【日本の正体】日本列島は「2つ」に割れていた？東西を真っ二つに裂く巨大な溝「フォッサマグナ」と、食や言葉が違う本当の理由。

The Japanese archipelago, which we walk on every day, actually didn't exist until just "yesterday" in the context of Earth's 4.6 billion-year history. [cite: 1] Just 20 million years ago, Japan didn't exist as an island; it was simply a part of the landmass attached to the edge of the vast Asian continent. [cite: 1] Even when dinosaurs roamed Fukui and Hyogo prefectures, that area was still a "continent." [cite: 4] However, about 25 million years ago, a massive upheaval occurred deep beneath the Earth's surface. [cite: 6] The edge of the continent slowly but surely began to tear apart, and seawater flowed into the huge crack. [cite: 6] This was the birth of the "Sea of ​​Japan." [cite: 1, 6] Even more surprisingly, it is said that present-day Hokkaido was originally "two completely separate islands" that collided due to the force of tectonic plates and became one (the boundary of that collision is the Hidaka Mountains). [cite: 19] Japan, a miraculous place where rocks that have traveled thousands of kilometers have come together and where four rare tectonic plates collide [cite: 2, 15]. This time, we present the magnificent 4.6 billion year story of the birth of the Japanese archipelago, depicted on an unimaginable scale: continents being torn apart, volcanoes erupting, and oceans being born. #BirthoftheJapaneseArchipelago #Geology #JapaneseHistory #EarthScience #AncientHistory #HistoricalMystery #BuratamoriStyle #Documentary #BirthoftheJapaneseArchipelago #FossaMagna #Geology #BuratamoriStyle #HistoricalMystery #AncientHistory #EarthScience
