I was reminded once again of the importance of peace. It was much less crowded and more comfortable than Hiroshima, and I was able to look around at my own pace. The year was written on the ramp at the entrance, which made me realize that war isn't such a thing that happened so long ago. I bought my ticket in advance, and entry was smooth.
The tickets are simple and convenient to use. Yes, the internal maintenance in August was quite good. Although it is built on a hillside, the accessibility facilities are very well done.
