Visitors to the aquarium are immediately drawn into the experience by stepping in front of the massive floor to ceiling Kuroshio Great Water Tank right after they enter. This approximately 1,360,000 liter tank focuses on the Kuroshio current; the current that runs off of Japan's eastern coast and is essential for supporting a wide variety of marine life. A large whale shark, graceful manta rays, and shiny tuna all glide right in front of your face. As you exit the large tank room, you walk right under these magnificent creatures, as the tank curves over your head.
Kagoshima City takes particular pride in its marine life and the aquarium features many species that are indigenous to the local area. Those familiar with the southern port towns such as Makurazaki will recognize the shiny tuna (katsuo) in the huge 1st-floor tank, for example. Perhaps the most intriguing residents are the taka-ashi (lit. tall leg) crabs, whose leg spans can reach nearly 4 meters! These somewhat fierce-looking, yet serene animals are prevalent in the warmer waters between Kagoshima Bay and Tokyo Bay. Jellyfish, eel and squid are other creatures you can learn about through exhibits that are translated into English.
