Features

Castle Ruins are developed as Karasawayama Shrine

Today, the ruins of Karasawayama Castle have been well developed as Karasawayama Shrine. Many people visit the shrine to pray for something, hike the mountain, see a great view, and recently see lots of friendly cats living in the shrine. These cats seem to have been strayed or abandoned, but are now fed by volunteers and visitors.

Of course, some of the visitors enjoy historical items at the site as well. There are main routes from the foot of the mountain to the top in the south and west, similar to the castle’s period. In addition, the current routes have been developed for both cars and hikers, which means there are at least four routes.

Past and Current Routes

They are not the same as the original routes to the castle. For example, the two paved roads for cars from the two directions gather at the parking lot on the top. However, part of the road from the south was blocked by huge rocks near a remaining rock called Kagami-iwa (meaning the Mirror Rock). The two original paths to the castle gathered in front of the rocks and went to the Main Gate via zigzagging route.

Attractions along Main Route

If you enter the Main Gate Ruins from the parking lot, you will see the ruins have a typical alternating entrance with stone walls (but mainly built or renovated during the Meiji Era). The main route goes to the center inside the gate, but there are also some attractions from side to side. There is another huge rock called Tengu-iwa (meaning the long-nosed goblin rock) on the right (the southern side), which was a lookout and defensive point, and is a great viewing spot. There is also a hill on the left (the northern side), called Hiraishi-yama (meaning the mountain for avoiding enemies’ arrows). It was named after the armor the Sano Clan passed down from Hidesato Fujiwara, their founder. Therefore, it must have been used as another defensive spot.

The map around the castle

If you go ahead to the center on the main route, you will see a large well called Oi-no-ido on the left. It is 9m in diameter and over 8m deep and it still has spring water inside. The castle ruins have other wells, too. They were essential for the castle to be besieged for a long time. You will next see large and long dry moats, called Yotsumebori (meaning the fourth moat), which divided the main portion and the others. Only the fixed concrete arch bridge, called Shinkyo, goes over the moats. It was said to be originally a draw bridge which would have been fallen when a battle happened. People often say Uesugi Kenshin attacked this point but failed.

Four tiered Major Enclosures

The main route as the shrine’s approach goes on right side of the main portion. The portion consists of four tired enclosures, the belt, third, second and main enclosures from the bottom to the top. In particular, the third enclosure is the largest, which was said to be used as a reception room. You can visit it via a side path. There will be a division point of the approach and the original main route. If you go straight on the approach, you will reach below the stone steps of the shrine on the main enclosure. Otherwise, you can turn left and get to the second enclosure. It is recommended for castle visitors to take the latter because you can see the great stone walls of the main enclosure close by on your right.

114.唐沢山城　その２

現在、唐沢山城跡は唐沢山神社としてよく整備されています。多くの人たちが神社を訪れ、何かをお祈りしたり、ハイキングをしたり、素晴らしい景色を楽しんでいます。最近では、神社に住み着いた人懐こい猫たちを見に来る人も多いです。もちろん、ここにある史跡を見に来る人もいます。

特徴、見どころ

唐沢山神社として整備

現在、唐沢山城跡は唐沢山神社としてよく整備されています。多くの人たちが神社を訪れ、何かをお祈りしたり、ハイキングをしたり、素晴らしい景色を楽しんでいます。最近では、神社に住み着いた人懐こい猫たちを見に来る人も多いです。ここにいる猫たちは、もとは野良猫か捨て猫だったようで、ここでボランティアやビジターのよって養われています。

もちろん、ここにある史跡を見に来る人もいます。山麓から山頂へは、城があったときと同じように、南側と西側の２方面から向かいます。補足すると、現在の道は車道とハイキングコースがそれぞれ設定されているので、少なくとも都合４つのルートがあります（実際にはもっと多くのハイキングコースがあります）。

唐沢山周辺の地図

現在と過去のルート

方面は一緒でも現在の道筋は、城時代のオリジナルのものとは違っています。例えば、２方面から来る舗装された車道は、山頂の駐車場の前で合流します。しかし南側から来る道の一部は、現在も残る「鏡岩（かがみいわ）」の近くで、かつては岩によって塞がれていた場所でした。オリジナルの道はこの岩の前で合流し、ジグザグの道を伝って大手門に向かっていました。

大手道沿いの見どころ

駐車場から大手門跡に入っていくと、石垣によって典型的な食い違いの虎口があります（この石垣には実際には明治時代に築かれたか、修繕されたそうです）。大手道は門の内側を中心部に進みますが、その左右にも見どころがあります。右側（南側）には天狗岩という別の巨岩があって、過去には物見台だったのでしょうが現在では素晴らしい見晴台になっています。左側（北側）には避来矢山（ひらいしやま）という丘があるのですが、その名前は佐野氏が先祖の藤原秀郷から受け継いだ鎧（敵の矢を避けることができるという云われがある）から由来しています。したがって、そこも防衛拠点であったのでしょう。

城周辺の地図

大手道をまっすぐ中心部の方に進んでいくと、左側に「大炊井戸（おおいのいど）」という大きな井戸が見えてきます。直径は９ｍあり、深さは８ｍ以上で、今も水が湧き出ています。城跡には他の井戸もあり、かつての長い籠城戦にも耐えられるようになっていました。次には四つ目堀という名の長大な空堀があり、ここから先が城の主要部となります。神橋（しんきょう）というコンクリート製の固定橋のみが堀を渡っています。この橋はもとは曳橋で、戦いが起こったときには外されたと言われています。上杉謙信がここまで攻めてきたが撃退されたとも言われています。

