Footage filmed on 13 March of Miyagi and Iwate prefectures shows flattened buildings, fires still burning and stranded ships.
Police have warned that the death toll in tsunami-hit Miyagi prefecture alone could exceed 10,000.
The tsunami that followed the 8.9-magnitude earthquake wreaked havoc along a huge stretch of Japan's north-east coast, sweeping far inland and devastating a number of towns and villages. Powerful aftershocks are continuing to hit the region.
