Please check the availability ahead of time before your visit.

Features

Main Route is partially available

The Main Route to the top is still closed at the middle of the route where it is being repaired as of May 2023. Therefore, you can not go straight through the route, however you can see what it is by walking up the route from the foot to the repaired point and walking down from the top to the point. The route basically goes along another ridge of the mountain and its entrance is on the bottom of a large deep ditch which was surrounded by high vertically cut cliffs on both sides. Today’s visitors can enjoy a great view of the work by the builders, but past enemies must have felt a threat from the defenders. The narrow route continues to go along the ridge on the right, which the defenders would have attacked from in the past and landslides would easily destroy the route from today.

The route goes along the ridge on the right

Above the repairing point, the route turns right and takes over another ridge to reach the Main Enclosure. The point taking over it is another artificially-made narrow ditch, which was another defensive point.

Later History

During the Meiji Restoration, the Satsuma Domain, a relative of the Sadowara Domain, got the power in the domestic politics. The Sadowara Domain joined the activities because the lords of both domains came from the same Shimazu Clan. The last lord of the domain, Tadahiro Shimazu was planning to move his home base to a more convenient land, Hirose. He started to build a new castle there and abolished Sadowara Castle where its buildings were all demolished in 1869. However, the launch of the castle was stopped before the abolition of the feudal domain system by the central government in 1871.

The ruins of Sadowara Castle had been used as fields (probably only in the plain area) for a long time. The excavation of the plain Second Enclosure was done in 1989 and the Main Hall on it was restored in 1993. The excavation of the Main Enclosure on the mountain was also done in 1996. It found that the foundations of the Main Tower Base and some roof tiles with golden leaf which was often used for Main Towers. That resulted in Sadowara Caste being the southernmost castle which had the Main Tower in Japan so far. As a result, the castle ruins were designated as a National Historic Site in 2004.

My Impression

I visited the ruins of Sadowara Castle three times in total. My first visit was several years ago, which I don’t remember very well. The second one was in 2022 just after the closing of both routes to the mountain part due to the natural disaster, which disappointed me. I didn’t know about the news and the vulnerable nature of the mountain on the Shirasu Plateau. I finally reached the top again after hearing the good news of its re-opening. When I was wandering the top around, I found some other parts were still closed and some trees fell beside the road. I realized the difficulty of maintaining the ruins and thought that nature might have even helped the castle prevent enemies from attacking it. Please check if these routes are open if you want to visit the ruins.

Another major enclosure called the South Castle was still closed

How to get There

If you want to visit the castle ruins by car, it is about a 10 minute drive away from Saito IC on the Higashi-Kyushu Expreesway. There is a parking lot in front of the castle ruins.
If you want to use public transportation, you can take the Miyazaki Kotsu Bus bound for Saito Bus Center at Miyazaki Station and get off at the Koryu-Center-mae bus stop.
From Tokyo or Osaka to Miyazaki Station: Take the Miyazaki-kuko Line from Miyazaki Airport after using a plane.

Limited Opening Days and Routes to Top

Today, the ruins of Sadowara Castle consist of two parts, the restored Main Hall in the Second Enclosure at the foot and the remaining foundations on the mountain including the Main Enclosure. The Main Hall is used as a museum called Kakushokan or the Crane and Pine Hall, where you can learn about the history of the castle and see restored or excavated items. However, as of May 2023, please make sure it is basically open only on weekends and public holidays probably for its operational purposes.

In addition, the routes to the mountain part is not always open as well because of occasional damages caused by natural disasters. For example, there are two routes to the top, however, only one route is available as of May 2023. This is because the harsh weather from Typhoon No.14 in 2022 caused landslides to the mountain that made all the routes impossible to be used. Officials have been restoring the routes and just opened one of them back in January 2023. Such a situation has often been happening to the mountain, so the officials even now struggle to maintain the mountain part. That may also have been the reason why the Sadowara Domain closed the part when they built the Main Hall at the foot.

Going on Middle Route to Top

The only open route to the top is called Nakanomichi or the Middle Route, which was considered the back route. The top is only 40m above from the foot, not far from it, however, it is not easy to access, which meant it had a very defensive design in the past. The Middle Route goes on a valley between ridges of the mountain. It is very steep and is unstable on the feet, so if it rains a lot, it could be dangerous. The ridges have enclosures and their sides are cut vertically by processing the soil of the Shirasu plateau. If you were an enemy, you would have been attacked from above of both sides.

