Like with the Holocaust memorial and the Berlin Wall, these are things that have deeply affected me to see in person and comprehend what they represent, but I came away from a better person for it in the long-term—even if it broke me mentally at the time to be there and face it.
Nuclear weapons really disturb me on a whole other level I've yet to really comprehend, especially the idea that countries continue to build them. I worry about my own mental well-being with that, but feel that it's important to understand these things better and get beyond words on a printed page or digitised celluloid. Yes, these things are scary, we should be scared of them, they do scare me, just like the still-raw history of Berlin scared me. I think we run from the idea of feeling fear too often and choose to ignore it. People forget what these things do. People forget what people do to other people. We shouldn't be allowed to forget.
Before that visit I felt that I could detach myself emotionally from the reality of an event like that and make justifications for the continued existence of nuclear weapons for "bigger picture" reason. Now I find it impossible to make those kind of arguments. So I think I grew up a little that day and became more empathetic to others at an individual level.
It was honestly a bit like _being there_. Everything they have at that museum, if you have even a relatively vivid imagination, easily placed me in my mind's eye, like I was in Hiroshima for the aftermath.
Even with all this said, I'm still mostly speechless about everything I saw and read there.
I really recommend if you ever get to Japan to make some time to visit Hiroshima. Not even just for the memorial. It's actually quite a beautiful city.
(Why not? It's Japan's memorial to its war dead. All of them. Including the convicted war criminals. Visiting the shrine is seen, especially by Chinese and Koreans, as an endorsement of the war crimes. Every now and again a Japanese celebrity gets "cancelled" over this.)
It tells about the lifelong vaguely defined health impacts those exposed to the bomb had to live with, and how they tried to rebuild their lives after having truly lost everything and, for some of them, everyone.
