Ozawa married Kazuko Fukuda, the daughter of a wealthy Tanaka supporter. With Kazuko, Ozawa fathered three sons who were raised in Iwate Prefecture. In June 2012, the magazine "Shukan Bunshun" published a letter from Kazuko stating that the couple would divorce, alleging that "Ozawa ran away with his secretaries because of fear of radiation" in the wake of the Fukushima disaster of March 2011.
