Japanese alphabet looks Jewish

Modern "Hebrew" is a complete reconstruction and doesn't use the ancient Hebrew script, but rather a Babylonian one which was adopted during the captivity in Babylon. Its more likely this is evidence the Japs had contact with Babylonian civilization (which wouldn't be unsurprising because it influenced everything) rather than them being jews, though I believe the ancients thought East Asians were racially Hebrew, but its also possible they are Japhetites who migrated very far from their origin.
