These plates are often grouped with an adjacent principal plate on a tectonic plate world map. For purposes of this list, a microplate is any plate with an area less than 1 million km 2 . Some models identify more minor plates within current orogens (events that lead to a large structural deformation of Earth's lithosphere ) like the Apulian ...
Around 23 million years ago, western Japan was a coastal region of the Eurasia continent. The subducting plates, being deeper than the Eurasian plate, pulled parts of Japan which become modern Chūgoku region and Kyushu eastward, opening the Sea of Japan (simultaneously with the Sea of Okhotsk) around 15-20 million years ago, with likely freshwater lake state before the sea has rushed in.

A map depicting the Japan Trench and its surrounding connections to other relevant trenches. The map was created using GeoMapApp. Topographic map of central Japan, showing location of trenches, tectonic plates and boundaries. The Japan Trench is an oceanic trench part of the Pacific Ring of Fire off northeast Japan.
Japan has 111 active volcanoes. That is 10% of all active volcanoes in the world. Japan has stratovolcanoes near the subduction zones of the tectonic plates. During the 20th century, several new volcanoes emerged, including Shōwa-shinzan on Hokkaido and Myōjin-shō off the Bayonnaise Rocks in the Pacific. [18]
Topographical map of the Sea of Japan. The Sea of Japan represents a back-arc basin that formed via geological rifting of continental crust from the late Oligocene to middle Miocene (28–13 million years ago). [3] The Sea of Japan can be divided into sub-basins; the Japan Basin, Yamato Basin and Tsushima Basin.

The historic Akiha Kodo pilgrimage route (Japan National Route 152) between Suwa-taisha shrine in central Nagano Prefecture and the Akihasan shrine in Shizuoka Prefecture follows the Japan Median Tectonic Line. The Japan Median Tectonic Line Museum in Ōshika is dedicated to the history of and research on the tectonic line. [10]
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
