3.Matsumae Castle Part1

A unique castle in the last period of them

Location and History

Castle was built at End of Edo Period

Matsumae Castle was located in the southern edge of Hokkaido Island which was called Ezo until the Edo Period. Only the Matsumae Domain ruled the island in the period because the native Ainu people mainly lived there. There were over 200 domains in Japan throughout the period, which required earning over 10 thousand koku of rice in their territory. However, the Matsumae Domain couldn’t earn enough rice at that time due to the cold climate of the island. So instead, the domain was allowed to trade with the Ainu people exclusively by the Tokugawa Shogunate to maintain it. As a result, the shogunate specially considered it as an independent domain. On the other hand, the domain at first wasn’t allowed to have a castle which needed a higher status that it didn’t have. That’s why the domain had only a hall for the lord, called Fukuyama-kan at its home base of Matsumae until around the end of the Edo Period.

The location of the castle

In 1849, the lord of the domain, Takahiro Matsumae, was suddenly ordered by the shogunate to build a new castle, which was rare in the period. This was because foreign ships often came around Japan, which might have threatened the safety of the country. The homebase of the domain faced Tsugaru Channel between Hokkaido and the mainland of Japan, where these ships could sail. The shogunate expected the domain to build the castle as a base for coastal defense. Takahiro chose a famous scholar of military science, Ichigaku Ichikawa for the location and design of the castle. Ichigaku recommended moving their homebase to another place in Hakodate for the castle. He didn’t think that Matsumae was suitable for the castle because of its location on the halfway point of a gentle slope. However, the domain refused it, saying it was too expensive and they didn’t want to leave the familiar environment of Matsumae. Finally, the castle was built by replacing the Fukuyama-kan hall in 1855, which was eventually renamed Matsumae Castle.

Castle is mixed with Traditional Japanese style and Modernized features

Matsumae Castle is one of the latest castles to be built using Japanese style, such as having a Main Tower, turrets and gates built with stone walls in several separated enclosures. The castle actually had the Main Enclosure including the three-level Main Tower, its gate and the Main Hall for the lord. The Second Enclosure with several turrets was also built blow the Main Enclosure. The Third Enclosure with the Front Gate was further below. The Inner and Outer Moats were dug between them. On the other hand, the castle had some advanced and specific features. 7 batteries were built towards the sea in the Third Enclosure as a base for coastal defense. The turrets in the Second Enclosure, such as Taiko-Yagura or the Drum Turret, were used as the command posts for the batteries. The stone walls of the castle were built precisely using a method called Kikko-zumi or the Tortoise Shell style. However, those of the Main Tower were not built high at only around 3m, which made it harder to target for ships with guns. The walls of the tower were also built strongly that can withstand gun attacks.

Castle falls twice during Meiji Restoration

The first battle at the castle happened in 1868 during the Meiji Restoration, but not against foreign ships but rather against Japanese troops. The former Shogunate Army led by Takeaki Enomoto escaped from the main land to Hokkaido and captured Goryokaku in Hakodate and they made it their home base. Then, they sent troops led by Toshizo Hijikata and a fleet to Matsumae Castle. The attackers and the defenders in the castle at first fought each other with cannonade. A ship (Banryu-maru) of the fleet had to withdraw being shot by a battery outside of the castle. However, Hijikata also attacked the side and the back of the castle. In fact, the back side was the weakest point of it. This was because the gentle slope, where it was built on, was easy to attack from the back. Moreover, the Matsumae Domain spent a lot of money on the front facing the sea, but only a few on the back. The castle would eventually fall.

In the next year, the warriors of the domain, who managed to escape to Aomori in the main land, tried to retaliate with the help of the New Government Army to get Matsumae Castle back. They equipped stronger guns with a more modernized fleet than the former Shogunate Army. They landed at Hokkaido again and got close to the castle by fighting. When they attacked the castle from the other side of it, the defender of the former Shogunate Army eventually surrendered.

