83% of Japanese, 66% of South Koreans say DPRK “denuclearization won’t be achieved,” Yomiuri-Hankook Ilbo poll

The Yomiuri Shimbun and the Hankook Ilbo conducted a joint public opinion poll in Japan and South Korea to probe views after the first-ever U.S.-DPRK summit held on June 12 between U.S. President Donald Trump and Workers’ Party of Korea Chairman Kim Jong Un. With the U.S.-DPRK summit and the April 27 Inter-Korea Summit, the situation on the Korean Peninsula is changing dramatically. The survey found, however, a difference in perception regarding the DPRK between the two countries. While South Koreans anticipate a thawing of tensions, Japanese are unable to rid themselves of a sense of threat from Pyongyang.


Some 59% of the Japanese and 83% of the South Korean respondents gave the U.S.-DPRK summit high marks. However, 83% of the Japanese and 66% of the South Koreans said they do not expect the complete denuclearization of the DPRK to be achieved in the near future. The majority of both Japanese and South Koreans are pessimistic about the matter although there is a difference in degree.


Regarding the relaxation of economic sanctions against the DPRK, 71% of the Japanese and 55% of the South Korean respondents said complete denuclearization must be a precondition for such a move. Some 44% of the South Korean pollees approved of relaxing sanctions in stages based on DPRK initiatives to denuclearize, exceeding the 26% of Japanese who took that same view.


When asked which countries they feel pose a military threat to their country (multiple responses permitted), 77% of the Japanese pollees cited the DPRK (88% in the previous survey conducted in 2017), while 49% of the South Korean respondents picked the DPRK (77%). The substantial decline in the South Korean figure is thought to reflect the decrease in military tensions in light of Pyongyang’s engagement in dialogue with Seoul and Washington.


Asked if “dialogue” or “pressure” should be prioritized to persuade the DPRK to abandon its nuclear and missile development programs, the percentage of pollees in both countries preferring “dialogue” increased. In Japan, pollees were evenly split, with 46% wanting “dialogue” (41%) and 46% preferring “pressure” (51%). In South Korea, pollees preferring “dialogue” outnumbered those recommending “pressure,” 60% (44%) to 20% (30%). 


The percentage of pollees who think that Japan-South Korea relations today are in a good state [including both “generally good” and “very good”] jumped by more than 10 points in each country, with 33% (20%) of Japanese and 26% (15%) of South Koreans giving that response.


The Yomiuri-Hankook Ilbo joint poll was first conducted in 1995, and the 2018 poll is the 14th in the series.
