Tadazumi is known for his patronage of Ming Dynasty music. He not only invited Gi Shimei, the preeminent Ming music expert of the time, to Himeji in order to study under him, but also made a number of his closest retainers study Ming music under Shimei, and also had Ming-style instruments and costumes made. Following Tadazumi's death in 1772, Ming music continued to be passed down within the Sakai family, but was never again studied and practiced in such a lively manner as during Tadazumi's time.
His other children include:
