NHK said about 30 troops were to head for the site of the quake to give assistance.
TV footage showed collapsed wooden houses, tiles from roofs scattered on narrow streets and a man digging through piles of boards from a collapsed house in Wajima.
Anxious residents gathered outside their homes in Wajima, some holding children in their arms.
"Books fell off bookshelves and it was the worst shaking I have ever felt," one local official told NHK.
Aftershocks are still expected....hope they'll be on the mild side.
