Yogaiyama castle – 日本200名城バイリンガル (Japan's top 200 castles and ruins)

174.Ouchi Clan Hall/Konomine Castle Part3

Yamaguchi was focused on rebuilding again during the Meiji Restoration.

Later History

Yamaguchi was focused on rebuilding again at the end of the Edo Period. Until then, the Choshu Domain by the Mori Clan was based on Hagi Castle beside the Japan Sea. They wanted to move their homebase to Yamaguchi. This was because its location would be the best for communication with other domains to respond to the potential threats from Western countries, in fact, to be against the Tokugawa Shogunate. They eventually built Yamaguchi Castle beside Konomine Mountain, partly using the Western style with cannons, without the shogunate’s permission. They thought they could reuse Konomine Castle for the final battle. Eventually, they became one of the winners of the Meiji Restoration. As a result, Yamaguchi Castle was turned into the Yamaguchi prefectural office. In addition, Yamaguchi Prefecture produced 8 prime ministers of Japan, the largest number among all the prefectures, including the 1st prime minister, Hirobumi Ito and the late Shinzo Abe recently.

My Impression

I think the combination of Ouchi Clan Hall and Konomine Castle was a very good for both the government and defense like that of the Takeda Clan with Takeda Clan Hall and Yogaiyama Castle. It was also proven by the Choshu Domain that they wanted to use Konomine Castle again at the end of the Edo Period. However, in the case of the Ouchi Clan, it was too late to prepare for it. Maybe that’s because they thought Yamaguchi could never have been attacked by enemies because their government was very stable. Nobunaga Oda, who was the ruler in the 1570’s to the 1580’s, might have thought the same way before he was killed in the Honnoji Incident in 1582.

How to get There

If you want to visit Ouchi Clan Hall Ruins by car, it is about a 15-minute drive away from Yamaguchi IC on the Chugoku Expressway. There are parking lots in the northern and southern sides of the ruins. To get to Konomine Castle Ruins from there, you will need about another 20 minutes. There is a small parking lot on the mid slope of the mountain.
If you want to use public transportation, it takes about 15 minutes on foot from JR Kami-yamaguchi Station to get Ouchi Clan Hall Ruins. To get Konomine Castle Ruins from there, you will need about another 1 hour.
To get to Kami-yamaguchi Station from Tokyo or Osaka: Take the Sanyo Shinkansen super express and transfer to the Yamaguchi Line at Shin-Yamaguchi Station.

More needs to be done to improve this historical site

Features

Strong defense in Back side

If you have time, you should check out the back side of the castle. This is because the ridge on the back is very narrow, so original trail and the ruins along it seem to remain as it was. The Main Enclosure and the enclosure behind it are divided by an artificial ditch to prevent enemies from attacking form the back. The ditch is partly supported by stone walls to avoid collapsing, which is rare in Japanese castles.

Moreover, two earthen lookout platforms are in line on the ridge at the back of these enclosures. They are also partly supported by stone walls or stone mound, which are also uncertain who built or improved it.

The trail gets thin between the platforms

The trail goes beside the platforms and between them, which was made thin cut by vertical moats both sides. That meant the defenders on the platforms would see and counterattack enemies easily.

Later History

In the Edo Period, a stone statue of the Takeda Fudoson or Acala, which worshiped Shingen Takeda, was built in an enclosure between the Gate Ruins No.2 and No.3. It has since been called the Fudo Enclosure. After the Meiji Restoration, the castle site continued to deteriorate, so local people built the stone monument of the birthplace of Shingen Takeda in 1929 to preserve them. The title of the monument was written by Heihachiro Togo, a famous admiral of the Japanese Imperial Navy. The castle ruins have been designated as a National Historic Site since 1991.

My Impression

I recommend visiting both ruins of Yogaiyama Castle and Takeda Clan Hall at the same time because you will be able to see how the Takeda Clan protected their home base. They must have been like one castle or a set. On the other hand, let me ask one thing to Kofu City. In the ruins of Takeda Clan Hall, excavations and studies are often being done in recent years. However, why have the ruins of Yogaiyama Castle not been developed? More explanations is needed for historical fans at the site. Some parts of the ruins are covered with bushes. I hope in the future that the city will develop this mountain castle ruins as a set with Takeda Clan Hall.

How to get There

I recommend using a car when you visit the castle ruins because there are few buses to visit them.
It is about a 20-minute drive away from Kofu-minami IC on the Chuo Expressway. There is a parking lot in front of the trail entrance to the castle ruins.
If you want to use public transportation, you can take the Yamanashi-Kotsu Bus bound for Sekisuiji Temple from JR Kofu Station and ride to the end. It takes about 15 minutes on foot from the bus stop to get the entrance.
To get to Kofu Station from Tokyo: Take the limited express Azusa or Kaiji at Shinjuku Station.

The spot for hikers and history fans

Features

Castle Ruins on Hiking course

Today, the ruins of Yogaiyama Castle are on a hiking course as well as a historical site in Kofu City. The top of the ruins on the mountain is about 250m above the starting point of the trail at the foot. Therefore, you need to prepare for a long hike or a grueling climb to visit the ruins, which takes over 30 minutes to reach the top. The first half of your tour will be a pure hike by climbing a natural zigzagging trail. You may see some stone walls along the route, but they were probably built after the castle period.

Were these stone walls built after the castle period?

You will eventually find some signposts of Vertical Moat or Earthen Walls, which are around the entrance of the castle ruins. These actual ruins are partially covered with bushes, so you may not notice them without the signposts.

Original Gate Ruins along Trail

You will also find other ruins such as gates along the trail, however, the trail is not always on the original one. According to previous researches, the castle had 8 gates to reach the Main Enclosure on the top. As long as I checked, there are actually only 4 gate ruins with signposts along the current trail, which still look very defensive. I think they should be the original gates of No.2, No.3, No.6 and No.8.

The map around the castle

On the other hand, there are also other entrances of enclosures, which look like gate ruins without signposts. They are set straight in front of the enclosures, which mean not defensive, so may not be original and built later for hikers. If so, some original gate ruins (probably No.4, No.5 and No.7) are not on the current route probably because they are inconvenient for hikers.

In addition, the No.1 gate ruins seem to be on the route, but without a signpost, which I didn’t notice.

I think this is around the N0.1 Gate Ruins as some stone walls remain

Who built Masugata System of this Castle?

Out of the 4 original gate ruins with signposts, No.2 (with the first signpost of Gate Ruins) and No.3 (with the second one) are so great. They are surrounded by stone walls, forming a square space, called Masugata. The trail also turns right to exit the gate, plus, other enclosures are in the back of the gate and ahead of the route. That meant the defenders would counterattack the front and side of the enemies in the Masugata.

The No.2 Gate Ruins, the trail turns right

The No.3 Gate Ruins, similar to the No.2 Gate Ruins

This structure is seen in other castles using high stone walls, which would be built much later than Yogaiyama Castle. However, it is not uncertain who built or improved this system. If the Takeda Clan built it, it would be very advanced, if Mitsuyasu Kato improved it, he would have applied it from other castles like Kofu Castle to Yogaiyama Castle.

Main Enclosure, Largest one in Castle

The No.8 Gate Ruins are the entrance of the Main Enclosure. It is the largest enclosure in the castle on the top of the mountain, surrounded by thick earthen walls. There is only the stone monument for the birthplace of Shingen Takeda in it. There should be a good view point of Kofu city area, but unfortunately trees shut out the view.
