Salmon must have been an important source of food for the Jomon people. They most likely caught and preserved, by different means such as smoking, enormous numbers of salmon that swim upstream in a particular season each year.

The salmon and trout that go south to Chiba on the Pacific coast and to Yamaguchi on the Japan Sea coast were the blessings of nature that sustained the Jomon society in eastern Japan.
