Osaka Aquarium Kaiyukan

4.4 (200)AquariumTourist AttractionPoint Of InterestEstablishment

Osaka Aquarium Kaiyukan, situated in the Minato ward of Osaka, stands out as one of the world's most expansive and innovative public aquariums. This facility takes visitors on an aquatic journey through various regions of the Pacific Rim, each tank representing a specific area of the Pacific Ocean.

The aquarium's layout is designed to take visitors on a descending spiral path, allowing them to view marine life from different depths and perspectives. One of the main highlights is the massive central tank, which simulates the Pacific Ocean environment and houses awe-inspiring whale sharks alongside a diverse array of other marine species.

Osaka Aquarium Kaiyukan is home to around 30,000 creatures encompassing 620 species, including otters, dolphins, penguins, jellyfish, and rays, presented in 15 tanks, each focusing on a specific region of the Pacific Rim. The "Japan Forest" tank, designed to resemble the Japanese woodland, and the "Antarctic" tank, home to playful penguins, are among the visitor favorites.

The aquarium is not just about observation; it's an educational experience, offering insights into marine ecosystems and the importance of conservation. For a more interactive experience, visitors can opt for the Kaiyukan's touch pool or take a behind-the-scenes tour to learn more about marine life and the workings of an aquarium.

What other travelers are saying about Osaka Aquarium Kaiyukan

I absolutely loved the aquarium! It was so amazing and the whale sharks and other animals were so amazing to see. They obviously take very good care of all of them and we even got to see the workers feed them! Super awesome experience and I would absolutely go again ❤️ But make sure to reserve tickets!! We did and skipping that super long line was worth it

This is definitely one of the better aquariums I’ve been to in a while. Clean, well-marked and 5 stories high of sea animals seen through thick glass of clear and bluey waters. The main highlight of the aquarium is definitely the penguins and sharks which can get crowded at certain points as tourists and others try to get up close as they can for perfect shots. For ¥1800, I can say that it’s a great experience for everyone and for your kids if ya wanna take em on a great day.

We had an amazing experience at the Kaiyukan Aquarium! The highlight of the visit was definitely the numerous whale sharks – it was absolutely fascinating to see so many of these majestic creatures up close. The main tank, with its incredible size and variety of marine life, was mesmerizing. You could watch the whale sharks swimming gracefully alongside other stunning sea creatures.

An impressive aquarium. Most tanks had plenty of space, but some exhibits could do with being bigger. A vast range of amazing species on show here, and the whale sharks were stunning. It takes about an hour or so to complete, but take time to stop and look at the amazing marine animals here.

We love this aquarium, so much to see and experience. Suggest to buy tickets in advance if you’re traveling in big groups during the peak season. Entrance entering is fast but the ticketing line can be long awaiting on peak period. The aquarium is organized based on the creatures region and its continents. The deep sea creatures is well viewed in its aquarium and they are active. The birds and mammals are healthy and adorable. Worth a visit to experience them.
