56.Takeda Castle Part1

Masahiro Saimura, who completed Takeda Castle, only earned 22 thousand koku of rice, which meant he could not afford to build great stone walls at the castle. It is considered that the construction of castle was backed up by Hideyoshi.

Location and History

Famous for Castle in Sky

Takeda Castle was located on Torafusu-yama or the Sitting-Tiger Mountain (at 354m above the sea level) in Tajima Province which is now the northern part of Hyogo Prefecture. The ruins of Takeda Castle recently became very popular among not only history fans but also general tourists as a Castle in the Sky. The ruins don’t have any buildings but their great stone walls remain on the high mountain, which look like they are floating on a sea of clouds when there are certain weather conditions in the morning in autumn to winter. It is also called the Machu Picchu in Japan. The Castle in the Sky is an attraction in the present time and you need to go further away from the castle ruins to see it. However, the nickname also came from the castle’s history and location.

Yamana Clan first builds Castle

Tajima Province is not popular among the present generation because the province was small and finally merged to become Hyogo Prefecture. However, it was very important in the past because of its location. In many years of the Middle Ages, the Yamana Clan owned several provinces in the northern part of the Chugoku Region or also called the Sanin Area. Tajima Province was the eastern edge of Yamana’s territory and had borders with Harima and Tanba Provinces. That’s why the Yamana Clan first built Takeda Castle around the 15th Century as a base of offence and defense. At that time, building castles on a high mountain was popular for lords to protect themselves. These castles including Takeda Castle were all made of soil, at that time, they didn’t use stone walls.

The situation became more complex in the 16th Century during the Sengoku Period when many battles happened. The power of the Yamana Clan decreased while other lords outside Tajima Province wanted to get more territory. For example, in 1571, Suketoyo Yamana, the lord of the clan invaded Tanba Province, however, it was counterattacked and Takeda Castle was temporarily captured by Naomasa Ogino from Kuroi Castle of Tanba in 1575. Suketomo thought he would also ask for help from the strongest warlord, such as Nobunaga Oda and the Mori Clan depending on the situation to maintain his territory. However, when Nobunaga sent troops led by Hidenaga (Toyotomi) Hashiba who was the little brother of Hideyoshi Hashiba, the later ruler of Japan, to Tajima Province in 1577, Nobunaga gained control of Takeda Castle (it is uncertain if it was caused by a battle or a surrender). After Nobunaga died in 1582, when Hideyoshi became the ruler, he ordered Hidenaga to stay and improved Takeda Castle. It could be because Ikuno Silver Mine was there, which made the owner very rich, near the castle. It is thought that building the stone walls on the top started then. The improvement was followed by Masahiro Saimura, another retainer of Hideyoshi, when Hidenaga moved to Wakayama Castle in 1585.

Masahiro Saimaura completes Castle

Masahiro was originally called Hirohide Akamatsu, a local lord in Tatsuno Castle, Harima Province. He surrendered to Hideyoshi when Hideyoshi invaded Harima Province in 1577, however, Hideyoshi took away his castle so that he had to become Hideyoshi’s retainer. Masahiro worked hard for Hideyoshi to get his original territory back some day. As a result, Hideyoshi gave Masahiro a territory, not in Tatsuno, but with Takeda Castle. Masahiro’s territory only earned 22 thousand koku of rice, which meant he could not afford to build great stone walls at Takeda Castle. It is considered that the construction of castle was backed up by Hideyoshi. Masahiro continued to contribute to Hideyoshi, such as joining the invasion of Korea, ordered by Hideyoshi. It is said that some gate structures of Takeda Castle were reflected by those of Japanese Castles in Korea, built for the invasion.

The great stone walls of Takeda Castle on the mountain

Takeda Castle was built on the mountain with three ridges; long ones in the north and the south, and a short one in the southwest. The Main Enclosure was on the top and had the Main Tower, but its details are unknown. Each ridge had several enclosures including a large one which could accommodate soldiers and supplies. The edge of the ridges was open to the outside, but was also protected strictly by a defensive gate. They were all surrounded by great stone walls, piled using natural or roughly processed stones in a method called Nozura-zumi. A professional stone-piling guild was called in to do this. One of the advanced things of this castle’s layout was that it included bypass routes between the three ridges. The defenders could move from one to another smoothly so that they were able to respond to enemies’ attacks flexibly.

