Yes, there are. I have a book on WW2 that shows the city after the bomb and there isn't much standing. I suggest you go to the library or look on a site about ww2 or the atomic bomb.
Plants do grow where Hiroshima was bombed. In fact they began rebuilding the city in 1946. It is a very beautiful city. There are beautiful pictures on the web of the city.
Japan didn't surrender in a city, but on the US Naval ship the Missouri. She is in dry dock(I think) and is a historical site today. You can visit her.
