Overview

Toba Aquarium is one of Japan’s largest and most comprehensive aquariums, located in the coastal city of Toba, Mie Prefecture. Facing Toba Bay, the aquarium is widely regarded as one of the best in the country due to its exceptional species diversity, spacious exhibits, and visitor-friendly layout.

Unlike many aquariums that focus mainly on regional marine life, Toba Aquarium showcases creatures from rivers, oceans, polar regions, and tropical environments around the world, making it an ideal destination for international travelers of all ages.

History and Background

Toba Aquarium opened in 1955 and has steadily expanded over the decades. Its guiding philosophy is to display aquatic life in environments that closely resemble natural habitats while remaining accessible and educational for visitors.

The aquarium is closely connected to the maritime culture of the Ise–Shima region, an area historically dependent on fishing, pearl cultivation, and coastal trade.

Scale and Collection

Toba Aquarium is known for its extraordinary scope.

Key facts:

• Over 1,200 species

• Approximately 30,000 individual animals

• One of the highest species counts of any aquarium in Japan

The facility is spread across multiple large buildings, allowing visitors to explore at their own pace without feeling crowded.

Unique Exhibit Concept

Unlike traditional aquariums organized strictly by geographic zones, Toba Aquarium uses themed exhibition areas that emphasize behavior, environment, and adaptation.

This approach allows visitors to compare different species across ecosystems and better understand how aquatic animals survive in diverse conditions.

Major Exhibition Areas

Japan’s Rivers and Coastal Seas

This area introduces freshwater and coastal species native to Japan, helping visitors understand the ecological foundations of Japanese food culture and fishing traditions.

Polar and Cold Regions

Home to animals adapted to extreme cold, this zone highlights survival strategies such as thick blubber, streamlined bodies, and social behavior.

Tropical Seas and Coral Reefs

Brightly colored fish, coral displays, and warm-water species create a striking contrast to colder environments, offering insight into biodiversity in tropical oceans.

Aquatic Animals of the World

This section includes species from lakes, rivers, and oceans across multiple continents, emphasizing global aquatic diversity.

Dugong: The Aquarium’s Symbol

Toba Aquarium is internationally famous as one of the few places in the world where visitors can see a Dugong in captivity.

The dugong, a rare marine mammal related to manatees, is displayed in a calm, carefully managed environment. This exhibit plays an important role in conservation education, as dugongs are endangered due to habitat loss and human activity.

For many visitors, this exhibit alone is a major reason to visit Toba Aquarium.

Sea Otters and Other Highlights

Another popular attraction is the aquarium’s Sea Otter exhibit. Sea otters are known for their intelligence, tool use, and playful behavior, making them especially appealing to families and first-time aquarium visitors.

Other notable animals include:

• Walruses

• Seals and sea lions

• Penguins

• Large sharks and rays

Each exhibit is designed to allow clear viewing while minimizing stress for the animals.

Educational Approach

Toba Aquarium places strong emphasis on education.

Features include:

• Multilingual information panels

• Staff-led feeding times with explanations

• Clear descriptions of animal behavior and conservation challenges

Rather than relying heavily on shows, the aquarium focuses on observation and understanding, encouraging visitors to learn through quiet viewing.

Visitor Experience and Layout

The aquarium is designed as a barrier-free facility with gentle slopes and wide corridors.

Visitors can:

• Choose their own route through the exhibits

• Revisit favorite areas easily

• Spend several hours without retracing steps

Indoor exhibits make the aquarium suitable for visits in all weather conditions.
