Aogashima is a tropical, volcanic island in the Phillipine Sea. Despite being over 200 miles away from the country’s capital, Aogashima is governed by Tokyo. In fact, a whole stretch of tropical and sometimes uninhabited islands called the Izu Islands are technically part of Tokyo. As you might imagine, Aogashima isn’t the most crowded place in the world. As of this year, only about 200 people live on Aogashima. The island only has one post office and one school.
