A castle on the Shirasu Plateau, built near an important port

Location and History

Shibushi has been Important Port

Shibushi City, which is located in the eastern part of Kagoshima Prefecture, may have kind of a unique name even in Japanese. This is because when you say the city’s name in Japanese, you will say “SHI-BU-SHI-SHI(city)” which may be difficult to pronounce. This phrase is sometimes used as an example of a Japanese tongue twister like “Shibushi-shi, Shibushi-cho, Shibushi, no, Shibushi-shiyakusho, no, Shibushi-shisho” which means “The Shibushi branch office of the Shibushi city hall, Shibushi, Shibushi Town, Shibushi City”. If you want to understand why it’s called “Shibushi”, you can find it refers to “Present, Cloth and Present” in Japanese. It is said to originate from the legend of the ancient Emperor Tenchi visiting. He was presented cloths from both upper-class and lower-class people, he was very pleased and came up with the name. We are uncertain if the legends are true but the land does have a long history.

Another feature of the city is Shibushi Port which is designated as a Major Port and a Core International Port. If you go around the port area, you can see huge amount of containers and wood, and some ferries such as Sunflower. The port has actually been prospering since the end of the Ancient Times when some manors in the southern Kyushu Region were developed. International trading was also done during the Middle Ages, which made lords around the area rich. That’s why they wanted to possess the area and they often battled each other over it. Shibushi Castle was a mountain castle for the base to govern the area.

One of Southern Kyushu type Castles

Shibushi Castle also had an important feature as one of the Southern Kyushu type castles which were built on the Shirasu Plateau looking like a mountain or 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 to build their castles because it was easy for them to process natural terrain for strong defensive systems such as deep moats and high walls. Some popular examples of that type castles were Chiran, Sadowara, Obi and Shibushi.

For example, if you are in Shibushi Port and look back at the inland area, you will see the long lying cliffs set back from the coastline. The lords in Shibushi built their castles one by one using that natural terrain. In fact, Shibushi Castle is the generic name of four local castles, Uchijo, Matsuojo, Takajo, and Shinjo. It is said that the Nirei Clan first built Matsuojo in the 14th Century, followed by Uchijo, used as the Hatakeyama and the Niro Clan’s home base in the 16th Century. By then, Takajo and Shinjo were also built as outer compounds for the other two castles. The lord of Shibushi Castle changed again and again to the Kimotsuki Clan and finally the Shimazu Clan. This was because the area around the castle was attractive so it became a battle field between great warlords, the Ito Clan in the north and the Shimazu Clan in the south. Some lords of the castle changed loyalty between the two great lords.

Strong Defense system using Shirasu Plateau

At the peak of the castle, the main Uchijo had a very complex defensive system. The original Shirasu plateau was cut by three dry moat lines lengthwise and five dry moat lines crosswise. The remaining parts of the plateau became enclosures independently, surrounded by earthen walls and fences. These enclosures had turrets, barracks and residences to maintain and protect the castle. If visitors or enemies wanted to enter the enclosures, they needed to go from the bottom of the moat and pass the defensive gateway of the enclosure. Enemies at the bottom would be attacked from far above by defenders at the enclosures.

The lords of the castle usually lived in the residence at the foot and used the castle in the cases of emergency such as a battle. However, the excavation team found in the castle ruins, expensive trading items from overseas such as Ceramic ware as well as daily necessities like domestic pottery, coins, and bullets. These items show that the castle was used for a long time and involved with Shibushi Port where the international trading was done. The castle was finally abandoned by the last owner, the Shimazu Clan due to the Law of One Castle per Province, issued by the Tokugawa Shogunate in 1615.

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.

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.

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.

Features

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.

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.
