In Hiroshima City, two scenic spots can be visited at the same time. The shrine is quiet and serious. There is a place for people to wash their hands at the entrance. Maybe it is a ritual in the preface. Then they go in and visit. They also have diagrams to teach tourists the whole procedure.
All the worshippers here are those who have contributed to the establishment of Japan.
You can drop in on Hiroshima City. It's next to the Atomic Bomb Explosion Memorial. The newer buildings are empty. Build in an open square. There are not many visitors. It's a bit bleak.
If you have to say the difference, it is more open.
