Walking around Castle Ruins

The Enclosure which was supposed to be a Former Stable is a little far from the main portion of the castle. It was used as a lookout as well.

The castle also had many dry moats dug on the mountain in both vertical and horizontal directions to prevent enemies from attacking. You can still see some of them remained.

The castle ruins now have many routes like network and many enclosures for stop and rest, so you can enjoy walking and relaxing as well as learning history.

Later History

After Okoh Castle was abandoned, the Chosogabe Clan was unfortunately fired by the Tokugawa Shogunate. The Yamanouchi Clan from Kakegawa Caste came to govern Tosa Province and lived in Kochi Castle. The remaining Ichiryo-Gusoku group suffered from the Yamanouchi high-class warriors as the low class ones during the Edo Period. However, due to their rebellious spirit, some heroes in the Meiji Restoration such as Ryoma Sakamoto and Shintato Nakaoka appeared from the low class to change Japan later.

As for the castle ruins, they were first developed as a normal park with cherry trees planted. The excavation was done between 1985 and 1990. Since then, the ruins have been developing as Okoh Mountain Historical Park. They were finally designated as a National Historical Site in 2008. In addition, Kochi Prefectural Museum of History was built beside the park in 1991, where you can learn more about the castle and the Chosogabe Clan.

My Impression

I recommend visiting the three Chosogabe’s home base castles at once because they are close to each other. Kochi Castle basically remains as the Yamanouchi Clan’s legacy now, but the castle’s hill still has many tiers like Okoh Castle, probably it came from Chosogabe’s period. Though the ruins of Urado Castle were mostly destroyed by modern facilities, you can still see the great ocean view of Katsurahama Beach and the famous statue of Ryoma Sakamoto nearby.

How to get There

I recommend using a car when you visit the ruins.
It is about 10 minutes away from Nankoku IC on the Kochi Expressway.
The park offers a parking lot.
If you go there from Tokyo or Osaka, I recommend going there by plane. When you get there, it’s better to rent a car as there are few buses in the area.

135.Masuyama Castle Part3

Tonami City develops the ruins very well.

Features

Second Enclosure, Center of Castle

You will finally reach the Second Enclosure which had the only stone walls in the castle. They are more difficult to see now with the signpost saying the ruins of the stone walls.

The entrance of the Second Enclosure

The enclosure is the largest and the highest positioned enclosure in the castle, and it is surrounded by the thick earthen walls. For these reasons, historians have often speculated that this enclosure was the main one of the castle, though it is traditionally called “The Second Enclosure”.

The enclosure also has a mound called Shorodo or the ruins of the Bell Tower where a miniature version of the bell is built now. A turret was most likely there. You can see the next enclosure called the Ajichi Residence over the large deep dry moat form the mound.

Later History

After Masuyama Castle was abandoned, the Kaga Domain owned the ruins of the castle and planted cedar trees during the Edo Period. The cedar trees have been known as the Masuyama Sedars. Tonami City which now owns the ruins started to investigate them in 1987 and excavated them between 1997 and 2003. As a result, the ruins were designated as a National Historic Site in 2009. The city has been developing the ruins as a historical site so that visitors can visit them more easily.

My Impression

I think that the ruins of Masuyama Castle are very good study materials for visitors to learn more about what mountain castles were. If ruins of a mountain castle were left alone, it would return to its natural form. Trees and bushes would grow thick and the structures of the castle would collapse. That means visitors are often not sure what the mountain castle looked like or visiting the ruins can be dangerous. However, in the case of Masuyama Castle, Tonami City has developed the ruins to make it easier for visitors to learn more information. For example, bushes are always cut alongside the route. Simple wooden fences and the signboard are built at each enclosure. Therefore, visitors can understand what the layout of the castle would have been and how the defenders would have protect themselves. That’s why I recommend visiting the ruins.

How to get There

I recommend using a car when you visit the ruins.
It is about 20 minutes away from Tonami IC on the Hokuriku Expressway.
You can park at the information center (Masuyama Jinya).
If you want to use public transportation, you can take a taxi from Tonami Station.
To get to Tonami Station from Tokyo: Take the Hokuriku Shinkansen super express and transfer at Shin-Takanoka Station to the Johana Line.

That’s all. Thank you.

135.Masuyama Castle Part1

An important mountain castle in Ecchu Province

Location and History

Ecchu Province in Sengoku Period

Masuyama Castle was a large mountain castle which was located in Ecchu Province (what is now modern day Toyama Prefecture). In the first 16th Century, Ecchu Province didn’t have a strong warlord, but was divided between the Jinbo Clan, the Shina Clan, the Ikkoshu Sect and others. The province had the Toyama Plain in the center, which was surrounded by hills in the south, the east and the west. They built a lot of mountain castles on the area of the hills to maintain their territories. Masuyama Castle was called one of the three greatest mountain castles in Ecchu Province followed by Moriyama Castle and Matsukura Castle.

The location of the castle

Masuyama Castle was located on the western edge of the hills sticking out of the Toyama Plain from the south. The Wada-gawa River flowed alongside the edge, so it could be a natural water moat. There were a lot of enclosures on the hill such as the First Enclosure and the Second Enclosure.

Defensive system of Masuyama Castle

To protect these enclosures, the castle had several defensive systems using natural terrains like ridges, cliffs and valleys. For example, some ridges were cut artificially to look like a trench, called Horikiri. Some cliffs were cut vertically, called Kirigishi. Some valleys were used as the dry moats called Karabori.

The soldiers could also get water from several wells easily in order to survive a long siege. Other castles such as Kameyama Castle were built on the hill next to Masuyama Castle so that they could work closely with each other. Even the castle town was developed on the foot of the mountain castle at its peak.

Kenshin Uesugi attacked it three times

It is uncertain when the castle was first built, but the Jinbo Clan owned the castle in the middle of the 16th Century during the Sengoku Period. In 1560, a great warlord by the name of Kenshin Uesugi invaded Ecchu Province and supporting the Shina Clan from Echigo Province (The east of Ecchu Province). The Jinbo Clan was sieged in Masuyama Castle to protect themselves. Kenshin wrote in his letter that Masuyama was an essentially dangerous place and impenetrable with lots of defenders. Kenshin attacked Masuyama Castle three times, and finally captured it in 1576.

After Kenshin died in 1578, Narimasa Sassa under the Oda Clan took over Masuyama Castle from the Uesugi Clan in 1581. After that, the Maeda Clan supporting the ruler, Hideyoshi Toyotomi and the Tokugawa Shogunate later owned the castle. Some senior vassals from the Maeda Clan stayed in the castle. That meant Masuyama Castle was always an important castle to rule that area. However, the castle was finally abandoned in 1615 due to the Law of One Castle per Province created by the Tokugawa Shogunate. It was said that a wife of the senior vassal who was called Sho-hime was also a daughter of Toshiie Maeda, the founder of the Maeda Clan who managed the castle around the end of its history.
