Edo Castle (江戸城 Edo-jō?), also known as Chiyoda Castle (千代田城 Chiyoda-jō?), is a flatland castle that was built in 1457 by Ōta Dōkan. It is located in Chiyoda in Tokyo, then known as Edo, Toshima District, Musashi Province.[1] Tokugawa Ieyasu established the Tokugawa shogunate here. It was the residence of the shogun and location of the shogunate, and also functioned as the military capital during the Edo period of Japanese history. After the vacation of the shogun and the Meiji Restoration, it became the Tokyo Imperial Palace. Some moats, walls and ramparts of the castle survive to this day. However, the grounds were more extensive during the Edo period, with Tokyo Station and the Marunouchi section of the city lying within the outermost moat. It also encompassed Kitanomaru Park, the Nippon Budokan Hall and other landmarks of the surrounding area.

The warrior Edo Shigetsugu built his residence in what is now the Honmaru and Ninomaru part of Edo Castle, around the end of the Heian or the beginning of the Kamakura period. The Edo clan perished in the 15th century as a result of uprisings in the Kantō region, and Ōta Dōkan, a retainer of the Ogigayatsu Uesugi family, built Edo Castle in 1457.

The castle later came under the control by the Late Hōjō clan. The castle was vacated in 1590 due to the Siege of Odawara. Tokugawa Ieyasu made Edo Castle his base after he was offered eight eastern provinces by Toyotomi Hideyoshi.[1] He later defeated Toyotomi Hideyori, son of Hideyoshi, at the Siege of Osaka in 1615, and emerged as the political leader of Japan. Tokugawa Ieyasu received the title of Seii Taishōgun in 1603, and Edo became the center of Tokugawa's administration.

Initially, parts of the uninhabitable area were lying under water. The sea reached the later Nishinomaru area of Edo Castle, and Hibiya was a beach.[clarification needed] The land was changed for the construction of the castle.[2] Most construction started in 1593 and completed in 1636 under the grandson Tokugawa Iemitsu. By this time, Edo had a population of 150,000.[3]

The grounds extended with the addition of Nishinomaru, Nishinomaru-shita, Fukiage, and Kitanomaru areas to the existing Honmaru, Ninomaru, and Sannomaru areas. The perimeter measured 16 km.

The daimyō were required by the shōgun to supply building materials or finances, a method used by the shogunate to keep the powers of the daimyo in check. Large granite stones were moved from afar, the size and number of the stones depend on the wealth of the daimyo. The wealthier ones had to contribute more. Those who did not supply stones were required to contribute labor in tasks, such as digging the large moats and flattening hills. The earth that was taken from the moats were used as landfill for sea-reclamation or to level the ground. Thus the construction of Edo Castle laid the foundation for parts of the city where merchants were able to settle.

At least 10,000 men were involved in the first phase of the construction and more than 300,000 in the middle phase.[4] When construction ended, the castle had 38 gates. The ramparts were almost 20 meters and the outer walls were 12 meters high. Moats that were throughout the rough concentric circles were dug for further protection. Some moats reached as far as Ichigaya and Yotsuya areas, and parts of the ramparts survived to this day. This area is surrounded by either the sea or the Kanda river, and therefore allow ships to navigate.

Various fires over the centuries damaged or destroyed parts of the castle. Edo and the majority of the buildings were constructed out of wood.

On April 21, 1701, in the Great Pine Corridor (Matsu no Ōrōka) of Edo Castle, Asano Takumi-no-kami drew his short sword and attempted to kill Kira Kōzuke-no-suke for insulting him. This triggered the events involving the Forty-seven Ronin.

