lavish.
This restriction on the number of castles allowed each "han" had profound effects not only politically, as intended, but socially, and in terms of the castles themselves. Where members of the samurai class had previously lived in or around the great number of castles sprinkling the landscape, they now became concentrated in the capitals of the "han" and in
Edo; the resulting concentration of samurai in the cities, and their near-total absence from the countryside and from cities that were not feudal capitals (Kyoto and Osaka in particular) were important features of the social and cultural landscape of the Edo period. Meanwhile, the castles in the "han" capitals inevitably expanded, not only to accommodate the increased number of samurai they now had to support, but also to represent the prestige and power of the daimyō, now consolidated into a single castle. Edo castle, expanded by a factor of twenty between roughly 1600 and 1636 after becoming the shogunal seat, though obviously something of an exception, the shogun not being a regular daimyō, nevertheless serves as a fine example of these developments. These vastly consolidated and expanded castles, and the great number of samurai living, by necessity, in and around them, thus led to an explosion in urban growth in 17th century Japan.Fact|date=March 2007
As contact with Western powers increased in the middle of the 19th century, some castles such as
Goryōkaku castlein Hokkaidōwere turned once again to martial purposes. No longer needed to resist samurai cavalry charges, or arquebus squads, attempts were made to convert Goryōkaku, and a handful of other castles across the country, into defensible positions against the cannon of Western naval vessels.
Castles in Japan today
All castles, along with the feudal domains themselves, were turned over to the Meiji government in the 1871
abolition of the han system, but few if any were destroyed at that time. Many of the castles remaining in Japan today are reconstructions, some of them made primarily of concrete and designed only to represent or resemble the original wooden structures. Nevertheless, all castles, along with a number of sites of historical or natural significance, are protected under a series of laws promulgated for that purpose. The first came in 1919, and was followed ten years later by the 1929 National Treasure Preservation Law.Fact|date=March 2007
Many castles were destroyed in
World War II, along with much of their surrounding cities. Those which survived were declared National Treasures of Japanin 1951. Many of those destroyed were rebuilt, and some were reopened as museums.
Architecture and defenses
Japanese castles came to be built in a variety of environments, but all were constructed within variations of a fairly well-defined architectural scheme. "Yamashiro", or "mountain castles" were the most common, and provided the best natural defenses. However, castles built on flat plains (平城, "hirashiro") and those built on lowlands hills (平山城, "hirayamashiro") were not uncommon, and a few very isolated castles were even built on small natural or artificial islands in lakes or the sea, or along the shore.
Walls and foundations
Japanese castles were almost always built atop a hill or mound, and often an artificial mound would be created for this purpose. This not only aided greatly in the defense of the castle, but also allowed it a greater view over the surrounding land, and made the castle look more impressive and intimidating. In some ways, the use of stone, and the development of the architectural style of the castle, was a natural step up from the wooden stockades of earlier centuries. The hills gave Japanese castles sloping walls, which many argue helped (incidentally) to defend them from Japan's frequent earthquakes. There is some disagreement among scholars as to whether or not these stone bases were easy to scale; some argue that the stones made for easy hand- and footholds., while others retort that the bases were steep, and individual stones could be as large as twenty feet high, making them difficult if not next to impossible to scale.
Thus, a number of other measures were invented to keep attackers off the walls, including pots of hot sand, gun emplacements, and arrow slits from which defenders could fire at attackers while still enjoying nearly full cover. Spaces in the walls for firing from were called "sama"; Arrow slits were called "yasama", gun emplacements "tepposama" and the rarer, later spaces for cannon were known as "taihosama"Ratti, Oscar and Adele Westbrook (1973). Secrets of the Samurai. Edison, NJ: Castle Books.] Unlike in European castles, which had walkways built into the walls, in Japanese castles, the walls' timbers would be left sticking inwards, and planks would simply be placed over them to provide a surface for archers or gunners to stand on. This standing space was often called the "ishi uchi tana" or "stone throwing shelf." Other tactics to hinder attackers' approaches to the walls included
caltrops, bamboo spikes planted into the ground at a diagonal, or the use of felled trees, their branches facing outwards and presenting an obstacle to an approaching army. Many castles also had trapdoors built into their towers, and some even suspended logs from ropes, to be dropped on attackers.
