Susami Crustacean Aquarium

Located in Susami on the southern side of the Kii Peninsula, this aquarium is one of the few in Japan specializing in crustaceans. Adjacent to the Susami roadside station, the aquarium occupies the gymnasium of the former Esumi Junior High School and displays approximately 1,000 specimens representing 200 species, primarily shrimp and crabs found in the waters around the Kii Peninsula.

At the entrance, visitors are greeted by a large tank inspired by the waters off Susami, known for its underwater mailbox. The unusual sight of various species of moray eels gathered together immediately catches the eye. The aquarium displays crustaceans from Japan and around the world, including Japanese spiny lobsters and other lobsters. At the touch pool, visitors can interact with Japanese spider crabs, among the world’s largest crabs, and horseshoe crabs, often called living fossils.

The aquarium also features marine animals other than crustaceans, including sea turtles, sharks, penguins, and jellyfish. The sea turtle feeding experience is also popular. The aquarium also drew attention for becoming the first in the world to exhibit the panda amphipod, named for its black-and-white markings reminiscent of a panda. Special seasonal exhibits are held for occasions such as Children’s Day, Christmas, and New Year, offering something new to discover with each visit.
