57.Sasayama Castle Part1

One of the castles which were built to surround Osaka Castle

Location and History

Tanba, Important Province for Rulers

Sasayama Castle was located in modern day Tanba-Sasayama City, in Hyogo Prefecture. Hyogo is a large prefecture which covers the western part of the Kansai Region. However, the castle was located at that time in Tanba Province which is much smaller than Hyogo Prefecture but was located in mountain areas just behind the northwest of Kyoto, the previous capital of Japan. That meant governing Tanba Province was very important to protect Kyoto and monitor if the lords in western Japan would do something effective to the central political circles.

Castle construction is ordered by Shogunate

Ieyasu Tokugawa defeated Mitsunari Ishida supporting the Toyotomi Clan in the Battle of Sekigahara in 1600 and established the Tokugawa Shogunate by becoming the shogun in 1603. However, the situation was still unstable because the Toyotomi Clan was still living in Osaka Castle, which was uncontrollable by the shogunate. In addition, there were many lords in western Japan, who were in favor of the Toyotomi Clan and might have been against the shogunate in the future. The response of Ieyasu to the situation was to build several strong castles around Osaka Castle to contain the Toyotomi Clan and divide the Toyotomi Clan and its favors. They are known as Nagoya, Iga-Ueno, Hikone, Zeze, Nijo in Kyoto, Kameyama and Sasayama Castles. These castles were built as the construction orders by the shogunate, which made lords including the Toyotomi Clan favors join at their own expenses. The side effects of the constructions were to reduce the lords’ money and force them to give up their rebellious split to be against the shogunate by showing the strong network of the castles.

The network of the castles around Osaka Castle, which Ieyasu built

The construction of Sasayama Castle launched in 1603, which was instructed by Terumasa Ikeda who was the lord of Himeji Castle, with the help of 20 lords from 15 provinces and was designed by Takatora Todo who was considered as a master of castle constructions. The castle was built on a hill called Sasayama, in the Sasayama Basin. The main portion of the castle was on the hill, using the natural terrain and building high stone walls over the hill. Other than that, the castle had simple flat square enclosures and double water moats surrounding it. That designs made it easier to build the castle, but it would made it weaker to protect the castle instead.

Castle is designed by Takatora Todo

To prevent enemies from attacking it easily, Takatora designed the castle’s entrances to be strictly protected using the Masugata system. The Masugata refers to a defensive square space which was surrounded by gates and stone walls where enemies would be locked out. Another defensive system that Takatora designed was the Umadashi. It refers to a square enclosure sticking out from the entrance connected by a narrow path among the moat. The enclosure had another moat in front of it, so its entrances were at both sides where the defenders could counterattack from them. Takatora established these structures in his own Imabari Castle which was completed in 1604.

Main Tower is not built

On the other hand, Sasayama Castle didn’t have its Main Tower in the Main Enclosure on the top. In fact, the stone wall base for the tower was built, however, the tower was not built. This was because the shogunate determined the castle would not need it as it would be enough to protect the castle without it. Another reason was that the lords working for the construction also needed to move to the another site for Nagoya Castle. That’s why Sasayama Castle was completed after only a half year of construction. Instead, several turrets were built in the Main Enclosure and the Main Hall for the lord was built in the Second Enclosure, which constituted the main portion of the castle.

The castle was first owned by Yasushige Matsudaira, a relative of Ieyasu Tokugawa. After the shogunate defeated the Toyotomi Clan in 1615, several hereditary feudal lords followed the castle to monitor non-hereditary feudal lords in western Japan as the Sasayama Domain, such as the Aoyama Clan which governed the area until the end of the Edo Period.

79.Imabari Castle Part3

This castle is beautiful and firmly built.

Features

Walking outside Inner Moat after getting out of Back Gate

The castle park also has the back gate called Yamazato-mon which was restored in 1990. To get out of the castle area, you have to go down a few stone steps, pass another Korai-mon style gate, and go across a narrow earthen bridge. The earthen bridge was originally wooden made which would have been fallen if a battle happened. The area around the gate is sunken, on the other hand, the area over the bridge extends upward.

After you go out of the park, you can try walking around the Inner Moat. The moat is about 50 to 70m wide and the stone walls inside are 9 to 13m tall. They look like a floating fortress!

Imabari Port, Source of Inner Moat

After looking around, you can check out how the sea water gets inside the Inner Moat of the castle. You can also see the water reservoir near the main entrance of the park. If you go along the waterway towards the source, you will reach the Imabari Port which was the castle port. It was located at the edge of the Middle Moat in the past. Because of that source, the surface level of the Inner Moat is changing depending on the tide.

Later History

After the Meiji Restoration, Imabari Castle was abandoned and all the castle buildings were eventually demolished or burned. The Main Enclosure was turned into the Fukiage Shrine in 1872 before the Fukiage Park was established including the Second Enclosure in 1914. That’s why the main portion of the castle inside the Inner Moat still remains, while the outside of the moat was all turned into the city area. Since the castle ruins were designated as a Prefectural Historic Site of Ehime in 1953, Imabari City has been developing and restoring them as a historical park as mentioned above.

My Impression

After walking around the Inner Moat to see the great view of the moat and the high stone walls, I noticed Imabari Castle was quite practical. Why did Takatora Todo make the Inner Moat around 50m wide and the stone walls around 10m high? I speculate that the defenders on the stone walls were able to hit the attackers outside the Inner Moat effectively by guns and arrows. On the other hand, the guns and arrows from the attackers could not be useful. I think Takatora built this castle that way. Imabari Castle was beautiful as well as so strong.

The height of the stone walls and the width of the Inner Moat may have been the best to protect the castle

How to get There

If you want to visit there by car, it is about 15 minutes from Imabari-Kita IC on the Nishi-Seto Expressway or about 20 minutes from Imabari-Yunoura IC on the Imabari-Komatsu Expressway. There is a parking lot beside the main entrance of the park.
By public transportation, you can take the Setouchi Bus bound for Imabari-Eigyosho from Imabari Station and get off at the Imabari-jo-mae bus stop or it takes about 30 minutes on foot from the station to get there.
From Tokyo or Osaka to Imabari Station: I recommend traveling by plane and when you get there you can take the bus or train to get to Imabari station.

That’s all. Thank you.

79.Imabari Castle Part2

A great appearance of a sea castle

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.

The Fukiage Shine

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.

No turrets were restored in the Main Enclosure except for the one corner

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.
