Nii Ōshima (新居大島), or sometimes just Ōshima (大島), is an inhabited island located roughly 1.5 kilometers northeast of the city of Niihama (which it is officially a part of) in Ehime Prefecture, Japan. Nii Ōshima is located in the Seto Inland Sea. It has a circumference of approximately 8 kilometers and a total area of 2.13 square kilometres (0.82 sq mi). The island is mostly hilly, with its highest point at 146.48 meters above sea level. The northern part of the island is covered with dense forests, has many cliffs. The main settlement is in the southern part of the island. There is a ferry that runs between Nii Ōshima and Niihama approximately once every hour, taking fifteen minutes to complete a one-way journey. At one point, there was the possibility that a bridge might be built to connect Ōshima and Shikoku, but these plans are now considered unlikely. There is no public transportation on the island, but there is a road that circles the island. | ||||||
