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.

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.

Wonderful molding using natural terrain

Features

Nakanokuo, Pivot of Defense

Over the dry moat, the other major enclosures of Nakanokuo (the enclosure No.4 & 5) and Onokuo (the enclosure No.6 & 15) follow and are all divided by other dry moats crosswise. In particular, you should check out Nakanokuo (the enclosure No.5), over Nakanokuo (the enclosure No.4). To reach the enclosure, you need to go out of the Main Enclosure, go through the right lengthwise dry moat from the front, and enter the second crosswise dry moat. The bottom of the moat is not flat, but has two tiers, so you also need to climb to the upper tier.

The map around Uchijo portion, the red broken line is the route from the Main Enclosure to Nakaokuo (the enclosure No.5)

The second crosswise dry moat has two tiers

Then, you will face huge vertically cut cliff of the enclosure like a thick column and need to walk around to enter. If you were an enemy, you must have been attacked by the defenders from above until then. The entrance path is altered by thick earthen walls as well, just like a palace gate made of soil. This enclosure might have been pivotal to the defense in the castle.

Amazing Dry Moats

Both the lengthwise dry moats outside the plateau are amazing. The dry moat on the left side from the front (the western side) is called O-Horikiri or the Large Ditch. It is about 17m deep and was about 7m deeper than now according to the excavation. The collapsing volcanic ash has been filling the bottom of the moat naturally. However, it is still enough for us to understand how great the warrior’s work for the moat was.

The dry moat on the right side is also surprising. The cut section of the outside enclosure is still vivid making us understand how hard their work was!

The Back Route of the castle goes beside the cut section and very narrow like the Main Route. It must have been made very defensive like the Main Route.

Later History

After Shibushi Castle was abandoned, the foot of the mountain was used as the warriors’ residences called Shibushi Fumoto. Fumoto refers to a residence area for a unique defense system of the Satsuma Domain led by the Shimazu Clan, called Tojo or the Outer Castles, during the Edo Period. Unlike other domains letting their retainers live together in their home base, the Satsuma Domain sent many of its retainers to their local sites to protect the frontiers of its territory. Shibushi Fumoto was one of the most important among over 100 Fumoto of the domain. You can also walk around the Fumoto area at the same time as visiting Shibushi Castle Ruins. As for the castle ruins, they have been excavated and researched since 2003. As a result, they were designated as a National Historic Site in 2005.

The area around still has an atmosphere of Shibushi Fumoto

My Impression

I have never seen such a large and precise miniature model of a mountain castle like the one of Shibushi Castle (Uchijo portion) in Shibushi City Center for Archaeological operations before. I have certainly seen large and precise miniature models of more modern castles like Himeji Castle because they often had or still have many buildings such as the Main Tower, turrets and gates, and great structures such as stone walls. They would be easy to be copied for a model and the model can be popular with people. On the other hand, making models of a mountain castle should be difficult and may be less popular, so it could be rare, especially realistic ones. However, the miniature model of Shubushi Castle is one of the rarely seen models, worth to see by itself, and helps visitors understand what the real castle was very well.

How to get There

If you want to visit the castle ruins by car, it is about a 15 minute drive away from Shibushi IC on the Miyakonojo-Shibushi Road. There is a parking lot for visitors near the ruins. In addition, Shibushi City Center for Archaeological operations is about 3km away from the ruins and it also has a parking lot.
If you want to use public transportation, it takes about 20 minutes on foot to get there form JR Shibushi 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.
