Among the six Tohoku prefectures' proud castles: Tsuruga Castle, the pride of Aizu, which held off large armies during the Boshin War (Aizuwakamatsu City, Fukushima Prefecture)

During the Boshin War of the Meiji Restoration, the feudal domains in Fukushima Prefecture fought fiercely against the Meiji government forces (Imperial Army) as part of the Oshu-Uetsu Alliance Army, and many castles were damaged in the fighting that ensued

Aizu's Tsuruga Castlewas also attacked by a large army of government forces, resulting in a siege. Although it suffered significant damage from artillery fire, the castle never fell.

By the way, the term "territory" in the context of a castle does not mean the "territory" of an animal or anti-social forces, but refers to the overall design of the castle (the layout of the moats, stone walls, earthen ramparts, moats, and trenches, etc.)

Also known as Aizu-Wakamatsu Castle, Wakamatsu Castle, Kurokawa Castle, and Aizu Castle, this castle, which once served as the administrative center of the Aizu Domain,Tsuruga Castle Ruinsis now designated as a national historic site as

During the Boshin War, the Aizu Domain secured a force of approximately 9,400 men by recruiting not only samurai but also the daughters of samurai, such as the "Byakkotai" (CorpsFujotai" (Women's Corps), as well as townspeople and farmers. However, this was a desperate disparity in numbers against the 75,000-strong New Government Army.

However, during the month-long siege, the Aizu clan fought bravely as one, and although the castle tower and other structures were half-destroyed, the castle did not fall until it was finally surrendered and opened up

Naomori, the seventh head of the Ashina clan, built Higashi Kurokawa Castle in an area that was then called Kurokawa, and this is said to be the predecessor of Kurokawa Castle

During the reign of the 16th lord, Moriuji, the domain expanded to its greatest extent, bringing the entire Aizu region under its control, and it flourished to the point that many cultural figures visited

However, in 1589 (Tensho 17), the 20th head of the clan, Yoshihiro, was defeated by Date Masamune at Suriagehara at the foot of Mount Bandai, and Yoshihiro fled to Hitachi, where Kurokawa Castle came under the control of Date Masamune

Two years before the Battle of Suriagehara, in 1587 (Tensho 15), Toyotomi Hideyoshi, who had almost unified Japan,General Peace Edictissued

As a result, Masamune's invasion of Aizu incurred Hideyoshi's wrath, and Masamune went to Hideyoshi, who was on a campaign to conquer Odawara, to express his intention to surrender. Hideyoshi accepted his offer and transferred him to Iwateyama Castle

In 1593 (Bunroku 2), the castle tower, described as a "seven-story watchtower type," was completed, and the castle was renamed "Tsuruga Castle" after the Gamo family's crane crest, becoming the foundation for the development of Aizu-Wakamatsu.

Uesugi clan (1598-1601)

In 1589, when Ujisato died at the age of 40, internal conflict arose within the Gamo family, and Hideyoshi orderedUesugi Kagekatsuto be transferred from Echigo to Aizu, making him a powerful daimyo with a domain of 1.2 million koku.

After Hideyoshi's death, Kagekatsu became one of the Five Elders of the Toyotomi government, but his conflict with Tokugawa Ieyasu deepened within the Toyotomi government, leading to Ieyasu's conquest of Aizu and the Battle of Sekigahara

The Battle of Sekigahara ended in one day with the victory of the Eastern Army, and Uesugi Kagekatsu, who had allied with Ishida Mitsunari of the Western Army, was transferred from Aizu, with a fief of 1.2 million koku, to Yonezawa, with a fief of 300,000 koku, in just three years

Gamo clan (1601-1627)

Rinkaku
During Hidesato's time, the teahouse "Rinkaku" was built for Sen no Rikyu, who was hiding there, and is the only remaining building from that time

The Gamo clan was transferred to Aizu again, and Ujisato's eldest son, Hideyuki, entered Tsuruga Castle

However, Hideyuki died at the age of just 30, possibly due to the stress caused by the extensive damage caused by the Great Aizu Earthquake that occurred around that time

Due to internal strife within the Gamo family over succession, they were transferred to Matsuyama in Iyo Province, andKato Yoshiaki, took over the position.

