If you go to the Japanese version of Asahi and Nikkei (and other major Japanese newspapers), you can find quite a few articles on this issue. I have already read close to ten articles on the issue in both Asahi and Nikkei (including shasetsu). Abe justified his poorly-thought right-wing opinion but this further hardened China's and South Korea's stance against Japan. These countries also agreed to set up a hotline on the North Korean issue by ignoring Japan.
