2. Key Features of Osaka Aquarium Kaiyukan

a. Innovative Design and Layout

The aquarium is designed in a unique manner: rather than having separate tanks for each species, the aquarium follows a circular design where visitors travel through different exhibits on a ramp that spirals downward. This allows them to experience the aquatic life in a more immersive way. The central exhibit features a large tank that serves as the focal point of the entire aquarium.

• The Central Tank: The centerpiece of the aquarium is a massive tank called the Pacific Ocean Tank, which holds 5,400 tons of water and is home to various species, including the whale shark and giant rays. The tank is so large that it’s visible from many of the other exhibits, giving visitors the sense that they are surrounded by the ocean.

b. Thematic Exhibits

The aquarium features 15 main exhibits, each showcasing a different environment or ecosystem of the Pacific Ocean. Some of the key areas include:

The Pacific Ocean Tank: This is the largest exhibit in the aquarium and holds an array of marine species, including the impressive whale shark (the world’s largest fish), giant manta rays, sunfish, and many types of tropical fish. The tank is designed to replicate the open ocean environment.

Antarctica: This exhibit mimics the cold waters of the Antarctic region and is home to Adélie penguins and King penguins, among other cold-water species. The penguins are often a favorite attraction for visitors, as they are very active and playful.

Great Barrier Reef: This exhibit replicates the vibrant and colorful coral reefs found in Australia’s Great Barrier Reef. It’s home to a wide variety of tropical fish, including clownfish, anemones, and sea turtles.

Jellyfish: One of the most mesmerizing exhibits, this section is dedicated to jellyfish, where different species float gently in illuminated tanks. The graceful movement of the jellyfish makes it a calming and beautiful experience for visitors.

Japanese Forest: In this exhibit, the aquarium showcases the rivers and forests of Japan. It features creatures such as Japanese giant salamanders, koi, and various species of freshwater fish.

Bay of Panama: This exhibit replicates the warm waters of the Pacific Ocean and showcases species such as sea otters, Pacific Ocean stingrays, and other marine animals from the area around Panama.

d. Night Aquarium