Abrupt ending of Masahiro and Castle

Masahiro usually lived in his Main Hall at the foot while developing the castle town. He was also interested in Chinese studies and communicated with domestic Confucians and a high-class Korean official. It is said that he also built a shrine to Confucianism in the castle on the mountain. However, the lives of he and his castle suddenly ended. In the crucial battle between the East Squad led by Ieyasu Tokugawa and the West Squad led by Mitsunari Ishida which happened in 1600, Masahiro joined the West Squad. When Masahiro heard about Mitsunari being defeated by Ieyasu at Sekigahara field, he switched to support the East Squad. He burned the castle town around Tottori Castle where another lord supporting the West Squad lived, to show his loyalty to Ieyasu. However, Ieyasu’s decision was to force Masahiro to kill himself by performing Harakiri to put the responsibility of the burning on him. This was an incomprehensible conclusion, but some historians speculate that Ieyasu and his Tokugawa Shogunate also wanted to secure Ikuno Silver Mine by removing possible rebels like Masahiro.

14.Mito Castle Part1

Mito Castle was located in the modern day Mito City which is the capital of Ibaraki Prefecture. The castle became the home base of the Mito-Tokugawa Clan, one of the three branches of the Tokugawa Shogun family. However, the castle looked very different from those of the other branches the shogun.

Location and History

Castle is built using Natural Hazzard

Mito Castle was located in the modern day Mito City which is the capital of Ibaraki Prefecture. The castle became the home base of the Mito-Tokugawa Clan, one of the three branches of the Tokugawa Shogun family. However, the castle looked very different from those of the other branches, Nagoya and Wakayama Castles, and the shogun’s Edo Castle.

The range of Mito City and the location of the castle

It was said that the castle was first built by a local lord, the Baba Clan sometime in the early Middle Ages. It was built on a diluvium plateau sandwiched between Nakagawa River in the north and Senba Lake in the south. Its original location was defensive due to the natural hazard, so it could be easy for the lord to build the castle on it. However, it was thought that the early stage of the castle was still small probably with only the lord’s residence on the eastern edge of the plateau.

As time passed by, the castle was followed by greater lords, the Edo and Satake Clans, and was developed larger and larger. The Satake Clan was one of the greatest warlords in the Kanto Region during the 16th Century in the Sengoku Period. The clan completed the basic structures of the castle, establishing the Main, Second and Third Enclosures in a straight line from the east to the west on the plateau. These enclosures were made of soil and divided by deep dry moats, which were typical methods for building castles at that time in eastern Japan. However, the clan was transferred to the Tohoku Region (they would build Kubota Castle there) in 1602 by Ieyasu Tokugawa, the founder of the Tokugawa Shogunate, since they didn’t support Ieyasu in the decisive battle in 1600.

Home Base of one of Three Tokugawa Branches

Ieyasu sent his sons to Mito Castle as it would be an important northern strongpoint to defend Edo Castle, the home base of the shogun. His youngest son, Yorifusa finally became the lord of the castle as the founder of the Mito Domain in 1609. Since then, the domain governed the castle and the area around it until the end of the Edo Period as one of the three branches of the Tokugawa Shogun family. The castle was also developed further, for example, the Main and the Second Enclosures were combined to make a new Main Enclosure, the Third Enclosure was renamed the new Second Enclosure, and the new Third Enclosure was built outside the others in the west.

However, unlike Nagoya, Wakayama and Edo Castles other Tokugawa relatives built using advanced items, such as Main Towers and high stone walls, Mito Castle was still made of soil using conventional technologies from eastern Japan. The reason for it could be that the lords of the Mito Domain usually lived in the Main Hall near the shogun in Edo, or there was no need to improve it more after the government of the shogunate became more stable. However, the most likely reason is that Mito Castle was strong enough without stone walls.

Mito Domain creates Imperialism and Exclusionism

The second lord, Mitsukuni Tokugawa, known as Mito-Komon in several historical plays, promoted arts and started to edit Dainihonshi or the History of Great Japan at the Shokokan institute in Edo, which would later be moved to the Second Enclosure of Mito Castle. This activity uniquely resulted in the idea of Imperialism although the domain was a relative of the shogunate which had taken the power from the Imperial Court.

The ninth lord, Nariaki Tokugawa, during the end of the Edo Period, established the domain school called Kodokan in the Third Enclosure of the castle in order to educate the retainers and open Kairakuen Garden to all the people. While the Western foreign ships were often seen around Japan, he opposed the policy of the shogunate to open the country to foreigners. As a result, the Imperialism of the Mito Domain led many other domains’ retainers to the movement for Imperialism and Exclusionism over the country, which finally caused overthrowing the shogunate, which was later called the Meiji Restoration. However, in the domain, the retainers were divided into Tengu Party (believing the movement) and Shosei Party (supporting the shogunate), which would bring into a serious tragedy.

Sad Killing each other by Mito Domain at Mito Castle

The final version of Mito Castle was like that the largest Second Enclosure became the center of the castle. It had the Main Gate, the Main Hall (also used as the government office), the Shokokan institute, the Corner Turret, and the Three-level Turret. In particular, the Three-level Turret was built as a substitute for a Main Tower. It was about 22m tall, which was too high for a three-story building, in fact, it had five floors inside.

