The shioya ojichan (salt grandfather) is a popular man in Mitsu. Actually, as there are only about seventy residents left, everybody is known by everybody in these days. Shioya ojichan used to make salt all by himself. Today his son helps him. In the morning they fill watertanks with seawater and bring it up to their salt factory. In the video, made by themself, you can see the water beeing boiled and separated from the salt. They are using wood from around this area, as there are a lot of trees.
