Last week when we went to Aquas we didn't actually go into the aquarium, but explored behind it (there is no entrance fee to the park :))
I was very pleasantly surprised, it is a nicely landscaped garden with artificial stream and pond.
There is a solar-heated atrium, and from inside it one can descend and come out
...behind an artificial waterfall.
There is a big playground for the kids ( and adults who can appreciate it :)
The bright, sculptural play area was designed by painter Kei Amatsu who lives in Tsuwano and who has executed a lot of public art in Shimane and across Japan.
And of course, across the bridge in front of the aquarium is 5 kilometres of fine sandy beach.
All in all, you can spend a pleasant few hours at Aquas without spending any money
