Yeah, yamada-san's right. Fuji is the vehicle for right-leaning Sankei. NHK is the voice of the government, regardless of what it claims it is ("neutral public service" so they say). TV Asahi is cohort of left-leaning "liberal" Asahi Shimbun, and NTV associated with anti-communist Yomiuri. TBS is supposedly middle-of-the-road with Mainichi Shimbun, though it's not always true.
You have to filter media reports with understanding of their respective backgrounds.
