The design of the current Main Tower is very different from the original one which had simple roofs. The current tower apparently has many decorations like large hip-and-gables, which the original one didn’t have.
Features
Castle is near Kokura Station
Today, the current Kokura Castle is near Kokura Station, only about a 15 minute walk away from the station. Unfortunately, you can’t see the castle from the station because of the high buildings around. If you first reach a side of Murasaki River and walk on the promenade alongside it for a while, you can see the Main Tower of the castle among the buildings. This is the moment when you can understand the castle was developed together with the rivers.
The map around the castle
The main portion of the castle, including the tower, has been developed as Katsuyama Park. It was once surrounded and divided by many water moats, so there were few gates and bridges such as Tora-no-mon Gate and Nishi-no-mon Gate. However, few of the moats remain, so that’s why visitors can easily access the park now. For example, if you walk from the river to the park by passing the Kitakyushu City Hall beside Otesaki-mon Gate Ruins, you can get close to the Main Tower soon.
Current Main Tower is apparently very different from Original Tower
The current Main Tower, which was reconstructed in 1959, is 28.7m high, 5.9m higher than the original one. It is also the sixth tallest existing Main Tower in Japan. The total height including the original stone walls is 47.5m. If you stand by the inner moat surrounding the tower and the walls, they look really great; it is certainly a good viewing spot of the castle. However, there is a controversial issue about the tower. The design of the current Main Tower is very different from the original one which had simple roofs. The current tower apparently has many decorations like large hip-and-gables, Chinese styled gables and triangular shaped gables, which the original one didn’t have. It is said that the designer of the current one tried to build a tower with the same design as the original one but he couldn’t. That was because the sponsor requested him to use the current design. People at that time wanted a showy symbol which could attract many visitors.
Several Gate Ruins of Main Enclosure
To enter the Main Tower, you have to go to the main enclosure by passing the great stone walls of the Main Gate Ruins. The walls have some huge ornamental stones and form a defensive square called Masugata.
After that, you only need to walk up a gentle slope to reach the enclosure and the tower. However, in the past, high-class warriors went through another gate called Keyaki-mon which remains as ruins. Meanwhile, low-class warriors had to enter Kurogane-mon Gate instead. These came from a clear discrimination of how to get the castle even among the warriors.
In the main enclosure, there was the main hall and there are the ruins of the Imperial Japanese army’s 12th division headquarters.
Renewed Interior of Main Tower
The Main Tower is used as a historical museum whose interior was recently renewed in 2019. Its top floor is used as an observation platform like the original one used to be. The appearance of the floor was also restored hanging out in the Nanban (Western) style, so its interior was built being wrapped in by the outer part.
The restored three-level Main Tower is on the corner of the stone walls of the main enclosure, which looks really great! Not only is it a symbol of the castle but also of the city. It could also had been seen as the authority of the lord as well as a threat to enemies when the original tower was there.
Later History
After the Meiji Restoration, Kuniori Katakura, the last lord of the castle moved to Hokkaido with his some retainers. All the castle buildings and stone walls were demolished and sold to earn their expenses. The vacant castle ruins were turned into Masuoka Park which has became famous for cherry blossoms for some time. In 1987, a NHK drama called “Dokuganryu (one-eyed hero) Masamune” aired and became very popular. The drama featured not only Masamune Date but also the Katakura Clan, so many visitors visited the Shiroishi Castle Ruins but were disappointed at the ruins with few historical items. The mayor of the city saw the situation and decided to restore the castle in 1988.
One of the most important topics about it was that the castle would be restored using the traditional wooden construction. However, there was a big problem with the law. The original Main Tower was 16.7m high. Meanwhile, Japan’s Building Standard Act basically doesn’t allow builders to build wooden buildings which are over 13m tall. According to this law, the tower would not be able to be built. After that, The city negotiated with the central government, and finally got an exemption by the competent minster to build the tower at its original height. The restoration was completed in 1997.

Many Historical Items in Main Enclosure
Today, the Shiroishi city area still has a traditional atmosphere of Shiroishi Castle and its castle town. This is probably because the Main Tower was restored on the hill and the old waterways are still intact in the city area. There were several enclosures on the hill in the past, but they were turned into shrines, parks, and playgrounds, excluding the main enclosure with the restored items.
That’s why most visitors go to the main enclosure by walking on the eastern or northern slopes on the hill. If you take the eastern one, you will see the few remaining original stone walls at the base of the enclosure. The other stones above were all demolished and sold during the early Meiji Era. You will next see the restored stone walls which were piled up using natural large stones in Nozura-zumi method. They look mild rather than wild as most of the stones were round-shaped.

Well restored Main Tower and Main Gate
The restored three-level Main Tower is on the corner of the stone walls, which looks really great! Not only is it a symbol of the castle but also of the city. It could also had been seen as the authority of the lord as well as a threat to enemies when the original tower was there. In fact, there were three-generation towers on the walls during the Edo Period, which meant it had been rebuilt twice, according to the excavations. The current tower was restored on the second stone foundations because they remain in the best conditions. In addition, the appearance of the tower came from the third generation which was drawn in some pictures. The second and third ones are probably almost the same or similar since the third one was restored in 1823 after the second one burned in 1819.
