Home to around 120 aquariums ranging in size from large to small, Japan is known for being an "aquarium kingdom." However, after observing both aquarium staff and the visitors that come to the aquarium for fun, it seems there is a gap in the thoughts and expectations between the two sides. For aquariums in future, it will be important to not only fulfill the objectives and roles that are demanded of them, but also make efforts to become facilities that are enjoyable and of importance to the visitors.
