145.Kokokuji Castle Part1

Is this castle a symbol of peace or of battles?

Location and History

Kokokuji Castle was located in what is now Numazu City, Shizuoka Prefecture. The area of the city was in Suruga Province (now central part of Shizuoka Pref.) which many warlords tried to take over in the 16 Century during the Sengoku Period.

The location of the castle and the range of Suruga Province

The castle was on the southern edge of the hilly terrain of Ashitaka-yama Mountain. There was a marshland to the south, east and west of the castle which was as natural hazard that helped to protect the castle. The castle was built using the natural terrain of the mountain and marshland. The castle was also an important point for transportation. A road at the foot of the mountain called the Nekata Road passed beside the castle. In addition, the Takeda Road close to the castle ran from the Nekata Road to the Tokaido Road at the seaside.

The two roads are still connected to the castle ruins

The castle mainly consisted of three enclosures on the hill in a terraced manner. The Main Enclosure was at the highest, and there was a large deep dry moat behind the enclosure to prevent enemies’ attacks from the north. The castle even had ports on both sides for ships on the marsh.

The castle itself might have been simple but is well known for its history. This is because some history books say that Kokokuji Castle was the first castle for a famous warlord, Soun Hojo to govern. He was one of the earliest warlords in the late 15 Century who supported the Imagawa Clan in Suruga Province. He was given the castle by the clan in 1487. His success story starts at this castle, and he went on to capture a part of the Kanto Region. His descendants followed in his footsteps to capture the other parts of the Kanto Region.

However, there is no other evidence of the castle existing at the same time as Soun. The first appearance of the castle in a public document can only be traced back to 1549. At that time, Yoshimoto Imagawa ordered that the Kokoku-ji Temple be moved to another location to make space for building a new castle there. What is the truth about the matter? A historian gives us an interesting hypothesis that the castle was a temple called Kokoku-ji when Soun owned it. Kokoku-ji is originally a name of temple (“ji” means temple in Japanese). Kokokuji Castle is thought to be named after the Kokoku-ji Temple.

The historian suggests another speculation about why the castle was built. A period of peace once came to the area around Suruga Province with Imgawa, Hojo, and Takeda Clans when the castle was built. Castles were basically built for battles, but Kokokuji Castle might have been built for the meeting with the three clans or as a symbol of peace. It is said that the three clans had a conference for their alliance at the Zentokuji-Temple. The temple may have been Kokokuji Caste.

Unfortunately, the alliance broke in 1568, while Kokokuji Castle was involved in war. The lords of the castle were rapidly changed several times from the Imagawa Clan to the Hojo, Takeda, Toyotomi, and Tokugawa Clans. As the number of the lords increased, the range of the castle seemed to become larger. In 1601, Yasukage Amano under Tokugawa became the last lord of the castle and the founder of the Kokokuji Domain. He governed the area well, but he ran away from the castle because of trouble between his citizens and others. The castle was finally abandoned when the domain was abolished in 1607.

24.Takeda Clan Hall Part1

Were the people the castle, the stone walls, or the moats?

Location and History

Nobutora Takeda built Castle as Governor’s Residence

Takeda Clan Hall, which is also called Tsutsujigasaki Hall, was located in what is now Kofu City, the Prefectural Capital of Yamanashi Prefecture. I would say the hall is the origin of Kofu City. The Governor of Kai Province (now Yamanashi Pref), Nobutora Takeda first built the hall in 1519. The hall was not only for the official residence of the governor, but also for the home base of the Takeda Clan, so it is classified as one of the castles in Japan.

Its location had mountains behind on the north, and an alluvial fan spread down on the south from around there. This meant Nobutora was able to overlook the castle town and the area around. He built his hall on a square enclosure which was nearly 200m on one side, surrounded by earthen walls and water moats. This was a typical style of the residences for governors in Japan at that time, emulating the style of Shogun’s palace in Kyoto. In addition, he built another castle on a mountain about 2km away from the hall on the north, called Yogaisan Castle, for emergency. For example, he and his family could escape from the hall to the mountain castle when a battle happened. Indeed, his son, Shingen Takeda was born at Yogaisan Castle during the battle between Nobutora and the Imagawa Clan in 1521. The network of these castle was defensive enough to maintain their safety during that time.

