An impregnable castle on the border of Wakasa Province

Location and History

Katsuhisa Awaya reclaims Castle

What is now Fukui Prefecture was divided into Echizen Province in the Northeast and Wakasa Province in the Southwest. In the 16th Century during the Sengoku Period, the Asakura Clan governed Echizen while the Takeda Clan owned Wakasa. Sagaki-Kuniyoshi Castle was in Wakasa Province near the border between both provinces. Sagaki comes from the name of the area around the castle and Kuniyoshi originates from the name of the person who first built the castle sometime before the Sengoku Period. People at that time usually called it “Sagaki Castle” and the other name “Kuniyoshi Castle” became popular later. As a result, historians and history buffs often call it Sagaki-Kuniyoshi Castle, using both names.

The location of the castle

Comparing the Asakura and Takeda Clans, Asakura were much stronger than Takeda. Asakura tried to extend their power to Wakasa Province, in response, Takeda wanted to rely on Asakura. However, Takeda’s retainers, such as one of the senior vassals, Katsuhisa Awaya, rebelled against them. Katsuhisa reclaimed an abandoned castle to prevent the Asakura Clan from invading Wakasa Province, called Sagaki-Kuniyoshi Castle. The castle was built on a steep mountain with a height at 197m near the border of Echizen Provence. People who went in or out of Wakasa Province had to pass a ridge beside the mountain, so the castle was the pivot of defense for the province. The lord of the castle usually lived in the Main Hall on the valley below the mountain, but used the mountain part when a battle broke out.

The Asakura Clan attacked Sagaki-Kuniyoshi Castle 5 times between 1563 and 1567 to crush the rebellion. However, all the attacks failed because the rebel army and the castle were so strong. The battles between them occurred as follows. The warriors, their families, and other people around the castle gathered on the mountain carrying ammunition, stones, and wood. Meanwhile, some defenders hid in ambush beside the route to the castle. When the attackers got close to the castle on the route, the defenders made a surprise attack on them. After that, when the attackers climbed up to the mid slope on the mountain, the defenders shot guns and arrows, and threw the stones and wood all together. Many of the attackers were hit and fell into the valley, forcing the rest to withdraw. In addition, when the attackers looted property and crops away from the town and fields near the castle, the defenders made a night attack on Asakura’s positions. As a result, the castle was considered to be impregnable.

Castle is involved with Battle over Country

A fortunate opportunity for Katsuhisa came in 1570 when the great warlord, Nobunaga Oda attacked the Asakura Clan. Nobunaga visited Sagaki-Kuniyoshi Castle during his invasion of Echizen and praised Katsuhisa’s military achievement. The battle between Oda and the Asakura lasted until 1573 when the Asakura Clan was defeated. Nobunaga gave Wakasa Province to one of his senior vassals, Nagahide Niwa whom Katsuhisa served. Times rapidly changed after Nobunaga was killed in the Honnoji Incident in 1582. Nobunaga’s former retainers, Hideyoshi Hashiba and Katsuie Shibata were against each other for the initiative. Katsuie was in Echizen Province while Nagahide supported Hideyoshi. That meant Sagaki-Kuniyoshi Castle became a castle at the tense border between two provinces again.

Katsuhisa’s boss, Nagahide was responsible for constructing Azuchi Castle, famously built by Nobunaga Oda. That meant Nagahide had advanced techniques for improving castles. Sagaki-Kuniyoshi Castle had basically been made of soil, but was fortified using stone walls. In the end, the battle between Hideyoshi and Katsuie happened in another place before Hideyoshi won. During the unification of Japan by Hideyoshi followed by the Tokugawa Shogunate, the castle changed hands several times. The castle still continued to be improved using stone walls, but the mountain part was eventually abandoned. Instead, only the Main Hall part in the valley was used because it was convenient for the government. In 1634 when the Sakai Clan, the lords of the Obama Domain including Wakasa Province, built the Sagaki magistrate’s office, the castle was entirely abandoned.