After the capitulation of the shogunate in 1867, the inhabitants including the shogun had to vacate the premises. The castle compound was renamed Tokyo Castle (東京城 Tōkei-jō?) [5] in October, 1868, and then renamed Imperial Castle (皇城 Kōjō?) in 1869. In the year Meiji 2 (1868), on the day 23 of the 10th month,[specify] the emperor moved to Tokyo and Edo castle became an imperial palace.[6]

A fire consumed the old Edo Castle on the night of May 5, 1873. The area around the old donjon, which burned in the 1657 Meireki fire, became the site of the new imperial Palace Castle (宮城 Kyūjō?) built in 1888. Some Tokugawa era buildings which were still standing were destroyed to make space for new structures for the imperial government. The imperial palace building itself, however, was not constructed on the same location as the shogun's palace, which was located in the Honmaru, but in the Nishinomaru ward.

The site suffered substantial damage during World War II, and the destruction of Tokyo, in 1945.

Today the site is part of the Tokyo Imperial Palace. The government declared the area an historic site and has undertaken steps to restore and preserve the remaining structures of Edo Castle.

Appearance of Edo Castle[edit]

The plan of Edo Castle was not only large but elaborate. The grounds were divided into various wards, or citadels. The Honmaru was in the center, with the Ninomaru (second compound), Sannomaru (third compound) extending to the east; the Nishinomaru (west compound) flanked by Nishinomaru-shita (outer section) and Fukiage (firebreak compound); and the Kitanomaru (north compound). The different wards were divided by moats and large stone walls, on which various keeps, defense houses and towers were built. To the east, beyond the Sannomaru was an outer moat, enclosing the Otomachi and Daimyo-Koji districts. Ishigaki stone walls were constructed around the Honmaru and the eastern side of the Nishinomaru. Each ward could be reached via wooden bridges, which were buffered by gates on either side. The circumference is subject to debate, with estimates ranging from 6 to 10 miles.[7]

Signs alongside the moat are written with the words "geba" (dismount). The attending daimyo were required to reduce their number of attendants before entering the inner castle compound. Signs with the family names of each entourage identify them (counting from the right side the first panel) from the Okayama Domain, Fukuoka Domain (fourth panel), Kurume Domain (fifth panel), Tottori Domain (sixth panel), Satsuma and Izumi Domains (seventh panel) and the Sendai Domain (eighth panel).

With the enforcement of the sankin-kōtai system in the 17th century, it became expedient for the various daimyo to set up residence in Edo in close proximity to the shogun. Surrounding the inner compounds of the castle were the residences of various daimyo, most of which were concentrated at the Outer Sakurada Gate to the south-east and in the Ōtemachi and Daimyo-Kōji districts east of the castle inside the outer moat. Some residences were also located within the inner moats in the outer Nishinomaru.

The mansions were very elaborate and large, with no expenses spared to construct palaces with Japanese gardens and multiple gates. Each block had four to six of the mansions, which were surrounded by ditches for drainage.[8] Daimyo with lesser wealth were allowed to set up their houses, called bancho, to the north and west of the castle.

To the east and south of the castle were sections that were set aside for merchants, since this area was considered unsuitable for residences. The entertainment district Yoshiwara was also located here.

Gates[edit]

The inner citadels of the castle were protected by multiple large and small wooden gates (mon), constructed in-between the gaps of the stone wall. Not many are left today. From south to southwest to north, the main gates are located at Nijūbashi, Sakurada-mon, Sakashita-mon, Kikyō-mon, Hanzō-mon, Inui-mon, Ōte-mon, Hirakawa-mon and Kitahanebashi-mon. Only the stone foundations of the other gates (meaning the gap left in between the large stone walls for the wooden gates) are still preserved. Large gates, such as the Ōte-mon, had a guard of 120 men, while the smaller gates were guarded by 30 to 70 armed men.

An eye-witness account is given by the French director François Caron from the Dutch colony at Dejima. He described the gates and courts being laid out in such a manner as to confuse an outsider. Caron noted the gates were not placed in a straight line, but were staggered, forcing a person to make a 90 degree turn to pass on to the next gate.[7] This style of construction for the main gates is called masugata (meaning "square"). As noted by Caron, the gate consisted of a square-shaped courtyard or enclosure and a two story gatehouse which is entered via three roofed kōrai-mon. The watari-yagura-mon was constructed at adjacent angles to each side within the gate.[9] All major gates had large timbers that framed the main entry point and were constructed to impress and proclaim the might of the shogunate.

