Your day begins with entry into the main attraction, the Pacific Ocean zone, home to the famous whale shark. This massive creature, the largest fish in the world, is the highlight for many visitors. Seeing it glide gracefully in a large tank is a memory that tends to stay with travelers long after their visit.

Next, you’ll explore the Japanese Forest, a tranquil exhibit that showcases local marine ecosystems. This zone gives a sense of calm and intimacy, with displays of native seaweed, fish, and other marine flora. It’s an ideal spot to appreciate Japan’s own aquatic environment in a peaceful setting.

Moving on, the Antarctic Circle exhibit hosts adorable penguins, which often delight children and adults alike. The penguins are lively and seem curious about visitors, offering fun photo opportunities.

The Great Barrier Reef display is vibrant, featuring over 5,000 coral formations and colorful fishes. This part of the aquarium provides a sensory feast with bright corals and darting schools of fish, making it one of the most visually striking exhibits.

Finally, the Deep Sea off Japan transports visitors hundreds of meters below the surface to see Japanese spider crabs and other elusive, deep-sea creatures. The dark, mysterious atmosphere of this zone gives a real sense of the ocean’s unexplored depths.

The Value of Guided and Informed Displays

Many reviews highlight the importance of knowledgeable guides who help explain the exhibits. They provide context that enhances understanding, from the biology of the animals to conservation efforts.
