Such a cool aquarium! It may seem like a strange place to visit as a tourist, but if you're a fan of marine life, I highly recommend it! The main tank at the center of the aquarium was truly spectacular. It was my first time seeing a whale shark, which was really awe-inspiring. Their exhibits were very nicely displayed, and most had English translations. They also have these cute stamps in each exhibit room that you can collect in a booklet, and it's a fun way to keep kids (or silly adults) engaged and exploring.

The aquarium was a standard recommended tourist destination at Osaka, so we decided to give it a go. It is one of the biggest aquariums in the world. While the displays we're good, the place was fairly crowded and at certain spots, it felt more like a crowded market Street compared to a beautiful aquarium where one goes to enjoy serenity of nature. Alas, once you get over the crowds, there certainly are some amazing exhibits. For the big tank, I would recommend continuing your walk down the spiral walkway to reach mid level, where there often is less crowds and there are seats which you can sit and enjoy the fish swim. Towards the end there is a tank of stingray which children can touch. My son enjoyed the experience, but I was not game enough to do it. Overall it's another tourist attraction worthwhile a visit to say you have done it but definitely worthwhile for families with younger children.

A good place to visit and gain knowledge. Highly recommended to go with kids. You can buy a passport and collect stamps through your underwater journey! Or create your own to your kids and collect the stamps all the way! They're also disabled friendly buildings. You can starts taking pictures from outside because there are lots of lighting (if you come at night).

This is a great aquarium, a place with so much to see even for regular aquarium fans like me. The sheer size and the variety of fish should be enough to persuade any visitor of Osaka to come to this attraction at least once. The downside of the place, though, is that there are simply too many people at any given time. I have never been here in the evening, but during the mornings and the day, it is very hard to enjoy any single tank because of the various people taking pictures, recording a video or having a simple chat with his/her company. You can't blame them though, there are no rules against enjoying a tank for yourself 😝 The other thing I found missing here was that being such a gigantic aquarium, this is more like a 'bazaar' should I say... of fish, rather than a coherent story. This shouldn't be a matter for people who just enjoy seeing a good variety of fish, though.

Sorry to say, I was quite disappointed by this "attraction". Maybe I am spoiled or expecting too much since it is supposed to be the "largest aquarium in the world". I seriously doubt that. It may also be my own fault for going on a weekend, but here goes. For the first 20-30 minutes, all I could see was 6 rows of the backs of people's heads. I'm 6' tall, so I should have been able to see something. That didn't matter too much since except for the tunnel, the first few exhibits were lacking. Once we got through the crowded beginning, the displays opened up enough to see more. I did like the big tank with the whale shark. I do think there were too many fish for the volume. Some of the fish didn't look very healthy, and I was surprised by how murky the water is in all of the tanks. Overall, I expected bigger and more. I've been to several aquariums in the US, and they all seemed nicer than this one. I guess that about sums it up. I can't tell you to go or not to go, but at least now I hope you are more prepared than I was.

An awesome place to go. Highly recommended. This is by far the best aquarium I have been in. It has a lot of sharks variants, and even allowed you to touch the sharks (in a safe zone area). Penguins, turtles, sting rays, mantas, whale shark, and many more sea creatures are there for you to sight see. Jelly fish arena was amazing. Kaiyukan did such a great job maintaining the fishes in an environment that is kept in high quality. Excellent job!

Visited Kaiyukan on November 2017, reached that place at almost 4 pm.. really an awesome aquarium. So many various of aquatic animals can be found there. Not just the giant fish species but also met ‘Nemo and Dory’.. little fish with beautiful color; spider crabs which never seen before; the ugly face fish but cute one.. and many many others.. Four hours ran so fast and at 8 pm the aquarium was closed. Overall visited was very satisfied with little hope..visit this place again some day with more family members and friends.

If you've ever wanted to witness osne of the most comprehensive and extensive aquariums in the world, be sure to visit the Osaka aquarium! With it's headline exhibit being a pair of beautiful whale sharks, this place is sure to impress. With displays from all around the globe, there are truly some extraordinary sights. There are dolphins, turtles, star fish, and more. There's even an exhibit on the cook straight, which is right next to home, how beautiful. If you manage to get there around sunset, you'll also get some gorgeous views of the Osaka harbour with a setting sun lighting the view. It's truly a gorgeous sight.

