This is the only facility in the world with the horseshoe crab as its theme. It is involved in protecting the “Horseshoe Crab Breeding Grounds,” a Nationally-Designated Natural Monument, and researching the crab as a species. From “larvae” (baby crabs) to adult crabs, the museum affords visitors a rare opportunity to observe horseshoe crabs up close.

Observe Living Horseshoe Crabs

Live horseshoe crabs, a species known as “living fossils” which has survived for 200 million years, are being kept here. You can view them up close.

Learn About Horseshoe Crabs

A lot can be learned about horseshoe crabs from the various exhibits. On the large-screen in the 80-seat Horseshoe Crab Theater, the museum’s mascot, “Kabuni-kun,” teaches visitors about the crab in a fun way.

Exhibits of Dinosaur Skeletal Specimens

On display are a variety of dinosaur skeletal specimens and other exhibits of creatures living during the same period in time. The replicas of the Baryonyx which move and roar are a thrilling sight.
