Since other reviewers have so wonderfully summarized the excellence of the film, I will try to review it from a different perspective.
As a Japanese citizen living in Japan, and as a citizen of the only country in the world to have experienced atomic bombings, I believe this movie is a must-watch for all Japanese people.
Certainly, some Japanese may feel uncomfortable watching this movie, but I believe we should set aside such emotions and view it objectively. We should ponder why the atomic bomb was created, what its purpose was, and the historical consequences of its development.
Indeed, after the atomic bomb was developed, major wars among advanced nations (especially nuclear-armed countries) ceased. It is a fact that the atomic bomb served as a deterrent. Perhaps the world needed an opportunity to truly understand the horror of atomic bombs at that time.
I do not intend to blame those who developed or dropped the bomb. History cannot be changed. However, we must learn from it and focus on how to move forward.
While the atomic bomb served as a deterrent, wars still persist today. There are casualties on both sides of war. If we were to visit countries without war, people from warring nations could become friends.
This movie made me reconsider the purpose of the atomic bomb. I believe we should strive to utilize our brilliant minds and technology to create a better future. There were legitimate reasons from different perspectives for dropping the bomb, even for Japan. It's necessary to forgive, reform, and work towards a better future.
With the internet, people around the world can share information. I believe everyone can become friends and love each other. The ugly act of war should disappear from the world.
This movie deeply encourages us to contemplate such matters. As a citizen of the only country to experience atomic bombings, I firmly advocate for peace and oppose war.
