The KAIYUKAN is an aquarium that faithfully recreates the natural environment of the world’s largest ocean, the Pacific Ocean, and its surrounding waters.

Each region of the Pacific Rim that surrounds the Pacific Ocean is recreated in a large water tank.
Each tank in the aquarium is arranged in a way that is similar to how they are actually located geologically in the Pacific Ocean. Starting with the “Pacific Ocean” tank that is home to the majestic whale shark, or the “Forest of Japan” tank that is lush in vegetation and flowing waterfalls, to the “Tasman Sea” tank that houses the Pacific white-sided dolphin, each of the tanks in total houses and displays approximately 30,000 creatures with 620 types of species.

Other popular tanks include the “Jellyfish Galaxy” that are all about the jellyfishes, or the “North Pole” tank that houses the Ringed seals.
