OSAKA – Calls in the Diet for legislation to curb hate speech targeting foreign residents of Japan are being made even as the issue barely registers on the campaign trail for the July 21 Upper House poll.

Over the past six months, demonstrations and parades against foreign residents, especially Koreans, have grown in intensity. In Osaka’s Tsuruhashi district, home to large numbers of “zainichi” resident Koreans, a 14-year-old girl in February using a microphone loudly maligned Korean residents, saying she despised them and warned them to relocate to the Korean Peninsula or be massacred.

Her comments were reported worldwide and were followed in the months afterward by anti-Korean demonstrations in Tokyo and Osaka that grew, with protestors holding signs saying “Good or Bad Koreans: Kill them All.”

Yoshifu Arita, an Upper House member of the Democratic Party of Japan who is leading a Diet effort to enact legal measures curbing such speech, says things have calmed down only recently after politicians began speaking out.

“On May 7 in the Upper House, (Prime Minister Shinzo) Abe said these demonstrations were ‘regrettable.’ Justice Minister Taniguchi used the same word. Chief Cabinet Secretary (Yoshihide) Suga also said these were ‘not good things,’ ” Arita told the Foreign Correspondents’ Club of Japan on Tuesday in Tokyo, referring to terms habitually trotted out by politicians in lieu of serious condemnation.

Over the past six months or so, it has been the rightist group Zaitokukai that has been responsible for much of the hate speech. Arita said this was not a coincidence. “Zaitokukai was established during the “right-leaning” Abe’s first administration in 2006 and 2007, and started escalating their aggression after the resurgence of (Abe’s) Liberal Democratic Party and the advent of his second administration last year,” Arita said.

Judging from Abe’s rhetoric in May, Arita doubts the prime minister in particular would be seriously inclined to sign on to any sincere legislative effort to ban such virulent talk.

“In the most recent edition of the monthly magazine Bungei Shunju, Abe was asked about hate speech. His response was ‘I leave this matter to the good conscience of the average Japanese,’ ” Arita said. “But politicians must take responsibility for trying to resolve this issue. The fact that Abe can make such a comment fills me with doubt about how seriously he’s taking it.”

Nor do most Diet members seem to want to mull legal bans.

In late May, a network of 84 human rights nongovernmental organizations conducted a poll of all 717 Diet lawmakers on how they felt about hate speech, getting replies from only 46, although they represented all major parties except the Japanese Communist Party and Nippon Ishin no Kai (Japan Restoration Party), whose co-leader, Osaka Mayor Toru Hashimoto, drew international scorn over his attempt to justify wartime Japan’s use of sex slaves, in large part Korean, for the military.

Forty-three of the 46 said they thought a national response to the rise in hate speech was necessary, while 41 said they supported the idea of the Diet investigating hate speech incidents. All 46 indicated the Diet should consider an antidiscrimination law that bans certain kinds of hate speech.

Arita said hate speech not only targets foreign residents and also has the potential to escalate.

He noted incidents in which politicians, during speeches that may touch on topics certain members of the audience may disagree with, find hecklers calling them “traitors” or “people selling out our country.”

“These are words you see not only on the Internet but actually thrown in politicians’ faces when they’re giving their speeches. We’ve not really seen this kind of situation in Japan in the postwar era.”
