Good for kids and adult! Feb 26, 2012
Not to be missed if you love aqua life. I don't know why but these fish and mammal are so cute in Japan! The unique part of this aquarium is - you can touch them! for free! Don't leave when you finish your walk, there is a area for you to touch them in the shallow aquarium. You can touch a baby shark or baby Aetobatus! To me it's wonderful experience to feel this beautiful creatures and it's so enjoyable to see the cute kids to touch the fish and feel scared but they enjoy it so much!

Osaka Aquarium (Kaiyukan) is located in Tempozan Harbor Village in the Osaka Bay area, right next to the Suntory Museum. Kaiyukan literally means "playing in the Sea Pavilion". It is only a five minutes walk from Osakako Station on the Chūō subway line. When exiting from the subway station look for the enormous ferries wheel. There are no signs pointing you to the aquarium.

Osaka Aquarium consists of 15 water tanks spiraling around a huge tank holding 11.000 tons of water (5.400 cubic meters). The 15 tanks represent a specific region of the Pacific Rim. The central tank, representing the Pacific Ocean, is nine meters deep and the home of two whale sharks.

After you have entered the aquarium you start your visit through a tunnel-shaped tank with sharks, rays etc, before you ascend the escalator to the 8th floor. Then you slowly spiral down floor by floor around the main tank. Some of the sighs are in English, but far from all.

The way Osaka Aquarium is built is pretty neat, but I was a bit disappointed. I have had the pleasure of visiting some fantastic aquariums around the world (the one in Monaco is beyond words) and being called the greatest aquarium in Japan and one of the biggest in the world, it did not meet my expectations. The Pacific theme is good and presented well, but the highlight is limited to two whale sharks and some big manta rays. Other than that it is just a few fish, seals and penguins. There are some cool giant spider crabs and a great jellyfish section on the way out though. Even though the center tank is huge I found it very disturbing to watch the whale sharks. Having swam with them in the wild it was quite upsetting to see these huge creatures swimming around and around in a (to them) way too small tank. May be the largest living fish species should not be in an aquarium!

The Osaka Aquarium is very busy and overfilled with children. And with children the tanks get full of fingerprints very early. I have no problem with that, but to see how dirty the tanks were on the inside surprised me. When they take so little care of the cleaning, it makes me wonder how well they take care of the animals!

If you are in the area I guess it´s worth a visit, but I would not go out of my way to do it. It is also a bit pricy.

Whale sharks are a big attraction May 20, 2009
For 2400 yen, you can get a Kaiyu Pass for the day at the Osaka tourist offices (e.g. one in the Namba station) which includes the admission to the aquarium (2000 Yen separately) and unlimited subway in Osaka for the day. The aquarium is in Osaka harbor, a very nice big building, colorfully decorated, there are other sights to see near it too, such as the Suntory Museum and its IMAX theatre. The biggest attraction at this aquarium are the whale sharks. I don't know if any other aquariums in the world had whale sharks, but this is the first time I saw them in person. These were 2 relatively small ones only more than 4 meters long, but they were definitely the biggest fish in the tank! It was very relaxing to watch them swim by, with their school of smaller fish friends.

The aquarium had many tanks, devoted to different areas of the Pacific Rim. the ring of fire. So there is a lot to see. The dolphins were fun to watch too, as were the penguins. Plan to stay about 2 hours at the aquarium.

Wow that's crazy -- the tanks must be huge to contain the whale sharks. Kind of sad that they are confined to a tank though =(
