An old man who were rescued 3days later after earthquake said "we'd reconstruct it all over again".
This old man said "I'm OK because I had experienced Chili-Tsunami" when he was rescued.
Chili-Tsunai that is the Tsunami were caused earthquake happened at Chili in 22nd May 1960, came to Japan 24th May, 22hours later quake, and 124people dead for Tsunami.
Sanriku area that is tohoku area facing the pacific ocean have attacked tsunami many times.
And this old man had experienced world war two,too.
Many Japan's city, Tokyo, Osaka, Hiroshima, Nagasaki and the other cities were burned by bomb at the WWII.
Japanese have reconstructed at the time again and again.
That is why he said "we'd reconstruct it again", I think.
He said in Japanese "mata saiken simashou" at around 1:00 on this movie.
