In October 2012, I gave a lecture titled "Post 3/11" at a university in Busan, South Korea. In the speech, I spoke of Germany's clear policy shift away from nuclear power.
After the lecture, a student asked, "I wonder if the reason that Japan cannot abandon nuclear power even though Germany has decided to do so is because, compared with Germany, Japan has not reflected deeply enough on its wartime behavior."
I gave an ambiguous response: The issue of dealing with nuclear power and reflecting on the war are two totally different matters and, moreover, Japan's regret regarding its war is clearly apparent if you look at Japan's postwar path as a peaceful nation. But I began to think that perhaps there are people who do not reflect at all on the war Japan waged.
