Tucked away in a fairly rural area of Japan lies the world’s largest collection of jellyfish. Kamo Aquarium which is located near to moderate-sized city of Tsuruoka in Yamagata, is home to 60 species of these invertebrates. The aquarium is recognized by the Guinness World Records. 

By far the most impressive feature is the Jellyfish Dream Theater, a five-meter tank with approximately 10,000 moon jellies drifting in the saline water. Dramatic backlighting makes from especially haunting photographs.

Visitors can also check out the onsite laboratory used for breeding jellyfish. Check out the small jellies underneath a microscope. While jellyfish are certainly the main draw, there are also several species of octopus, rays, and seals, which perform in regularly scheduled shows. At the end of your visit, swing by the restaurant, which has jellyfish on the menu.
