Please come and visit here sometime, if you could. It's a nice place to visit these days. (You should say something positive about Hiroshima if you hope to welcome or introduce people to visit there. It would not be appropriate to suggest visiting after mentioning something perceived as being a negative attribute to the location).

Bye Bye!
