方法がとれていた。2. Description of the Related Art In recent years, with the abolition of the salt monopoly law, various natural salts have been produced. In Japan, as in other countries, it is difficult to produce solar salt using a vast salt field, so salt can be produced directly from seawater, as seen in the traditional Irihama-type and down-flow-type salt fields. Instead of producing, a method has been adopted in which seawater is once concentrated to form a concentrated salt water, and the concentrated salt water is again evaporated in the sun or heated to crystallize.
