Kuroiso was located at the northernmost tip of Tochigi, bordering Fukushima Prefecture. The city's train station, Kuroiso Station, served as the terminal station for two subsections of the JR East Tōhoku Main Line railway, making it a junction between the Kantō and Tōhoku regions of Japan. The station's bus terminal also made Kuroiso a gateway to the neighboring town of Nasu, known in Japan for its mountain hot springs and as the location of the Nasu Imperial Villa.
In the area, Kuroiso was popular for its local cafes and restaurants, as well as for having northern Tochigi's only multiplex movie theater.
A Bridgestone steel cord plant was also located in the city.
