196.Sadowara Castle Part2

Visiting the castle ruins might be lucky to you.

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.

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.

196.Sadowara Castle Part1

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.

The ruins of Obi Castle

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.

Living and Religious places in Castle

The enclosures on the upper tiers were used as another pivot point as well as a place for living. The team found traces of kitchen stoves and a well, which were restored with a hut on the Southern Upper Tier Enclosure at the same time as the stone walls. The Southern Enclosure on the top of the tiers is used as the rest house, which is another viewing spot.

To reach the Main Enclosure on the top of the mountain, you will pass and see a larger pond being covered with stone mounds as well, called Hi-no-ike or the Sun Pond. This is actually not a reservoir but a well, which had been famous as a holy place since the Ancient Times before the castle was built. That’s why people in the castle used it for religious services.

Main Enclosure is used as Shrine

Around the top of the mountain is the Main, Second, Third Enclosures, but you can not access the two of the latter because they are privately owned. You will eventually go to the Main Enclosure on the top, which is now used as Nitta Shrine. As for the castle ruins, you can walk around the enclosure, called Musha-bashiri or the Defense Passage, and see the partially remaining original stone walls which are also uncertain as to who first built them.

Later History

After Kanayama Castle was abandoned, the Tokugawa Shogunate banned people from entering its mountain area to provide Matsutake mushroom to the shoguns during the Edo period. In fact, the Matsutake produced at the mountain was served to the Imperial Families until 1964.

A view of the Eastern hiking course, there are still Japanese red pines that could provide Matsutake mushroom, but they can’t produce it now because of aging

The shogunate also conserved the former area of the Nitta Manor by building religious facilities such as Serada Toshogu Shrine, Kinryuji and Daikoin Temples as they had declared the shoguns were a branch of the Nita Clan, which meant they were descendants of the Minamoto Clan. Even the shogunate needed the authority to govern the whole country. As for castle ruins, Kanayama Castle ruins were designated as a National Historic Site in 1934. Ota City has been excavating and developing them as a historical site since 1995.

My Impression

When the Yura Clan was banished from Kanayama Castle, only the lord’s mother, Myoinni was against the idea of Hojo Clan keeping the castle. Even after she gave it up, she joined Maeda’s troops to attack the Hojo Clan in 1590 when she was already 77 years old. That caused the Yura Clan to survive while the Hojo Clan to decline in the end. I guess if she and the Yura Clan could still stay in the strong Kanayama Castle even with only a few defenders, there might have been a dramatic event at the castle when Hideyoshi invaded the Kanto Region like Nagachika Narita fought with Mitsunari Ishida at Oshi Castle.

How to get There

I recommend using a car when you visit the castle ruins because there are no buses that go directly to the ruins available. It is about a 10-minute drive away from Ota-Kiryu IC on the Kita-Kanto Expressway. There are several parking lots at the foot, halfway up, and at the top of the mountain.
If you want to use public transportation, it takes around 1 hour from Ota Station. It would be better to take a taxi from the station.
From Tokyo to Ota Station: Take the JR Ueno-Tokyo Line from Tokyo Station and transfer to the Ryomo limited express on the Tobu Isesaki Line at Kitasenju Station.

That’s all. Thank you.
