Excellent displays, very extensive. Reportedly one of the five best aquaria in the world. Would not honour advertised discount in "Discounted sightseeing Spots List" brochure.

You save about 200-300 yen. Enterance 2300. Subway will cost 200-300 each way. They have a smaller whale shark now, no more sun fish. Hammerhead and manta. Alot to see , get to touch shark n stringray at the end. Would take you 1-1.5 hrs to see the fish.

I arrived at Kaiyukan in the evening. It was not so crowded and quiet. Lights were low like the night sea. We touched the pink sharks and rays. Good experiences.

We loved how this aquarium has to explore the different levels of seal life by spiralling down around a centre tank. It was quite busy when we were there but the crowds flowed fairly well. We opted for the tranist/aquarium combo pass and saved a few thousand yen.

It's a nice aquarium, nothing fancy but too crowded during Spring so the experience isn't that great.

We got a Kaiyu Pass $25 entry plus all day on the Subway - just got the pass from the Station Master Office at Namba, really good value especially we used the subway all day.... aquarium was interesting well laid out.

This is a world class aquarium, and well worth a detour. The whale shark was epic, and its 5000 tonne tank equally so.

3 stations then change to subway for 2 stations from the Osaka station. Lots of animals to see. Variety of restaurants in the area, also a big ferris wheel which was great to ride on.

One of the best! It's a must go if you are planning to go to Osaka. Not only mammals and fishes, there are other educational stuff to see too. Live interactions and introductions of certain species. I will go there again if I'm going to Osaka the next time. Best to go during off-peak season.