The Anō family from
Ōmi Provincewere the foremost castle architects in the late 16th century, and were renowned for building the 45-degree stone bases, which began to be used for keeps, gatehouses, and corner towers, not just for the castle mound as a whole.
Japanese castles, like their European cousins, featured massive stone walls and large moats. However, walls were restricted to the castle compound itself; they were never extended around a "jōkamachi" (castle town), and only very rarely were built along borders. This comes from Japan's long history of not fearing invasion, and stands in stark contrast to philosophies of defensive architecture in Europe, China, and many other parts of the world. [Consider, for example, defenses such as
Hadrian's Walland the Great Wall of China, as well as the city walls built throughout Europe and England across history, by the Romans and for centuries afterwards, along with comparable examples in China and elsewhere.] Even within the walls, a very different architectural style and philosophy applied, as compared to the corresponding European examples. A number of tile-roofed buildings, constructed from plaster over skeletons of wooden beams, lay within the walls, and in later castles, some of these structures would be placed atop smaller stone-covered mounds. These wooden structures were surprisingly fireproof, as a result of the plaster used on the walls. Sometimes a small portion of a building would be constructed of stone, providing a space to store and contain gunpowder.
Though the area inside the walls could be quite large, it did not encompass fields or peasants' homes, and the vast majority of commoners likewise lived outside the castle walls. Samurai lived almost exclusively within the compound, those of higher rank living closer to the daimyō's central keep. In some larger castles, such as Himeji, a secondary inner moat was constructed between this more central area of residences and the outer section where lower-ranking samurai kept their residences. Only a very few commoners, those directly in the employ and service of the daimyo or his retainers, lived within the walls, and they were often designated portions of the compound to live in, according to their occupation, for purposes of administrative efficiency. Overall, it can be said that castle compounds contained only those structures belonging to the daimyo and his retainers, and those important to the administration of the domain.
The primary method of defense lay in the arrangement of the baileys, called "maru" (丸) or nihongo|
kuruwa|曲輪. "Maru", meaning 'round' or 'circle' in most contexts, here refers to sections of the castle, separated by courtyards. Some castles were arranged in concentric circles, each "maru" lying within the last, while others lay their "maru" in a row; most used some combination of these two layouts. Since most Japanese castles were built atop a mountain or hill, the topography of the location determined the layout of the "maru".
The most central bailey, containing the keep, was called "honmaru" (本丸), and the second and third were called "ni-no-maru" (二の丸) and "san-no-maru" (三の丸) respectively. These areas contained the main tower and residence of the "daimyō", the storerooms ("kura"), and the living quarters of the garrison. Larger castles would have additional encircling sections, called "soto-guruwa" or "sōguruwa". [While "maru" (丸) most literally translates simply to "round" or "circle", "kuruwa" denotes an area enclosed by earthworks or other walls, and was a term also used to denote the enclosed
red-light districts such as the Yoshiwaraduring the Edo period. As it relates to castles, most castles had three "maru", main baileys, which could be called "kuruwa"; additional areas beyond this would be called "sotoguruwa" (外廓), or "kuruwa which are outside."] At many castles still standing today in Japan, only the "honmaru" remains. Nijō Castlein Kyoto is an interesting exception, in that the "ni-no-maru" still stands, while all that remains of the "honmaru" is the stone base.
