Located in Hado Cape, the Genkai Sea Observatory tower offers incredible views from multiple perspectives. By traversing the 90-meter pier, guests arrive to the deck of the tower. From the deck, you can throw food to the fish and watch them excitedly swim around. Looking up presents you with a view of the beautiful islands surrounding the cape. Descending the stairs into the tower grants you a special look into the lives of the 30 different species of fish that call the Genkai Sea home. Visitors can watch as they swim around the seaweed and shellfish. Thanks in part to the confluence of the Japan and the Tsushima currents, many tropical fish inhabit this area.
