The aquarium holds the largest number of Magellanic penguins globally, maintaining them in a specialized enclosure that allows visitors to observe them from both above and below water.
The design of the main stadium creates an optical illusion where the dolphin pool appears to blend seamlessly into the Sea of Japan behind it.
The facility uses a centralized filtration system that continuously circulates water directly from the adjacent Sea of Japan to maintain high-quality marine environments.
The architecture features a vertical layout that mimics the descent from the coastline down to the seabed of the Sea of Japan.
The aquarium is a primary hub for local conservation efforts regarding the biodiversity of the Niigata coastline.
Jōetsu Aquarium Umigatari is a large-scale aquarium located on the coast of the Sea of Japan, featuring an open-air dolphin performance stadium that visually integrates with the horizon. The facility features a multi-level 'Umigatari Tube,' an underwater tunnel allowing 360-degree views of local marine life. It houses the largest collection of Magellanic penguins in the world, showcased in an environment designed to replicate their natural coastal habitat. A signature highlight is the 'Grand Terrace,' an observation deck positioned directly above the ocean that provides unobstructed views of the sea. The exhibits are arranged to follow the theme of the ocean journey from the shoreline to the deep sea. The facility includes a dedicated jellyfish gallery with immersive lighting displays. It is a modern facility that replaced the original municipal aquarium on the same site in 2018.

Arrive at the dolphin stadium 20 minutes before shows to secure a seat, as they fill up quickly during peak days.
Bring a change of clothes if you sit in the front rows of the dolphin stadium, as water spray is common.
Visit the penguin enclosure during feeding times for the highest level of animal activity.
Avoid arriving during public holidays or the Obon period if you prefer a quiet experience, as the facility becomes significantly crowded.
Open daily throughout the year, though periodically closed for occasional facility maintenance days.
Refrain from using flash photography, as it distresses the animals. Do not tap on the aquarium glass.
