Also known as dream weaver having a significant number of followers of Islam, it is considered as one of the 13 Moro groups in the Philippines. The Yakans mainly reside in Basilan but are also in Zamboanga City. They speak a language known as Bissa Yakan, which has characteristics of both Sama-Bajau Sinama and Tausug (Jundam 1983: 7-8). It is written in the Malayan Arabic script, with adaptations to sounds not present in Arabic (Sherfan 1976).

The Yakan have a traditional horse culture. They are renowned for their weaving traditions.[4] Culturally, they are Sama people who eventually led a life on land, mostly in Basilan and Zamboanga city. They are included as part of the Sama ethnic group, which includes the Bajau, Dilaut, Kalibugan, and other Sama groups.[5]
