Forty-two survivors have been pulled from the rubble in the flattened town of Minami Sanrik, where up to 10,000 people are feared to have perished.
Around half the town's 18,000 residents are missing but search and rescue teams are still working desperately through the rubble to try and find more people.
Police are also trying to stop people returning to their homes.
Despite the first tsunami warning being issued to the town that lies two miles from the coastline, some residents decided to stay in their homes instead of fleeing – leading to the high number of missing people, CNN reported today..
Most of the houses in Minami Sanriku have been completely flattened and waterlogged and one house was found even with seaweed inside.
