Weeks after a U.N. special rapporteur released a surprise open letter slamming a state-backed conspiracy bill that critics warn could erode privacy and free speech rights, the Cabinet of Prime Minister Shinzo Abe has shown no sign of letting up on its targeting of the statement.

If anything, it has been hellbent on discrediting what it claims was an “inappropriate” rebuke by the United Nations expert.

Tokyo’s ongoing clash with Joseph Cannataci, a U.N.-commissioned expert on the right to privacy, is reminiscent of a similar war of words it has fought with U.N. special rapporteurs in recent years. Many of the probes by those officials into the human rights situation in Japan have led to conclusions often at odds with the government line.

Experts are split on how seriously their words should be taken, with some questioning their objectivity and the validity of their methodology while others argue that Japan, as a progressive democracy, should demonstrate a more humble approach to criticism.

As he spoke to the Upper House plenary session on Monday, Abe openly blasted Cannataci’s assessment as “extremely unbalanced” and said his behavior was “hardly that of an objective expert.”

On Tuesday, his Cabinet approved three official statements condemning the official’s letter, which it claimed was drawn up “based on misunderstanding” and without the government ever being afforded an opportunity to thoroughly explain to him about the proposed legal revision.

In these statements, the Cabinet reiterated the government position that Cannataci’s critique did not reflect U.N. views. Prior to these statements, Tokyo had swiftly lodged a direct protest over the issue with the office of the High Commissioner for Human Rights (OHCHR) in Geneva.

“When there is a misunderstanding of facts, it is of course our position that we get our message across,” said a senior Foreign Ministry official, who spoke on condition of anonymity.

On Wednesday, the government’s position was on full display when Deputy Chief Cabinet Secretary Koichi Hagiuda launched into a separate attack against another U.N. special rapporteur’s criticism of the government.

Hagiuda said it was “extremely regrettable that the government position was not fully reflected” in a report issued Tuesday by David Kaye, U.N. special rapporteur on the right to freedom of opinion and expression. In his report, Kaye had pointed out “significant worrying signals” for Japan’s freedom of expression.

In yet another incident, the Foreign Ministry lodged a strident protest with special rapporteur Maud de Boer-Buquicchio in 2015 over what it labeled a factually dubious claim that “13 percent of Japan’s schoolgirls have engaged in compensated dating (enjo kosai).”

According to the OHCHR website, special rapporteurs are independent human rights experts who “are appointed by the Human Rights Council and serve in their personal capacities,” with mandates to report and advise on human rights. They are not U.N. staff members and receive no financial remuneration, it says.

In this regard, the government assertion that Cannataci’s letter does not represent the U.N. stance is “valid,” said Ichiro Kawabe, a professor of U.N. studies at Aichi University. But at the same time, he said, these experts’ commentaries are not hostile in nature and are designed to foster constructive discussions on human rights issues.

“Being a developed country, Japan is in a position to improve the global standards of human rights. So what it should be doing is not to overreact to what it considers to be a factual error every chance it gets, but listen humbly to what the experts have to say,” Kawabe said, adding that he was not aware of any other developed nation that had protested against special rapporteurs so vociferously and consistently as Japan.

At the same time, however, some take a dim view of approaches taken by special rapporteurs, who they say tend to base their reports on interviews they had with those concerned, but fail to independently fact-check what they have learned afterward.

In slamming Kaye’s preliminary report on freedom of expression, a circle of conservative scholars in Japan last month released an open letter questioning his methods. In it, the group alleged his report was “based on interviews with a limited number of journalists when he visited Japan for just one week” and that “the academic analysis is sorely lacking.”

This claim, however, failed to note that Kaye did meet government representatives to hear their side of the issue, as well.
