We visited the Osaka Aquarium Kaiyukan on the 10th day of our 2014-2015 Japan trip. The great thing about our trip to the Kaiyukan was that it was unplanned. Our Japanese family brought us there as a surprise. Because of that, I was not able to research it hence I don't have any background about what to see and expect in the Kaiyukan.

You gotta love its facade.
