Takaharu was the second son of Goto Tajima no kami Katatoyo (d.1563), whose killing had caused strife within the Rokkaku domain. He submitted to Oda Nobunaga in 1568 and in 1582 sided with Akechi Mitsuhide, who destroyed Oda Nobunaga. After Akechi's defeat, Takaharu found service under Gamô Ujisato.
