  • This is a great aquarium, a place with very 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. 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. 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.
  • Best aquarium experience ever. All the marine lives here are very active and playful. You could easily spend hours here. The whale sharks are just amazing.
  • Very big aquarium. It has a big tank in the middle and basically you are walking around it from top to bottom floor. You can really get very close to all the marine life there. Climax are at the bottom where you see the entire center tank. It's a great experience. But be prepare as it's very crowded with visitor.
  • I didn't like that for most of the aquarium, you're herded through a viewing route, which created congestion and chaos. It was difficult to enjoy the beginning of the route because there were so many people. I loved the giant whale shark tank with many levels of viewing areas. It was fascinating to watch during feeding time. We were able to catch several feedings because of the helpful signs posted by the various exhibits which state the times. Also very enjoyable was the hands-on exhibit with sharks and rays. Tips: Dress in layers in - it was hot and uncomfortable at the beginning (we visited in summer), but got really cold toward the end Arrive early to avoid the masses, or visit during off season (if there is one) Don't get hung up in one spot for the main tank - lots of places to view from! However, the upper levels are the best for viewing the whale sharks
  • The aquarium is huge, a full 8 floors with turtles, sharks, fish, etc etc, and a whole jellyfish area. I love the full glass displays that really let you see the whole length of the tank. My favorite part was the petting area where you got to pet stingrays and sand sharks. It was a fun experience where every section had something new to look at. Good place for kids too. Would definitely recommend taking note of the feeding times for the different animals, especially the dolphins. You pretty much get a show when the staff feed them. Feedings happen 3x/day. I wouldn't go back a second time, but it's a really great experience.
