30.Takato Castle Part1

The stage for the battle of Takato Castle

Location and History

Castle for governing Ina District

Takato Castle was located in Shinano Province (what is now Nagano Prefecture). The Province was very large, so people often considered it as a group of districts. Ina District was the southern part of the province with a long valley terrain from the north to the south sandwiched by mountains. That’s why people also often call the district the Ina Valley. The valley connected the center of the province such as Suwa District and other provinces in the south such as Mikawa Province. That means Ina District was very important for transportation and governance. Takato Castle was on the edge of the mountains on the east of the valley, which was a good location to govern the district.

Improved by Takeda Clan

The Takato Clan, a local warlord first lived in Takato Castle in the first 16th Century during the Sengoku Period. In 1545, The Takeda Clan of Kai Province from the east capture the castle in the process of invading Shinano Province. Since then, The Takeda Clan sent their relatives as the lords of the castle, such as Katsuyori Takeda who became the last lord of the clan later. They improved the castle during their governance.

The foundation of castle was built using only soil. The edge of the mountains where the castle was located was surrounded by the Mibu and Fujisawa Rivers in the north, south and west. The mountains in the east were visible through the Back Gate. The Main Gate was at the western side of the castle, facing a steep slope. In addition, the castle was protected by tripled moats. The Main Enclosure was inside the Inner Moat, the Second Enclosure was inside the Middle Moat, and the Third Enclosure was inside the Outer Moat.

Battle of Takato Castle happens

In 1582, the Battle of Takato Castle between the Takeda Clan and the Oda Clan happened. Nobunaga Oda, unifying the whole country sent his son, Nobutada Oda with about 50,000 soldiers to Takeda’s territory. On the other hand, Morinobu Nishina, Katsuyori’s little brother was in the castle with only 3,000 defenders. Katsuyori, who was at Shinpu Castle about 70km east of Takato Castle, tried to help his brother, but couldn’t. Because most of his vassals betrayed or escaped before the Takeda Clan was defeated. Morinobu didn’t surrender and had to fight with Oda without help. Nobutada himself instructed his troops and charged into both gates of the castle, while the defenders including women fought a desperate defensive battle. However, they were outnumbered, and the castle finally fell in one day. This battle is regarded as the only resistance during the Oda’s invasion into Takeda’s territory.

Maintained by Takato Domain

There was confusion after Nobunaga’s sudden death, a former Takeda’s retainer, the Hoshina Clan got Takato Castle and became the first lord of the Takato Domain in the Edo Period. The castle also became the government building of the domain. The castle for the domain followed the layout of Takeda’s period, but some turrets and plaster walls were built as a castle in the Early Modern Times. The Hoshina Clan accepted the second Shogun’s son named Masayuki as their successor. He also became a senior vassal of the Tokugawa Shogunate and contributed the stabilization of its governance. He was lastly promoted to the lord of Wakamatsu Castle at Aizu Domain. Takato Castle and Takato Domain were followed by the Torii Clan and finally the Naito Clan. The Naito Clan governed them for a long time between 1691 and 1871.

30.高遠城 その1

「高遠城の戦い」の舞台

立地と歴史

伊那郡を支配する城

高遠城は信濃国(現在の長野県)にありました。この国はとても大きく、そのため度々郡の集合体と見なされました。伊那郡は信濃国南部にあり、山々に挟まれた南北に長く伸びる谷の地形を伴っていました。これにより、この郡はまた、伊那谷とも呼ばれました。この谷は、諏訪郡など信濃国の中心部と、南側の三河国など他の国とをつないでいました。伊那郡は交通や統治を行うにあたってとても重要だったのです。高遠城は谷の東側にある山の端に位置しており、この郡を支配するにはよい立地でした。

武田氏による改修

地元領主であった高遠氏が戦国時代の16世紀に最初に高遠城を拠点としていました。1545年に東方の甲斐国から武田氏が、信濃国に侵攻する過程でこの城を手に入れました。それ以来武田氏は、後に武田最後の領主となった武田勝頼など、親族をこの城の城主として送り込みました。その統治の間、城は改修されました。

この城の基礎部分は土だけで作られていました。この城があった山の端部分は、南北と西方向を、三峰(みぶ)川と藤沢川により囲まれていました。山の東側は、搦手門を通して地続きになっていました。大手門は城の西側にあり、急坂に面していました。更に、この城は三重の堀により守られていました。本丸は内堀の内側に、二の丸は中堀の内側に、三の丸は外堀の内側にありました。

