Shocking remarks like "there was no Nanjing Massacre" and "the gender equality law triggered Japan's low birthrate" by NHK governors appointed by Prime Minister Shinzo Abe have called into question the qualifications and neutrality of the public broadcaster's board and the biased way its members are selected.

Japan's equivalent of the BBC has been under fire since last month, when Chairman Katsuto Momii said every country had an institutionalized wartime brothel program similar to Japan's massive "comfort women" system.

The remark raised questions about NHK's ability to deliver fair and unbiased news.
