Nishihara is a town located in Nakagami District, Okinawa Prefecture, Japan. In the Okinawan language, nishi means "north", as Nishihara was north of the historical Ryukyuan capital of Shuri.

The Okinawan language or Central Okinawan is a Northern Ryukyuan language spoken primarily in the southern half of the island of Okinawa, as well as in the surrounding islands of Kerama, Kumejima, Tonaki, Aguni and a number of smaller peripheral islands. Central Okinawan distinguishes itself from the speech of Northern Okinawa, which is classified independently as the Kunigami language. Both languages are listed by UNESCO as endangered.
