This is the Okinawa Churaumi Aquarium. After the World’s Fair in Okinawa, Japan, this massive aquarium was opened in 2002 to keep the tourism to the city alive.
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 (an incredible 24 inches thick!). Whale sharks and manta rays are kept amongst many other fish species in the main tank.
Suffice it to say that any fish tank that can hold the largest fish on Earth is pretty amazing. Seeing such giants up close must be as close to a spiritual experience as a godless heathen like me could get.
It also helps that the music with the video above is pretty tear-jerking.
