Features

Entering Castle over Inner Moat using Sea Water

Today, Imabari Castle, which is now also called the Fukiage Park, has only its main portion surrounded by the Inner Moat, but still looks so great. The contrast of the high stone walls and Inner Moat is very impressive and may also be artistic. Some buildings were rebuilt that include the Main Tower on the stone walls to make it more attractive. It is still near the Imabari Port and uses the sea water for the Inner Moat, and maintains the sea castle atmosphere.

Visitors usually enter the castle from the main entrance which was one of the square Masugata spaces in front of the Inner Moat. You can go across the earthen bridge over the moat towards the main gate called Kurogane-gomon or the Iron Gate like the past visitors used to do. The gate is still surrounded by great stone walls, forming a Masugata space. It was actually restored in 2007 based on the Imabari Domain’s records and the excavation results, including some of the walls.

The stone walls use some huge ornament stones and one of which is the largest one in the castle. It is called Kanbe Stone, which was named after Kanbe Watanabe who was responsible for the castle construction under Takatora Todo. In fact, the gate space had another Korai-mon style building in the front, and in the past some visitors could be completely locked up in the gate. That was a way to protect the castle.

Several Turrets are restored in Second Enclosure

Inside the gate is the Second Enclosure, which is rectangular shaped. It had the Main Hall for the lord, and now has the statue of Takatora Todo riding a horse.

The three turrets at each corner were also restored in the present time, which were used for exhibitions. (the other corner of it is shared with the Main Enclosure.) Part of the Hall Turrets called Tamon-Yagura connecting the turrets above were also restored on the stone walls.

Imitation Main Tower is built in Main Enclosure

The Main Enclosure is next to the Second Enclosure, which is quadrate and around half the size of it. It now has the Fukiage Shine inside, but both enclosures look the one because there is no partition between them. In the past, there were mud walls between them, so visitors going to the Main Enclosure had to pass another Masugata space as well.

There were also four turrets at each corner, but only their stone wall bases are remaining except for the northern corner. This is where you can see the Imitation Main Tower. This tower was built in 1980 when it was still uncertain where the original Main Tower had been. It also doesn’t resemble the Multi-story type Main Tower Takatora created because the current one looks like a Look-out tower. This is probably due to the designer considering the popular design of the some towers at that time.

You can enter the tower passing the former Masugata space which is surrounded by the stone walls. It is actually a modern building which is used as a historical museum and an observation platform.

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.

77.Takamatsu Castle Part1

One of the three greatest sea castles in Japan

Location and History

Chikamasa Ikoma built Castle based on experience

Takamatsu Castle, one of the greatest sea castles in Japan, was located in Sanuki Province which is now Kagawa Prefecture. The name of the prefectural capital, Takamatsu City, actually originates from this castle. Chikamasa Ikoma, who was a warrior in the 16th Century during the Sengoku Period, first built the castle. Chikamasa took part in many battles such as those at Nagashino Castle, Ishiyama Honganji Temple (former Osaka Castle), and Bicchu-Takamatsu Castle under the ruler Hideyoshi Toyotomi. Chikamasa contributed to the unification of the country by Hideyoshi who gave Chikamasa Sanuki Province in 1587.

Chikamasa at first used the existing Hiketa Castle, but he decided to build a new castle as his home base. From his experiences, his concerns about the castle were:
・whether it would be able to get naval support during battles.
・whether it would be able to withstand gun attacks.
・whether it would be able to survive a long siege.
In the end, he devised Takamatsu Castle, which was completed in 1590.

Castle surrounded by Sea and Triples Moats

Takamatsu Castle was built facing the Seto Inland Sea to the north, making it possible to ship directly to the sea. The castle was also surrounded by water moats tripled in the other directions, to which the sea supplied water. The main enclosure which had the three-layer main tower was isolated in the inner moat, connecting to the second enclosure with only a wooden bridge called saya-bashi. The third enclosure was next to the second enclosure, which had the gate opening to the sea. The enclosure also had the main hall for the lord of the castle. Such a castle was classified not only as a plain castle, but also a sea castle. It would be impossible for enemies to completely besiege this castle with technology at that time.

Matsudaira Clan followed and developed Castle

The Ikoma Clan was allowed to maintain their territory of Sanuki Province for a while by supporting the Tokugawa Shogunate in the battle of Sekigahara in 1600. However, the clan was forcibly moved by the shogunate in 1640 due to their internal strife. After that, the Shogun’s relative, Yorishige Matsudaira was sent to Takamatsu Castle as a replacement for the Ikoma Clan. Though lords were basically not allowed to renovate their castles at that time, he developed and improved Takamatsu Castle by rebuilding the main tower and adding the northern and eastern enclosures. This was because he was also responsible for monitoring non-hereditary feudal lords in Shikoku Island, who might have been against the shogunate.

The Matsudaira Clan governed the castle and the area around as the Takamatsu Domain until the end of the Edo Period. In the peaceful time of the Edo Period, the beautiful view of the castle became a famous attraction for people. A guide book at the time says that the castle looks as if it is a floating castle on the waves from the Seto Inland Sea. The castle has also been said to be one of the three greatest sea castles in Japan.