Shingen Takeda’s saying related to Castle

Shingen, who was one of the greatest warlords in Japan, developed the hall as well, adding the West Enclosure for residences of his family and relatives on the west of the center enclosure in 1551. Apart from that, the Umadashi system, which refers to a round shaped sticking out defensive position, was built in front of the Main Gate on the east. It is also said that the hall for Shingen’s mother was built on the north. Each enclosure was surrounded by nearly 10m high earthen walls and over 5m deep water moats.

However, the hall seems to be misunderstood by many people. This comes from Shingen’s saying “The people are the castle, the stone walls, and the moats…” recorded in the military science book called Koyogunkan in the 17th Century of the Edo Period. The sentence means it is more important to win the people’s hearts than to build a strong castle, but many people later have been thinking it shows the reason why Shingen only had such a small castle in comparison to other castles for other warlords such as Nobunaga Oda and Kenshin Uesugi.

Takeda Clan Hall itself is much smaller than Nobunaga’s Azuchi Castle or Kenshin’s Kasugayama Castle, but it is because their periods or situations were different. In the case of Shingen, his hall started from the governor’s residence. It was common for governors to live in such a hall at that time. The Takeda Clan added defense systems like the network of the castles and Umadashi to deal with their situation. It was enough for them.

Katsuyori Takeda moved to another

In 1582, Shingen’s son, Katsuyori Takeda decided to move his home base to a large new castle called Shinpu Castle, because the situation changed. Katsuyori was threatened by Nobunaga, so Katsuyori needed a stronger and larger castle than the Takeda Clan Hall which was once abandoned. Katsuyori was unfortunately beaten by Nobunaga before the hall was used by the Oda Clan and the Tokugawa Clan again. It was finally abandoned in 1590, when the Tokugawa Clan built Kofu Castle near the hall.

149.Komakiyama Castle Part1

The castle had a very short life but rich history.

Location and History

Nobunaga’s Foothold

Komakiyama Castle was located on an 86m high mountain called Komakiyama, on Nobi Plain in Owari Province, what is now the western part of Aichi Prefecture. The mountain had no castle until Nobunaga Oda built a castle on it in 1563. The reason for it was that he wanted to move his home base from Kiyosu Castle in now Nagoya City to this castle. He aimed to capture Inabayama Castle, what is now Gifu City, which the Saito Clan owned at that time. Komakiyama was much closer to Inabayama than Kiyosu. However, it was very rare for warlords and their retainers to move their home to another. They always continued to live in places where their ancestors had been.

Three Distinct Features

Komakiyama Castle by Nobunaga had three distinct features. First, the Main Enclosure or Honmaru on the top was surrounded by stone walls made using huge stones. Some of the stones were carried from another mountain. At that time, building stone walls for castles was rare, and there was likely no other case like Komakiyama. It was one of the earliest examples of using stone walls as a show of authority.

The remaining stone walls on the mountain

Secondly, the castle had two residences for the lord, one was on the mountain, the other was at the foot. Other warlords who had a mountain castle also often had two residences. They usually lived in the one on the foot and used the one on the mountain when a battle happened. However, in the case of Nobunaga, he seemed to live in his residence on the mountain. He might have considered the mountain as a special place. Another similar example can be seen in Gifu Castle, his next home base.

Lastly, the Main Route went straight from the foot to the mid-slope of the mountain like Azuchi Castle, his last home base. It was abnormal for other warlords to have such a route on the mountain, because it was not defensive. The reason is still unsure, but it must have depended on Nobunaga’s idea. In addition, its castle town was built in an advanced way in an area where nothing existed prior. The town was divided orderly to accommodate warriors, merchants, and craftsmen separately. Such a way to develop castle town is commonly seen in those in the next century.

Ieyasu’s Stronghold

The life of the castle by Nobunaga was just four years, as he was successful in capturing Inabayama Castle in 1567. He moved his home base again to Inabayama castle and renamed it Gifu Castle. Komakiyama Castle was abandoned right away. In 1584, the castle was reused by Ieyasu Tokugawa when he fought with the ruler Hideyoshi Toyotomi in the Battle of Komaki and Nagakute. Ieyasu reinforced earthen walls and dry moats surrounding the castle to establish a stronghold there against Hideyoshi at Inuyama Castle. This battle resulted in a dead heat and Ieyasu showed his great presence towards the founder of the Tokugawa Shogunate later.
