However the main tank is also quite beautiful, the whole aquarium doesn't compete to the Kaiyukan in Osaka. If you've been to this world-class aquarium, you can't help but compare the two and Osaka wins on every point. Except maybe that the one in Osaka is closed 7 days in the year and Kyoto has not even one closing day!
It doesn't mean I would advise against visiting the Kyoto aquarium. The animals like jelly fish, sea stars, lobsters and other exotic sea creatures like Japans 'living fossil', the giant salamander, are riveting to watch. And I did like the 'jelly fish lab' and the way you could peer down in many basins, to see the fish from above and up close. Something that could never occur in the west, because people would always try to touch the animals. Japanese are more sensible than that and just leave the fish be. One of the reasons it's so utterly amazing to spend time in Japan!
Visiting the aquarium is, from another perspective, maybe not without reserve. It is at least one the most discussed building projects between Kyoto residents of the last years. Why the anti-aquarium network fought hard against the building of the new 'should be tourist attraction' are in short these reasons: Osaka has a world-class aquarium, which is just an hour away and is next to the ocean (which Kyoto is not). Also the loss of public green space, politics and environmental reasons are on the groups agenda. The last point because some of the fish held in the aquarium might experience stress. However hard they have fought, they did not win. Visiting the aquarium, for me, was not a political decision. And whether it was right or wrong to build this tourist attraction it is not for me to decide, as an outsider. But I feel for the anti-aquarium network and their arguments sound proper. I think everyone should decide for themselves.
