Visiting the main portion of the castle

Later History

After the Meiji Restoration, Sasayama Castle was abandoned and all the castle buildings, except for O-shoin or the Large Study Hall out of the Main Hall, were demolished. The hall was used as a school and a community center for a while, however, it was unfortunately burned down by an accidental fire in 1944. After World War II, the Inner Moat out of the double water moats was filled to became a normal park. However, since the castle ruins were designated as a National Historic Site in 1956, the trend changed. Tanba-Sasayama City has been developing the ruins as a historical site such as the hall being restored in 2000 and the moat being dug up again.

Features

From Main Gate Ruins to Main Portion

Today, the ruins of Sasayama Castle have been developed by Tanba-Sasayama City with the remaining warriors’ houses and the castle town atmosphere. Visitors usually first visit the Main Gate Ruins in the north in front of the Outer Moat. Unfortunately, the gate and its Umadashi system were destroyed, so only their traces remain now.

If you walk the path to the center of the ruins passing the Outer and Inner Moats, you will reach the ruins of the Front Gate and Kurogane-mon or the Iron Gate, the entrance of the main portion. These ruins are still surrounded by stone walls of double Masugata system, which you can imagine the main gate had a similar system to it.

Then, go in the hall where you can experience what it looked like in the past. The Large Study Hall was used for public ceremonies which has an impressive large hip-and-gable roof above the front entrance. Visitors enter it not from the front but from the side and walk around the corridors surrounding the rooms. There are eight rooms inside such as Honored Guest Room, Dark Room for storing, and Tiger Room for waiting.

Stone Wall Base for Main Tower with Viewing Spot

The Main Enclosure is the highest point of the castle. The inside of it looked to be a square during the Edo Period, but the Aoyama Shrine, which worships the Aoyama Clan, the last lord family of the castle, has been there since its launch in 1882.

The large stone wall base for the Main Tower is at a corner of the enclosure, which is a good viewing spot of the city area. You can also see a triangle-shaped Takashiroyama-Mountain in the distance, where the ruins of Yagami Castle, which was active in the Sengoku Period, is. The stone wall base had a very small single turret for its scale at the edge during the Edo Period.

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.
