About Osaka Aquarium Kaiyukan
Osaka Aquarium Kaiyukan is widely considered one of the largest and most spectacular public aquariums in the world. It is renowned for its innovative spiral layout that takes visitors on a journey through the aquatic habitats of the Pacific Rim. Its crowning jewel is a massive nine-meter-deep central tank that houses majestic whale sharks and manta rays.

Plan your visit
Visit on a weekday morning right around opening or after 5:00 PM to experience the tranquil evening ambient lighting. Avoiding weekend afternoons will help you steer clear of the heaviest crowds and tour groups.
Admission requires a paid ticket. It is strongly advised to book timed-entry tickets online in advance to avoid long ticket counter queues, especially on weekends and national holidays.

- Wear comfortable walking shoes, as the continuous downward spiral ramp spans multiple levels.
- Download the official audio guide or visitor app on your smartphone for detailed species information in English.
