Tone

Tone lies in the mountains of northern Kōzuke, around the upper river of the same name. Numata Castle commanded the district and became a prize in the struggle between the Sanada and Hōjō. Sanada Masayuki captured it in 1580; after Toyotomi Hideyoshi's campaign against the Hōjō in 1590, he gave it to his son Nobuyuki. The Sanada ruled from Numata for five generations before the castle was dismantled on shogunal orders.
