The extreme points of Japan include the coordinates that are farthest north, south, east and west in Japan, and the ones that are at the highest and the lowest elevations in the country. Japan's northernmost point is disputed, as both Japan and Russia have claimed Iturup, the island on which Japan claims the point is located. The southernmost point is Okinotorishima; the western-most is Cape Irizaki in Okinawa Prefecture, and the eastern-most is Minami Torishima. The highest point in Japan is the summit of Mount Fuji at 3,776 metres (12,388 ft). At 150 m (492 ft) below sea level, the bottom of Hachinohe mine is the country's lowest point. The surface of Hachirōgata is Japan's lowest natural point at 4 m (13 ft) below sea level. With the exception of Cape Irizaki, the western-most location of Japan, all other extreme locations are uninhabited.
The northernmost point that Japan claims lies on the disputed island of Iturup. Japan's claim to the three southern-most islands of the Kuril Islands is disputed by Russia, who currently controls the islands. This list provides the northernmost point as claimed by Japan as well as the northern-most undisputed point in Japan.
