Tofugu has a short article on this unusual and beautiful Japanese island: Aogashima.
Aogashima (“blue island”) 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. Volcanic islands? Not typically what comes to mind when you think of Tokyo.A fellow named Izuyan has been traveling to isolated islands of Japan and taking excellent photos. See: Flickr set for Aogashima.
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.
There are two ways on and off the island: by helicopter or by boat. There’s only one, small harbor where the boats go in an out of, and it seems to be a little unreliable. Because Aogashima is so remote and isolated, it can sometimes be hard to get a boat to or from the island safely.