Hands down the best aquarium I've ever visited. It's organized in such a way as to make the visit simple, informative and fun. The escalator at the entrance will bring you to the top, from which a path circles back to the bottom, revealing the main tank in the centre after only a few turns. That tank is the highlight of the exhibit, not only because of the two whale sharks that majestically grace its water, but also for the appeal of the many other species of fish, rays and smaller sharks. The end brings you to a separate area where you can touch some sharks and rays back's, gently... and the requisite souvenir shop. All in all, fun for kids and adults as well. One last thing, visiting on a Friday evening, we found the place relatively quiet. A bonus in a populated city like Osaka, even if it was a rainy evening conducive to indoor activities!

We've been to several aquariums and our family love this. It's not too big and overwhelming but still exciting. There are a lot of interesting collections such as whale shark, smiley face seal, penguins and giant crabs. My toddler loves it very much. I'm really impressed with the jellyfish collection because it was WONDERFUL, mysterious and beautiful at the same time. I've never seen such collection before. Surely it's kids friendly, baby stroller friendly and the ambiance is calming inside. Children will surely love the souvenir shop! Recommended for family!

VERY busy today, but a STUNNING aquarium. Even though it's busy, you hardly get pushed around. And a little patience does wonders, because you'll be able to observe everything if you wait a little. A tip for 1st time visitors, don't take all your pictures the first time you see the main basin. It'll be much quieter further down into the aquarium and you'll be able to get amazing pictures there!

This aquarium had great exhibition. The central giant tank with whale sharks was mostly impressive. Nice floor plan and route design to flow the traffic. The only minor issue was that some exhibition was on one side of the hallway where virtually all visitors were leaning toward. This place was very popular and easily crowded, which might call for additional attention to kids.
Stephany Cuellar | May 29, 2018
This aquarium is one of the best I've ever been to. This can easily take a whole day of relaxing and enjoying all the animals. There is so much to see as far as the animals go there are otters, capyberas, the whale sharks, sunfish, spider crabs and so many random animals! There were lots of animals I had never even seen before. This is not to be missed! The restaurant itself has great views of the bay. Great place to take kids and take pictures! Good time if you have an extra day before or after universal japan

Amazing aquarium! It is definitely a must see in Osaka. The aquarium is several level and you start I the top. This is a fantastic Aquarium if you are looking to see a lot of what Japan as to offer in its water. They have a huge tank in the middle of the aquarium with a whale shark that is swimming with other sharks and big and small fish. This a fantastic experience and recommend it over Tokyo's Aquarium. The price is better and the layout of the aquarium is much better.

If you have 2-3 hours to spare, this is a great stop in Osaka! Great selection of aquatic friends! Feeding schedules posted at the entrance so be sure to make a note of which ones you can attend. 7? Floors of fun in store for you! I liked the famine flavored ice cream at the cafe in the middle of our walk through.
Stephanie Morse | Jul 14, 2018
This is a terrific aquarium. We visited on a rainy day. It's really kid-friendly and they did an excellent job designing the space so that you can get many different views of the tanks. I loved that they had a stamp rally for the young ones and the touch tank. My reason for a 4 star is that some of the tanks seemed really small for the animals living there. But if you're traveling to Osaka and need something to do on a rainy day, this is a great choice.

Love this aquarium so much! It got a range of lovely sea creatures with lots of big glasses so that we can see them more closely. It got many interactive games as well! I particularly love the lovely seals who followed the movement of a kid on the other side of the glass! It’s so funny! We had a great time in the aquarium!
Guy Monticello | Jul 20, 2018
This is the best aquarium I have ever been to! I love the layout of this aquarium! The animals here are amazing and there are so many different ones to see..... Also, the aquarium itself is huge! There are so many things to see and do here which makes it great for kids and adults alike! Make sure to plan accordingly if you want to see the entire aquarium as it is really big! So make sure to go with enough time so you can enjoy everything and not be rushing. Again, this is by far the best aquarium I have ever been to and I definitely do recommend it to anyone in the area! This aquarium is a must see!

This place is incredible. The variety of animals, but also the loads of educational content makes this place a must visit while in Osaka. The whole place is accessible. Quick tip; it gets crazy packed in the day time. Go later in the day or closer to close time (8 PM) to experience the aquarium with more ease.
Ricky Lee | Aug 16, 2018
Came to this aquarium over 20 years ago... This time brought my children and it did not disappoint! I love aquariums... This is probably my favorite in the world! I could spend the whole day looking at the main tank... Some new additions we're really nice too. Will be back again someday.

No shows or particularly interesting exhibits, but you can explore floors 7 - 3 which has different tanks. Some of the bigger tanks take up 2-3+ floors and it's cool to see the animals both on land and under water. Some animals are more illusive, so try to go during feeding time to catch their attention. Would avoid mornings and early afternoons as they're filled with tours and school children.