「高遠城の戦い」起こる

1582年、武田氏と織田氏との間で高遠城の戦いが起こりました。天下統一を進めていた織田信長が、息子の織田信忠に約5万の軍勢を預け、武田領に攻めこんだのです。一方、この城にいた勝頼の弟である仁科盛信方にはわずか3千の守備兵しかいませんでした。高遠城の約70km東の新府城にいた勝頼は、弟を助けようとしましたが、叶いませんでした。ほとんどの家臣が、武田氏滅亡の前に裏切るか逃亡してしまったからです。盛信は降伏せず、援護なしで織田と戦うしかありませんでした。信忠は自ら兵を率いて城の両方の門に突撃しましたが、女性子どもを含む守備方は、必死の反撃を試みました。しかしながら、多勢に無勢でついに城は一日で落ちてしまいました。この戦いは、織田の武田領への侵攻の間、唯一の抵抗とされています。

高遠藩により維持される

信長の突然の死の後、混乱状態が訪れます。武田の遺臣であった保科氏は高遠城を確保し、江戸時代には高遠藩の初代藩主となります。この城もまた藩庁となりました。藩時代の城は、武田時代の構造をそのまま引き継いでいましたが、近世の城としていくつか櫓や塀が築かれました。保科氏は、跡継ぎとして2代将軍の息子、正之を受け入れます。彼はまた徳川幕府の重臣にもなり、政治の安定に貢献します。ついには、会津藩の若松城城主として栄転することになりました。高遠城と高遠藩はその後、鳥居氏、そして最終的には内藤氏に引き継がれます。内藤氏は1691年から1871年までの長い間、この地を治めました。

127.Shinpu Castle Part1

The mysterious Takeda’s last castle

Location and History

Katsuyori Takeda moved from Kofu to Simpu

Shinpu Castle was located in what is now Nirasaki City, the northwest part of Yamanashi Prefecture which was called Kai Province. The province was owned by the Takeda Clan for a long time until the late 16th Century and their home base had been located in the Takeda Clan Hall in Kofu, the center of the province. Katsuyori Takeda, the last lord of the clan decided to move his home base to Shinpu Castle in 1581. He moved to the castle within the year.

The move was done for several reasons. First, Takeda’s territory expanded to the west such as Shinano Province (now Nagano Pref.), in order to make Shinpu Castle the center of their territory. Secondly, the large territory made Takeda’s vassals so many that the Takeda Clan Hall and Kofu were too narrow and small for them. Lastly, Katsuyori was threatened by Nobunaga Oda and Ieyasu Tokugawa from the west, after several defeated battles with them such as those of Nagashino Castle and Takatenjin Castle. Katsuyori needed to prepare a stronger castle for a possible invasion from them.

Final version of Takeda Clan’s Method for building Castles

Shinpu Castle was built on a mountain on a long cliff wall called Shichiri-Iwa, which means about 28km long rock, along the Kamanashigawa River on the westerly direction. The eastern side of the castle was also a steep cliff of the mountain. The southern part of the castle had the Main Gate with the large Umadashi which was Takeda’s characteristic defense system. The northern part had this castle’s unique defense system called Degamae with water moats. The back entrance had doubled gates with a square space inside called Masugata. The Main Enclosure, the Second Enclosure, and the Third Enclosure were placed on several tiers to protect the castle. Katsuyori’s Main Hall was built in the Main Enclosure on the top. Overall, the castle could be very defensive even though it was all made of soil.

However, Katsuyori burned the castle by himself and escaped from it in Mar 1582 after only his three-month stay, when he had heard of Takato Castle, located in the west of Shinpu Castle, being captured by Nobunaga’s invasion. Moreover, Katsuyori was defeated by his retainer’s betrayal just after eight days from the escape. So, why did Katsuyori withdraw from the castle?

Why did Katsuyori throw Castle away?

The reason which had been often said was that the castle was still unfinished. For example, the Main Gate was found to have no buildings through excavation. Others point out that Katsyori had only hundreds of his troops including women and children when they escaped because most of his vassals left him. Some remaining senior vassals recommended that he should be accommodated to another castle. For example, Masayuki Sanada offered Sanada’s Iwabitsu Castle in Kozuke Province (now Gunma Pref.). Katsuyori finally took another suggestion from the retainer who would deceive him. Another historian even says Sinpu Castle maybe did not deserve a castle, but a large hall would have been more suitable. This is because it needed more moats for a castle. Only Katsuyori knew the answer.

After Nobunaga was also killed in the Honnoji Incident in June 1582, Ieyasu used Sinpu Castle again for his stronghold to get Kai Province. He succeeded in getting it, used Takeda Clan Hall to govern it, and built Kofu Castle as its new home base before Shinpu Castle was eventually abandoned.
