Introduction
Welcome to Osaka Aquarium Kaiyukan, one of Japan’s largest and most spectacular aquariums! Located in the Tempozan Harbor Village, this immersive experience takes you on a journey through the Pacific Rim’s diverse ecosystems. With its iconic whale sharks and innovative vertical design, Kaiyukan isn’t just an aquarium—it’s a mesmerizing voyage into the ocean’s depths.
Getting There
- By Train: Take the Osaka Metro Chuo Line to Osakako Station (Exit 1). A 5-minute walk brings you to the entrance.
- By Ferry: From Universal Studios Japan (USJ), hop on the Captain Line water bus (15-minute ride).
- Pro Tip: Combine your visit with the Tempozan Ferris Wheel next door for stunning harbor views!
The Layout: A Spiral Journey
Kaiyukan’s genius lies in its vertical spiral design. You start on the 8th floor and descend via ramps encircling the Central Tank—a 9-meter-deep marvel housing whale sharks. Each floor represents a Pacific region:
- Japanese Forest (Floor 8): Otters and salamanders in a misty woodland.
- Aleutian Islands (Floor 7): Playful seals and sea lions.
- Panama Rainforest (Floor 6): Piranhas and electric eels in a humid jungle setting.
- The Great Barrier Reef (Floor 5): Tropical fish and coral tunnels.
- The Pacific Ocean (Floors 4–1): The showstopper central tank with whale sharks, manta rays, and schools of tuna.
Unmissable Highlights
- Whale Sharks: The world’s largest fish glides gracefully in the Central Tank—capture them during feeding time (2:30 PM daily).
- Interactive Zones: Touch sharks and stingrays at the “Touch Pool” (Floor 4).
- Jellyfish Gallery: Hypnotic displays in a dark, dreamlike room (Floor 2).
- Antarctica Exhibit: Adorable penguins waddling on ice (Floor 3).

Why Kaiyukan Stands Out
Unlike traditional aquariums, Kaiyukan replicates natural habitats with meticulous detail. The slow descent through dimly lit tunnels makes you feel like a deep-sea explorer. Watching sunlight filter through the Central Tank as a whale shark drifts overhead is pure magic.
Final Thoughts
Osaka Aquarium Kaiyukan is a must-visit for nature lovers and families. Allow 3–4 hours to fully soak in its wonders. Pair it with a sunset Ferris wheel ride for the perfect Osaka day!
