Today, the ruins of Takaoka Castle has become the Takaoka Old Castle Park which is open to the public. The park looks like part of the water moats rather than being surrounded of them. This is because almost all of the foundation and the water moats for the castle remained until now. In fact, the water moats occupy about one thirds of the park. It is really a natural park now as you can try going on a boat tour on the moat.
There are five enclosures such as the Main Enclosure among the moats. Each enclosure is independent and they are connected each other by only earthen walls or bridges. In particular, the Main Enclosure was accessible only through other enclosures, can not be accessible directly from the outside in the past.

Main Enclosure like Hill
The Main Enclosure is the largest one and like a hill, so you have to climb up to the center of it. The enclosure has the Imizu Shrine and a square with the statue of Toshinaga Maeda standing beside it.
It was found through the excavation that the Main Hall for Toshinaga was built in the enclosure. It is uncertain about other buildings in the castle because the castle was abandoned before their completion. Only the stone walls remained at the one side of the enclosure, which may be the only castle-looking item.
Other Enclosures for Modern facilities
Other enclosures are also used for modern facilities, the Second Enclosure for the Civic Hall, the Kaji-maru Enclosure for the City Museum, the Aki-maru Enclosure for a zoo, and the Minbu-maru Enclosure for a zym.
The whole park is also very known for cherry blossoms that surrounds it, they bloom around spring. The citizens in Takaoka City are very familiar with this park and recognize Toshinaga as the founder of the city.
The main portion of the castle is still outstanding.
Features
From Parking lot to Main portion of Castle
Today, you can access the main portion of the ruins of Nanao Castle directly by car. The ruins, however, don’t have castle buildings now, but their foundation remains intact. There is a parking lot on one of the enclosures under the Cho Residence. You can walk on the well developed trail to the Main Enclosure from the parking lot.
The map around the castle
You can also see the large deep ditch called Horikiri between the Main Enclosure and the Cho Residence followed by the vertically cut cliff called Kirigishi of the Main Enclosure along the trail. They are, however, artificial.
You will first reach the Chodo-maru which was the place where weapons were prepared under the Sakura Riding Ground. The original Main Route also reached the Chodo-maru in the past.
Wonderful stone walls
Next, you will see the large five-tier stone walls piled up naturally called Nozura-zumi when you walk up to the Sakura Riding Ground. The stone walls look beautiful because of the moss that covers it. They were built by Toshiie Maeda and are one of the highlights of the castle.
From the front of the Sakura Riding Ground, you can go straight to the Main Enclosure through the Yusa Residence. However, this route was not original. It was said to have been built when the Shiroyama Shrine was established on the enclosure about 80 years ago. Thanks to that, you can also see the great three-tier stone walls of the enclosure which is close by.
Main Enclosure was well protected
The enclosure was protected well by the stone walls and the vertically cut cliff in the past. The original route zigzagged and went around the back of the enclosure, guarded by the other square space called Soto-Masugata which was put on the outside of the enclosure.
The inside of the Main Enclosure is basically empty and the monument of the castle remains standing. The shrine is on the ruins of the Main Tower. The tower is thought to have a cypress bark roof or shingled roof, because no roof tiles were ever found during the excavation. The view from the enclosure is amazing. If the weather is nice, you will be able to see the whole view of Nanao City along the Nanao Bay and Noto Peninsula.
Nanao Castle was a large mountain castle located in Noto Province, what is now the modern part of the northern Ishikawa Prefecture, the Hokuriku Region. The castle was built on about 300m high mountain ridges and the name “Nanao” originates from the number of the ridges which is seven. The Hatakeyama Clan was a relative of the Ashikaga Shogunate in the Middle Ages. One of the groups of the Hatakeyama Clan was sent to Noto Province as the governor of the province in 1408. Since then, the clan developed Nanao Castle. The castle became the capital of the province with the castle town prospering at the foot of the mountain. A great painter by the name of Tohaku Hasegawa came from this town in the middle 16th Century. He left a portrait of a warlord which was said to be that of famous Shingen Takeda from its impression, but it is now said to be one of the lords of the Hatakeyama Clan.

Hatakeyama Clan governed it with senior vassals
The Hatakeyama Clan governed Noto Province and Nanao Castle for about 170 years together with their senior vassals such as the Yusa Clan, the Cho Clan and the Nukui Clan. They often cooperated with each other to defend attacks from the invaders, but they often had to deal with internal conflicts. It was both a strength and weakness for them. The structure of the castle also reflected the formation of the lord and the senior vassals. The main portion of the castle was on the highest one of the seven ridges called Matsuo-yama. There you will be able to see the Main Enclosure on the top, the Yusa Residence, the Sakura Riding Ground, the Nukui Residence, and the Second Enclosure in line with the ridge. The Cho Residence and the Third Enclosure were on the both sides of the main portion divided by the large deep ditches. As shown in the names of the enclosures, the senior vassals had their own enclosures for their residences, which showed the balance of their power.
Uesugi and Oda Clans battled over Castle
Around Noto Province in the late 16th Century, the two great warlords were dominating, Nobunaga Oda in the west of the Province and Kenshin Uesugi in the east. Kenshin decided to attack Nanao Castle in 1576 despite the lord of the castle being a child who was supported by the senior vassals. Kenshin was said to be the strongest warlord, and he only needed to siege the castle without the need for an aggressive attack. The siege lasted for about two months, and the young lord was unfortunately killed by the epidemic. The senior vassals had different opinions. On one side, the Cho Clan wanted to ask Nobunaga for help, however, the Yusa Clan did not feel the same way. Nobunaga finally sent his reinforcement to the castle, and the Yusa Clan managed to defeat the Cho Clan and supported Kenshin. Eventually, the castle finally belonged to Kenshin.
Despite the victory, Kenshin died just six months later, and as a result, Nanao Castle was eventually occupied by Nobunaga. Nobunaga gave Noto Province and Nanao Castle to his retainer, Toshiie Maeda in 1581. Toshiie built the Three-layer Main Tower on the Main Enclosure and large scale stone walls which was the front side of the castle. On the other hand, Toshiie also built his new home base called Ko-Maruyama Castle near Nanao Port for the convenience of the government and ease of transportation. Nevertheless, the reason why he continued to improve Nanao Castle was thought to be for the new Main Tower. Furthermore, the stone walls showed his authority and it symbolized the lord of the castle has changed in that area. The castle was eventually abandoned in 1589.
