The Kamo Aquarium (Tohoku Epson Aquarium Kamosui) in Imaizumi, Tsuruoka, Yamagata. With the renewal in April 2026, the jellyfish exhibit grew to 100 kinds. In the large tank "Jellyfish Dream Theater," ten thousand moon jellyfish drift, and at Hireashi Square you can see California sea lions and spotted seals up close. At the restaurant and snack corner inside you can taste jellyfish dishes and jellyfish soft serve.
