There was another Nagoya Castle which had the same name and was built at the same place as the present Nagoya Castle in the middle 16th century during the Sengoku Period. It is said that the famous warlord Nobunaga Oda was born at the old Nagoya Castle. Nobunaga eventually moved his home base to Kiyosu Castle before the old Nagoya Castle was abandoned. Since then, Kiyosu Castle (about 10km away from Nagoya Castle on the northeast) had been the center of Owari Province (what is now the western part of Aichi Prefecture). In 1609, the Tokugawa Shogunate decided to build a new castle in place of Kiyosu Castle which often suffered from floods. They needed a stronger castle for their relatives to prepare for a battle with the Toyotomi Clan at Osaka Castle. The castle was named Nagoya Castle once again.
The location of Nagoya Castle and Kiyosu Castle
Simple but Strong Castle with one of Largest Main Tower
The area of the castle was very large but built simply and strongly. The center of the castle, the Main Enclosure, was protected on all directions by other enclosures such as the West Enclosure. The Second Enclosure was added on the southeast of the Main Enclosure, which had the Ninomaru Main Hall for the lord of the castle. The largest Third Enclosure was on the south of all other enclosures, which was used as the senior vassals’ houses.

The Main Enclosure had the five-layer Main Tower, one of the largest main towers on record. The two golden grampuses on the top were particularly popular among people. It is said the first generator of them used 215 kilograms of gold. The enclosure also had the Honmaru Main Hall, but it was only for the Shogun’s stay. Actually, just three Shoguns used it. People have been saying that “The castle makes Nagoya what it is.”.
Destruction and Revival
After the Meiji Restoration, the large enclosures such as the Second and Third Enclosures were turned into a Japanese Army base. However, the government decided to maintain around the Main Enclosure as a castle. Many traditional buildings including the Main Tower and the Honmaru Main Hall remained as they were. They were designated as the first National Treasure for a castle in 1930. It is regrettable to say this, but almost all of them were burned down in 1945. Only three turrets and three gates remain now.
After 14 years from the tragedy, people in Nagoya rebuilt the Main Tower which we now see. One third of the fund for rebuilding it came from the citizens’ donation. The appearance of the tower is almost the same as the original one, but it is a modern concrete building on a huge caisson inside the original stone wall base. The original golden grampuses, which were also burned in 1945, were restored at the same time. The present ones include 88 kilograms of gold. In 2018, the Honmaru Main Hall in the Main Enclosure was restored using the original methods. The enclosure is returning to its former appearance.
この城の中心部は、皇居、庭園や公園になりました。
The center of the castle has become Imperial Palace, gardens or parks.
江戸城は内郭と外郭に分かれていました。内郭は内堀の内側にあって城の中心的機能を果たしていて、本丸、北の丸、西の丸といった主要な曲輪から成っていました。その外周は8km近くです。そこには天守、豪華な御殿があり、多くの櫓や門によって警備されていました。現在、内郭は4つの部分に区切られています。一つずつ見ていきましょう。 Edo castle was divided into Naikaku and Gaikaku. Naikaku was the inside of the inner moat, and consisted of the center portion of the castle including primary enclosures such as Honmaru, Kitanomaru, and Nishinomaru. Its perimeter was nearly 8 km. It had the Tenshu keep, luxurious halls, many turrets and gates for security. Now, Naikaku is separated into four parts. Let’s look at each part one by one.
皇居東御苑~Imperial Palace East Garden
ここは、本丸、二の丸、そして三の丸の各曲輪を由来としています。将軍は長年本丸にあった御殿に住んでいましたが、1863年の火災の後は西の丸に移り、本丸には戻りませんでした。明治維新後、明治天皇もまた西の丸に住み続けました。そのため本丸とその周辺は宮内庁によって使われてきました。そして1968年からは、その多くの部分が庭園として公開されています。 It is derived from the enclosures, Honmaru, Ninonaru and Sannomaru. The Shogun usually lived the main hall at Honmaru for many years. But after the fire in 1863, they moved to Nishinomaru, didn’t returned to Honmaru. After the Meiji Restoration, Emperor Meiji also continued to lived in Nishinomaru. So Honmaru and the area around were used for Imperial Household Agency. Many parts of them have lastly been open to the public as the garden since 1968.

