Kurobane Castle Ruins Park sits in Ōtawara City, Tochigi Prefecture, preserving the remains of a castle that once served as the seat of the Ōzeki clan during the Edo period (1603-1868). The original castle was constructed in 1576 by Ōzeki Masanaga, though the structures were dismantled during the Meiji era. Today, the park occupies the former castle grounds atop a hill, offering visitors a glimpse into Japan's feudal past through its remaining stone walls, reconstructed gates, and historical markers.

The park holds cultural significance as a testament to the region's samurai heritage. Stone foundations and earthworks reveal the castle's defensive layout, while explanatory signs provide context about the Ōzeki clan's 300-year rule over the domain. The site has been designated as a local historical landmark, and several artifacts excavated from the grounds are displayed in nearby museums. During spring, approximately 200 cherry trees transform the ruins into a popular hanami destination, drawing locals and tourists who come to view the blossoms against the backdrop of ancient fortifications.

Visitors can walk along the preserved moats, climb to the main bailey for panoramic views of the surrounding countryside, and explore the partially reconstructed tower gate that recreates the castle's former entrance. The park includes walking trails that wind through wooded areas where castle buildings once stood, with interpretive panels marking significant locations. A small observation deck at the summit provides views extending to the Nasu mountain range on clear days.

Kurobane Castle Ruins Park is accessible from JR Nasu-Shiobara Station via local bus, with the journey taking approximately 30 minutes. Visitors can take the bus bound for Kurobane and alight at the Kurobane Castle Ruins stop. By car, the park is roughly 20 kilometers northeast of the station with parking available at the base of the hill. Admission is free, making it an economical stop for history enthusiasts and nature lovers exploring the Tochigi region.
