TV Asahi has special commitments to her but they are not so cozy with the JSF like Fuji TV. Some of the JSF people might have been irritated by TV Asahi's blatant promotion of Ando. It's reported that TV Asahi (which bought the broadcast rights of Nebelhorn) had urged the ISU (German federation) to give an invitation without knowledge of the JSF.