The main gate of the enclosure was also restored at the same time as the Main Tower. The gate consists of two gates and stone walls, which form a defensive space called Masugata. The Masugata systems in other castles are usually a square and closed space but that of Shiroishi Castle is very unique. The first gate is always open with no doors (according to the excavations so far) and the space inside is half occupied by a corner of the stone walls of the enclosure. Visitors can’t clearly see the inside, because it is blocked by the walls. That may be the reason for the first gate having no doors.
Other Ruins in Main Enclosure
The inside of the main enclosure is empty with the signboard of the Main Hall which was built there. The other sides of the enclosure look like earthen walls which remained after the covering stone walls had been removed. There are the Back Gate Ruins on the opposite side of the Main Gate. There are also the ruins of Tatumi (southeastern) Turret and Hitsujisaru (southwestern) Turret at other corners of the enclosure.
Each independent lord was not allowed to have castles, excluding the only one the lord lived in, by the shogunate. However, Shiroishi Castle, where the Katakura Clan as a retainer lived in, remained as an exemption. This was probably due to Date’s strong influence as well as Katakura’s contributions.
Location and History
Castle owned by Katakura Clan, Senior Vassal of Date Clan
Shiroishi Castle is located in modern day Shiroishi City at the southern edge of Miyagi Prefecture. It was also located in the southern edge of the Date Clan’s territory during the Edo Period. The lords of the clan had the area around the castle being governed by their trusted senior vassal family, the Katakura Clan all through the period. The castle had a three level turret called the Large Turret which was actually equivalent to the Main Tower. That’s why the castle looked like a symbol of an independent lord.
The range of MIyagi Prefecture, the range of the Sendai Domain was larger than the prefecture
The founder of the Katakura Clan, Kagetsuna Katakura served his master, Masamune Date from his childhood because Kagetsuna’s older sister, Kita became Masamune’s foster mother. Since then, Kagetsuna contributed to Masamune becoming the greatest warlord in the Tohoku Region during the late 16th Century by joining many battles and being a diplomatic agent with other warlords. When the ruler, Hideyoshi Toyotomi invaded the Kanto Region to complete his unification of Japan in 1590, Masamune was wondering if he should follow Hideyoshi or not. Kagetsuna advised Masamune to do so, and as a result, they were able to survive. Masamune eventually gave Kagetsuna the important Shiroishi area in 1602 after the Date Clan’s territory was fixed as the Sendai Domain by the Tokugawa Shogunate.
Kagetsuna’s son, Shigenaga was very active in the summer campaign of the Siege of Osaka in 1615 where the shogunate defeated the Toyotomi Clan. There is a heroic story about him and his rival, Nobushige Sanada. They once fought each other in the battle, but Nobushige sent a letter (affixed to an arrow) to Shigenaga, which asked him to accommodate Nobushige’s children before his death. Kagetsuna accepted it, and then, Oume, Nobushige’s daughter would be Shigenaga’s second wife and another son, Daihachi would be a retainer of the Sendai Domain. One theory seems to be that Shigenaga took Oume away from Osaka Castle when it was falling and accommodated the other children when they later visited her in Shiroishi Castle. In either case, Shigenaga must have been a man of great capacity.
Castle survives as exemption of One Castle per Province
Shigenaga’s successor, Kagenaga was also important for the domain. When an internal trouble of the Date Clan, called Date-sodo (feud), happened in 1671, the government of the domain got out of control due to a bloody affair at the shogunate court in Edo. Kagenaga stayed local to keep other retainers calm and kept the government. These events were decisive for the position of the Katakura Clan. In addition, each independent lord was not allowed to have castles, excluding the only one the lord lived in, by the shogunate. However, Shiroishi Castle, where the Katakura Clan as a retainer lived in, remained as an exemption. This was probably due to Date’s strong influence as well as Katakura’s contributions.
Castle is completed by Gamo and Katakura Clans
As for Shiroishi Castle itself, it is uncertain when it was first built, but it was considered an important strategic location for transportation. After the unification of Japan by Hideyoshi Toyotomi, Satonari Gamo, a senior vassal of the clan owned and modernized the castle by building stone walls and the Main Tower. He would later improve several other castles like Kasama Castle, which can be seen as a hidden master of castle constructions. The Katakura Clan lived and improved the castle more based on the essential structures Satonari built.
The castle had several enclosures on a hill. The Main Enclosure on the top had the main buildings of the castle, such as the three-level Main Tower, Main Gate, Back Gate, Main Hall, and two two-level turrets. They were exactly the same items as what other independent lords had. However, the Main Hall also had an interesting feature. The hall had two front entrances, one for locals and the other only for the lord of the Date Clan, the master of the Katakura Clan. The hall also had the rooms, called Onari-goten, where only the lord could stay.
The Katakura Clan also developed the castle town below the hill, where the retainers and other citizens lived in. Waterways were also developed in the town for defensive purposes and living. For example, there were Samurai residences in the Third Enclosure, part of the town, which was surrounded by the Sawabata River and the waterways. The residences were relatively smaller than other residences of independent domains. This was because the retainers under the Katakura Clan had lower incomes than those who served independent lords.
One of stages of Meiji Restoration
In 1868 during the Meiji Restoration, an important event happened to the castle again. Many domains against the New Government in the Tohoku Region held the Shiroishi Meeting in the castle. This was because the Sendai Domain was their leader and the castle could also be a hub for them. This event would be the trigger for the Boshin War between the government and the domains. However, the castle was eventually opened as its real master, the Sendai Domain had surrendered to the government.