Garrison[edit]

Accounts of how many armed men served at Edo Castle vary. The Spanish Governor-General of the Philippines Rodrigo de Vivero y Velasco gave an eye-witness account in 1608–1609, describing the huge stones that made up the walls and a large number of people at the castle. He claimed to have seen 20,000 servants between the first gate and the shogun's palace. He passed through two ranks of 1,000 soldiers armed with muskets, and by the second gate he was escorted by 400 armed men. He passed stables that apparently had room for 200 horses and an armory that stored enough weapons for 100,000 men.[10]

Honmaru[edit]

The main tower (upper right) with the surrounding Honmaru palace, Bairinzaka, Hirakawaguchi Gate and Ninomaru (lower part)

The Honmaru (本丸) (also spelled Hommaru) was the central, innermost part of the castle containing the donjon and residence of the shogun. The stately and luxurious main buildings of the Honmaru, consisting of the outer, central, and inner halls, were said[who?] to have covered an area of 33,000 square meters during the Kan-ei era (1624–1644). Surrounding the Honmaru were curtain walls, with 11 keeps, 15 defense houses and more than 20 gates.

Honmaru was destroyed several times by fire and reconstructed after each fire. The donjon and main palace were destroyed in 1657 and 1863, respectively, and not reconstructed. Some remains, such as the Fujimi-yagura keep and Fujimi-tamon defense house, still exist.

The Honmaru was surrounded by moats on all sides. To the north separating Honmaru from the Kitanomaru were the Inui-bori and Hirakawa-bori, to the east separating the Ninomaru was the Hakuchō-bori, and to the west and south separating the Nishinomaru were the Hasuike-bori and Hamaguri-bori. Most of these still exist, although the Hakuchō-bori has partly been filled in since the Meiji era.

Kitahanebashi-mon[edit]

Kitahanebashi-mon

Kitahanebashi-mon (北桔橋門?, literally "Northern Drawbridge Gate") is the northern gate to the Honmaru ward, facing Kitanomaru ward across Daikan-cho street. It is also constructed as a masu-gate just like Ōte-mon and Hirakawa-mon, and has a watari-yagura-mon in a left angle. The bridge in front of the gate, which was once a drawbridge during the Edo period, is now fixed to the ground. The metal clasps used to draw the bridge are still attached to the roof of the gate.

Donjon[edit]

Stone foundation of the main tower (tenshu)

The main donjon or tower (known as the tenshudai (天守台?)) was located in the northern corner of the Honmaru ward. Kitahanebashi-mon is located right next to it and was one of the main gateways to this innermost part. The measurements are 41 meters in width from east to west, 45 meters in length from north to south, and 11 meters in height. A five-storey donjon used to stand on this base which was 51 meters in height and was thus the highest castle tower in the whole of Japan, symbolizing the power of the shogun. The donjon and its multiple roofs were constructed in 1607 and ornamented with gold. It was destroyed in the 1657 Fire of Meireki and not reconstructed. The foundations of the donjon are all that is left.

Despite this, jidaigeki movies (such as Abarembo shogun) set in Edo usually depict Edo Castle as having a donjon, and substitute Himeji Castle for that purpose.

