The population of Aragusuku Island (Aragusuku-jima) is approximately 6 people! The island is called "Panari" by locals because it means "separated". Aragusuku is actually made up of two separate islands that are connected by a coral shoal. During low tide, you can actually walk between the two islands. This area was once home to Dugong which are manatee looking mammals. The locals would catch these dugong and use them to pay their taxes to the Ryukyu Government.
Aragusuku is located right next to Iriomote Island. The only way to get to these islands is via a private tour company. Aragusuku Island has an excellent coral reef for snorkeling as well as an interesting village to explore. The island is still home to many houses, most of which are uninhabited. The island of Aragusuku was once heavily populated and even had a school. The island has its own type of pottery called Panari-yaki which was made until about 150 years ago. It is said that a great deal of the population was killed in a large tsunami that occurred long ago. As the population became older, many people moved away to neighboring islands.