Slightly remaining Main Tower Base in Main Enclosure

You will eventually reach a fork in the route at he top area, which surrounds the Main Enclosure. The enclosure also has steep cliffs on its side, which was probably cut vertically by the builders. If you take the route on the right, you will arrive at the back entrance of the enclosure.

While if you take the left one, you will enter the main entrance of it.

The Main Enclosure now looks like two connected squares and the ruins of the Main Tower base is in the back one. The base ruins have only the foundational stones lining up on the ground. Their upper part was probably destroyed intentionally by the lord of the castle when they closed the mountain part. That makes it difficult to find out who and when the base was first built.

The castle symbolized the Ito Clan’s success and failure.

Location and History

Ito Clan from eastern Japan builds Castle

Miyazaki Prefecture is located in the eastern part of the Kyushu Region, which is known for its agriculture. Because of its long from the north to the south and its face is the direction of sunrise, therefore, it’s suitable for farming. Almost all the area of the prefecture was called Hyuga Province, which means the province facing the sun. It is easy to see the province had been fertile since the Ancient Times. There has actually been the popular Saitobaru Burial Mounds which were built between the 4th and 7th Centuries in the central part of the prefecture. The province also had the legend of the first Emperor Jinmu coming from there, going to the east, in order to establish Yamato Imperial Court.

Sadowara Castle was the one which once became the center of Hyuga Province and the home base of the Ito Clan. The clan originated from the Kudo Clan and called themselves a land name of Ito when they settled in Ito, the eastern part of Izu Peninsula, eastern Japan in the 12th Century. Since the Kamakura Shogunate was established at the end of the century, some of the warriors were sent by the shogunate to local areas to govern them. A branch of the Ito Clan, which was sent to Hyuga Province, was one of them. The Tajima-Ito Clan, which was named after the settlement, was said to have first built the castle in the 14th Century.

Meanwhile, another person from the core family of the Ito Clan was also sent by the Ashikaga Shogunate to Hyuga Province in the same century to govern the area during the Northern and Southern Courts period. Both Ito Clans were eventually unified and became a strong warlord based in Sadowara Castle. During the Sengoku Period between the 15th and 16th Centuries, the clan often fought against the Shimazu Clan from the south over Hyuga Province. The lord of the clan at that time, Yoshisuke Ito was so aggressive that he was able to capture Obi Castle, a major one in the southern Hyuga Province in 1569. He was just at his peak, having owned 48 castles in the province, in which Sadowara Castle was at the top. Its castle town prospered like the provincial capital and it was called Little Kyoto in Kyushu.

Sadowara Castle is basically considered one of the Southern Kyushu type castles which were built on the Shirasu Plateau looking like a mountain or a hill in the area. The plateau has been made from volcanic ash caused by ancient eruptions. Its soil is fragile and can easily collapse to form cliffs. Warriors in the area often used this nature to build their castles because it was easy for them to process natural terrain for strong defensive systems. For example, they built deep dry moats, high walls under enclosures, and narrow defensive gates by cutting the soil. Some popular examples of them were Chiran, Obi and Sadowara Castles.

Castle is captured by Shimazu Clan due to Collapse of Ito

Yoshisuke Ito’s glory didn’t last long, however. He was losing the Ito 48 Castles one by one, triggered by the lost of the Battle of Kizakihara against the Shimazu Clan in 1573. The Shimazu’s force and the Ito’s deterioration also made his retainers alienate him more and more. He wondered if he could be besieged in Sadowara Castle, but the situation didn’t allow him to do so, but he was forced to leave the castle. He escaped from Hyuga Province with his family and few vassals to Bungo Province in the north, where his ally, Sorin Otomo governed. This was called the Collapse of Ito. They had finally lost all that they had and eventually became wanderers. Yoshisuke died while drifting in 1585 before his son, Suketake returned to Obi Castle in Hyuga Province in 1588 by serving his new master, the ruler, Hideyoshi Toyotomi.

Sadowara Castle was eventually owned by the Shimazu Clan. The clan might have improved the castle by building the Main Tower on the top, but It has not been confirmed yet. The Main Tower is said to be the one which was located in the southernmost place in Japan. After the lord of the castle, Toyohisa Shimazu was killed in the battle of Sekigahara in 1600, the castle was followed by the Tokugawa Shogunate and Mochihisa Shimazu whose successors governed it until the end of the Edo Period as the Sadowara Domain. Mochihisa’s son, Tadaoki abandoned the castle on the mountain and moved it to the foot where the Main Hall was built. This was because maintaining the castle on the Shirasu Plateau was too difficult and the hall on the plain land was convenient for the government during the peaceful Edo Period.
