Why was Englnad overrun and Japan was not? -

Japan, on the other hand, is an island, and believe me -- the Pacific Ocean and Sea of Japan are not friendly bodies of water to try sailing in for conquest.

Actually, the last time England was invaded and conquered was 1066. A lot has to do with location
