Kamo Aquarium

Kamo Aquarium, located in Tsuruoka City of Yamagata Prefecture, Japan, is a unique marine attraction renowned for housing the world’s most extensive collection of jellyfish species. Often referred to as the “Jellyfish Dream House,” the aquarium features mesmerising displays of over 60 jellyfish varieties, beautifully illuminated in circular tanks that offer a hypnotic visual experience. Visitors can explore these delicate sea creatures' science and life cycle, including the fascinating process of strobilation—the budding and development of new jellyfish. The crown jewel of the aquarium is the Jellyfish Dream Theatre, a massive tank filled with hundreds of floating jellyfish, set against ambient lighting and soothing music, creating a surreal underwater ambience. Beyond jellyfish, Kamo Aquarium exhibits local marine life from the Sea of Japan and offers interactive experiences such as feeding harbour seals and observing sea lion performances. The aquarium plays a vital role in jellyfish research and conservation, and its dedicated staff have transformed it from near bankruptcy into a globally recognised institution. A visit to Kamo Aquarium is entertaining and educational, offering insight into marine biodiversity and the mysterious world of jellyfish in an unforgettable, family-friendly setting.
