Japanese Sangiinn (upper house) passed a contentious legislation to allow Japan to play a larger military role in world conflicts, even though 42 % of Japanese are still against such legislations. True, 70 years have already passed since the end of that disastrous war in 1945, but many Japanese still remain traumatized by the experience that almost obliterated their nation. As Masuji Ibuse expressed in his novel Black Rain, many Japanese still feel: “I hate war. It doesn’t matter if we win or lose as long as it ends quickly. I prefer unjust peace to the so-called just war.” I sympathize with and understand such a sentiment because it shows a profound level of trauma the victims of atomic bomb blasts underwent. On the one hand, I feel Japan should stay as it has been for the last 70 years as a unique nation that disavowed the right to get involved in armed conflicts. Japan has been a lovable and idyllic nation regardless of frequent natural disasters, petty crimes and political and business corruptions. Japanese people, generally speaking, have been peaceful and upright albeit a little naive. What’s wrong with Japan’s Defense army playing the role in Japan and the world that is comparable to the firefighters’ role in societies? However, I also believe that Japan should become a more “mature” nation that can make sound and responsible moral judgements to what’s happening in the world. I do not believe unjust peace is better than just war, though war should be avoided by all means possible.
