List of islands of Japan
Japan is an island country of 14,125 islands, of which approximately 260 are inhabited.<ref name="asahi230215">Template:Cite news</ref><ref>Template:Cite news</ref> Japan is the third-largest island country in the world, behind Indonesia and Madagascar.<ref name="world-atlas">Template:Cite web</ref> Japan is also the second-most-populous island country in the world, only behind Indonesia.
According to a survey conducted by the Japan Coast Guard in 1987, the number of islands in Japan was 6,852. At that time, the survey only counted islands with coastlines of 100 meters or more that were shown on paper maps. On February 28, 2023, the Geospatial Information Authority of Japan announced that the number of islands had been updated to 14,125 through a recount using digital maps. Since there is no international standard for counting islands, only islands with a coastline of 100 meters or more were counted, as in the past. According to the GSI, advances in surveying technology and the detailed representation of topographic features through digital mapping contributed to this announcement.<ref>Template:Cite news</ref><ref name="asahi230215"/>

Former
- South Seas Mandate (1919–1947) - administered by the Empire of Japan as a League of Nations mandate until its defeat in 1945. In 1947, the region was placed under the United Nations trusteeship system as the Trust Territory of the Pacific Islands, administered by the U.S.. The Commonwealth of the Northern Mariana Islands later became a U.S. territory, while Palau, the Marshall Islands, and the Federated States of Micronesia became sovereign independent nations.
- Taiwan and Penghu (1895–1952) - part of the Empire of Japan until its defeat in 1945. Taken over by the Republic of China in 1945 but no treaty of sovereignty transfer has been signed. All claims relinquished by Japan in the Treaty of San Francisco signed in 1951.
- Karafuto (1905–1949) - the southern half of the island of Sakhalin, controlled by Japan after the Russo-Japanese War. Japan lost control of Karafuto after its invasion by the Soviet Union during World War II. Formally abolished as a legal entity by Japan in 1949. Japan in addition controlled the northern half of Sakhalin between 1920 and 1925, during and after the Russian Civil War.
- Jeju Island (1910–1945) - part of Korea, annexed by Japanese colonial empire until its defeat in 1945.
