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.

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.

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.

195.Nobeoka Castle Part1

A castle all built using stone walls by Mototane Takahashi

Location and History

Only Castle completely built using Stone Walls in Hyuga Province

Nobeoka is an industrial city, located in the northern part of Miyazaki Prefecture which used to be called Hyuga Province. The province was very long from the north to the south and its terrain was complex with plain and mountain areas, so it was divided by many lesser lords until the end of the Edo Period, except for a short period when the Ito Clan prospered in the late 17th Century. These lesser lords lived in castles mainly built using soil from the natural terrain, such as Sadowara and Obi Castles. However, Nobeoka Castle was the only castle which was completely built using stone walls in the province by Mototane Takahashi.

Talented Mototane Takahashi

Mototane originally came from the Akizuki Clan, which governed part of Chikuzen Province, north of Hyuga, and he was adopted by the Takahashi Clan. When the ruler, Hideyoshi Toyotomi, invaded the Kyushu Region in 1587 for his unification of Japan, Mototane and his parents’ clan quickly surrendered and supported Hideyoshi. Mototane was loved by Hideyoshi, which resulted in him becoming the lord of the Nobeoka area after Hideyoshi’s conquest of the region. Motonane must have made an good impression on his boss.

In 1600, after Hideyoshi died, the East Squad, led by Ieyasu Tokugawa and the West Squad, led by Mitsunari Ishida, supporting the Toyotomi Clan, fought a decisive battle in the Sekigahara field. Mototane joined the West Squad and stayed in Ogaki Castle near the field. Once he heard that his side had been beaten, he quickly changed his sides, killed some of the lords of the West Squad, and surrendered to Ieyasu. That also resulted in his territory being maintained by the Tokugawa Shogunate, established by Ieyasu. Mototane must have had great tact.

Ogaki Castle

Very Defensive Castle built in Sandbank

After that, he started to build his new home base in 1601, which would be called Nobeoka Castle, on a hill in a sandbank which was sandwiched by the Gokasegawa and Osegawa rivers. The Main Tower, Main, Second and Third Enclosures were built on the hill from the top in a tiered form and they are all surrounded by stone walls. However, the Main Tower Enclosure actually did not have the Main Tower building. The sandbank was divided into warriors’ residences, including the castle, and townsmen area, by a moat which can be crossed over by only one bridge. Moreover, the rivers around the sandbank had no bridges at that time, which would be very defensible. If enemies somehow arrived at the Main Gate of the castle at the foot, they would need to pass 5 gates and turn 11 times to reach the top.

The greatest stone walls of the castle are the ones called “The one thousand murder stone walls” which is about 19m high. They are the third highest stone walls in the Kyushu Region, following Kumamoto and Kokura Castles. The top two castles were built by great lords under Hideyoshi Toyotomi and Ieyasu Tokugawa, such as Kiyomasa Kato and Tadaoki Hosokawa, who also had much larger territories than Mototane who was just a local lord. In addition, the stone walls were piled using natural stones which would have been impossible to pile to such height, unless an excellent stone wall guild had been invited. Mototae must have had more power and a better connection than we expect. The nickname originates from the scale of the stone walls which would collapse and kill 1,000 soldiers below the walls if the corner base stone was pulled out.

Mototane is suddenly Fired

Mototane was suddenly fired by the shogunate in 1613. He had accommodated his wife’s relative who caused a trouble in the Tsuwano Domain and escaped from it. The domain’s lord, Naomori Sakazaki was monomaniac and sued Mototane in the Shogunate Court. Though it is still uncertain if that really caused such a serious outcome, the fact is that Mototane emerged and left in a short time. His work should be studied more. Nobeoka Castle and the area around it called the Nobeoka Domain were followed by the Arima Clan, which completed the castle building some turrets in 1656. During the peaceful Edo Period, bridges were built over the rivers around the castle and the Drum Tower in the Main Tower Enclosure which announced the time to people. Luckily, no battles happened to the castle until the end of the Edo Period when the Naito Clan took over.
