In 1724, the tairōYanagisawa Yoshiyasu arranged for a 10,000 koku holding in Echigo Province to be assigned to his 4th son, Yanagisawa Tsunetaka. This marked the start of Kurosawa Domain. Although the Yanagisawa clan remained in control until the Meiji restoration, they preferred to reside in Edo and rely on the collection of revenues as absentee landlords. The finances of the domain were perpetually in a state of bankruptcy, partly caused by the fact that much of the domain was mountains and forests and unsuitable for rice farming. The actual revenues of the domain often fell short of 10,000 koku and the domain was forced to resort to frequent loans from the parent house of the Yanagisawa clan in Yamato-Kōriyama for financial assistance. By 1843, the domain was over 5000 ryō in debt. The 7th daimyō, Yanagisawa Mitsuteru, was the first daimyō to actually visit the domain.
