50.Hikone Castle Part1

The home base of the Ii Clan, a senior vassal of the shogunate

Location and History

Shogunate sent Ii Clan to Important Military Base

Hikone Castle is located near Biwa Lake in Shiga Prefecture and considered as one of the most popular historical sites in Japan. It has its Main Tower which is one of the twelve remaining and the five national-treasure Main Towers in Japan. It also has five castle buildings which are designated as Important Cultural Properties. The main portion of the castle also remains in a good condition with the buildings above, stone walls, and other structures. Because of it, the castle site has been designated as a National Special Historic Site since 1956.

After the Battle of Sekigahara between Ieyasu Tokugawa and Mitsunari Ishida in 1600, Ieyasu got the power as the ruler of Japan. Ieyasu promoted his senior vassal, Naomasa Ii to the lord of the territory beside Biwa Lake, which Mitsuanri had owned. Naomasa first lived a mountain castle called Sawayama Castle Mitsunari lived. However, Naomasa thought it was not enough because he needed a stronger and more convenient castle. The Toyotomi Clan was still at Osaka Castle and there were many lords in western Japan, who thought their master was Toyotomi, not Tokugawa. They might have gotten together and attacked the Tokugawa Shogunate which Ieyasu established in eastern Japan. Naomasa’s territory was located in the area which could avoid the attack to eastern Japan.

Castle is built as Construction Order by Shogunate

After Naomasa died in 1602, his young son, Naotsugu conducted the new castle’s location with Ieyasu. They finally decided to build it on a low mountain at 50m high near Biwa Lake, which would be called Hikone Castle. The castle was built as a construction order by the shogunate with help of over 10 other lords. In order to hurry to complete the construction, they used waste materials from other abandoned castles like Sawayama Castle. However, the construction continued long since 1603, as the scale of castle was huge.

Hikone Castle was built from the top to the foot of the mountain

The Main Tower, Main Hall and other turrets were built together, surrounded by stone walls, on the ridge of mountain to make it easy to protect. Deep ditches were dug around both edges of the ridge to avoid enemies’ invasions to the center of the castle. Moreover, five long-line stone walls were built along the slopes of the mountain to prevent the enemies from moving smoothly.

The mountain was surrounded by tripled water moats and the Main Gate was built behind them. The gate was open to the southwest direction towards Osaka Castle where the Toyotomi Clan lived. Seri-kawa River flowed out of the moats in this direction, so it could have been the forth moat.

It becomes Castle for Peaceful Time

The castle was completed in 1622, about twenty years after its launch. However, the situation dramatically changed in 1615 during the construction. The Tokugawa Shogunate defeated the Toyotomi Clan in that year. After that, the construction was done only by the Hikone Domain building houses for living and government. As a result, the new Main Hall for the lord was built at the foot of the mountain on the opposite side of the Main Gate. The gate to the hall was called the Front Gate just like a new Main Gate. The castle town was also developed around the castle. They were either connected to Biwa Lake through waterways or ponds for water transportation.

Fortunately, no battles happened at Hikone Castle throughout the peaceful Edo Period. The lord of the castle, Ii Clan also played an important role in the central government as the head of hereditary feudal lords. Out of ten, five heads of the shogun’s council of elders came from the Ii Clan and it happened once in 265 years during that period. The most famous one is definitely Naosuke Ii at the end of the Edo Period. He decided to open more doors to foreign countries by signing the Treaty of Amity and Commerce between the US and Japan in 1858. However, he was unfortunately assassinated by the opposite Ronin outside the Sakurada-mon Gate of Edo Castle in 1860. This incident decreased the power and authority of the Tokugawa Shogunate and would be a trigger of the Meiji Restoration.

21.江戸城その3~Edo Castle Part3

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.

ビル街を背景に桜田門と桜田濠~Sakurada-mon Gate and Sakurada-bori moat with the background of modern buildings

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.

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.

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.

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.

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.

・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.

江戸は、水の都だったのです。
Edo was a city of waterways.

