114.Karasawayama Castle Part3

The stone walls of the main enclosure entrance are not so high, but use several huge ornament stones.
In addition, the entrance was recently researched and it was found that it had a turret gate. Overall, these structures made the castle stronger as well as more authorized.

Features

Great Stone Walls of Main Enclosure

The stone walls are around 8m high and about 40m long. They were built by piling natural or roughly processed stones in a way called Nozura-zumi. They look rough but really great! It was said that the last lord, Nobuyoshi Sano built them by inviting an excellent guild of stone craftsmen celled Ano-shu from western Japan.

You will eventually enter the second enclosure just below the main enclosure. Therefore, you will see the entrance of the main enclosure, which was also surrounded by great stone walls. They are not so high (at 2.5m), but use several huge ornament stones, called Kagami-ishi (meaning mirror stones).
In addition, the entrance was recently researched and it was found that it had a turret gate. Overall, these structures made the castle stronger as well as more authorized.

The enclosure is on top of the mountain and is used for the shine buildings. It is unknown what buildings it had in the past, but it might have had buildings like the Main Hall and the Main Tower.

Defensive Spots in North and South

There is another enclosure, in the south of the main enclosure, called Nanjo (meaning southern castle). It was built to protect the southern ridge of the mountain where you can see stone walls and dry moats around. The shrine office is on the enclosure and this is another great viewing spot. If the weather is fine, you can enjoy a view of both Tokyo Sky Tree and Mt. Fuji. Nobuyoshi might have had no choice but to accept the shogunate’s close questioning that looking down on Edo Castle from the mountain would be rude.

There is also other enclosures on the northern ridges, such as the Northern Castle. They are basically made of soil, divided by earthen ditches and connected by earthen bridges, which were older parts of the castle.

Hiking Course has other Castle Ruins

For hikers, it is recommended to try part of Karasawayama Shuyu(Round) Course, from the castle to Imori-yama Mountain via the Kagami-iwa Rock, Byobu-iwa Rock and Gongen-do Hall Ruins. The course is on another ridge connected to the Karasawayama Mountain, which was a defense point for the castle.

That’s why you can see a set of a narrow bridge with artificial ditches on the way. You can also enjoy a great view of the whole Kanto Region on each peak of the ridge. The Imori Mountain is where Kenshin Uesugi and Masatsuna Sano fought against each other in their last battle in 1570.

Later History

After the Sano Clan was banished by the Tokugawa Shogunate, the Ii Clan which was a senior vassal family of the shogunate owned the Sano area as its detached territory during the Edo Period. The clan banned people from entering the mountain, the former castle area. That’s why the ruins of the castle have been preserved in a good condition. After the Meiji Restoration, locals established the Karasawayama Shrine in 1883. Establishing shrines on castle ruins was a popular way to maintain them at that time. The ruins also became part of Karasawayama Prefectural Natural Park in 1965. That’s why several approaches and hiking courses have been developed there. As for castle ruins, Sano City has been researching and studying them since 2007. As a result, they were designated as a National Historic Site in 2014.

My Impression

The current people often say Kenshin Uesugi attacked Karasawayama Castle and approached its main enclosure, but failed. Meanwhile, Kenshin himself wrote on his letter in 1567 when he owned the castle and was attacked by the Hojo Clan that “Only the Main Enclosure remained”. I’m not sure if similar things happened twice whether the people misunderstood Kenshin’s sides. Either way, Kenshin and the castle were closely involved. I think the people are still borrowing his name even today to explain about the strength of the castle.

How to get There

If you want to visit the castle ruins by car, it is about a 10-minute drive away from Sano-Tanuma IC on the Kitakanto Expressway.
There are parking lots at the foot, the mid slope and top of the mountain.
By public transportation, it takes about 40 minutes on foot from Tanuma Station on the Tobu-Sano Line to the top.
From Tokyo to the station: take the train on the Joban Line from Tokyo or Ueno Stations, transfer to the Tobu-Isesaki Line at Kitasenju Station, and transfer to the Tobu-Sano Line at Tatebayashi Station.

114.Karasawayama Castle Part2

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. Of course, some of the visitors enjoy historical items at the site as well.

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.

Some of the cats living in the shrine

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.

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.
