Members of the Japanese coast guard spotted a dog alive on the rooftop debris of a home swept out to sea three weeks after a devastating 9.0 magnitude earthquake and a 30-foot fall tsunami wave struck the island nation.

Remarkably, the dog was in good health, and you can see in the video that he was more than eager to eat treats offered by the coast guard.

His discolored collar gave no clues clues as to his owner.

The dog has without question become a national hero in Japan, bringing hope to many who desperately need it.
