The Hamahiga salt factory is located at the southern tip of Hamahiga island which is connected to the main island of Okinawa by a bridge. The factory is located near a pristine private beach where it sources its saltwater from. The water is first run trough a large evaporator outside where a large fraction of the water is evaporated before being boiled indoors to further increase the salt concentration. The factory has a small gift store outside offering a variety of salt products and sometimes offers guided tours when the workers are not too busy processing the salt.
