Answer:

Japanese archipelago separated and became isolated from China around 11,000BC. Archaeological evidence indicates that Stone Age people lived in the Japanese archipelago during the Paleolithic period between 39,000 and 21,000 years ago. Japan was then connected to mainland Asia by at least one land bridge, and nomadic hunter-gatherers crossed to Japan from East Asia, Siberia, and possibly Kamchatka. Flint tools and bony implements of this era have been excavatedin Japan.