A non-profit "Rebuilding Edo-jo Association" (NPO江戸城再建) was founded in 2004 with the aim of a historically correct reconstruction of at least the main donjon. In March 2013 Naotaka Kotake, head of the group, said that "The capital city needs a symbolic building," and that the group planned to collect donations and signatures on a petition in the hope of having the tower rebuilt. A reconstruction blueprint had been made based on old documents. The Imperial Household Agency had not indicated whether it would support the project.[11][12]

Honmaru Palace[edit]

Model of shiro shoin (White study room), used for meetings with imperial messengers

The residential Honmaru Palace (本丸御殿 honmaru-goten?) and the gardens of the shogun and his court were constructed around the castle keep in the Honmaru area. It consisted a series of low-level buildings, connected by corridors and congregating around various gardens, courtyards or lying detached, similar to the structures that can be seen in Nijo Castle in Kyoto today. These structures were used for either residential or governmental purposes such as audiences.

The Honmaru Palace was one story high, and consisted of three sections:

  1. The Ō-omote (Great Outer Palace) contained reception rooms for public audience and apartments for guards and officials;
  2. The Naka-oku (middle interior) was where the shogun received his relatives, higher lords and met his counselors for the affairs of state; and
  3. Ōoku (great interior) contained the private apartments of the shogun and his ladies-in-waiting. The great interior was strictly off-limits and communication went through young messenger boys.[13] The great interior was apparently 1,000 tatami mats in size and could be divided into sections by the use of sliding shōji doors, which were painted in elegant schemes.

Various fires destroyed the Honmaru Palace over time and was rebuilt after each fire. In the span from 1844 to 1863, Honmaru experienced three fires. After each fire, the shogun moved to the Nishinomaru residences for the time being until reconstruction was complete. However, in 1853 both the Honmaru and Nishinomaru burned down, forcing the shogun to move into a daimyo residence. The last fire occurred in 1873, after which the palace was not rebuilt by the new imperial government.

Located behind the Honmaru Palace was the main donjon. Besides being the location of the donjon and palace, the Honmaru was also the site of the treasury. Three storehouses that bordered on a rampart adjoined the palace on the other side. The entrance was small, made with thick lumber and heavily guarded. Behind the wall was a deep drop to the moat below, making the area secure.

Fujimi-yagura[edit]

The Fujimi Yagura (A Turret of The Edo Castle),1659

The Fujimi-yagura (富士見櫓?, literally "Mt. Fuji viewing keep") stands in the south-eastern corner of the Honmaru enceinte and is three storeys high. Fujimi-yagura is one of only three remaining keeps of the inner citadel of Edo Castle, from a total number of originally eleven. The other remaining keeps are Fushimi-yagura (located next to the upper steel bridge of Nijūbashi) and Tatsumi-nijyu-yagura (at the corner of Kikyō-bori moat next to Kikyō-mon gate). It is also called the "all-front-sided" keep because all sides look the same from all directions. It is believed that once Mount Fuji could be seen from this keep, hence the name. Since the main donjon of Edo Castle was destroyed in 1657 and not reconstructed, the Fujimi-yagura took on its role and was an important building during the Edo period. About 150–160 meters north of the Fujimi-yagura is the former site of the Matsu no Ōrōka corridor, scene of dramatic events in 1701 that led to the Forty-seven Ronin incident.

Fujimi-tamon[edit]

Fujimi-tamon

The Fujimi-tamon (富士見多聞?) defense house is located about 120–130 meters north from the Matsu no Ōrōka. This defense house sits on top of the large stone walls overlooking to the Hasuike-bori (Lotus-growing moat). Weapons and tools were stored here. During the Edo period, double and triple keeps (yagura) were constructed at strategic points on top of the stone wall surrounding the Honmaru. In between each keep, a defense house (called tamon) was erected for defensive purposes. There were once 15 of these houses in the Honmaru, of which only the Fujimi-tamon still exists.

Ishimuro[edit]

Ishimuro

North of the Fujimi-tamon is the ishimuro (石室?, literally "stone cellar"), located on a slope. It is about 20 square meters. Its precise purpose is unknown, but since it is located close to the former inner palace storage area, it is believed to have been used for storage of supplies and documents for the shogunate.

Shiomi-zaka[edit]

Shiomi-zaka (潮見坂?) is a slope running alongside today's Imperial Music Department building towards Ninomaru enceinte. In old times apparently the sea could be seen from here, therefore its name.

