This seahorse hatchery is totally unique, offering close-up looks at thousands of hatchling seahorses, plus information, videos, souvenirs and a small cafe. One of the exhibits is the only two-headed seahorse ever seen (preserved, as it did not live long). Plans for expansion may mean more to see/do in the future. There are also great walking trails, some tide pools, beaches perfect for shell collecting, and stunning views of Kaimon-dake on a clear day.
Best visited as a stop on your way to Makurazaki or as a day-trip out of Ibusuki.
