The ruins of Nihonmatsu Castle, officially known as Kasumiga Castle Park, are a historically significant site dating back to 1414. Although the original castle buildings were destroyed during the Boshin War in 1868, the site remains one of Japan's '100 Beautiful Castles' and offers a compelling glimpse into feudal Japan. It's particularly noted for its reconstructed gates, extensive stone walls, and the poignant statues commemorating the young boys who fought in the Boshin War.
Visitors consistently praise the park's natural beauty and the expansive, well-maintained grounds. Many highlight the stunning views from the top, especially of the surrounding mountains like Adatara and Azuma. The site is particularly popular during seasonal events; the cherry blossoms in mid-April draw large crowds, and the Chrysanthemum Dolls Festival, held annually from October to November, is frequently described as a unique and beautiful experience, showcasing intricate chrysanthemum displays and traditional Japanese culture. Reviewers often mention the peaceful atmosphere, making it an ideal spot for a leisurely walk or relaxation.
For a fulfilling visit, allocate at least 2-3 hours to explore the extensive grounds. While some areas are flat, many paths are steep, offering a good cardio workout, as noted by several visitors. Comfortable walking shoes are highly recommended. If visiting during peak seasons like cherry blossom or chrysanthemum festivals, expect larger crowds. Reviewers suggest that driving to the top of the castle is an option, which can save time and effort compared to parking at the bottom and walking up the steep Kubocho-zaka slope. Free parking is available, especially during the Chrysanthemum Dolls Festival.
The ruins are accessible from Nihonmatsu Station. While some sources suggest a 20-minute walk, visitors consistently report that the ascent, particularly the Kubocho-zaka slope, makes it closer to a 30-minute walk. For those driving, there is parking available, and some reviewers mention being able to drive directly to the top of the castle grounds, which can be convenient for those with mobility concerns or limited time. Look for signs to Kasumiga Castle Park.
A common point of clarification from visitors is that despite its name, there is no actual castle tower, only ruins and reconstructed elements. Those expecting a fully preserved castle might be disappointed. However, understanding that it is a ruin allows visitors to appreciate the historical foundations, impressive stone walls, and the park-like atmosphere. The historical plaques, available in both Japanese and English, help provide context and enhance the experience.
