After World WarⅡ（post 1945）,
the American occupation army came to Japan and soldiers surfed fiberglass longboards
at Kamakura, Karatsu and beaches around the military bases.
But before that, Japan already had a traditional culture of surfing over 100 years old.
Like the Polynesians, Japanese people subsisted off the bounties of the sea
where they, too, discovered how to ride waves in the ocean.
