Two days early but I thought this was amazingly beautiful that I would post it earlier.
Kuroshio Sea is the second largest aquarium in the world. From Wikipedia:
"The aquarium is a part of the Ocean Expo Commemorative National Government Park located in Motobu, Okinawa. The main tank called the ‘Kuroshio Sea’ holds 7,500-cubic meters (1,981,290 gallons) of water and features the world’s second largest acrylic glass panel, measuring 8.2 meters by 22.5 meters with a thickness of 60 centimeters. Whale sharks and manta rays are kept amongst many other fish species in the main tank."