The arrangement of gates and walls sees one of the key tactical differences in design between the Japanese castle and its European counterpart. A complex system of a great many gates and courtyards leading up to the central keep serves as one of the key defensive elements. This was, particularly in the case of larger or more important castles, very carefully arranged to impede an invading army and to allow fallen outer portions of the compound to be regained with relative ease by the garrisons of the inner portion. The defenses of Himeji castle are an excellent example of this. Since sieges rarely involved the wholesale destruction of walls, castle designers and defenders could anticipate the ways in which an invading army would move through the compound, from one gate to another. As an invading army passed through the outer rings of the Himeji compound, it would find itself directly under windows from which rocks, hot sand, or other things could be dropped, and also in a position which made them easy shots for archers in the castle's towers. Gates were often placed at tight corners, forcing a
bottleneckeffect upon the invading force, or even simply at right angles within a square courtyard. Passageways would often lead to blind alleys, and the layout would often prevent visitors (or invaders) from being able to see ahead to where different passages might lead. All in all, these measures made it impossible to enter a castle and travel straight to the keep. Invading armies, as well as, presumably, anyone else entering the castle, would be forced to travel around and around the complex, more or less in a spiral, gradually approaching the center, all while the defenders prepared for battle, and rained down arrows and worse upon the attackers.
All of that said, however, castles were rarely forcibly invaded. It was considered more honorable, and more appropriate, for a defender's army to sally forth from the castle to confront his attackers. When this did not happen, sieges were most often performed not through the use of siege weapons or other methods of forced entry, but by surrounding the enemy castle and simply denying food, water, or other supplies to the fortress. As this tactic could often take months or even years to see results, the besieging army sometimes even built their own castle or fortress nearby. This being the case, "the castle was less a defensive fortress than a symbol of defensive capacity with which to impress or discourage the enemy". It of course also served as the lord's residence, a center of authority and governance, and in various ways a similar function to military
The castle keep, usually three to five stories tall, is known as the "tenshukaku", and may be linked to a number of smaller buildings, also called "tenshukaku", of two or three stories. Some castles, notably Azuchi, had keeps of as many as seven stories. The tallest and most elaborate building in the complex, and often also the largest, the keep was the residence of the daimyō and his central command post. Interestingly, the number of stories and building layout as perceived from outside the keep rarely corresponds to the actual internal layout; for example, what appeared to be the third story from outside may have in fact been the fourth. This certainly must have helped to confuse attackers, preventing them from knowing which story or which window to attack, and likely disorienting the attacker somewhat once he made his way in through a window.
The least militarily equipped of the castle buildings, the keep was defended by the walls and towers, and its ornamental role was never ignored; few buildings in Japan, least of all castle keeps, were ever built with attention to function purely over artistic and architectural form. Keeps were meant to be impressive not only in their size and in implying military might, but also in their beauty and the implication of a daimyō's wealth. Though obviously well within the general sphere of
Japanese architecture, much of the aesthetics and design of the castle was quite distinct from styles or influences seen in Shintō shrines, Buddhist temples, or Japanese homes. The intricate gables and windows are a fine example of this.
On those occasions when a castle was infiltrated or invaded by enemy forces, the central keep served as the last bastion of refuge, and a point from which counter-attacks and attempts to retake the castle could be made. If the castle ultimately fell, certain rooms within the keep would more often than not become the site of the "
seppuku" (ritual suicide) of the daimyō, his family, and closest retainers. Palisades lined the top of the castle's walls, and patches of trees, usually pines, symbolic of eternity or immortality, were planted along them. These served the dual purpose of adding natural beautiful scenery to a daimyō's home, representing part of his garden, and also obscuring the insides of the castle compound from spies or scouts. A variety of towers or turrets, called " yagura" (櫓), placed at the corners of the walls, over the gates, or in other positions, served a number of purposes. Though some were used for the obvious defensive purposes, and as watchtowers, others served as water towers or for moon-viewing. As the residences of purportedly wealthy and powerful lords, towers for moon-viewing, balconies for taking in the scenery, tea rooms and gardens proliferated. These were by no means solely martial structures, but many elements served dual purposes. Gardens and orchards, for example, though primarily simply for the purpose of adding beauty and a degree of luxuriousness to the lord's residence, could also provide water and fruit in case of supplies running down due to siege, as well as wood for a variety of purposes.
