Mt. Fuji – 日本200名城バイリンガル (Japan's top 200 castles and ruins)

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.

The stone walls seen from the second enclosure side

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 second enclosure in the front and the main enclosure in the back

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.

That’s all. Thank you.

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 original path around the Main Enclosure

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 ditch between the Western and Babadaira Enclosures

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.

125.Kozukue Castle Part3

The ruins have become popular since the construction of the road.

Features

Parted Barbican

In fact, the ruins were partly destroyed and divided by the Daisan-Keihin Road. You can look at one of the barbicans over the road from the entrance of the Western Enclosure. You will have to go through the tunnel under the road to get there. The top of it is one of Fujizuka Mounds, called Fuji-sengen, made for worshiping Mt. Fuji since the Edo Period. It might had been a turret base before that. When you walk out of the ruins, you will get back to the city area right away.

Later History

After Kozukue Castle was abandoned, the local people have called the ruins Shiroyama or the Castle Mountain. The studies about the castle started as early as in the Edo Period. However, the ruins ironically became popular as a historic site since they were partly destroyed by the construction of the Daisan-keihin Road in 1963. Through that, Yokohama City launched the Kozukue Castle Ruins Forest to preserve them in 1977. People are now interested in what the castle was like in the past.

My Impression

I think Kozukue Castle is a good example of how to protect a castle with few defenders. I guess if a battle happened at Kozukue Castle when Hideyoshi invaded, this castle could survive at least over one night unlike Yamanaka Castle and Hachioji Castle.

How to get There

I recommend using a train when you visit the ruins because the park has no parking lot.
It takes about 15 minutes on foot from JR Kozukue Station on the Yokohama Line.

The castle ruins seen from the platform of Kozukue Station

The Yokohama-Kamiasao Road (Kanagawa Prefectural Road 12) goes near the station, so turn right at the Kozukue Station Intersection and go along the street. Then, turn right at the Kozukuetsuji Intersection.

Turn right at the Kozukuetsuji Intersection

Go along the street again, cross the railway and turn left at the first intersection.

Go along the street in the residential area, and when you find the signpost for the ruins on the utility pole on the right, turn right. You will eventually arrive at the entrance of the ruins.
