Beautiful but Strong Main Tower
It may be a good idea to walk around the inner moat surrounding the main enclosure to enjoy a beautiful view of the tower before entering it. The width of the moat in front of the tower is about 60m. It would make enemies shooting up from the side ineffective but defenders shooting down from the tower more effective at that time. In addition, if the enemies could swim across the moat to the tower, they would be heavily counterattacked by the defenders through its defense systems such as machicolations and loopholes.

Reasons for Black Main Tower
The black-looking Main Tower of Matsumoto Castle (sometimes called “Crow Castle”) is often compared with the Himeji castle’s painted white clearly by contrast. Its black appearance comes from its wooden side walls covered with special Japanese lacquer, which could withstand harsh weathers. Himeji Castle is covered in plaster, which make it look white, and it is newer than Matsumoto Castle. It is said that using plaster on all walls of a castle would not effectively protect against the rain when Matsumoto Castle was built. That meant the improvements in wall painting techniques occurred between the building of the two castles. Another possible reason for the using the black walls is that wooden walls are stronger than plaster walls against the cold winter of inland area like the Matsumoto Basin.

Some also say black was a favorite color of Hideyoshi Toyotomi, while white was the color which Ieyasu Tokugawa often used for his castles when Himeji Castle was built. Anyway, these speculations are enjoyable to see the contrast.

Unique Lookout Tower
The Main Tower of Matsumoto Castle actually consists of the large main tower, the Inui small main tower, and three turrets (Watari Yagura, Tatsumi-Tsuke Yagura and Tsukimi Yagura) which are connected to each other. This is called “multiple attached style”. The large one is generally considered “the Main Tower”. The tower has five levels but six floors inside. This type of the tower is called the lookout tower type, which refers to a small lookout tower on a large turret. In the case of Matsumoto Castle, the turret part is the first and second floors and the fifth and top floors is the tower part, binding the middle part of the third and fourth floors. However, the third floor is built as the attic of the turret part, with no roof. That’s why the numbers of its levels and floors are different.

In addition, the Main Tower has a striking appearance for a lookout tower. One of the reasons for this is that the top floor doesn’t have a veranda, which lookout towers usually had, and is covered with walls. The fact is that it had been first planned to have a veranda, but was changed to its current state during construction. As a result, the tower looks a little top-heavy.

Ako Castle was located on the western edge of Harima Province, facing the Seto Inland Sea, which is now known as Ako City in Hyogo Prefecture. The castle is known as a stage for the Ako Incident, one of the most popular historical events in Japan. It’s also famous for salt industry since salt fields were developed during the Middle Ages. There is little rain in the area.

Naganao Asano renovates Castle
Ako Castle was located on the western edge of Harima Province, facing the Seto Inland Sea, which is now known as Ako City in Hyogo Prefecture. The castle is known as a stage for the Ako Incident, one of the most popular historical events in Japan. It’s also famous for salt industry since salt fields were developed during the Middle Ages. There is little rain in the area.
The range of Harima Province and the location of the castle
It is said that Nagamasa Ikeda, a little brother of Terumasa Ikeda who was the lord of Himeji Castle, first built the castle in 1600 as their branch castle. A branch family of the clan eventually became an independent lord living in the castle as the Ako Domain in 1615. However, the second lord was fired by the Tokugawa Shogunate in 1645 due to his murder from madness. The details of the first stage of the castle are unknown as Naganao Asano, following the castle and domain in the same year, renovated the castle as we know today. He was the lord of a branch family of the Asano Clan which lived in Hiroshima Castle, and was transferred from Kasama Castle. It was very rare to be allowed to renovate castles by the shogunate after 1615 when it defeated the Toyotomi Clan at Osaka Castle and its government became stable.

The renovation was done between 1648 and 1661. The layout of the castle was designed by scholars of military science, Masazumi Kondo and Soko Yamaga. They designed the stone walls of the castle to be bent sophisticatedly to shoot guns at any direction. The Main Enclosure and the Second Enclosure surrounding it were the main portion of the castle, backed by the sea in the south. The Third Enclosure, including the Main Gate, was added to the main portion in the north. These enclosures were divided by water moats on a flat ground, so the castle can be classified a Plain or Sea Castle. The Main Enclosure had the Main Hall for the lord and the stone wall base for the Main Tower, however, the tower was not built on the base.

Naganori Asano causes Ako Incident and is fired
The Ako Incident happened in 1701 when Naganao’s grandson, Naganori Asano (also known as his official position, Takumi-no-kami) was the lord. He was in charge of entertaining the Imperial envoy to the shogun, Tsunayoshi Tokugawa in the Main Hall of Edo Castle, instructed by Yoshihisa Kira (Kozuke-no-suke). On the 14th of March when one of the most important ceremonies would be held, Asano suddenly cut Kira by using a sword at the back, trying to kill him, but failed. Asano was then arrested and ordered by the shogun to kill himself by performing Harakiri on the same day because using swords in the hall was strictly prohibited. Asano was also fired with about 300 retainers and many more of their families. On the other hand, Kira was innocent, as he was just hurt by Asano, by not using swords.

The reason for Asano’s attempted murder was uncertain. Some records suggested that he said he had a grudge against Kira, but he didn’t tell what it was before his death. According to some recent studies, it was thought as the following. It was the second opportunity of entertaining the Imperial envoy for Asano, so he would think he doesn’t need to pay so much for the instruction from Kira, though Asano was rich because of the income from the salt industry. While Kira would need more money for his duty but unfortunately he didn’t have enough of it because he was poor dispite having a higher position. These resulted in Kira might not having instructed Asano and might have criticized him in public. If they are true, who would generally cause such a serious incident? Some, including those at that time, have thought that Asano was going mad.