特徴~Features

今となっては、ほとんどの人が東京が水の都とは思わないでしょう。ところが、実は江戸はそうだったのです。徳川氏が江戸に移ってきたとき、江戸城は現在の山の手区域にありました。現在の下町にあたる地域は海の下にあったか、湿地帯でした。そして江戸前島と呼ばれた砂州が存在していました。また、陸地と砂州の間には日比谷入江が入り込んでいました。徳川の家臣団は、江戸前島を横切る運河を掘り、水運の便のために川筋を変更したのです。
These days, most people don’t realize that Tokyo is a city of waterways. However, Edo actually was. When the Tokugawa clan moved into Edo, Edo Castle was in the present uptown area. The present down town area was below the sea or waterlogged. There was a sand bank called Edo-Maeto. There was also the Hibiya arm of the sea between the land and the bank. Tokugawa’s team created a canal across Edo-Maeto and change the route of rivers for water transportation.

日比谷入江から江戸前島の東側に川筋を変更して作られた運河が、日本橋川でした。そこには現在日本橋がかかっています。この橋は昔ながらの姿で知られており、多くの主要道路の出発地点でもあります。
A canal created for changing the route of the river from the Hibiya arm of the sea to east of Edo Maeto is Nihonbashi River, where Nihonbashi Bridge goes across. The bridge is known for a traditional view and the starting point of many major roads.

事実、この橋の下を流れる川は人工物で、それは400年以上前に作られたものなのです。この川からは、江戸前島の中心を通る外堀が分かれていました。
In fact, the river below the bridge is artificial and was created over 400 years ago. From the river, the outer moat separated out trough the center of Edo Maeto.

徳川は、城の敷地を広げるためと防衛上の必要から日比谷入江を埋め立てました。更に、江戸前島の周りの海も市街地の確保のため埋め立てたのです。一方で、海の一部分は埋め残して堀、川や運河としました。結果として、江戸は水路とともに広がっていきました。今だにその痕跡は現代の地図上に残っています。それらをいつくか巡ってみましょう。
Tokugawa reclaimed the Hibiya arm of the sea to expand the ground for the castle as well as the need for defense. They also filled the sea around Edo Maeto to create the city area. Meanwhile, they left part of the sea as moats, rivers and canals. As a result, Edo city was spread with waterways. There are still traces of them on the present map. Let’s see some examples.

その後~Later Life

明治維新後、城の多くの建物は撤去されましたが、多くの水路は残りました。人々がまだ使っていたからです。一例として、東京の魚市場は1923年の関東大震災まで日本橋川沿いにありました。地震の後になって築地に移転したのです。
After the Meiji Restoration, many buildings of the castle were demolished, but many waterways remained, because people still used them. For instance, the fish market in Tokyo was along Nihonbashi River until the Great Kanto Earthquakes in 1923. After that, the market moved to Tsukiji.

昭和の中期に車が普及し、1959年には、1964年の夏のオリンピックが東京で開催されることが決まりました。東京の交通インフラ、特に高速道路を整備するための時間はわずかしかありません。政府は高速道路の用地として残っていた水路を使わざるをえませんでした。買収する必要がないからです。東京のほとんど全ての水路が消え失せました。
In the mid Showa Era, motorization came and it was decided in 1959 that the 1964 summer Olympics in Tokyo would be held. There would be little time to develop the infrastructure for transportation in Tokyo, especially an expressway. The government had to use the remaining waterways as the land for the expressway. Because they didn’t need buy them. Almost all of the waterways in Tokyo died out.

日本橋と日本橋川は歴史的価値があるため、かろうじて残されました。そのため高速道路がその上を走っているのです。日本橋地域の人たちは、古き良き景観を取り戻すため政府に対し高速道路を地下に移すよう請願しています。
Nihonbashi Bridge and Nihonbashi River have survived due to their historical values. That’s why the expressway goes above them. Now, people in the Nihonbashi area urge the government to move the expressway underground to get its good old landscape back.
