Japan discovers 7,200 new islands in its territorial waters

New mapping of Japan’s land mass has uncovered the nation’s 7,000 beforehand unknown islands. Because the Japanese authorities completes its first official survey of its territorial waters since 1987, the official variety of Japan’s islands is anticipated to quadruple, from 6,852 to 14,125, with the inclusion of seven,272 further islands, as reported by native information.

Japan’s complete landmass is not going to develop in keeping with the outcomes of a latest evaluation by the nation’s Geospatial Data Authority.

In accordance with native information, a member of Japan’s governing Liberal Democratic Occasion was the impetus for this. A member of the get together in December 2021 mentioned that the nation’s Parliament wanted a extra exact rely of the islets for the reason that out there data was outdated. They deemed it a “essential administrative problem referring to the nationwide curiosity.”

The New York Submit as a substitute claims that it could present authorities with a extra exact map of Japan.

Way of life Asia reviews that the research discovered greater than 100,000 islands. However solely these with a diameter of 100 metres or extra had been counted.

This can permit the Japanese authorities to extra exactly map the nation. All textbooks, authorities publications, and different reference supplies will must be revised to mirror the latest estimates of the variety of islets. Present projections put Japan’s inhabitants at about 124,840,000 and put the nation’s complete space at roughly 146,000 sq. miles.

Due to Japan’s frequent volcanic exercise and extreme climate, the discovering of latest isle just isn’t all that surprising. Geographers have beforehand recorded the delivery of latest islands and the lack of others.

Native media in Japan have reported that the variety of islands formally recognised by the nation would improve by 7 thousand. In 1987, the Japan Coast Guard disclosed this data, prompting the Japanese authorities to carry out its first official territorial retally in virtually a century.

The official complete, which is projected to develop from 6,852 to 14,125, will probably be introduced in March. Japan’s landmass and unique financial zone will stay unchanged. The Japanese authorities’s geospatial information authority, GSI, may be very near issuing the ultimate report on the matter.


A extra in-depth familiarity with the nation’s landmasses could also be attributed to improved cartographic accuracy and technical growth. All textbooks and official reviews will probably be revised to mirror the brand new information. The pc recognized greater than 100 thousand islands, however solely these with diameters of 100 metres or extra had been thought-about.

By definition, an island is “a naturally created area of land, surrounded by water, that’s above water at excessive tide,” as acknowledged by the United Nations. This factored in whereas deciding what number of islands to incorporate. Media sources point out that there have been an estimated 1,479 islands in Nagasaki prefecture and 1,256 islands in Kagoshima prefecture. There have been 1,473 islands that made up Hokkaido, a area in northern Japan.
