Complete Guide to Shibata Castle: The History and Highlights of Japan’s Only Famous Castle with Three Shachihoko (Mythical Fish-like Charms)
Located in Shibata City, Niigata Prefecture, Shibata Castle is a flatland castle affectionately known locally as “Ayame-jo” (Iris Castle). Selected as one of Japan’s Top 100 Castles, this castle boasts valuable Edo-period castle architecture, including nationally designated Important Cultural Properties. It is unique in Japan for its three-story turret featuring a T-shaped roof adorned with three shachihoko. This article provides a detailed explanation of everything you need to know before visiting Shibata Castle, from its history and architectural charm to its highlights and access methods.
History of Shibata Castle: From the Sengoku Period to the Edo Period
The Era of the Shibata Clan and the Rebellion of Shibata Shigeie
While the origins of Shibata Castle are not entirely clear, it is believed that this site was originally the location of the residence of the Shibata clan, who held enough power to rival Uesugi Kenshin’s father, Nagatamekage, during the Sengoku period.
A significant event in the history of Shibata Castle is the “Shibata Shigeie Rebellion” of 1581 (Tensho 9). Shibata Shigeie, a vassal of the Uesugi clan, rebelled against Uesugi Kagekatsu, the successor to Uesugi Kenshin after Kenshin’s death. This rebellion lasted for seven years, but in 1587 (Tensho 15), Shibata Castle was captured by Uesugi Kagekatsu, and Shibata Shigeie was killed. Afterward, Shibata Castle came under the control of the Uesugi clan.
Construction and Development by the Mizoguchi Clan
The foundation of the current Shibata Castle was laid by Mizoguchi Hidekatsu, the first lord of the Shibata Domain. In 1598 (Keicho 3), by order of Toyotomi Hideyoshi, Mizoguchi Hidekatsu was granted 60,000 koku and entered this territory. The following year, Hidekatsu began a new layout and started the full-scale construction of the castle.
Construction of the castle was a long process, finally completed around 1654 (Shoo 3) during the reign of the third lord, Mizoguchi Nobunao. For approximately 270 years thereafter, until the Meiji Restoration, the Mizoguchi family resided in this castle, and it played a central role in the politics and economy as the administrative center of the Shibata Domain. The Shibata Domain ultimately became a daimyo family with a 100,000 koku (unit of rice production) domain, and it remained so until the Meiji era.
Shibata Castle After the Meiji Restoration
After the Meiji Restoration, while many castles were demolished, Shibata Castle was no exception. Fortunately, the main gate of the inner citadel and the former corner turret of the second citadel escaped demolition, preserving their Edo period appearance to this day. These were designated as important national cultural properties in 1963 (Showa 38).
While some areas of the castle ruins are restricted to the public due to their use as the Japan Ground Self-Defense Force Shibata Garrison, the three-story turret and the Tatsumi turret were restored in 2004, and the site is now known as Shibata Castle Ruins Park, a popular spot for both locals and tourists.
Architectural Features and Structure of Shibata Castle
Location and Layout as a Flatland Castle
Unlike typical mountain castles, Shibata Castle was built on flat land, prioritizing transportation convenience as a political and economic center. The Kajigawa River, flowing through the northern part of the castle, served as the outer moat. The structure centered around the main keep, with the old keep to the north, the second keep to the south, and the third keep further south.
This layout combined defensive and functional design, achieving strong defenses through moats and stone walls despite being a flatland castle. The castle town was also inevitably developed, forming the foundation of Shibata City’s urban structure.
Beautiful Stone Walls and Namako-kabe Walls
The stone walls of Shibata Castle are built using a technique called “kirikomi-hagi.” This is a highly sophisticated stonework technique that emphasizes aesthetics, where stones are precisely processed and stacked so that they interlock seamlessly. This technique gives Shibata Castle’s stone walls a neat and beautiful appearance.
Another distinctive feature is the Namako-kabe wall, with its beautiful contrast of black and white. Namako-kabe is a traditional construction method where flat tiles are laid on the wall surface and the joints are finished with plaster, resulting in excellent fire resistance and durability. The Namako-kabe walls applied to the buildings of Shibata Castle highlight the castle’s prestige and beauty.
