Sabu Island is also known as Sawu or Savu. Residents on this island themselves call their island as Rai Hawu which means Land of Hawu and the Sabu people themselves call themselves as Do Hawu. The official name used by the local government is Sabu. The Sabu people explain that the name of the island comes from the name Hawu Ga, which is the name of one of their ancestors who is considered to have first visited the island. This may also be related to local linguistic characters that do not recognize the pronunciation of the letters s, f and v.

According to history, the ancestors of the Sabu people came from a very distant country which is located in the west of the island of Sabu. In the 3rd century until the 4th century there was a fairly large population movement from South India to the Archipelago. The migration was due to the fact that at that time there was a prolonged war in South India. From ancient poems in the Sabu language, historical information can be obtained about the country of origin of the Sabu ancestors. The poems reveal that the land of origin of the Sabu people is located very far across the ocean to the west called Hura. In India there is Surat City in the South Gujarat region which is located next to Bombay City, Cambay Bay, South India. The city of Gujarat at that time was already famous as a trading center in South India. The Sabu people cannot pronounce the words Surat and Gujarati properly, so they call it Hura. These immigrants from South India became the first inhabitants of Raijua Island under the leadership of Kika Ga and his brother Hawu Ga. The descendants of Kika Ga are called the Sabu people (Do Hawu). After mating, they then spread on the islands of Sabu and Raijua and became the forerunner of the Sabu people.