156.Kamaha Castle Part1

A mountain castle with advanced systems

Location and History

Border Castle between Northern and Southern Omi Province

Kamaha Castle was a mountain castle during the Sengoku Period, which was located in Omi Provence (currently the modern day location of Shiga Prefecture). Its position was in the central area of the province, which at the time was divided into two parts, the northern part and the southern part. As a result, the two warlords from the Rokkaku Clan in the south and the warlord from the Azai Clan in the north were constantly gaining and loosing castles each other. Kamaha Castle was built on one of the ridges, which was 384 meters high, of Mt. Ryozen,. The name “Kamaha” which means “Sickle Blade” got its name from the shape of the ridge with its steep sides. The castle was located near a major road called “Nakasendo”, which was conveniently located for battle making it easier for transportation as well.

In the middle of the 16th Century, during the Sengoku Period, the Hori Clan was the ruler of the castle. The clan frequently changed their masters depending on the situation. In one instance, back in 1553, the Rokkaku Clan attacked Kamaha Castle, forcing the Hori Clan to escape, eventually surrendering the castle completely. However, the Hori Clan would eventually form an allegiance with the Azai Clan, most likely because the Azai Clan was gaining a lot of power at that time. Back in 1570, The Azai Clan fought Nobunaga Oda, where Hidemura Hori sided with Nobunaga who was easily persuaded by Hideyoshi Hashiba, the eventual ruler of Japan. This was the destiny of lord of the border castle.

Harsh Fate of Hidemura Hiri, Lord of Castle

Since Hidemura formed an allegiance with Hideyoshi, the Azai Clan were eventually beaten. Furthermore, Hideyoshi assisted Hidemura defend Kamaha Castle from an Azai Clan attack in 1571. This resulted in Nobunaga, Hidemura and Hideyoshi capturing Odani Castle (the home base of the Azai Clan) in 1573. A year later (in 1574) shortly after the succession, Hidemura was fired by Nobunaga due to Hidemura’s senior vassal’s failures. The primary reason for this is still unknown, but perhaps we can assume that this was purely the cruelty of Nobunaga’s character. Some historians speculate that there was a power imbalance since Hidemura was getting more powerful through his allegiance with Nobunaga. It was well-known that Hidemura accumulated more territory than Hideyoshi, who at the time was Nobunaga’s important retainer. Nobunaga might have the rebellion by Hidemura, or perhaps he wanted to take the territory for him. As the famous Chinese proverb goes “When the nimble rabbit dies, the hunting dog will be cooked”, so too was the fate of Hidemura. Finally, there is a strong belief by historians that Hidemura was hired by Hideyoshi and his brother Hidenaga in the end.

Systems of Castle improved uniquely

Kamaha Castle was finally abandoned in 1575. Some historians assumed that because the castle was made of soil, and that it was inferior to other castles, that it was abandoned sooner than other castles. However, according to a more recent excavation, it was revealed that Kamaha Castle actually had an advance system compared to other mountain castles. Kamaha Castle had at least a 3-level large turret, like a Main Tower, in the northern enclosures of the castle. This turret was thought to be used by defenders who shot arrows against attackers, as well as a large ditch located in front of it. If attackers had the misfortune of getting stuck in the ditch, it would give a clear and perfect sight for the defenders. Many enclosures were surrounded by stone walls. Moreover, the main enclosure at the center of the castle had its entrance with a square space surrounded by stone walls and steps called “Koguchi”. These types of systems were seldom seen in castles that were built after Azuchi Castle which Nobunaba built back in 1579. Based on these findings, Kamaha Castle was truly more advance than Azuchi Castle.

On the other hand, there were some differences between Kamaha Castle and Azuchi Castle as well. The large turret in Kamaha Castle was placed on earthen walls, and not on stone walls. These stone walls supported the earthen walls which prevented them from collapsing. In the case of Azuchi Castle, its main tower was built on stone walls directly. The Koguchi entrance of Kamaha Castle was designed for the gate of the main hall, and not for defense. Koguchi entrances built after Azuchi Castle exhibited more defensive capabilities, combined with complex routes. Historian often speculate that the systems used in Kamaha Castle had been improved uniquely, but was eventually replaced with other systems which were first seen in Azuchi Castle. However, the design of Kamaha Castle ‘s large turret might have been used for the main towers of other castles. This is because Hideoyoshi who would eventually build Osaka Castle included its main tower, must have seen the large turret when he worked with Hidemura at Kamaha Castle.

