I'm actually of the theory that Amaterasu itself is Blaze Release (even though it was said to be the highest form of Fire Release, so dunno how that fits in) but it doesn't make sense that an advanced nature just manipulates ordinary Fire Release. One would think that Amaterasu was already a Blaze Release and Kagutsuchi are variations.