Kato clan (1627-1643)

the "Seven Spears of Shizugatake," was also a master castle builder. He spearheaded the layout of Tsuruga Castle and the development of the territory, and after his death, his eldest son, Akinari, took over.

The current appearance of Tsuruga Castle was mostly created during this period, with the castle tower being renovated to its current five-story structure, the Kitaidemaru and Nishiidemaru extensions being added, and the main entrance, which had previously been on the east side, being moved to the north

However, a family dispute arose within the Kato clan between Akinari and the chief retainer, Hori Shusuke, and the Tokugawa shogunate intervened, resulting in Akinari's confiscation of Aizu

Masayuki established the "Fifteen Articles of Family Precepts," forcing his family to swear absolute loyalty to the Tokugawa shogunate for generations to come, and it is said that this was a contributing factor to the Boshin War.

The Hoshina clan changed their surname to Matsudaira during the reign of the third feudal lord, Masakata, and served the shogunate as a related clan, continuing through the last castle lord, the ninth feudal lord, Katamori


The majestic Tsuruga Castle is revived today

Tsuruga Castle
The rebuilt castle tower had black roofing tiles, but in March 2011 it was restored to the red roofing tiles it had before it was demolished

After the Meiji Restoration, the castle was designated to remain in accordance with the "Regulations for the Abolition of Castles," but it was dismantled, with the exception of some parts such as the stone walls and trees, as well as the keep. In 1908 (Meiji 41), an army training ground was established on the east side of the third bailey, so approximately 6 hectares of the third bailey, including the moat and earthworks, were removed.

However, parts of the Honmaru, Ninomaru, Sannomaru, Kitaidemaru, Nishiidemaru and the moats surrounding them remain, allowing us to see the layout of Tsuruga Castle during the Boshin War

Then, in 1965, the castle tower was reconstructed using reinforced concrete to restore its exterior, and in 1990, theRinkaku(a designated important cultural property of Fukushima Prefecture), which had been moved outside the castle grounds, was relocated and restored to its original location within the main enclosure, thus restoring its former grandeur.


Consideration of Tsuruga Castle's territory

To the east of the main keep of Wakamatsu Castle are the vast second bailey, the ambush bailey, and the third bailey, which are capable of accommodating a large number of defenders. Outworks are built to the west and north of the main keep, anda belt-shaped bailey(obigurwa) is constructed extending from these outworks to the main keep.

Ushinuma, located directly below the high stone wall, is considered to be a wide inner moat, and further south of that is Yukawa, which serves as an outer moat

Nishidemaru

Originally, the Nishidemaru (western outwork) of the Umadashi (horse outwork) was located at a lower elevation than the plateau where the main keep was situated. If the Nishidemaru fell, the defenders of the outer baileyUmezaka (Plum Hillfrom their higher positionreverse descentcould repel

Inner Sanuki Gate

However, to capture Nishidemaru in the first place would require either penetrating the narrowgatesof the "Nishi Otemon" or "Uchi Sanuki Gate," which are under a hail of bullets and arrows, or crossing the wide "Minamimachi-dori Moat" and climbing the high stone walls, all of which would result in heavy losses.

Kitademaru

Like the Nishidemaru, this was originally a barbican thatKato Akinariexpanded into the Kitademaru. The Otemon gate, which was originally located on the east side of the castle, was later moved to this Kitademaru.

Yokote Hill

This area is also at a difference in elevation from the main keep, and even if you capture the northern outwork andYokote-zakaclimb the slope known asTaiko-mon" gate.

Koromaru

The main gate of Kitademaru, which served as the castle's main entrance, was a focal point of fire not only from the outer bailey, main enclosure, outer bailey, and watchtower, but also from the adjacent Nishidemaru, earning it the nickname "Minagoroshimaru" (meaning "massacre bailey").

Ninomaru and Sannomaru

Corridor Bridge

Even if you are lucky enough to cross the Corridor Bridge, you will have to go through this narrow gate to attack the main castle

Furthermore, if the second bailey were to fall, the wooden bridge between it and the main bailey, known as the "corridor bridge," would be destroyed, and the main bailey would be protected by high stone walls, turrets, and flanking fire positions.