3.松前城 その1

城の時代の終末期に築かれた、独特な城

立地と歴史

幕末になって築かれた城

松前城は、江戸時代まで蝦夷と呼ばれた北海道の南端にあった城です。その江戸時代には松前藩だけが北海道全島を支配していました。そこには主に多くのアイヌ民族の人たちが住んでいたからです。この時代を通じて日本全国には200を超える藩が存在しており、米の収穫高1万石以上の領地を有する領主だけが藩を有する大名とされたのです。ところが、北海道の寒冷な気候のため、当時の松前藩では米がとれませんでした。その代わりとして藩維持のために、幕府によりアイヌ民族と独占的に貿易を行うことが認められていました。その結果、幕府は特例として松前藩を独立した藩とし見なしました。一方、松前藩は当初城を持つことは許されませんでした。城を持つにはもっと大きな石高か格式が必要とされたためです。よって、松前藩は藩主が住む御殿を持つことだけを許され、その館は幕末近くまで、松前藩の本拠地として福山館と呼ばれました。

城の位置

1849年、藩主の松前崇広(まつまえたかひろ)は突然幕府から新しい城を築くよう命じられました。その当時としては大変珍しいことでした。これは、外国船が頻繁に日本周辺に現れるようになり、国の安全を脅かすことになりかねない状況が原因でした。松前藩の本拠地は北海道と日本本土の間の津軽海峡に面していて、これら外国船が通行することが考えられました。幕府は、松前藩に海岸防備の拠点として新しい城を築くことを期待したのです。崇広は城の立地と設計を、有名な軍学者だった市川一学(いちかわいちがく)に依頼しました。一学は、新しい城を築くのに本拠地を函館の方(庄司山周辺、後の五稜郭よりもっと山側)に移すことを提案しました。彼は、松前は緩やかな坂の途中に立地しているため、城を築くには不適格と考えたのです。ところが、費用がかかりすぎることと、愛着ある松前から離れたくないという理由から、藩はその提案を拒絶しました。最終的には城は福山館を建て替える形で1855年に築かれ、館は松前城と改名されました(別名として福山城ともいいます)。

旧来の日本式と、近代的な特徴が混在

松前城は、いくつかに分かれた曲輪上に石垣とともに天守、櫓、門などを築く日本式城郭としては最後の方に作られた城の一つです。実際にこの城には、三層の天守、門、藩主の御殿があった本丸がありました。いくつもの櫓が築かれた二の丸は、本丸の下の方に作られました。城の正門(沖ノ口門)があった三の丸は更に下方にありました。内堀と外堀がこれらの曲輪の間に掘削されました。一方、この城はいくつもの進化し且つ特徴的な点がありました。三の丸には7つの砲台が海の方に向かって設置され、海防の役割を担っていました。二の丸にあった太鼓櫓などの櫓群は、砲台の指揮所として使われました。城の石垣は、亀甲積みと呼ばれる精密な石積みの方法を用いて築かれました。しかし、天守台の石垣はあまり高くなく、3mくらいしかありませんでした。沖の船からの射撃の的になることを防ぐためです。天守の壁も砲撃に耐えられるよう厚く作られました。

明治維新での戦いで2度の落城

この城での最初の戦いは1868年の明治維新の最中に起こりました。しかし、外国船相手ではなく、日本人の軍勢との戦いでした。榎本武揚に率いられた旧幕府軍が本州から北海道に逃れてきて、函館の五稜郭を占領し、彼らの本拠地としました。そして土方歳三が率いる軍勢と艦隊を松前城に派遣してきたのです。攻撃側と守備側は、最初のうちは互いに砲撃戦を行い、城の外にある砲台からの射撃により、旧幕府軍の一隻(蟠竜丸、ばんりゅうまる)が損傷により退避したほどでした。しかし土方が、城の側面(東側の馬坂口)と背面からも攻撃を行いました。実は背面がこの城の弱点だったのです。もともと緩やかな斜面の上に作られた城であったため、攻撃側は背面から攻撃するのが容易です。それに加えて、松前藩は海に面した正面の方の築造に多額の費用をかけ、背面はほぼ放置した形になってしまっていたのです。城はついに落城してしまいました。

松前藩士たちは本州の青森の方に逃げていましたがその翌年、新政府軍の力を借りて松前城を奪還し、雪辱を果たそうとしていました。彼らはそのときには、旧幕府軍よりも強力な武装を備え、近代化された艦隊を伴っていたのです。そして北海道に再上陸し、戦いを重ねながら松前城に迫りました。ついに松前藩士たちは城のもう一方の側面(西側の湯殿沢口)から城に突入し、旧幕府軍の守備側は降伏することになりました。