It is partly original and the rest has been restored. It is also one of the entrances of the garden. The Imperial Guards will check your baggage. The inside of the gate is Sannomaru.
・大手三の門跡:ここは二の丸の入り口でした。過去には大きな櫓と門の前には内堀がありました。残念なことに全て撤去されてしまいました。 ・The ruins of Ote-Sannomon Gate: this was the entrance of Ninomaru enclosure. There were large turrets around and the inner moat in front of the gate in the past. Unfortunately, they have all been demolished.

・中雀門跡:この門は、本丸御殿に至る最後の門でした。残っている石垣が黒ずんでいるのは1863年の火災による影響のようです。 ・The ruins of Chujaku-mon Gate: this gate was the last one that led to Honmaru main hall. Their remaining stone walls look dark that might have been caused by the fire in 1863.

・天守台石垣:この城には天守がありました。最初の三人の将軍は、先代の天守に代わる自身の天守を築きました。三代目の天守は特に史上最大と言われる程巨大でした。ところが、1657年の明暦大火で焼け落ちてしまいます。その後四代目の天守再建が始まりますが、中止となりました。現在その四代目用の天守台が残っています。 ・The stone walls for Tenshu keep: the castle had the Tenshu keep. The first three Shoguns built their own Tenshu instead of using the previous one. The third Tenshu was especially big which might have been the biggest one in history. However, it was burned down by the great fire of Meireki in 1657. After the fire, the rebuilding of a fourth Tenshu was launched, but canceled. We can now see the prepared Tenshu base for it.
・梅林坂:この城の創始者である太田道灌が梅の木を植え、神社を作った所と言われています。梅林の合間に、より古風な石垣が残ります。 ・Bairin (Plum Grove) Slope: it is said that the founder of the castle, Dokan Ota planted plum trees and built a shrine there. We can now see the trees among older looking stone walls.

皇居外苑~Outer Gardens of the Imperial Palace
ここは「皇居前広場」とも呼ばれています。江戸時代には「西の丸下」と呼ばれており、多くの大名屋敷が建っていました。明治時代に皇室の園地となりましたが、市民にとって親しみのある場所でもありました。皇居がすぐ近くに見えるからです。第二次世界大戦が終わったとき、敗戦を嘆く人たちがここに集まったことで有名です。現在の人たちも似たような状況です。簡単に来れるので、いつも多くの観光客が集まっています。現在ここは一般に公開されています。 It is called “The Palace Plaza” as well. This area was called “Under Nishinomaru” where many halls for lords were in the Edo Period. In the Meiji Era, it was turned into the garden for Imperial Families, but also familiar to citizens because they could see the Imperial Palace closely. At the end of World War II, it became a well known place for people mourning the loss of the war. This idea is similar to people in the present. Many tourists always visit there due to easy access. Now, garden is open to the public.

・皇居正門石橋と現存する伏見櫓の風景:外苑そのものは広大な広場です。なので多くの観光客は皇居と江戸城建物の景色を愛でています。この取り合わせは一番有名なものです。 ・The view of the Palace Stone Bridge and the remaining Fushimi Turret: The garden itself is an extensive square. So many tourists enjoy the views of Imperial Palace and Edo Castle buildings. This is the most popular one.
・桜田門:これは最も有名な江戸城の建物の一つです。1860年に桜田門外の変が起こった所です。幕府大老であった井伊直弼が暗殺され、幕府の権威失墜を招きました。この門は現存しており、重要文化財に指定されています。 ・Sakurada-mon Gate: This is one of the most popular buildings of Edo Castle. Because this is where Sakuradamon Incident in 1860 happened. The chief minster of Shogunate, Naosuke Ii was assassinated and it caused Shogunate’s the authority to decreas. The gate remains now and has been designated as a Important Cultural Property.
北の丸公園~Kitanomaru Park
北の丸曲輪は、本丸の搦め手を北の方角から守る任務があり、とても重要でした。将軍の親族である清水家と田安家が江戸時代の後期に住んでいました。明治維新後は、近衛師団の兵舎がありました。第二次世界大戦後は公園になり、日本武道館や科学技術館などの施設が置かれています。 Kitanomaru enclosure was very important because it had to guard the rear of Honmaru in the north. The Shogun’s relatives, the Simizu and Tayasu clans lived in the late Edo Period. After the Meiji Restoration, the barracks of the Imperial Guard division were there. After the World War II, it became the park where facilities, like Japan Budokan, Science and Technology Museum, are located.