The Tengu Party started a rebellion to ask the shogunate to stop trading with foreigners and to exclude them in 1864. In this war, the Tengu Party attacked Mito Castle the Shosei Party resided in, but failed. They eventually went west to ask Yoshinobu Hitotsubashi in Kyoto, who was a son of Nariaki and would become the last shogun, for what they wanted. However, they were arrested by Yoshinobu’s instructions and many of them were executed. The Shosei party also killed or persecuted the families in Mito of the Tengu Party. After that, the situation dramatically changed that the New Government was established and the shogunate was defeated in 1868. The survivors of the Tengu Party returned to Mito Castle and avenged against the Shosei Party. Some of the Shosei Party, who were on the run, attacked the castle the Tengu Party were resided in this time, but failed again. The strength of the castle was ironically proven by the tragedy between the retainers of the owner domain. Records say the number of the retainers was reduced from 3,449 to 892 during the internal conflict, which meant competent personnel from the domain ran out to modernize Japan.

79.Imabari Castle Part1

The monumental castle-building techniques of Takatoro Todo

Location and History

Takatora Todo builds Castle as his ideal Home Base

Imabari Castle is located in Imabari City in the northern part of Ehime Prefecture which was called Iyo Province in the past. The castle was built in 1604 by Takatora Todo who was a well-known master of castle construction. So far, he built several castles, for example, Wakayama and Akagi Castles when he was a retainer, Uwajima and Ozu Castles after he became a feudal lord of some parts of Iyo Province. However, Imabari Castle was his first home base which was built form the ground up independently. That means he was able to throw all his ideas and experiences in building the castle. That resulted in the castle becoming the monumental work of his castle construction.

Before the construction, Takatora joined the invasion of Korea in 1597 as the leader of the Japanese Navy. From the experience, he thought his new castle would need a good location for naval support and water transportation. That’s why the castle was built facing the Seto Inland Sea, as a sea and plain castle. Such a location could had been difficult and dangerous because the seaside ground was too soft to build a castle and enemies could attack the plain land easily. To prevent them from happening, berms called Inubasiri were first built for the base of the stone walls. The berms would also be used for standing fences when enemies would attack the castle. The castle was also surrounded by water moats tripled, to which the sea supplied water.

The stone walls of Imabari Castle were built on the berms

Simple but Defensive Layout

Other than the specific conditions for Imabari area, Takatora introduced new common and easy ways of building castles to Imabari Castle but it was strongly protected from sudden attacks. The main portion of the castle, which combined the Main and Second Enclosures, was simply square shaped, which was easy to construct and accommodate large troops. While it may be weak for defense, the portion was surrounded by the wide Inner Moat, high stone walls, and many turrets on the walls. The gates of the portion were strongly guarded with a square defensive space called Masugata. Moreover, to enter the Main Gate, visitors had to pass other small enclosure called Demaru or the Barbican in front of the Inner Moat, which had another Masugata, and go across the earthen bridge over the moat. Such structures can be seen in other castles which Takatora would later be involved in, such as Nagoya, Nijo, and Sasayama.

Takatora creates Multi-storied type Main Towers?

Another Takatora’s invention of building castles is a new type of Main Towers, called multi-storied type or “Soto-shiki”. The Main Towers had usually been built in a method, called look-tower type or “Boro shiki”, which had many decorations such as gables or “Hafu” and bell-shaped windows or “Kato-mado”. The new method had simply square floors diminished towards the top with minimal roofing. That made the Main Towers more efficient and also made the tower easier to protect. The Main Tower of Imabari Castle is said to be the first multi-storied type with five levels, which was built in the Main Enclosure.

In fact, it is not scientifically proven by excavation whether or not the Main Tower was really built in Imabari Castle. This is because the tower was demolished to be moved to another place when Takatora was transferred to Iga-Ueno Castle in 1608 after his short stay in Imabari Castle. Takatora once thought the tower should be used for his Iga-Ueno Castle, but he finally presented it to the Tokugawa Shogunate for the construction of Kameyama Castle which was ordered by the shogunate. According to the old photo of the castle’s Main Tower, it is certainly a five-level multi-storied type tower. This story was recorded only in Takatora’s biography or his clan’s annuals. There has been no evidence for the tower found in Imabari Castle such as the trace of its stone wall base. Some historians speculate that the Main Tower of Imabari Castle might have been built directly on the ground, not using any stone wall base.

The castle itself was followed by Takatora’s relative, Takayoshi Todo until 1635 and finally the Hisamatsu-Matsudaira Clan. The clan had been originally called just Hisamatsu, then it was allowed to use the family name Matsudaira which meant the shogun’s relatives after its lord accepted Ieyasu Tokugawa’s mother as the later wife. The clan governed the castle and the area, called the Imabari Domain, until the end of the Edo Period.
