The castle ruins integrate stone walls and natural rocks.

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.
You can see how the castle was developed at the site.

Older part of Castle
Today, the ruins of Minowa Castle have been well developed for visitors. If you have a car, you can park at some parking lots for the visitors beside the ruins. The main parking lot is the eastern foot of the hill where the castle was located. You can walk up from the parking lot to the ruins on a gentle winding slope which was actually the Back Route. You will first reach the Second Enclosure, part of the main portion of the castle.
The map around the castle
The main portion consists of the Second, Main and Gozen Enclosures from south to north. These enclosures are basically surrounded by thick earthen walls and divided by deep dry moats, which are the oldest part of the castle. If you walk into the Main Enclosure where the hall of the lord was built, you can now see the recently restored wooden bridge connecting to the western part of the castle.
If you go further, you will reach the Gozen Enclosure, the last part of the Nagano Clan. There is the well in the enclosure, which was discovered in 1927, where many memorial tablets of the clan were found from the bottom. That meant the episode when the clan had been defeated may have been confirmed.
Vast Dry Moat
You can walk down the steep trail on the northern edge of the Gozen Enclosure to the bottom of the dry moat. If you turn right to the east, you will reach the Inari Enclosure that Naomasa Ii built. This enclosure had a water moat on the side in the past.
If you turn left to the west, you can walk around the bottom and see how large and deep the moat is. You can also see the older stone walls surrounding the Gozen Enclosure, which the Nagano Clan might have built. If you go further to the south, you will arrive at the Second Enclosure.
Umadashi System is developed later
The Second Enclosure was the pivot of offence and defense, where the three main routes to the castle are all together. Other than the Back Route from the east, the Main Route comes from the west and the other route comes from the south. In particular, a great artificial trench called O-Horikiri is dug in the southern side of the enclosure to prevent enemies’ attacks.
Only the narrow earthen bridge is over the trench, connecting to the southern route. Moreover, a square stronghold called Kaku-Umadashi is sticking out of the Second Enclosure through the bridge. The Umadasi system is a unique defense system which the Takeda and Tokugawa Clans often used. This system in Minowa Castle was probably developed by Takeda and completed by Naomasa under Tokugawa. The two-story turret gate called Kaku-umadashi Western Entrance Gate was recently restored based on the achievement of the excavation, which had been the symbol of the castle.
Endo Clan first builds it as Stronghold for battle
Gujo-Hachiman town is well known for its attractions such as an old street atmosphere, the beauties of nature, and the Gujo Odori Dance Festival in the summer. It was originally the castle town of Gujo-Hachiman Castle which was first built on Ushikubi-yama Mountain back in 1559. At that time during the Sengoku Period, almost all the people in Japan had to protect themselves and govern their communities all by themselves. In a small region called Gujo District in the northern mountain part of Mino Province, which is now the modern day Gujo City in Gifu Prefecture, the Endo and Tou Clans battled each other over the district. Eventually, the Endo Clan would win and their stronghold for the battle directly became Gujo-Hchiman Castle. The name “Hachiman” originates from a shrine’s name which the clan established at the foot of the mountain. The castle was said to be a simple mountain castle made of soil.
The location of Gujo-Hachiman Castle
Yoshitaka Endo, the lord of the castle in the late 16th Century, had to work under other greater warlords in the Chubu Region, such as the Saito Clan and the Oda Clan. This was because lords of small regions did not power, therefore, needed to be guaranteed by great warlords in order to maintain their territories. On the other hand, they also needed to find out the next leader whom they would be working under. In the case of Yoshitaka, he supported Nobutaka Oda in Gifu Castle, who fought against Hideyoshi Toyotomi and was defeated in 1583. Unfortunately, he made a bad choice and surrendered to Hideyoshi. He was once overlooked, however he was eventually transferred from the lord of Gujo-Hachiman Castle to a much smaller territory by Hideyoshi in 1588.
Inaba Clan’s Modernization and Endo Clan’s revenge
After that, Sadamichi Inaba became the lord of the Gujo-Hachiman Castle and started to renovate and modernize the castle by building stone walls around the Main Enclosure on the top of the mountain. The enclosure had the stone wall base for a Main Tower on it, but it was uncertain weather or not the Main Tower was built. It was also surrounded by the Belt Enclosures with tripled stone walls. Moreover, the back of the Main Enclosure which was the part connecting to other mountains was separated by doubled deep ditches. Gujo-Hachiman Castle became a strong castle protected not only by natural terrain but also by the advanced structures.
On the other hand, Yoshitaka Endo was waiting to recover. The chance to recover came in 1600 when the battle of Sekigahara would take place. He found out that Sadamichi Inaba supported the Western squad, therfore, he decided to join the Eastern squad led by Ieyasu Tokugawa. He began attacking Gujo-Hachiman Castle after Ieyasu’s approval in advance of Sekigahara. Both troops by Yoshitaka and Sadamichi fought a hard battle, especially in the back of the Main Enclosure. The castle survived most lilely because it got much stronger than Yoshitaka underestimated the strength of the castle. However, Yoshitaka eventually got the castle back in the end as the Eastern squad was victorious in the Battle of Sekigahara. Yoshitaka became the founder of the Gujo Domain under the Tokugawa Shogunate.
Gujo uprising before Government by Aoyama Clan
A big incident happened in the Gujo Domain, which was called the Gujo uprising, in 1758 when the Kanamori Clan governed following the Endo and Inoue Clans. Yorikane Kanamori was the lord of the domain and had an important role for the shogunate which cost a lot of money. Unfortunatelly, his domain was relatively small and had lower income than what he needed. Therefore, he decided to raise the tax rate by changing how to estimate the amount of harvested rice with the cooperation from some high class officers of the shogunate. This made farmers in the domain very angry, together in the rice warehouse at the foot of the mountain. They submitted a petition asking not to raise the tax. However, the domain refused this petition. So then the farmers brought this action in the lord in Edo, a member of shogun’s council of elders, and finally the shogun itself. This incident resulted in many farmers being executed, some shogunate officers were also displaced, and the Kanamori Clan were fired from the lord of the Gujo Domain.
The Aoyama Clan followed the lord of the domain caring for farmers so that another incident would not happen. The clan also allowed people to dance in the town freely, which was said to be the origin of the Gujo Odori Dance Festival. As for the Gujo-Hachiman Castle, the clan moved the center of the castle from the top of the mountain to the Second Enclosure at the foot, where the Main Hall was. This was a typical way for the lords in the Edo Period to govern their domain in the peaceful time. As a result, the Second Enclosure was turned into the Main Enclosure. The former Main Enclosure was then divided into the Cherry Enclosure and the Pine Enclosure.
