147.Takatenjin Castle Part2

The Legendary Strength of The Castle

Features

Going to Castle Ruins through steep slope

Today, you can visit the ruins of Takatenjin Castle easily if you have a car. You can park in front of either the Main Route in the south or the Back Route in the north. If you want to get a taste of how tough the castle was, I recommend walking on the Back Route. The route is flat all the way to the foot of the mountain, but it gets very steep on the slope. It goes up and zigzags through rough cliffs for a while. However, when you reach the top, you will see that it is actually flat. After seeing this, you will understand that the natural terrain was more than suitable for the mountain castle.

Western ridge part

The spot you reached is called the Well Enclosure, which is the connecting point of the eastern and western ridges. The eastern ridge is the older part of the castle, which includes the Kane, Matoba, Main, Gozen, and Third Enclosures. These enclosures were built along natural terrain, which was partly surrounded by earthen walls and paths.

The Main Enclosure is at the center and it is the highest point of the castle. You can look down vertically at the steep cliffs anywhere and see a view of Fort Hinodake, one of the Six Takatenjin Forts, from the enclosure. The Third Enclosure is located at the easternmost part of the castle, having a fine view. On a clear and sunny day, you can see a great view of Mt. Fuji in the east.

Eastern ridge part

The western ridge is the newer part of the castle which includes the Western, Babadaira, Second, Dono-o, and Seiro Enclosures. The Western Enclosure is the highest point of the ridge where Takaten Shrine currently stands now, so you can see a good view of the Pacific Ocean in the south. The Babadaira Enclosure is below the Western Enclosure and divided by a ditch. Over the Babadaira Enclosure, there is a narrow path. This path is often referred to as “Inumodori” which translates to “Dogs return” meaning “Dogs cannot go through because it’s too tough”.

The Second, Dono-o and Seiro Enclosures are in a line next to the Western Enclosure, which were fortified by the Takeda Clan. This was because other mountains are connected over the Seiro Enclosure, which could have been attacked from this direction. To prevent this from happening, Takeda built a long dry moat along these enclosures and deep ditches dividing them.

147.高天神城 その2

行ってみると城の精強さがわかります。

特徴、見どころ

急坂を登って城跡へ

現在、車をお持ちなら容易に高天神城跡に行ってみることができます。南側の大手道か北側の搦手道のどちらでも、その手前に駐車場があります。この城の防御力の強さを実感したければ、搦手道の方から歩いてみてはいかがでしょう。搦手道は、山の麓まではずっと平坦なのですが、坂にさしかかるとものすごく急になります。そして、しばらく荒々しい崖の間をぬって曲がりくねって登っていきます。ところが、頂上に着いたとたんまた平坦になります。これらを見てみると、この自然の地形は山城にするにはうってつけだということが理解できるでしょう。

東側の峰部分

そのたどり着いた場所は井戸曲輪という所で、山の東西の峰をつないでいます。東側の峰は城の中では古い部分で、鐘曲輪、的場曲輪、本丸、御前曲輪、三の丸があります。これらの曲輪は自然の地形に沿って配置されていて、一部は土塁や通路によって囲まれています。

本丸は、城の中心部であり、もっとも高い位置にあります。そこから下を見下ろすとどこも急崖になっています。また、高天神六砦の一つ、火ヶ峰(ひがみね)砦跡が見えます。三の丸は城では最も東寄りの場所にあります。ここからの眺めは良く、天気に恵まれれば東の方角に素晴らしい富士山の姿を望めます。

西側の峰は、城の中では新しい部分であり、西の丸、馬場平、二の丸、堂の尾(どうのお)曲輪、井楼(せいろう)曲輪があります。西の丸は、この峰では最高地点にあたり、現在は高天神社が建っています。そして、南の方角には太平洋がよく見えます。馬場平は、西の丸の下に位置し、堀切によって隔てられています。馬場平の向こう側には細い山道が通じています。この道は「犬戻り」と呼ばれていて、文字通り犬さえ通れなくて戻ってくるような険しい道という意味です(高天神城が落城したとき、一人だけこの道から脱出し、武田勝頼に落城したことを知らせたそうです)。

