Salt workshop in Murakami City, Niigata Prefecture. Seawater is suctioned via pump from the nearby Japan Sea to the flat tank outside the building. The seawater is concentrated by a factor of 8 and then boiled in this building to precipitate salt. When the steam caused by warming the seawater touches the roof, it is cooled and returns to water. A tray is placed under the roof to prevent this water from mixing with the salt. The roof is a polycarbonate corrugated sheet, which can be used as a light source during work.
