What is the size of Japan by area?
Geography of Japan
In November 2008, Japan filed a request to expand its claimed continental shelf.[18] In April 2012, the U.N. Commission on the Limits of the Continental Shelf recognized around 310,000 square kilometres (120,000sqmi) of seabed around Okinotorishima, giving Japan priority over access to seabed resources in nearby areas. According to U.N. Commission on the Limits of the Continental Shelf, the approved expansion is equal to about 82% of Japan's total land area.[18] The People's Republic of China and South Korea have opposed Japan's claim because they view Okinotorishima not as an island, but as a group of rocks.