二の丸、堂の尾、井楼曲輪は、西の丸のとなりから一直線に並んでおり、武田氏によって強化された場所です。井楼曲輪から先が他の山につながっており、ここから敵に攻撃される恐れがあったからです。その防止のため、武田方はこれらの曲輪に沿って長い空堀を作り、それぞれを深い堀切で区切りました。

147.Takatenjin Castle Part1

The critical point between the Takeda and Tokugawa Clans

Location and History

Mountain being meant for Castles

Takatenjin Castle was located in Totomi Province which is the modern day the western part of Shizuoka Prefecture. It was a simple mountain castle made of soil, but it had a very good location for controlling the province. Many warlords wanted to capture this castle, as a result, what happened in the castle ultimately decided the destinies of both the Takeda Clan and Tokugawa Clan. The mountain where the castle was built on is only 132m high, about 100m from the foot. However, the ridges of it are complicatedly curved and its slopes are quite steep. Moreover, the top of it is not so large, and the view from the top is very clear. That means small defenders could easily protect this castle from attacks of large troops. This mountain was meant for castles.

Battles between Imagawa, Takeda and Tokugawa Clans

It is uncertain when the castle was first built, but the Imagawa Clan was the latest owner of the castle in the first 16th Century. After the Imagawa Clan’s power weakened, Ieyasu Tokugawa managed to capture the castle. Shingen Takeda, who was one of the greatest warlords, also wanted this castle, therefore attacked the castle in 1571. however, he failed to do so before his death in 1572. Singen’s son, Katsuyori Takeda tried to achieve this by building Suwahara Castle in 1573, the north region of Takatenjin Castle, as a foothold. Katsuyori assaulted Takatenjin Castle in 1574, then he managed to capture the castle because the defenders surrendered. He was probably at peak of his power having the largest territory and the highest reputation for the clan at that point.

However, the trend quickly changed after Katsuyori was completely defeated in the Battle of Nagashino near Nagashino Castle by the allies of Nobunaga Oda and Ieyasu in 1575. Ieyasu then started to counterattack in order to get the territory in Totomi Province which included Takatenjin Castle one by one. He first took Suwahara Castle away from Katsuyori in 1576. The castle had been the foundation of capturing Takatenjin Castle once for Katsuyori, but became the one for Ieyasu later on. Ieyasu next built a new castle called it Yokosuka Castle, in the west of Takatenjin Castle, in 1578 to supply his troops and avoid Takeda’s effort to supply to Takatenjin. On the other hand, Takeda improved Takatenjin Castle by building earthen walls, dry moats and ditches between enclosures in the western part of the castle. This was the only the part connected to other mountains. As a result, the castle became much stronger. The final battle was on the horizon.

Ieyasu’s careful attack

Unlike Katsuyori, Ieyasu didn’t assault the castle. He probably understood he couldn’t get the castle so easily. He took a long time building many other fortresses around the castle to besiege it. The Six Takatenjin Forts (Fort Ogasayama, Nogasaka, Higamine, Shishigahana, Nakamura, and Mitsuiyama) are well known, but in fact, there were as many as 20 fortresses built. Each fortress had a distinct role, such as supplying like Fort Nakamura or preventing from Takeda’s attack like Fort Higamine, and containing the castle like Fort Sannosan. Therefore, Takatenjin Castle was completely isolated.

Ieyasu’s long-awaited attack of Takatenjin Castle started in 1580, while Katuyori had problems sending his reinforcement to the castle. This was because Katsuyori’s strength decreased and had to prepare for many other enemies. The starving defenders of the castle urged Ieyasu to surrender. However, the leader of the allies, Nobunaga couldn’t accept it, which was a rare case even during the Sengoku Period when many battles happened. In 1581, the defenders made one last desperate attack from the castle and but were eventually defeated before the castle fell in the end.

Turning point of destinies of Ieyasu and Katsuyori

It was said that Nobunaga aimed to ruin Katsuyori’s reputation by showing that Katsuyori couldn’t protect the castle until the last moment. As a matter of fact, when Nobunaga invaded Katsuyori’s territory the next year, almost all retainers of Katsuyori surrendered or escaped from their master without fighting any battles. The battle of Takatenjin Castle would eventually lead to the destruction of the Takeda Clan which may have been a trigger for Ieyasu to be the final ruler of Japan later on.
