It is located at the eastern end of Makira (San Cristobal), separated from it by a 7.5 km wide strait, and just north of smaller Owariki (Santa Catalina).

The inhabitants of Owaraha speak the Owa language and share the same culture with the people in Owariki and in the eastern end of Makira Island.

The Pagewa and Aiga Tatari clans of Owaraha and other nearby islands claim descent from the refugees from Teonimanu which was washed away.

More precisely the sighting and also landing in Owahara was due to a local voyage done by a small boat, in the accounts the brigantine Santiago, commanded by Francisco Muñoz Rico and having Hernán Gallego as pilot.

Küper was married to a respectable local woman, Kafagamurirongo, and was the only white who ever reached the arafa (high person) status within a Melanesian community.
