Yapen
Yapen denotes the peoples of Yapen, a large mountainous island in Cenderawasih Bay off northern New Guinea, among them the Serui and Ansus communities of the coast; the island is unusually mixed in language, home both to Austronesian Yapen languages and to the Papuan Yawa tongues of its central districts. The Spanish navigator Álvaro de Saavedra made the first recorded European landing there in 1528 while sailing back from Tidore.
