Iyo province – 日本200名城バイリンガル (Japan's top 200 castles and ruins)

81.Matsuyama Castle Part1

Yoshiaki Kato devoted himself to the construction of this castle.

Location and History

Yoshiaki Kato builds Castle as his new Home Base

Matsuyama City in Ehime Prefecture is one of the most popular tourist spots in Japan, which is also known for attractions such as the Dogo Hot Spring. In fact, the area around the hot spring was the center of Iyo Province, the former Ehime Pref. until the Middle Ages. The Kono Clan governed the province by building Yuzuki Castle beside the spring. However, the clan declined during the unification of Japan by Hideyoshi Toyotomi and Ieyasu Tokugawa. When the Tokugawa Shogunate was established by Ieyasu after the Battle of Sekigahara in 1600, it gave a large territory in Iyo Province to Yoshiaki Kato who distinguished in the battle.

Yoshiaki was an excellent general who worked under Hideyoshi and Ieyasu, joining many battles including the invasion of Korea. He built the Matsuyama Castle on Katsuyama Mountain which is 132 meters high, using his knowledge about the modern technology and his own experience building castles. The situation was still unstable and it is also said that Yoshiaki quarreled with Takatora Todo who divided Iyo Provence with him. Yoshiaki completely devoted himself to the construction of the castle from 1602 to 1627 until he was transferred to Wakamatsu Castle in the Tohoku Region. Just after the launch of the construction, he renamed Katsuyama (which means Win Mountain) Matsuyama (which means Pine Mountain). For the Japanese at that time, the word Matsu or Pine was a lucky one which can be seen in other castles’ names like Wakamatsu, Matsumoto, and Matsusaka. This is the origin of the names of Matsuyama Castle and City.

Strictly protected Mountain Part and Convenient Large Foot Part

The top area of Katsuyama Mountain was like a shape of a tongue which became the Main Enclosure. In addition, another enclosure called Hondan or the Central Compound was built for the Main Tower, on the highest point of the Main Enclosure. The style of the Main Tower is called Renritsu-siki or the Tower Grouping, which refers to the Large and Small Main Towers and turrets being connected by the Hall Turrets like a corridor. The first Large Main Tower was said to have five levels. The Second Enclosure was built at the foot of the mountain for the Main Hall for the lord. The enclosures mentioned above were all surrounded by high stone walls. The Main Route connecting the Second and Main Enclosures was built complexly to avoid enemies from attacking easily. Moreover, the route was surrounded on both sides by long-line stone walls called Nobori-Ishigaki or the Climbing Stone walls. This stone wall style was rare and introduced by the lords who joined the invasion of Korea, including Yoshiaki Kato. Finally, The Third Enclosure, which was the largest one in the castle, was built outside the Second Enclosure and surrounded by water moats for government offices and high-ranking warriors’ houses.

After Yoshiaki was transferred in 1627, the Gamo Clan followed the castle construction, completing the Second Enclosure. The Hisamatsu-Matsudaira Clan followed the Gamo Clan in 1635 and continued the construction. It had been said the clan reduced the levels of the Main Tower from five to three for some reasons. According to the recent research, it was founded the Central Compound as the base of the tower was moved and renovated. It could be because the ground of the original compound was weak. It is possible that the first thing that the clan built was the three-tier main tower. The clan also completed the Third Enclosure by building another Main Hall in it in 1687.

Restoring Main Tower and Trial during Meiji Restoration

Fortunately, no battle happened at this castle, however, other natural disasters hit the castle. In 1784, most of the buildings on the Central Compound including the Main Tower were burned down by a lightning fire. The Matsuyama Domain led by the Hisamatsu-Matsudaira Clan couldn’t afford rebuilding them. After a while, the domain somehow restore them in 1853 at the end of the Edo Period. The restored buildings are thought to have the same designs as the previous ones. That’s why the Main Tower of this castle is the newest Main Tower of the twelve remaining ones in Japan.

The remaining Main Tower of Matsuyama Castle was restored in 1853

The Hisamatsu-Matsudaira Clan originally used only Hisamatsu as their family name. However, the founder of the clan, Sadakatsu and that of the Tokugawa Shogunate, Ieyasu were brothers but with different fathers. For this reason, Sadakatsu was allowed to use the family name Matsudaira as a relative of the shogun. This had been fortune during the Edo Period, while unfortune during the Meiji Restoration when the shogunate was defeated. The clan had to support the shogunate and invade the territory of the Choshu Domain which would be a winner of the restoration. They feared the revenge of the Choshu which actually was coming to Matsuyama Castle and would destroy it. Then, the Tosa Domain led by the Yamanouchi Clan, which had a close relationship with Hisamatsu-Matsudaira Clan, saved it. The domain troops intentionally occupied the castle before the Choshu troops arrived to avoid the Choshu doing anything without permission.

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.

The range of Iyo Province and the location of the castle

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.

82.Ozu Castle Part1

Many clans developed Ozu Castle and the area around.

Location and History

Utsunomiya Clan first builds Castle

Ozu Castle was located in the southern part of Iyo Province on Shikoku Island, which is now Ozu City in Ehime Prefecture. The castle was first built on a hill called Jizogadake by the Utsunomiya Clan in the 14th Century. This location was near the intersection of Ozu-Uwajima Road and Hijikawa River, an important point for transportation. The Utsunomiya Clan eventually became one of the local warlords in the province during the Sengoku Period in the late 15th to the 16th Century.

Takatora Todo modernizes Castle

After Hideyoshi Toyotomi achieved his unification of Japan, Takatora Todo, who worked under Hideyoshi owned Ozu Castle in 1595. He was based in Uwajima Castle, but he modernized both Ozu and Uwajima Castles. The details of improved Ozu Castle by Takatora are uncertain, because the ruins of it are under the current Ozu Castle. However, it is thought that the basic structure of the castle was completed by him. The Main Enclosure was on the hill beside Hijikawa River flowing from the east to the north of the castle. The Second Enclosure was below the hill on the opposite side of the river. Both enclosures were surrounded by the Inner Mort in the south and west. The Third Enclosure and the Outer Moat were also outside of them. The water of the moats was from the river, so the castle is also called a River Castle.

Yasuharu Wakizaka builds Main Tower?

In 1609, Yasuharu Wakizaka, was transferred from Sumoto Castle to Ozu Castle as the founder of the Ozu Domain. It is said that he built the four leveled Main Tower in the Main Enclosure. Some historians also speculate that he might have moved the Main Tower of Sumoto Castle to Ozu. This is because the sizes of the stone wall bases for both castles are almost the same, according to the recent research. The two two-story turrets called Daidokoro-Yagura and Koran-Yagura were built at both sides of the Main Tower, connected by the Passage Turrets. Many other turrets were also built in the important positions of each enclosure.

Kato Clan maintains Castle

In 1617, the Kato Clan was transferred from Yonago Castle to Ozu Castle, which governed the castle and the Ozu Domain over 13 generations until the end of the Edo Period. The domain didn’t have a large territory (60 thousand rice of koku) which meant they were not rich. However, it promoted industries such as Tobe pottery, Japanese papers and Japan wax. It also founded the domain school called Meirinkan to educate warriors. At the end of the Edo Period, one of the warriors, Ayasaburo Takeda learned the Western military science after graduation. He lastly built the first Western style castle called Goryokaku in Hakodate, Hokkaido Island, he also worked as the instructor of the Tokugawa Shogunate.

As for Ozu Castle, the Second Enclosure became the center of the castle in the peaceful time, having the Main Hall, warehouses surrounded by the Main Gate and some turrets.