Ninomaru[edit]

Hamaguri-bori (front),Hasuike-Tatsumi-Sanjū-yagura (left),Tatsumi-Sanjū-yagura(right) before 1870

At the foot of the Shiomi-zaka on the eastern side of the Honmaru lies the Ninomaru (二の丸?, second enceinte) of Edo Castle. A palace for the heirs of the Tokugawa shoguns was constructed in 1639 in the west area and in 1630 it is reported that a garden designed by Kobori Enshu, who was the founder of Japanese landscaping, was located to its south-east. Several fires destroyed whatever stood here and it was not reconstructed. Aside from the Honmaru palace, the Ninomaru was surrounded by 7 keeps, 8 defense houses, approximately 10 gates and other guardhouses. The Tenjin-bori separates a part of the Ninomaru to the Sannomaru.

Several renovations were carried out over the years until the Meiji era. A completely new garden has been laid out since then around the old pond left from the Edo period. Only the Hyakunin-bansho and Dōshin-bansho are still standing.

Dōshin-bansho[edit]

Dōshin-bansho

The dōshin-bansho (同心番所?) is a guardhouse. A big guardhouse was located within the Ōte-mon where today’s security is located. The passageway proceeding west from the guardhouse becomes narrower within the stone walls on both sides. The dōshin-bansho is located on the right side past this passageway. This is where the samurai guardsmen were posted to watch over the castle grounds.

Hyakunin-bansho[edit]

Hyakunin-bansho

There is a big stone wall in front of the Dōshin-bansho, which is the foundation of the Ōte-sanno-mon watari-yagura keep. The long building to the left on the southern side of this foundation is the hyakunin-bansho (百人番所?). The Hyakunin-bansho is so-called because it housed hundred guardsmen closely associated with the Tokugawa clan.

Ō-bansho[edit]

Ō-bansho

The large stone wall in front of the Hyakunin-bansho is all that is left of the Naka-no-mon watari-yagura (Inner Gate Keep). This building to the inner-right side of the gate is the Ō-bansho (大番所?). As the Honmaru enceinte was said to begin right behind the Naka-no-mon gate, the Ō-bansho probably played a key role in the security of Edo Castle.

Suwa-no-Chaya[edit]

Suwa-no-Chaya

The Suwa-no-Chaya (諏訪の茶屋?) is a teahouse that was once located in the Fukiage garden during the Edo period. After various relocations in the Meiji era, today it is located in the modern Ninomaru Garden.

Sannomaru[edit]

The sannomaru (三の丸?, third enceinte) is the eastern most enceinte next to the Ninomaru, separated by the Tenjin-bori. Ōte-bori is located to the north, running then south is Kikyō-bori.

Bairin-zaka[edit]

A steep slope, Bairin-zaka (梅林坂?), runs from eastern Honmaru toward Hirakawa-mon in front of the today's Archives and Mausolea Department building. It is said[who?] that Ota Dokan planted several hundred plum trees in 1478 in dedication to Sugawara-no-Michizane. Dokan is said to have built the Sanno-Gongendo here, where two shrines were located when the Tokugawa clan occupied the site. With the erection of the Honmaru of Edo Castle, the shrine dedicated to Sugawara-no-Michizane was moved to Kojimachi Hirakawa-cho and later became known as Hirakawa Shrine. The Sanno Shrine was first moved to Momijiyama of Edo Castle and became its tutelary shrine but was moved again. Today it is known as Hie Shrine.

Hirakawa-mon[edit]

Hirakawa-mon

Hirakawa-mon (平川門?) is said to have been the main gate to the Sannomaru of Edo Castle. It is also said to have been the side gate for maidservants and therefore called the Otsubone-mon. The shape of this gate is in the masugata, similar to the Ōte-mon. However a watari-yagura-mon is built to an adjacent left angle within the kōrai-mon, of which it has two. The other kōrai-mon is located to the west of the watari-yagura-mon which was used as the "gates of the unclean" for the deceased and criminals from within the castle.[9] Outside this gate is a wooden bridge with railings crowned with giboshi-ornamental tops.