143.Mino-Kaneyama Castle Part1

The home base of the brave Mori Clan

Location and History

Mori Clan’s Severe History

Mino-Kaneyama Castle was located in the eastern part of Mino Province, what is now modern day Gifu Prefecture. The castle was built on a mountain which was sandwiched between Kiso-gawa River in the north and Nakasendo Road in the south. That meant it was an important point for controlling transportation during the Sengoku Period when many battles occurred. It was said that it was first built by the Saito Clan in the first 16th Century, and called Uho Castle in its first stage. After that, it was featured since the Mori Clan owned the castle in 1565 and renamed it Kaneyama Castle. The Mori Clan worked under the three rulers; Nobunaga Oda, Hideyoshi Toyotomi and Ieyasu Tokugawa from the Sengoku to the first Edo Periods. If you look into the history of the clan, you will see how severe their lives were and what they did to survive.

Lords and Brothers are killed in battles one after another

Yoshinari Mori was the lord of the clan in the late 16th Century, who served Nobunaga Oda since Nobunaga did not own many territories. That’s why he was promoted to be the lord of Mino-Kaneyama Castle during Nobunaga’s reign of Mino Province. However, Yoshinari had to join many battles in other provinces through Nobunaga’s instructions. Yoshinari was killed in a battle against the Azai and Asakura Clans in Omi Province (now modern day Shiga Pref.) in 1570. Yoshinari’s son, Nagayoshi followed his father’s position and was also active under Nobunaga.

He was often referred to Daredevil Musashi (it is part of his official title as the governor of Musashi Province). His three young brothers became Nobunaga’s pages, one of whom was Ranmaru, a famous historical person in Japan. This is because the cast for him is always performed with that for Nobunaga in modern plays showing the Honnoji Incident in 1582 where Nobunaga was killed. Nobunaga actually showed favor to Ranmaru who became the 3rd lord of Mino-Kaneyama Castle after Yoshinari was promoted to be another lord. However, the truth is that all the three brothers were killed in the incident.

Only One Brother is left as Next Lord

After the Honnoji Incident, Nagayoshi went back to Mino-Kaneyama Castle and followed Hideyoshi Toyotomi who was Nobunaga’s successor. In 1584 when the Battle of Komaki-Nagakute between Hideyoshi and Ieyasu Tokugawa happened, Nagayoshi joined a feint attack. However, Ieyasu noticed this plan, so he then ambushed and suddenly attacked it. Unfortunately Nagayoshi was instantly killed by a gun shot. As a result, Only Tadamasa, the youngest brother would be left to became the next lord of the Mori Clan. Nagayoshi actually left a will before his death, stating that Tadamasa shouldn’t be the lord of Mino-Kaneyama Castle. His intention is uncertain, but it might have been because he did not want Tadamasa to join battles and risked being killed.

Tadamasa followed Nagayoshi’s position which included the lord of Mino-Kaneyama Castle through Hideyoshi’s instructions. He worked under Hideyoshi, but changed his master to Ieyasu Tokugawa who killed his brother, but would be the next ruler after Hideyoshi died. There might have been other reasons for him to do this, but the main reason was to make a cool-headed decision in order to survive. He was finally promoted as the lord of Mimasaka Province which was a larger territory than before in 1603. He was transferred from Mino-Kaneyama Castle to another in 1600.

One of Shokuho Style Castles

As for Mino-Kaneyama Castle itself, it was improved as the Mori Clan was becoming more powerful. The castle had several enclosures on many tiers on the mountain. There were the Main Enclosure on the top, the Barbican Enclosure on the mid slope, and the Second and Third Enclosures between them. It was one of the typical Shokuho style castles which Nobunaga, Hideyoshi, and their retainers built around Japan at that time. The style had three major features; building stone walls, stone foundations for buildings and roof tiles. These items were originally used for temples, high-class government houses and Imperial Palaces before that time. Nobunaga started to use them on his and his retainers’ castles to show his authority and power similar to his Azuchi Castle. The enclosures of Mino-Kaneyama Castle were surrounded by stone walls. At least, some buildings on the Main Enclosure were built on stone foundations using roof tiles. However, the castle was abandoned after Tadamasa moved to another castle in 1600.