133.Samegao Castle Part1

The final place of the Otate Rebellion and Kagetora Uesugi

Location and History

Branch of Kasugayama Castle

Samegao Castle was located on a mountain in the western part of Echigo Province which is now Nigata Prefecture. It is uncertain when the castle was first built, but in the late 16th Century, it was one of the satellite castles of Kasugayama Castle, the home base of Kenshin Uesugi. Kenshin was one of the greatest warlords at that time in Japan, who built the network of castles to protect his home base. Samegao Castle is, in fact, rather well-known as the final battlefield of the Otate Rebellion and the place of Kagetora Uesugi’s death, who was defeated in the rebellion.

Kagetora is adopted from Hojo to Uesugi

Kagetora Uesugi was an adopted child of Kenshin, but had been born as a family member of the Hojo Clan, which fought with Kenshin over the Kanto Region. The reason why Kagetora came to Uesugi was that Uesugi and the Hojo made peace temporarily in 1569 against the Takeda Clan. The Takeda clan broke the alliance of the three clans (Takeda, Imagawa and Hojo) by invading Imagawa territory. The Hojo clan was very angry about it. However, the new alliance between Uesugi and the Hojo lasted for only two years because the Hojo quit and reforged the alliance with the Takeda in 1571. Ordinarily, Kagetora could have been returned to the Hojo, but Kenshin let Kagetora stay as a part of the Uesugi clan for some reason. It is said that Kenshin personally liked Kagetora. Even though no portraits of Kagetora remain, records say he was attractive and looked beautiful.

Two adopted sons are against each other after Kenshin’s death

With the cessation of the alliance with the Hojo, Kenshin adopted another son from his relatives, called Kagekatsu Uesugi. Kenshin seemed to hope that Kagetora would support Kagekatsu and they would cooperate with each other. Many historians also say Kenshin had not clearly decided his successor before his sudden death in March 1578. In fact, these two adopted sons lived in the same Kasugayama Castle as if Kagekatsu was the master for a while after their father’s death. However, the situation didn’t allow them to make peace. The trusted vassals of Kagekatsu, who were the core members of the government, supported him. Other local lords in Echigo Province and some warlords outside the province supported Kagetora because he had come from the outside. Kagetora’s parents’ home, the Hojo and its ally, the Takeda especially wanted him to be the successor. That made the two successor candidates battle each other starting in May 1578, which was called the Otate Rebellion.

Otate or the Palace, was originally the residence for Norimasa Uesugi, who was a former shogunate deputy for the Kanto Region and Kenshin’s foster father. Kagetora escaped from Kasugayama Castle to the residence, about 5km from the castle. It became his home base during the battle for nearly one year. At the beginning of the battle, Kagetora was superior in terms of support to Kagekatsu until the lord of the Takeda, Katsuyori Takeda came to Echigo Province with his troops to support Kagetora in June. However, Kagekatsu let Katsuyori return to his home by giving a lot of money and promising to cede some territories. After that, the situation reversed as Kagekatsu had many native loyal retainers while Kagetora had few because of his career. Kagekatsu finally made a full-scale attack on the Otate Residence before it fell in March 1579. Kagetora escaped and tried to get to Odawara, his parental familial home base, Odawara Castle. He stopped by a castle of his supporter, Munechika Horie, which would be the place of his death. This place was called Samegao Castle.

Kagetora dies in Samegao Castle

Samegao Castle was a satellite castle, but had a large scale because it was on the way to Shinao Province (now Nagano Pref.), south of Echigo, where Kenshin and Shingen Takeda, who was Katsuyori’s father, often battled each other. It was a typical mountain castle at that time, using natural terrain to make it defensive. Many enclosures made of soil were built on the ridges. They were divided by artificial ditches and connected by narrow paths cut vertically on both sides. The routes through the valleys were zigzagged so that enemies could not attack the castle easily.

Even staying in the strong castle, Kagetora was not able to survive without reinforcement from the outside. He was attacked by Kagekatsu’s pursuing troops right away. Some records say Munechika Horie, the lord of the castle also betrayed Kagetora. Kagetora finally committed Harakiri (ritual suicide) at the age of 26 after the castle buildings were burned by the troops.
