Nihonmatsu Castle is a historic castle site located in Nihonmatsu City, Fukushima Prefecture. Also known as "Kasumigajo" or "Shirahata Castle," the site is now maintained as Kasumigajo Park. It is designated as one of Japan's 100 Famous Castles and is characterized as a flatland-mountain castle (hirayamashiki) built at an altitude of 345m on Mt. Shirahata. Today, visitors can explore historical remains such as the stone walls, the reconstructed Minowa Gate, and the castle base (tenshudai), offering a deep look into traditional Japanese fortification structures.
The history of Nihonmatsu Castle dates back to the Muromachi period. It is said that Hatakeyama Takikuni established the first residence in this area around 1341, which led to the naming of the area as Nihonmatsu. Later, in 1414 or 1441, the foundations of the current castle were laid by Nihonmatsu Mitsuyasu. During the Edo period, it served as the residence of the Niwa clan, the lords of the Nihonmatsu Domain. Within the grounds, the "Kaiseki Monument" remains—a stone where the 7th lord of the Niwa clan, Niwa Takahiro, had the principles of domain reform engraved upon the advice of his vassal, Iwaida Sakuhi. This monument was designated as a National Historic Site in 1935. Additionally, the "Seishintei" tea house, a Prefectural Cultural Property, was relocated to the site during the Meiji era and still stands today.
Key features of the castle include the reconstructed Minowa Gate, the recently reconstructed Honmaru Tenshudai (castle base), and the impressive stone walls. At the entrance, you will find the historical Kaiseki Monument. The castle site is well-maintained as a park, allowing visitors to trace the original layout of the castle along the natural terrain. These ruins serve as vital elements for understanding the architectural styles of ancient Japanese fortifications.
Nihonmatsu Castle (Kasumigajo Park) offers different charms throughout the seasons. It is particularly famous for its cherry blossoms, having been selected as one of Japan's 100 Famous Cherry Blossom Spots, making spring a highly recommended time to visit. Additionally, from October to November, the area hosts the Nihonmatsu Chrysanthemum Exhibition, offering a chance to experience local cultural traditions. The castle grounds are open 24 hours a day, allowing for visits at any time.
Visitors can enjoy a historical stroll through the castle ruins, observing the stone walls, gates, and the castle base. The park also features a statue of the Nihonmatsu Boy Scouts, a sculptural piece related to the local history. Walking through the well-maintained park provides a wonderful opportunity to understand the spatial arrangement and structural design of a traditional Japanese castle.
Nihonmatsu Castle is located in the heart of Nihonmatsu City. The site is developed as Kasumigajo Park, and the surrounding area is rich with facilities and local landmarks that reflect the history and culture of the Nihonmatsu region.
The castle site is located on a mountain at an altitude of 345m. To reach the Honmaru (inner sanctum), you must walk from the entrance. Because there are slopes and stone steps, we highly recommend wearing comfortable walking shoes. While the site is open 24 hours a day, please observe general public etiquette and respect the park environment.