４段の主要曲輪群

大手道は神社の参道にもなっているのですが、城の主要部の右側を通っていきます。その主要部は４段の曲輪群から構成されています。下の方から、腰曲輪、三の丸、二の丸、そして本丸です。特に、三の丸はその中では最大で、かつては接客のための応接間があったと言われています。三の丸へは脇道を通って行きます。参道にはオリジナルの大手道との分岐点があって、まっすぐ参道を行けば本丸にある神社への石段下に着きます。そこを左に曲がっていくと、二の丸の方に行きます。城巡りに来た方であれば、左の方に曲がってください。右側の方に本丸の素晴らしい石垣が見えてきます。

114.Karasawayama Castle Part1

The last lord of the castle, Nobuyoshi Sano built high stone walls on the main portion of the castle, which was a rare case in the region. It must have been done with help from Hideyoshi Toyotomi because he and his retainers had built many similar stone walls in western Japan.

Location and History

Sano Clan builds Castle during Sengoku Period

Karasawayama Castle was located in modern day Sano City, Tochigi Prefecture, which was a large mountain castle beside the northern edge of the Kanto Plain. Tradition says that a famous general, Hidesato Fujiwara built it in 972 during the Ancient times. However, historians think that it was created by the Sano Clan, who were descendants of Hidesato and governed the castle for a long time. According to the results of the research and studies, the clan first lived in a hall at the western foot of the mountain until the 15th Century. It was thought that the castle was built or developed by the clan on the mountain when many battles happened in the Kanto Region, during the Sengoku Period. Other popular mountain castles in the region like Kanayama and Minowa Castles were built at the same time to protect the owners under the severe conditions. The Sano Clan first used the mountain castle in the cases of emergency, but eventually lived in it to survive.

Kenshin Uesugi devotes to capture Castle

On the other hand, great warlords, who wanted to rule over the region, thought they would need to get Karasawayama Castle because of its advantageous location. Kenshin Uesugi was one of them and was devoted to do it. There is a symbolic episode when he first invaded the Kanto Region around 1560. He visited Karasawayama Castle with few vassals, which was surrounded by his enemy, the Hojo Clan’s large troops, to persuade the lord of castle, Masatsuna Sano to support him until he succeeded. However, every time Kenshin returned to his home, Kasugayama Castle in Echigo Province, the Hojo Clan got its territory back and forced local lords to support it. Masatsuna was one of them and he had to switch allegiance.

Kenshin, who is considered one of the strongest generals, got angry and attacked the castle, but was not able to capture it by force as it was really strong. Even when Masatsuna surrendered to Kenshin, they would do the same things after Kenshin went back. As a result, they fought with each other at least five times. Kenshin once banished Masatsuna from the castle and sent his relative and vassals to govern it. However, he finally returned the castle to Masatsuna for some reasons. He might have felt the difficulty of how to control this distant site.

High stone walls are built with help of Hideyoshi Toyotomi

The Kanto Region, including Karasawayama Castle, eventually belonged to the Hojo Clan during the 1570’s and 1580’s. It sent its relative, Ujitada Hojo to govern the castle like Kenshin had used to do. On the other hand, Masatsuna’s relative, Fusatsuna Sano ran away from the region to western Japan to serve Hideyoshi Toyotomi who was the ruler of Japan at that time. Fusatsuna led Hideyoshi to the region when they invaded it in 1590, which resulted in Fusatsuna getting the castle back as the lord. However, Hideyoshi seemed to also want to control the castle. He made the little brother of his close vassal, Nobutaka Tomita to be the successor of Fusatsuna, which would be called Nobuyoshi Sano, the last lord of the clan and the castle. This could be because his rival, Ieyasu Tokugawa was moved by him to the region. He wanted to have Ieyasu monitored by someone reliable.

Karasawayama Castle was built on a large mountain which had several ridges. Lots of enclosures were also built on the top and the ridges which had turrets, lookouts, guard houses and shooting points to monitor and attack enemies. These ridges or enclosures were divided by deep ditches to prevent enemies from invading easily. There are two main routes in the south and west, which gathered at the meeting point in front of the Main Gate near the top, which were controlled by the castle’s soldiers. The foot area was used as the lords and senior vassals’ residences surrounded by thick and long earthen walls for defense. They had been developed and improved by the Sano, Uesugi, and Hojo Clans for a long time.

The castle’s foundations were basically made of soil, which was a common way of building castles in eastern Japan at that time. However, the last lord, Nobuyoshi built high stone walls on the main portion of the castle, which was a rare case in the region. It must have been done with help from Hideyoshi because he and his retainers had built many similar stone walls in western Japan. On the other hand, Ieyasu still didn’t have the techniques and guilds for building such high stone walls. That meant the stone walls of strong Karasawayama Castle must have been a big threat to Ieyasu.

Life of Castle suddenly ends, ordered by Ieyasu Tokugawa

When Ieyasu got the power to be the ruler around 1600 after Hideyoshi died, Nobuyoshi somehow survived by supporting Ieyasu. However, the declinations of Karasawayama Castle and the Sano Clan suddenly occured. In 1602, Ieyasu ordered Nobuyoshi to move from Karasawayama to Sano Castle in a plain area nearby. It was said that the reason for it was that it could be rude for Nobuyoshi to look down on Ieyasu’s home, Edo Castle from the mountain castle. Nobuyoshi was finally fired by Ieyasu in 1614 due to being implicated for a crime of his brother, Nobutaka Tomita. Overall, Ieyasu seemed to want to remove possible rebels like Nobuyoshi with strong castles like Karasawayama.
