96.Obi Castle Part3

The completed castle on the Shirasu plateau

Features

Samurai Residence street and Domain school

If you walk around the eastern part of the main portion, there is the Samurai Residence street which still has its original atmosphere with stone walls, white mud walls, hedges and traditional gates. Though many of the residential buildings inside were turned into modern facilities, restaurants or residences, some of them remain as they were, for example, a former senior vassal, Ito’s residence being used as a hotel.

There is also the restored domain school building, called Shintoku Hall, one block north from the street, which provided talented people, including Jutaro Komura who was the plenary power of the Japanese side to sign the Treaty of Portsmouth to end the Russo-Japanese War in 1905. The stone walls around it are original, so when they needed to be re-piled for repairing, all stones should be numbered and re-piled to the original positions exactly as historical items.

Walking on former Castle Town

Visiting the former castle town below the castle ruins is also recommended, which is surrounded by the winding Sakatanigawa River. The town also has a similar atmosphere to the Samurai Residence street and looks more casual. For example, Ushiromahi or the Back Town street has waterways with varicolored carps swimming. Honmachi-Shonin (or the Main Town Merchant street) has old merchant houses where you can enjoy eating and shopping.

Finally, if you look at the castle ruins from the western side of the town along the river, you can see the castle was built on the edge of high and vertical cliffs which originate from the Shirasu plateau. Part of the cliffs are covered with concrete to avoid them from collapsing. Modern-day people are still struggling to maintain the castle ruins on the cliff, so the Obi Domain by the Ito Clan must have made much greater efforts to do it.

Later History

After the Meiji Restoration, most of the castle buildings were demolished. However, the layout of the castle and town including their street plans continued being used to the present time. Nichinan City launched the restoration project in 1974. After that, the area of castle ruins and town were designated as the first Preservation District for Groups of Historic Buildings in the Kyushu Region in 1977, followed by the restoration of the Main Gate in 1978 and the hall in Matsu-no-maru Enclosure in 1979. That’s why we can enjoy the well-balanced remaining and restored items in this site.

The castle town also has great stone walls

My Impression

I think Obi Castle is the completed castle on the Shirasu plateau. Building castles on the plateau was easy thanks to its nature, while maintaining them could be very difficult. Natural hazards, such as harsh weathers and earthquakes, often caused collapsing of cliffs in these castles. Because of that, other castles of the same type like Sadowara, Shibushi, Chiran were abandoned in the peaceful Edo Period. However, the Ito Clan, the lord of the castle, didn’t have any substitute land. That’s why the clan’s Obi Domain continued to build their castle and town all through the period which we can enjoy to visit right now.

How to get There

If you want to visit the castle ruins by car, it is about a 45 minute drive (through Miyazaki Prefectural Road 28) away from Tano IC on the Miyazaki Expressway. There is a parking lot for visitors in front of the castle ruins.
If you want to use public transportation, it takes about 15 minutes on foot to get there form JR Obi Station.
For visitors from Tokyo or Osaka: It may be a good idea to rent a car at Kagoshima or Miyazaki Airports after using a plane.

That’s all. Thank you.

96.Obi Castle Part1

The castle the Ito Clan managed to maintain

Location and History

Shimazu Clan first owns Castle

The Obi area of Nichinan City, in the southern part of Miyazaki Prefecture, is popular for tourism. It is sometimes called a little Kyoto in the Kyushu Region. It has an old atmosphere of castle and town, which has been designated as a Preservation District for Groups of Historic Buildings since 1950. It also provides its local specialties such as Obi cedar trees and a traditional Japanese spirit, Shochu, made from sweet potatoes. In fact, they originally came from the long and severe history of Obi Castle and the Obi Domain.

It is said that a local clan first built Obi castle in the 14th Century, but its details are uncertain. During the Sengoku Period, from the late 15th Century to the end of the 16th Century, the southern part of Hyuga Province (currently Miyazaki Pref.) became the site of the battle over the province between the Ito Clan from the north and the Shimazu Clan from the south. The Shimazu Clan owned the area at that time, so they improved Obi Castle in 1458 to prevent the area from being invaded by the Ito Clan.

One of Southern Kyushu type castles

The castle was originally one of the Southern Kyushu type castles. They were built processing the natural Shirasu plateau, which was made of volcanic ash caused by ancient eruptions. Its soil is fragile and can be easily collapsed vertically to make cliffs. Warriors in the area often used this geographical feature to build their castles, because it was easy for them to process the 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 those were the Chiran, Shibushi, Sadowara and Obi Castles. In addition, in the case of Obi Castle, Sakatanigawa River winded and surrounded the plateau as a natural moat.

Ito Clan’s success and failure

The Ito Clan started to attack the Obi Castle in 1484, before the long battle over the castle. The lord of the clan in the middle of the 16th Century, Yoshisuke Ito was so aggressive that he was able to capture the castle and send his son, Suketake to it as its lord in 1569. He was just at his peak, having owned 48 castles in the Hyuga province. However, his glory didn’t last long, he was losing the 48 Castles one by one including Obi Castle, triggered by the defeat at the Battle of Kizakihara against the Shimazu Clan in 1573. The Shimazu’s force made the Ito family flee from the Hyuga Province to the Bungo Province in the north in 1577, which was called the Collapse of Ito. They finally lost all that they once had and eventually became wanderers. Yoshisuke died while drifting in 1585.

Ito Clan returns and governs Castle long

After this misfortune, Yoshisuke’s son, Suketake was occasionally hired by Hideyoshi Hashiba, who would be the ruler, Hideyoshi Toyotomi later in 1582, who was very fortunate for Suketake. When Hideyoshi invaded the Kyushu Region, which was almost completely controlled by the Shimazu Clan in 1586, Suketake supported Hideyoshi to guide the region. The Shimazu Clan eventually surrendered to Hideyoshi. Suketake finally returned to Obi Castle as its lord in 1588 due to his contribution to Hideyoshi after over 100 years of battle with the Shimazu Clan.

The Ito Clan somehow managed to maintain their territory of the Obi area while the ruler of Japan changed from the Toyotomi Clan to the Tokugawa Shogunate. As a result, the Obi Domain led by the Ito Clan, continued to exist until the end of the Edo Period for nearly 300 years. However, it was not that simple. The Satsuma Domain led by the Shimazu Clan secretly sent Ninja to Obi to research what Obi Castle was like. They still seemed to want to take the castle away from the Ito Clan, if the situation changed. Meanwhile, the Ito Clan also seemed to recognize Obi as their final ground, improving the castle and town the hard way. For instance, the Main Enclosure on the top collapsed due to earthquakes in the late 17th Century because the plateau under it was weak. The Obi Domain rebuilt the new Main Enclosure below the former one and fortified both of them by building great stone walls. It also introduced planting cedar trees and sweet potatoes for people and industrialization to be sustainable.

197.Shibushi Castle part1

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.

The relief map around the castle

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.
