History of Ushiki Castle | From the Sengoku Period to the Edo Period
Construction and Early History
While there are no clear records regarding the construction period of Ushiki Castle, it is believed to have been built during the Sengoku period as a base for controlling the southern part of Awa Province. Built on a hilly area known as Shiroyama, this castle was strategically located overlooking the town of Tomioka.
The Invasion of Shinkai Saneshige and the Chosokabe Clan
During the Tensho era (1573-1592), Ushiki Castle was ruled by Shinkai Saneshige. However, around 1582, the situation changed dramatically with the invasion of Awa Province by Chosokabe Motochika, a Sengoku daimyo of Tosa Province.
As Chosokabe Motochika advanced his conquest of Awa Province, he positioned Ushiki Castle as a crucial stronghold. Shinkai Saneshige surrendered to the Chosokabe clan, and the castle subsequently came under their control.
The Era of Kosokabe Chikataka
Under the Chosokabe clan’s rule, Kosokabe Chikataka was appointed as the lord of Ushiki Castle. The Kōsokabe clan was a branch of the Chōsokabe clan and was entrusted with governing southern Awa Province. It is believed that Chikayasu used Kaifu Castle (present-day Kaiyō Town) as his base, while also utilizing Ushiki Castle as an important subsidiary castle.
However, Kōsokabe Chikayasu met a tragic end in 1585, when he was assassinated on the orders of Chōsokabe Motochika. This incident is considered part of an internal power struggle within the Chōsokabe clan and significantly impacted the governing structure of southern Awa Province.
Positioning as one of the Nine Castles of Awa
Ushiki Castle was counted as one of the Nine Castles of Awa. The Nine Castles of Awa refer to nine castles considered particularly important within the Tokushima Domain. These castles were strategically positioned as key points in the domain’s defense system.
The Edo Period and Abandonment
During the Edo period, it came under the control of the Hachisuka family of the Tokushima Domain, and the domain’s chief retainers and castle lords were appointed. According to records, a man named Masayoshi served as the castle lord.
However, with the Edo period’s “One Castle Per Province” decree and the arrival of a peaceful era, the military importance of Ushiki Castle gradually declined. While the exact date of its abandonment is unknown, it is believed to have lost its function as a castle by the mid-Edo period.
Origins of Alternative Names | Tomioka Castle and Ukiki Castle
Ushiki Castle has two alternative names, each with an interesting origin.
Tomioka Castle
The alternative name Tomioka Castle originates from Tomioka Town, the name of the area where the castle is located. It is thought that this name was more familiar to the local residents.
Ukiki Castle
The alternative name Ukiki Castle has a beautiful origin. When Tomioka Town is covered in fog, the gourd-shaped castle ruins appear to float like a turtle, hence the name. The name “Ukiki” (浮亀) can be considered a poetic expression born from the castle’s topographical features and a natural phenomenon.
This phenomenon can still be observed today if weather conditions are right, and during seasons when early morning fog is common, you might be able to enjoy a fantastical landscape from around the castle ruins park.
Structure and Remains of Ushiki Castle
Former Castle Structure
Ushiki Castle was built as a flatland castle, skillfully utilizing the topography of the hilly area known as Shiroyama. This castle, with its gourd-shaped topography, is presumed to have had a structure with multiple baileys (kuruwa).
As a castle from the Sengoku period (Warring States period), it is believed to have had the following defensive structures:
- Honmaru: The central part of the castle, the lord’s residence
- Ninokuruwa & Sannomaru: Residences of retainers and troop encampments
- Horikiri: A defensive structure cutting across a ridge
- Dorui: A defensive wall made of piled-up earth
- Koguchi: Castle gate or entrance
Current Status of Remains
Unfortunately, due to residential development since the Meiji era, most of the remains of Ushiki Castle have been lost. Currently, the southern half of the original castle hill, which barely remains, is preserved as Ushiki Castle Ruins Park.
While clear remains such as stone walls and moats cannot be confirmed, some parts of the park’s topography still retain a slight trace of its former appearance. History enthusiasts may enjoy comparing the current topography with old records and imagining the castle’s former appearance.
