Organisms of the Japanese Islands
Through the repetition of glacial and interglacial cycles dating back about 1.7 million years, the variety of these living organisms migrated from the continent to the Japanese Islands by crossing the strait, which had turned into land during the glacial stage. During the interglacial stage, when they were cut off from the continent by the ocean, these living organisms achieved their unique differentiation as they adapted to the transformation of the natural environment of the Japanese Islands, with its varied climate and complex topography.
