Joedu City Aquarium Umigatari is a municipal aquarium located in Gochi, Joetsu City, Niigata Prefecture. Following a major renewal in June 2018, it was reborn under its current name. Situated right along the coast of the Sea of Japan, the facility houses approximately 300 species and 45,000 individual marine organisms. A standout feature is the Magellanic penguin exhibit, which boasts one of the largest populations in the world, alongside spectacular performances by bottlenose dolphins that captivate visitors of all ages.
The origins of this institution date back to 1934, reflecting a long history of marine research and public engagement in the region. Through its 2018 revitalization, the aquarium was transformed into the modern 'Umigatari' experience. The facility is a three-story structure that serves both as a public attraction and a center for the display and study of marine life, deeply rooted in the local coastal culture.

Inside the aquarium, you will find the 'Magellanic Penguin Museum,' a dedicated space where you can observe these charming birds up close. The museum hosts a significant number of individuals, allowing for a deep look into their natural behaviors. Another highlight is the bottlenose dolphin performance, which offers a high-energy, rhythmic display of intelligence and grace. The diverse exhibits throughout the building are designed to educate visitors on the incredible variety and complexity of marine ecosystems.
The aquarium is generally open from 10:00 AM to 5:00 PM. Please note that hours may vary depending on the season or specific dates, so it is highly recommended to check the official schedule before your visit. While dolphin performances and penguin viewing are available year-round, the specific timing of events and the types of animals on display may change based on the season, weather conditions, or scheduled maintenance.

At the Magellanic Penguin Museum, visitors can engage with exhibits focused on the ecology and lifestyle of these penguins. The bottlenose dolphin shows are a must-see, providing a sense of dynamic movement and energy that is unique to a professional aquarium setting. These programs are the core experiences that make a visit to Umigatari truly memorable.
The aquarium is located in the Naoetsu district of Jo_etsu City, an area characterized by its beautiful coastline. The surrounding area offers plenty of sightseeing opportunities, where you can enjoy the scenic views of the Sea of Japan. The area is easily accessible via car or local bus, connecting you to other nearby coastal attractions.