47 Ronin assaults Kira’s Residence
The retainers of the Ako Domain were very confused to hear about the incident and the following order of opening Ako Castle by the shogunate. They discussed protesting against the shogunate’s decision or simply handing the castle over following the order. Some warriors who served Asano closely never accepted the decision and thought their master must have had a reason. Yoshio Oishi (Kura-no-suke), who was the head of the senior vassals, finally decided to open the castle on the 12th of April. He thought the shogunate might allow Naganori’s brother, Daigaku to follow the domain if they would behave.

Unfortunately, this didn’t happen. The shogunate decided to banish Daigaku to the head family of the Asano Clan at Hirosima Castle. Oishi eventually became the leader of the 47 Ronin under the influence of the hardliners, which attacked Kira’s residence and killed him on the 14th of Dec in 1702 (according to lunar calendar). Oishi left his verbal notice at the site, which says they would do this to complete their master’s work. They were all arrested but it became complicated and cabinet officials of the shogunate discussed how they would treat the Ronin. Some said the Ronin should be executed strictly because they broke the law by assaulting Kira’s residence and killing the innocent man. Some argued that they were real loyal retainers to show a mirror of knighthood. The shogun, Tsunayoshi’s decision was to compromise both opinions to make the Ronin kill themselves by Harakiri. This was the same judgement as their master’s, but very honorable for their positions and actions.

Domain and Castle is followed by Other Clans
Ako Castle and the Ako Domain was followed by the Nagai Clan and the Mori Clan. The Mori Clan governed the area for a long time from 1706 until 1871 when the feudal domain system was abolished. The salt industry of Ako prospered more and the salt fields increased looking like they surrounded the castle. On the other hand, the domain by the Mori Clan faced financial difficulties because they had much less territory than the Asano Clan. For example, the former residence of Oishi in the Third Enclosure was burned down in 1729, but not rebuilt. This was probably because the domain had fewer retainers and budget than before so that they wouldn’t use the residence again.
The southwestern side of the stone wall base of the Main Tower is covered with many diverted stones and some of them are used for its corners. Why did Mitsuhide use them for the important part of the tower?
Features
Main Enclosure as Fukuchiyama Castle Park
Today, the current Fukuchiyama Castle remains as a historical park. The original castle includes the Main, Second and Third Enclosures in a line on a hill. However, the park has only the Main enclosure at the edge of the hill because the Second Enclosure’s part was cut down and turned into residential areas. Therefore, the Fukuchiyama Castle park looks like a castle on a small mountain, which stands out in the city.
The map around the castle
The park has been well developed for visitors so that they can easily walk up on the paved slopes to the top of the hill. You will climb the slope along the remaining stone walls and the restored stone one’s of the Main Enclosure where you can see a diverted stone being used as fillings for the gaps on the wall.

You can access the Main Enclosure by entering the restored Tsurigane-mon or the Hanging Bell Gate after climbing the stone steps or by going on the slope. There is a large well called Toyoiwa-no-i, which is 50m deep and still has 37m deep water.

Main Tower Base uses lots of Diverted Stones
The restored Main Tower is on the original stone wall base which has a complex shape in a plane view because the original tower was extended several times. The entrance of the tower is at the eastern side which has a newer part of the original base.

If you walk around the base to the southern side, you will find the base uses a lot of diverted stones. Diverted stones refer to the stones which had originally been processed and used for other purposes, such as tombstones, stone statues, and stone mills, but were collected and used for rapid castle constructions. Other examples of using them can be seen in castles like Yamato-Koriyama, Matsusaka and Himeji Castles.

You may be surprised to see that the southwestern side of the stone wall base is covered with more diverted stones. The view of the restored Main Tower is good, but you should also check out how the stones are used. The stone wall base was mainly piled using natural stones in a method called Nozura-zumi. The diverted stones in other sides are used to fill gaps between these natural stones. However, the diverted stones at the southwestern side are used to form the corners of the base, the most important part of it. Basically, the corners of stone wall bases must support most of the weight of the tower, even in a case of emergency, such as an earthquake.

What is Mitsuhide’s intention?
For example, in 2016 many earthquakes happened in Kumamoto, the Iidamaru-five-level Turret of Kumamoto Castle was once supported by only one corner stone even though other stones around had collapsed. Around the southern part of the Fukuchiyama Castle’s Main Tower was said to be the oldest, so Mitsuhide Akechi probably built it. Why did he use so many diverted stones and installed them into the important part of the tower?
Iidamaru-five-level-turret and the miracle lone stone walls in July,2016, quoted from the Sankei Photo
One possible reason is purely technical. The diverted stones in the corner are cuboid ones which look like tombs or carved Buddha status. Collecting them might have been useful for Mitsuhide to build the castle efficiently and rapidly. On the other hand, a local tradition says that Mitsuhide’s troops destroyed the temples which were against his orders and took the tomb stones away from them to build the castle. If it is true, using the stones might have meant the new lord showing the conquest and the authority to people. Other historian argued that it must have symbolized the contribution of people to the castle’s construction or taking Buddha’s power in the castle. Overall, only Mitsuhide can answer this question.
Why did Mitsuhide use these diverted stones for the important part of the tower?
So far, about 500 diverted stones were found in the stone walls of the castle or excavated in other places. The excavated ones lie down in vacant spaces in the Main Enclosure.
