Aogashima
Aogashima is a volcanic Japanese island in the Philippine Sea, located 222 mi south of Tokyo. The island’s area is 3.38 sq mi and, as of 2014, its population is 170.
While the history of human settlement in Aogashima is uncertain, the island is mentioned in records that recorded volcanic activity in the 1600s, so we think that it has been populated for at least 400 years.
