You can see every species found in Japanese aquariums on this site. http://web-aquarium.net/zukan/ki/index.html Unfortunately it's in Japanese so you have to blindly click around a bit The website is also slightly out of date as the last elephant seal at futami sea paradise seems to have died in 2014 at 24 years old. Regardless, Japanese aquariums have high diversity when it comes to marine mammals.
