The Osaka aquarium is basically a functional concrete structure build around a pool big enough to hold two whale sharks.
There are smaller ones too.
And …
I get an idea what might have inspired japanese mythology to produce such an abundance of demons and monsters. Maybe to explain the real threats: earthquakes, tsunamis, typhoons and landslides.
I observe a strict safety first mentality.
I see it in the layout of things …
… and in the way things are done.
Well, … on the other hand people choose to live right next to an active volcano.
I guess the robots will save the day.
Good Luck.
