The warriors maintained the castle for a long time.

Features

Umaarai Rock, Second Enclosure and Photo spot

The map around the castle

If you climb down from the top on another route, you can see the biggest rock around, called Umaarai-iwa, just below the Main Tower base, whose perimeter is about 45m. It should make you feel power of nature.

The Second Enclosure is far below from the top, where the Main Hall for the lord was in the past. The hall was built hanging out from the enclosure by also using the Kake-zukuri method.

In addition, if you want to take in a great whole view of the ruins, you can take another return route to the photo spot.

Later History

After the Meiji Restoration, Naegi Castle was abandoned and all the buildings of the castle were demolished. The mountain the castle was located on was returning to nature, being covered with trees. However, the ruins of Naegi Castle were designated as a National Historic Site in 1981 because the foundation of the castle ,including its stone walls, remained intact. The ruins recently became popular due to their unique features, such as the combination of natural rocks and stone walls, and great views. Some trees were cut down to see the main portion of the ruins clearly for visitors.

My Impression

It is said that there were six types of stone walls in Naegi Castle, ranging from the oldest one using natural stones to newer advanced ones. That meant the Naegi Domain continued to build or repair them under the severe living condition for over 250 years in the peaceful Edo Period. I was very impressed by that.

The stone walls piled in a way called Tani-zumi or the Form of a Vally, near the entrance of the ruins
The stone walls piled in a way called Uchikomi-hagi like piling roughly processed stones, at the Northern Gate Ruins, in the back of the Large Turret Ruins
The stone walls piled in a way called Kirikomi-hagi like piling precisely processed stones, at the Large Turret Ruins
The stone walls piled in a way called Nozura-zumi like piling natural stones, around the starting point to the top

I remember an example of a similar case to Naegi Castle, called Oka Castle in the Kyushu Region. The castle was likewise built on a rocky mountain. It was very defensive but hard to live in, so the warriors immediately disappeared after the Meiji Restoration.

How to get There

I recommend using a car when you visit the castle ruins.
It is about a 10-minute drive away from Nakatsugawa IC on the Chuo Expressway. There are several parking lots around the ruins.
If you want to use public transportation, you can take the Kita-Ena-Kotsu Bus bound for Tsukechikyo-Kuraya-Onsen or Kashimo-Sogo-jimusho from Nakatsugawa Station and get off at the Naegi bus stop. It takes about 20 minutes on foot from the bus stop to get there.
To get to Nakatsugawa Station from Tokyo or Osaka: Take the Tokaido Shinkansen super express and transfer to the Chuo Line at Nagoya Station.

The castle ruins integrate stone walls and natural rocks.

Features

Going to Center from Entrance

Today, no castle buildings remain in the ruins of Naegi Castle, but you can still see the spectacular foundation mixing stone walls and natural rocks. Just after you enter the entrance of the ruins, you can see a great expansive view of the top of the mountain with the observation platform from the ruins of the soldiers’ barracks.

Then, if you walk to the center of the ruins along the mixed walls of natural rocks and stones, you will reach the Third Enclosure. This enclosure had originally been a deep dry moat for defense but was eventually filled to make more land for buildings later.

Large Turret Ruins, and going to Top of Mountain

There are the ruins of the Large Turret in the front, which is the remaining base of huge rocks and stone walls. You can climb up to the top of the base to see the top of the mountain closer.

To climb up to the top of the mountain, you will need to walk on a narrow and zigzagging route alongside the rocky terrain. You will also see a lot of ruins of gates and buildings as you go. That means those buildings were crowded in such a small space in the past.

You will finally arrive at the Main Enclosure on the top. It is now empty, but you may feel it’s not large. There were also some buildings such as the living quarters for the lord.

Observation Platform, no less than real Main Tower

The base for the Main Tower is a huge rock itself on the top and the observation platform is on it instead of the historical tower. The platform was built using the method of Kake-zukuri like the original tower. The columns of it use the same post holes on the rock as the tower, so you can easily imagine how great it was.

Moreover, the deck of the platform has the same size and level as the top floor of the original tower. You can enjoy the same great view of the area around, including the Kiso River, Nakatsugawa city and the mountains behind, just as the lord did back then.

Location and History

Castle monitoring Nakasendo Road

The Nakasendo Road is known for being one of the major roads in Japan and was designated as one of the Five Major Roads in the Edo Period. In particular, the road was the most useful one when large amount of troops moved between western and eastern Japan before the period. The area of what is now Nakatsugawa City in the eastern part of Gifu Prefecture had Nakatsugawa Post Town in a basin at the center with the road going to mountain areas in the east. That’s why the warlords in the Sengoku Period wanted to own the area to monitor this important spot on the road. Naegi Castle was built on Takamori Mountain beside Kiso River which was sandwiched by the castle and the town. That meant the castle was the most suitable for monitoring what happened on Nakasendo Road.

Toyama Clan builds and somehow maintains Castle till end

In the 16th Century during the Sengoku Period, The Toyama Clan was one of the local warlord families in the area, which was called the eastern Mino Province. It is said that the clan first built the castle in the first part of the16th Century as a branch castle of their home base, Iwamura Castle. However, the clan was affected by other larger warlords such as the Takeda and Oda Clans which also wanted to own the area. For example, both the Takeda and Oda Clans battled each other between 1572 and 1582, gaining and losing this castle.

After the declines of both, the Mori Clan, under the ruler Hideyoshi Toyotomi captured the castle. Tomomasa Toyama, with his father Tomotada, the lord of the castle at that time, had to escape from the castle to Ieyasu Tokugawa at Hamamatsu Castle. In 1600 when the Battle of Sekigawara occurred, Tomomasa succeeded in getting Naegi Castle back with Ieyasu’s approval. After Ieyasu established the Tokugawa Shogunate, the Toyama Clan governed the castle again as the Naegi Domain until the end of the Edo Period.

Castle on Rocky Mountain, Main Tower on Huge Rock

Naegi Castle had a very special location as far as permanent castles in Japan go. The mountain the castle is located on has a rocky terrain and steep cliffs. It was good for the defenders to make very difficult to attack, but if the lord of the castle wanted to develop it, there would be few spaces to do so. Generally, buildings or inter routes of castles were built on stone walls surrounding natural terrain or stone wall bases at that time. However, in the case of Naegi Castle, it was difficult to cut the rocky surface for buildings or routes. As a result, they were built on bases mixed with natural rocks and stone walls or filled valleys. Even if more buildings were needed, they were built on natural rocks directly. For example, the Main Tower of the castle was built on the huge rock on the top of the mountain.

Traditionally, when Japanese people wanted to build a building on natural rocks, they used a method called Kake-zukuri. The method is to build the foundation by combining many columns and horizontal beams like lattices on a steep rock or cliff. Buildings using this method have still been seen in some old shrines and temples like Kiyomizu-dera Temple in Kyoto. It is said the reason for using this method is that the mountains themselves, which have the rocks or cliffs, are the objects of worship. When many castles were built during the Sengoku and the first part of the Edo Period, the method was applied to castles. Naegi Castle is a good example, and another case in Sendai Castle is known.

The Naegi Domain earned only 10 thousand koku of rice which was a minimum amount for an independent lord. Because of this, their castle buildings had wood shingle roofing and wood siding or mud walls, not roof tiles and plaster walls which were too expensive for them. However, they built and maintained these buildings under such severe conditions even during the long lasting peace of the Edo Period. This was because staying there to be ready for any emergency was their most important duty.