Ōte-mon[edit]

Ōte-mon

Ōte-mon (大手門?, literally "Great Hand Gate") was the main gate of the castle. During the reign of the second shogun Tokugawa Hidetada, the castle underwent repairs in the 1620s and the gate is said to have taken its present form at this time, with the help of Date Masamune, lord of Sendai Castle, and Soma Toshitane, lord of Nakamura Castle.

A fire in Edo destroyed the Ōte-mon in January 1657, but was reconstructed in November 1658. It was severely damaged twice, in 1703 and 1855, by strong earthquakes, and reconstructed to stand until the Meiji era. Several repairs were conducted after the Meiji era, but the damage caused by the September 1923 Great Kantō earthquake lead to the dismantling of the watari-yagura and rebuilding of the stone walls on each side of the gate in 1925.

The watari-yagura was burnt down completely during World War II on April 30, 1945. Restoration took place from October 1965 through March 1967, to repair the kōrai-mon and its walls, and the Ōte-mon was reconstructed.

Tatsumi-yagura[edit]

Tatsumi-yagura at Kikyō-bori

The tatsumi-yagura (巽櫓?), also known as sakurada-yagura (桜田櫓?), is a two-storey high keep at the easternmost corner of the Sannomaru and the only keep still remaining in it.

Kikyō-mon[edit]

One of the few gates left of the Ninomaru is the kikyō-mon (桔梗門?), which is also known as the Inner Sakurada-mon, as opposed to the (Outer) Sakurada-mon in the south. The architecture of the tower is a gate and in the kōrai style.

Nishinomaru[edit]

Nishinomaru and Fukiage, residences of the three Tokugawa families (17th century)

The nishinomaru (西の丸?, western ward) was the location of the palaces and residences of the retired shogun and the heir-apparent for a while. The outer part of the Nishinomaru to the east (today's Outer Gardens of the Imperial Palace) was the site of various residences of daimyo. The Nishinomaru is bordered by moats to the west such as the Dōkan-bori, Sakurada-bori and Gaisen-bori to the south, Kikyō-bori and Hamaguri-bori to the north. After each fire in the Honmaru, the shogun normally moved into the Nishinomaru, although it was also destroyed by fire in 1853. On May 5, 1873, the Nishinomaru residence burned down. On its site, the imperial palace was built in the Meiji era.

Sakurada-mon[edit]

Sakurada-mon (left), the place where the Tairō Ii Naosuke was assassinated in 1860

Protecting the Nishinomaru from the south is the large Outer Sakurada-mon (桜田門?). This gate is not to be confused with the Inner Sakurada-mon, also known as Kikyo-mon between Nishinomaru and Sannomaru.

Seimon Ishibashi and Seimon Tetsubashi[edit]

The old bridge before it was replaced with a European-style bridge during the Meiji-era, with the Fushimi-yagura in the back

Two bridges led over the moats. The bridges that were once wooden and arched, were replaced with modern stone and iron cast structures in the Meiji era. The bridges were once buffered by gates on both ends, of which only the Nishinomaru-mon has survived, which is the main gate to today's Imperial Palace.

The bridge in the foreground used to be called Nishinomaru Ōte-bashi (西の丸大手橋?), while the one in the back was called Nishinomaru Shimojō-bashi (西の丸下乗橋?).

After their replacement in the Meiji era, the bridge is now called Imperial Palace Main Gate Stone Bridge (皇居正門石橋 kōkyo seimon ishibashi?)) and Imperial Palace Main Gate Iron Bridge (皇居正門鉄橋 kōkyo seimon tekkyō?), respectively. The iron bridge is also known as Nijūbashi (二重橋?, literally "double bridge"), because the original wooden bridge was built on top of an auxiliary bridge due to the deepness of the moat. The stone bridge is also called Meganebashi (眼鏡橋?, literally "Spectacle Bridge") because of its shape.[14] However, both bridges are often mistakenly collectively called Nijūbashi.[15]

Today both bridges are closed to the public except on January 2 and the Emperor's birthday.

