Complete Guide to Fukui Castle Ruins | The Famous 680,000-Koku Castle Built by Yuki Hideyasu and its Remaining Historical Heritage
Located in the heart of Fukui City, just a 3-minute walk from Fukui Station, Fukui Castle Ruins is one of the most famous castles in the Hokuriku region, built in 1606 by Yuki Hideyasu, the second son of Tokugawa Ieyasu and the first lord of the Fukui Domain. This castle, which served as the stage for the prosperity of the Echizen Matsudaira family for approximately 270 years, now boasts a rare example of history and modernity coexisting, with the Fukui Prefectural Government and Prefectural Police Headquarters standing on its site.
History of Fukui Castle | Built by Yuki Hideyasu, the Second Son of Tokugawa Ieyasu
Yuki Hideyasu and the Circumstances of Fukui Castle’s Construction
Yuki Hideyasu was a warrior with an unusual background, born as the second son of Tokugawa Ieyasu, but adopted by Toyotomi Hideyoshi, and later inheriting the Yuki family. In 1601, after the Battle of Sekigahara, Ieyasu granted Hideyasu Kitano-sho in Echizen Province with a domain of 680,000 koku, entrusting him with a strategic location in the Hokuriku region.
Hideyasu began renovating the castle in 1601 and completed its full construction in 1606. Various daimyo of the Hokuriku region were ordered to assist in the construction, and surrounding daimyo, including the Maeda family of Kaga, participated in the project. The domain’s 680,000 koku was the second largest in Japan at the time, after the Kaga Domain, and a magnificent castle befitting its grandeur was constructed.
From Kitano-sho to Fukui | The Origin of the Place Name: “Fuku-no-i”
Originally called “Kitano-sho,” this area was renamed “Fukui” and then “Fukui” during the time of the second lord, Matsudaira Tadanao, because the character “Kita” (north) was considered unlucky as it sounded like “defeat.”
A well called “Fuku-no-i” (Fortune Well) still remains at the base of the castle keep, and it is said that this well is the origin of the name Fukui. Fuku-no-i is an important water source within the castle grounds and is carefully preserved as a symbol of the city’s identity.
The Magnificent Appearance at the Time of Construction | A 37-meter-tall, Four-Story, Five-Tiered Castle Keep
At the time of its construction, Fukui Castle was a magnificent castle boasting a 37-meter-tall, four-story, five-tiered castle keep. The main keep was surrounded by the second and third baileys, creating a vast castle complex covering approximately 480,000 square meters.
The castle keep was destroyed in a great fire in 1669 and was never rebuilt. However, defensive structures such as stone walls, moats, and turrets were maintained, and the castle continued to function as the residence of 17 generations of the Echizen Matsudaira family for approximately 270 years.
Highlights of Fukui Castle Ruins | Shakudani Stone Walls and Historical Remains
Magnificent Stone Walls Built with Shakudani Stone
The greatest highlight of Fukui Castle Ruins is the stone walls built with Shakudani stone, quarried from Mt. Asuwa near the castle town. Shakudani stone is a bluish-green tuff unique to Fukui, characterized by its ease of processing and beautiful color.
The remaining stone walls of the main keep are approximately 4.5m high and extend for approximately 600m, demonstrating the high level of technology at the time of construction. In particular, the transitional techniques from “nozurazumi” (rough-stone masonry) to “uchikomi-tsugi” (fitted stone masonry) can be seen, making it a fascinating remains for stone wall enthusiasts.
Some parts of the stone walls bear markings, allowing us to confirm the traces of the various daimyo who participated in the castle’s construction. These markings are attracting attention as valuable historical materials that reveal the reality of the system of daimyo assisting in the castle’s construction.
Castle Tower Base and “Fuku-no-i” Well
The castle tower base remains in excellent condition at the site of the main keep. Climbing to the base, one can imagine the former appearance of the 37-meter-tall castle tower. Currently, it has been developed as an observation space, offering a superb view of Fukui city.
Next to the castle tower base is the aforementioned “Fuku-no-i” well. Archaeological excavations have revealed that a hole just wide enough for one person to pass through, constructed of cut stones, extended from this well to another well discovered below the castle tower base. This is believed to have been a secret water source route during sieges.
Gohonjo Bridge and Inner Moat
The “Gohonjo Bridge” spans the entrance to the main keep. While the current bridge is a reconstruction, it is an important structure that evokes the former path to the castle. The inner moat remains beneath the bridge, offering a beautiful view of cherry blossoms reflected on the water in spring.
Although part of the inner moat has been filled in, approximately 400 meters of the moat remains around the main keep, preserving its original appearance. The moat still has abundant water, creating a refreshing space of water and greenery despite being in the heart of the city.
Yamasatoguchi Gate and Toneri Gate
Several gates were located within the main keep, and their foundation stones and gate remains can now be seen. The Yamasatoguchi Gate site, in particular, is preserved as an important relic that demonstrates the scale of the castle at the time.
Near the Toneri Gate site, there is a point where you can observe differences in the construction methods of the stone walls from that era, allowing you to learn about the evolution of castle architecture.

After the Meiji Restoration, Fukui Castle was abandoned, and many of its buildings were demolished. During the Meiji era, the Fukui Prefectural Office was built on the site of the main keep, and it has continued to function as the central hub of Fukui Prefecture’s administration ever since. The unique landscape, where historical remains and modern administrative facilities coexist, is a distinctive charm of the Fukui Castle site.
