The aquarium is located at an elevation of approximately 300 meters above sea level on a historical lava plateau.
It is one of the few facilities in Japan that exhibits West Indian manatees.
The venue offers an unobstructed view of the Takamatsu cityscape and the surrounding islands of the Seto Inland Sea.
The site was formerly known as Yashima Aquarium before undergoing a transition and rebranding as New Yashima Aquarium.

New Yashima Aquarium is situated atop the Yashima plateau, providing panoramic views overlooking the Seto Inland Sea. The facility specializes in marine life exhibits featuring manatees, dolphins, and seals. Visitors can view various species within a compact footprint designed for observation. Regular live demonstrations featuring trained marine mammals are held throughout the day. It functions as a regional attraction highlighting aquatic biodiversity in Kagawa Prefecture.

Check the daily schedule upon arrival to coordinate your visit with the dolphin and seal performance times.
Wear comfortable walking shoes as the area surrounding the aquarium involves navigating the sloped terrain of the Yashima plateau.
Bring a camera with a wide-angle lens to capture the unique contrast between the aquarium pools and the expansive sea views.
Assuming the aquarium is located at sea level; it is atop a high plateau and requires transit to reach the summit.
Generally open daily, but may close occasionally for facility maintenance or during extreme weather conditions impacting the plateau access.
