An aquarium in Yamagata Prefecture that once faced bankruptcy has turned its fortunes around by focusing on jellyfish, exhibiting the world's largest variety of the gelatinous aquatic creatures in captivity.
The Kamo Aquarium in Tsuruoka displays more than 35 species of jellyfish in an underground exhibition area called the Kuranetarium, a play on words incorporating the Japanese word for jellyfish, "kurage," and planetarium.
Guinness World Records has recognized the aquarium as having the largest number of jellyfish species in its collection.
