Where was Asano Park in Hiroshima?

I've recently read John Hersey's Hiroshima and was looking at a map of Hiroshima trying to put into context where the main characters were and where they headed to. However, I can't find Asano Park anywhere. I've tried googling it, and still can't find any information on whereabout it is/was apart from it was on a river bank. Can anyone tell me if it's changed its name since then? If it still exists and whereabouts it was? Thanks in advance.

It seems to be Shukkeien According to this.

Thank you Haro. That's brilliant. :)

I'm Japanese, living in Hiroshima. Asano park exists. But we never call it Asano park. We call it shukkeien.

It's a beautiful garden park, including three miraculous
trees survived atomic bomb. It's worth viewing.
In western world, some people call this park "Asano park", because long time ago Christian missioner called so. (Long time ago the park belonged a feudal lord named Asano.)

I'm told Shukkiken (Lord Asano's old estate) is not to be missed. Wish I had known this was the park where the people Hersey wrote about, acquaintances of Father Kleinsorge, fled to escape the advancing fires. Next trip, for certain. I have narrowed down the other locations prominent in Hersey's book; it isn't easy as he is using pre-War names and names with Christian connotations but the City of Hiroshima website is a goldmine of info; you can locate the REdcross Hospital, the likely location of Dr. Fujii's clinic, the no-longer in existence East parade Grounds, and the suburb of Koi and Ujima. Cant yet nail down the East Asia Tin Works; I think it is across the river running to the west of the Peace memorial Park. Very glad to see interest in Hiroshima and the details of the atrocity. Standing on sites where notable events in the conflagration occurred helps to bring the horror to life as having happened to a city and not in a lovely Memorial.