Japan’s Only Three-Story Turret with Three Shachihoko (mythical fish-like creatures)
The most distinctive feature of Shibata Castle is its three-story turret, the only one in Japan with a T-shaped roof adorned with three shachihoko. This turret effectively serves as the castle’s keep and is a symbol of Shibata Castle.
Typically, in castle architecture, shachi (mythical fish-like creatures) are placed in pairs at both ends of the main ridge. However, the three-story turret of Shibata Castle has a complex T-shaped roof structure, resulting in shachi on each of its three ridges. This unique design is a rare architectural style found only at Shibata Castle.
The three-story turret, restored in 2004, is located within the grounds of the Japan Self-Defense Forces, so interior viewing is not possible. However, its distinctive exterior can be fully appreciated. turret from the Shibata Castle Ruins Park side is particularly impressive.
National Important Cultural Property: Main Gate and Former Second Bailey Corner Turret
Main Gate of the Main Bailey
The Main Gate of the Main Bailey is a valuable historical structure that retains its Edo period appearance and is designated as a National Important Cultural Property. It is a turret gate in the irimoya (hip-and-gable) style, exhibiting a dignified and imposing presence.
This gate served as the main entrance to Shibata Castle, used for the lord’s entry and exit and for official ceremonies. The black-painted doors and the namako-kabe (sea cucumber wall) design are beautiful, and it well preserves the characteristics of Edo period castle architecture. Passing through the main gate, one can feel the atmosphere of the samurai society of that time.
Former Ninomaru Corner Turret
Another important cultural property is the former Ninomaru Corner Turret. This turret is also a valuable structure that has survived from the Edo period and has a two-story turret design.
Corner turrets played an important role in the defense of the castle, functioning as lookout and defensive bases. The former Ninomaru Corner Turret is an important historical document that conveys the architectural technology and defensive philosophy of the time. Along with the main gate, it has extremely high historical value as the only surviving examples of Edo period castle architecture in Niigata Prefecture.
Restored Tatsumi Turret
The Tatsumi Turret, along with the three-story turret, was restored in 2004. The Tatsumi Turret was named as such because it was located southeast (in the Tatsumi direction) of the main keep.
The restored Tatsumi Turret, while not as large as the three-story turret, is an important structure for understanding the defensive system of Shibata Castle. The restoration was faithfully based on historical documents and drawings, providing clues to imagining the appearance of Shibata Castle during the Edo period.
Although the Tatsumi Turret is located within the Self-Defense Forces’ grounds and therefore cannot be viewed from the inside, its exterior can be enjoyed from the park.
Seasonal Charms of Shibata Castle Ruins Park
Spring: A Famous Cherry Blossom Spot
Shibata Castle Ruins Park is known as a representative castle cherry blossom spot in Shibata City. In spring, approximately 300 Somei Yoshino cherry trees planted around the grounds bloom simultaneously, captivating visitors.
The contrast between the white walls and black plasterwork of the castle architecture and the pale pink cherry blossoms creates a spectacular view, attracting many visitors for cherry blossom viewing. The cherry trees in front of the main gate and along the moat are particularly popular photo spots. The trees are also illuminated at night, allowing visitors to enjoy the magical sight of cherry blossoms after dark.
The best time to see the cherry blossoms is usually from early to mid-April, and events such as the “Shibata Castle Ruins Park Cherry Blossom Festival” are held during this period.
Summer: Harmony of Fresh Greenery and the Castle
In summer, Shibata Castle Ruins Park is enveloped in lush greenery. The contrast between the white walls of the castle architecture and the fresh green leaves is beautiful, offering a refreshing landscape. The reflection of the turrets on the moat’s surface is also cool and refreshing, making it an ideal season for a stroll.
Autumn: Autumn Leaves and Historic Buildings
In autumn, the trees in the park change color, and the combination of autumn leaves and the castle architecture creates a deeply evocative scene. The ginkgo and maple trees turn yellow and red, creating a magnificent contrast with the stone walls and white facades.
Winter: Shibata Castle Covered in Snow
Niigata Prefecture experiences heavy snowfall in winter, and Shibata Castle is also covered in snow. The sight of the castle completely covered in pure white snow is like a beautiful ink painting. In particular, the three shachi (mythical fish-like creatures) on the three-story turret, topped with snow, have a unique charm that cannot be seen anywhere else.