Fushimi-yagura[edit]

Fushimi-yagura (伏見櫓?) is a two-storey keep that still exists at the western corner leading towards the inner Nishinomaru, flanked by two galleries (tamon) on each side. It is the only keep that is left in the Nishinomaru. It comes originally from Fushimi Castle in Kyoto.

Sakashita-mon[edit]

Sakashita-mon

(坂下門?, Sakashita-mon) originally faced the north, but was changed to face the east in the Meiji era. This tower gate overlooks Hamaguri-bori. The assassination of Nobumasa Ando, a member of the shogun's Council of Elders, occurred outside this gate.

Momijiyama[edit]

Momijiyama (紅葉山?, literally "Maple Mountain") is an area in northern Nishinomaru. The area had shrines dedicated to former shoguns in which ceremonies were conducted in memory of them and were held regularly.

Tokugawa Ieyasu built a library in 1602 within the Fujimi bower[disambiguation needed] of the castle with many books he obtained from an old library in Kanazawa. In July 1693, a new library was constructed at Momijiyama (Momijiyama Bunko).

The so-called "Momijiyama Bunkobon" are the books from that library, which are preserved in the National Archives of Japan today. This group consists chiefly of books published during the Song dynasty, Korean books that were formerly in the possession of the Kanazawa Bunko library, books presented by the Hayashi family as gifts, and fair copies of books compiled by the Tokugawa government.[16][17]

Fukiage[edit]

The fukiage (吹上?, literally "blown clean") is the western area that was made into a firebreak after the great Meireki fire of 1657. The Fukiage is encircled by the Dōkan-bori to the Nishinomaru to the east, the Sakurada-bori to the south, the Hanzō-bori to the west, the Chidorigafuchi to the northwest and the Inui-bori to the north.

Inui-mon[edit]

The Inui-mon (乾門?) was located in the Nishinomaru area next to today's headquarters of the Imperial Household Agency and called Nishinomaru Ura-mon. It was relocated to its present location between the Kitanomaru and Fukiage garden in the Meiji era. It has its name because of its location in the northwestern part of the Imperial Palace grounds.

Hanzōmon[edit]

The Hanzōmon (半蔵門?) is a gate in the kōrai style. The old gate was destroyed by fire during World War II. The Wadakura Gate was moved here in its stead. The Hanzō-mon is the only gate to the Fukiage area from outside today.

Kitanomaru[edit]

Shimizu-mon

The Kitanomaru (北の丸?) is the northern enceinte next to the Honmaru. It was used as a medicinal garden (Ohanabatake) during the shogun's rule. During the 17th century, the Suruga Dainagon residence was located there as well, which was used by collateral branches of the Tokugawa clan. Today this site is the location of the public Kitanomaru Park. Not much is left from the times of the Edo Castle except for two gates, Shimizu-mon and further north Tayasu-mon.

Kitanomaru is surrounded by moats. The Inui-bori and Hirakawa-bori to the south separate it from the Honmaru and Chidorigafuchi to the west.

Modern Tokyo[edit]

The Toranomon (Tiger Gate), demolished in the 1870s

Many place names in Tokyo derive from Edo Castle. Ōtemachi ( (大手町?) "the town in front of the great gate"), Takebashi ( (竹橋?) "the Bamboo Bridge"), Toranomon ( (虎ノ門?) "the Tiger Gate"), Uchibori Dōri ( (内堀通り?) "Inner Moat Street"), Sotobori Dōri ( (外堀通り?) "Outer Moat Street"), and Marunouchi ( (丸の内?) "Within the enclosure") are examples.
