The aquarium was established through a partnership with local commercial fishermen who provide rare deep-sea specimens caught in their nets.
It holds one of the world's most comprehensive collections of live crustaceans, often collaborating with universities for research purposes.
Some displayed species are so rare they have only been documented through the collection efforts of this specific aquarium.
The aquarium frequently displays giant isopods, a deep-sea scavenger often called the 'cockroach of the sea'.
Visitors can observe the molting process, a critical biological stage for crab growth, which is rarely visible in other public exhibits.
The Ebitokanino (Shrimp & Crab) Aquarium in Susami, Wakayama, is a unique research-focused facility dedicated exclusively to crustaceans. It houses one of the world's largest collections of crab and shrimp species, featuring over 150 different varieties. The aquarium functions as a branch of the Susami Town Marine Research Institute, focusing on the biodiversity of the Kii Peninsula. Exhibits showcase rare deep-sea specimens caught by local fishermen off the coast of Susami. Tanks are organized to highlight specific habitats ranging from shallow tropical reefs to the cold, dark depths of the Pacific Ocean. Many of the displayed creatures are rarely seen in standard public aquariums due to their specialized environmental needs. The facility provides detailed educational information regarding the lifecycle, molting, and anatomy of crustaceans.

Look for the display tanks at lower levels, as many crab species are naturally benthic and prefer to stay near the bottom.
Ask the staff about the 'catch of the day', as the exhibits are updated whenever local fishermen retrieve new, unique specimens.
Do not tap on the aquarium glass, as crustacean behavior and stress levels are highly sensitive to external vibrations.
Closed on Thursdays; if a national holiday falls on a Thursday, the aquarium remains open and may close the following day instead.
