134.Toyama Castle Part1

A castle basically made using earthen walls and water moats

Location and History

Center of Ecchu Province

Toyama City started as the castle town of Toyama Castle and is the capital of Toyama Prefecture. The castle was first built by the Jinbo Clan in the first half of the 16th Century. It was in a flat area in the center of Ecchu Province, what is now Toyama Pref. The area was also the intersection of two of the major roads, the Hokuriku, and Hida Roads. It might have been dangerous to build a castle in such a place at that time. Many battles happened during this time, later known as the Sengoku Period. Warlords in the province usually lived in mountain castles like Masuyama Castle to protect themselves. In the case of Toyama Castle, it was protected by the Jintsu-gawa River and water moats surrounding the castle.

Narimasa Sassa unifies Ecchu Province

Many warlords such as the Uesugi Clan, the Ikkoshu Sect, and the Oda Clan battled over Toyama Castle. Narimasa Sassa finally took over the castle and governed the whole Ecchu Province in 1582. However, he was against the ruler, Hideyoshi Toyotomi. Hideyoshi attacked the Ecchu Province in 1585. The castle was destroyed for the first time, after Narimasa surrendered to Hideyoshi in the same year. Hideyoshi gave Ecchu Province to Toshinaga Maeda who would be the founder of the Kaga Domain in the Edo Period. In 1605, Toshinaga handed over the head of the domain to his successor, and moved from Kanazawa Castle, the home base of the domain, to Toyama Castle for retirement. He had the power to govern the domain because the successor was still young. He rebuilt Toyama Castle as his new home base.

Toshinaga Maeda completes Castle

It is said that Toshinaga completed the structure of Toyama Castle. The large Jintsu-gawa River flowed in the north of the Main Enclosure as a natural hazard. A floating bridge was built over the river, which would later become popular among the people. There was the Second Enclosure in the south, the Eastern Barbican Enclosure in the east, and the Western Enclosure in the west of the Main Enclosure to protect it. Each enclosure was independent. The enclosures were surrounded by a water moat. They were only connected to the Main Enclosure by an earthen bridge. These enclosures were basically made using earthen walls. They were partly covered with stone walls around the three main gates such as the front gate of the Main Enclosure. It is also thought the Main Hall was in the Main Enclosure and some turrets were built on the stone walls of the gates. The largest Third Enclosure was on the south of all other enclosures, which was used as the warriors’ houses. However, the castle was destroyed a second time when it was unfortunately burnt by an accidental fire in 1609 before Toshinaga had to move to Takaoka Castle.

Home Base of Toyama Domain

In 1639, Toshinaga’s nephew, called Toshitsugu Maeda, was allowed to establish a subsidiary domain called the Toyama Domain. He once thought he could build a new castle but decided to repair and reuse Toyama Castle due to a financial issue. Instead, he built the outermost earthen walls and water moats to protect the castle town. Toshitsugu’s son, Masatoshi, promoted industries, especially a patent medicine. The success of the medicine resulted in the drug sellers of Toyama being known in the whole country. The domain also planned to build the Main Tower but gave up because of a financial issue again. Instead, they built the Chitose Hall in the Eastern Barbican Enclosure to sometimes allow to people to enter it for festivals. In addition, the castle suffered damage from fires, floods, and earthquakes again and again throughout the Edo Period. The domain struggled to restore or repair it. Simple earthen walls and water moats might have protected the castle from many of the disasters and made it easier to restore and maintain.

119.Sugiyama Castle Part1

A castle which has both an advanced defense system and a mysterious history

Location and History

Simple but Popular Castle

Sugiyama Castle was located in Hiki District, what is now in the western part of Saitama Prefecture. The ruins of the castle recently became popular among history fans in Japan. The ruins are not so large and have no buildings and no stone walls. The ruins are all made of soil. In addition, it is also uncertain when and who built and used the castle. There are no clear records about the castle at all. So, what did the castle become famous for? The answer is that the castle had a surprisingly artful defense system for such a small local castle.

The location of the castle

“Sugiyama Castle Problem”

Historians have tried for a long time to find out when and who built Sugiyama Castle. However, their conclusions became more complicated. When the excavation team researched the castle ruins, they thought the castle was built and used around early 16th Century based on the unearthed relics. The Uesugi Clan, which governed the Kanto Region, had internal conflicts in the area around the castle at that time. The team speculates the clan built the castle. On the other hand, the researchers who study the layout of castles argue that the complex defense systems like Sugiyama Castle should have appeared later, such as in the late 16th Century. They think the Hojo Clan, which governed the Kanto Region after the Uesugi Clan, must have built such an advanced defense system. People call this discussion “Sugiyama Castle Problem”. The problem might even make the castle more popular.

“Textbook for Building Castles”

Sugiyama Castle was built on a hill. The hill measured 42m high from the base. The castle had 10 enclosures, including one in the center of the castle. The enclosures spread into three directions in the south, north and east. These enclosures were built to protect the center of the castle called the Main Enclosure. The west of the castle was a steep cliff with a river flowing below, which was a natural hazard. All the enclosures were surrounded by earthen walls and dry moats and connected by earthen or wooden bridges. The most important feature of its defense system was that all the entrances of the enclosures were protected by the frank attacks or Yokoya. Protection was provided by the clever layout of the L-shaped earthen walls and the route to the enclosures. The design of the castle was highly sophisticated, so it is now often called “a textbook for building castles”.

Castle may be Temporary

The excavation found that Sugiyama Castle didn’t have permanent buildings such as halls, turrets, and gates. It probably only had temporary buildings like huts and fences. It was also found that the castle was used for a short time because it was not modified before it was destroyed by fire. This means that the castle could have been built for a single purpose or battle. There were many other castles around Sugiyama Castle, which were also built probably for a single purpose. Many of these castles, such as Ogura Castle, had distinct features. Many battles happened around this area in the 16th Century during the Sengoku Period. It is thought that the warlords in this area built residential castles as well as single-use castles to survive. Even though Sugiyama Castle may have been one of the latter, it had a surprisingly technical defense system.

The map around the castle

Today, the ruins of Okoh Castle is well developed as a historical park. If you drive to the park, you can easily park your car at the mid slope of the mountain near the entrance of the ruins. If you walk up on the slope from the entrance, you will first arrive at the front of the high earthen walls of the the castle.

From Forth Tier to Third Tier

Then, if you walk around to the right direction, you can enter the Forth Tier through the entrance of the enclosure called Koguchi. The entrance is made narrow and curved by the earthen walls for defense.

The Third Tier is higher than the Forth Tier, surrounding the Final Tier like belt. The strong stone foundations surrounded by stone-piled earthen walls remain inside the enclosure. The building on the foundations would have been an important structure for the castle.

Final Tier, Center of Castle

The Final Tier is the highest enclosure of the castle, so it was thought that it had the turret like a main tower. There are no building remaining on the ruins, but you can see a very good view of the Kacho Plain with lots of rice fields instead. You can easily imagine the area around the castle has been warm and rich.

Second Tier to protect Final Tier

The Second Tier is opposite to the Forth Tier. The enclosure was separated by a ditch from the Final Tier to protect it. There is also a small enclosure named the Lower Final Tier between the Second Tier and the Final Tier, where another turret was probably built.
