Nothing states that. I think you may be confused by the whole Yin/Yang Kurama thing. While Minato did split the Nine-Tails' chakra in two halves, one called Yin and the other Yang, we're talking about chakra here, not nature. Yang-Kurama doesn't have Yang Release, and Yin-Kurama doesn't have Yin Release as well.
