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.
The cave of Shirumichu is though of being the place where gods Shirumichu and Amamichu, the creator gods of Okinawa, gave their first birth. It is now a popular place to pray for pregnancy and safe delivery.
This small piece of land attached to the island of Hamahiga in Okinawa is a sacred site of the Ryukyu religion. It is known as the tomb of Amamichu, the creator god of Okinawa. A small shrine on the island is dedicated to the god.
