A denial of Japan's wartime atrocities by NHK executives has sparked widespread fear among international media that the public broadcaster is losing its independence and becoming the mouthpiece of Shinzo Abe's government.

Newly appointed NHK Chairman Katsuto Momii said on Jan 25 that "comfort women" — a euphemism for women forced to work in Japanese wartime military brothels — were common in countries at war at that time and that media cannot contradict the government, "cannot say left when the government says right".

The NHK leadership further fueled the situation when Naoki Hyakuta, a novelist and member of NHK's decision-making body, said earlier this month that the 1937 Nanjing Massacre never happened, adding that the United States sought to cover up its own "crimes" such as the atomic bombings of Hiroshima and Nagasaki by holding trials of Japan's wartime leaders.

On Wednesday, an editorial in the Washington Post blasted the NHK leaders' "ahistorical and offensive statements" and said Abe should condemn the dangerous rewriting of history.

"Why can't Japan's government bring itself to condemn these comments with equal clarity?" the editorial asked.

In a Feb 4 article, the Financial Times said the NHK leadership's views test the boundaries of what is considered respectable conservatism in Japan.

Agence France-Presse said on Feb 5 that Michiko Hasegawa, picked last year by Abe for NHK's management board, has praised the ritual suicide of a high-profile right-winger, saying in October, a month before her appointment, that the right-winger's self-sacrifice made Japan's emperor a living god.

"The recent controversies appear set to fuel fears among some commentators that NHK, one of the world's biggest broadcasters, is falling meekly into line with Prime Minister Abe's aggressively nationalist agenda," AFP said.

The NHK executives' views also triggered public anger in Japan.

By Monday afternoon, NHK had received 15,000 letters to the editor about Hyakuta's speech and another 2,000 for the two board members. Most of the letters criticized their statements, Asahi Shimbun said.

The Japan Congress of Journalists also made a statement on Monday, demanding Momii and Hyakuta resign from their posts.