・清水門:清水家の屋敷の門として使われました。とても優れた構造で、重要文化財になっています。この門は、内堀が窪んでいる奥に設置されていて、誰もが長く細い土橋を渡って入らなければなりません。侵入者は堀に沿った塀から反撃されてしまいます。 ・Shimizu-mon Gate: It was used as the gate for Shimizu clan’s hall. It has a excellent structure and has become an Important Cultural Property. The gate is set at the back of the curved inner moat. Everyone has to go on a long and narrow earthen bridge to enter. Invaders were countered by defenders on walls along the moat.
この門はまた2つの「桝形」と呼ばれる方形の区画が外と内両方にありました。守備側は背後から敵を攻撃できたのです。実に強靭な防御力です。私が思うにこの門はもっと有名になってしかるべきです。 The gate also has two square shape blocks called “Masugata” both outside and inside. Defenders were able to counter the enemy from the back. The gate is very strongly defensive. By I think it should be more well-known.
・田安門:ここは田安家の門でした。地下鉄から武道館に行く人は皆、この門を通ります。この門もまた重要文化財に指定されています。 ・Tayasu-mon Gate: It was the gate of Tayasu clan’s hall. Now, all people from the subway station to Budokan go through the gate. It looks just like the Budokan gate. It has also been designated as a Important Cultural Property.
皇居~Imperial Palace
この区域は元々西の丸曲輪と吹上と呼ばれる場所でした。将軍は江戸時代末期に西の丸にある御殿に住んでいました。明治維新のとき、明治天皇はこの御殿に入り、使い続けました。そのため西の丸周辺が皇居になったのです。一般の人は通常皇居には入れませんが、年始や天皇誕生日といった特別な日には一部開放されます。今回は、外側から見ることができる2つの興味ある景色をご紹介します。 This area includes the original Nishinomaru enclosure and a place called Fukiage. The Shogun lived in the hall at Nishinomaru at the end of the Edo Period. During the Meiji Restoration, Emperor Meiji got the hall and continued to use. That’s why Ninomaru around has become Imperial Palace. Visitors can’t usually enter the palace, but it is partly open to people on special days such as New Year Celebration and the Emperor’s birthday. This time, I will show you two of interesting views of the area from outside.

・千鳥ヶ淵:ここは今は内堀の一部になっていますが、元来は川だったようです。「淵」はこの場合、水流をせき止めて作った沼を意味します。この堀は全国的に桜の名所として知られています。春になると、堀の上にはボートで花見をする人たちで溢れます。 ・Chidori-ga-Fuchi moat: it is now a part of the inner moat, but seemed to be originally a river. “Fuchi” means a lake made by damming the water in this case. The moat is known around the whole country for cherry blossoms. A lot of people seeing them are on the boats in the moat in the early spring.
・半蔵門~この名前は、この門を警護していた忍者の頭領、服部半蔵に由来します。外側から門に伸びる土橋はまるでダムのように見えます。実際、この橋は水位を維持するために築かれました。橋の片側の水位は反対側よりかなり高くなっています。 ・Hanzo-mon Gate: its name comes from the leader of Ninja, Hanzo Hattori who kept the gate. The earthen bridge from outside to the gate looks just like a dam. Indeed, the bridge was built to hold back the water. You can see the one side of the bridge keep much higher level of the water than the other side.
