The Japanese archipelago (日本列島, cultural language: Japanese archipelago) is an archipelago located in Northeast Asia, a territory of Japan. It consists of 6,852 islands. Because the Japanese archipelago stretches very long from north to south, the highest temperature is 42 degrees Celsius and the lowest temperature is minus 44 degrees Celsius. Also, the Japanese archipelago is surrounded by seas such as the Sea of ​​Japan, the Sea of ​​Okhotsk, and the Pacific Ocean. On the Pacific side of the archipelago, deep trenches such as the Kuril-Kamchatka Trench and the Japan Trench are formed, and the entire trench is active in tectonic fluctuations and orogeny. It is also known that about 10% of the volcanoes found on Earth are in the Japanese archipelago. Geologically, it lies east of the Eurasian plate and southwest of the North American plate. Under these two continental plates, two ocean plates, the Pacific plate and the Philippine Sea plate, subside, so it is presumed that they became an arcuate archipelago separated from the Eurasian continent.

Formation process


The four main islands that usually make up the Japanese archipelago are Hokkaido, Honshu, Shikoku, and Kyushu. In addition, it includes various annexed islands, the Nansei Islands and the Ogasawara Islands. However, in a broader geographical sense, the Japanese archipelago also includes the following islands and their annexed islands. Kuril Islands Sakhalin Island Taiwan Island

Main Islands of the Japanese Archipelago

However, the islands in parentheses are claimed by Japan, but are effectively controlled by Russia. Strictly speaking, Iturup Island and Kunashir Island belong to the Kuril Islands, not the Japanese Archipelago, and Okinawa Island and Amamio Island belong to the Nansei Islands.
