This park is more than just a pretty spot to take in the sunset – it is also an important historical site. After a crushing defeat in battle, a group of samurai fled to Amami Oshima, and posted guards on both sides of the entrance to Kasari Bay to keep watch for invasion. The Gamozaki Shrine honors Gamo Zaemon, one of the samurai soldiers who served here. The ocean views from the top of the observatory park are well worth the climb.
