An Indigenous group in Taiwan whose traditional communities are located at elevations ranging from approximately 500 to 1500 meters above sea level. With a population of around 7,000, they are one of the Indigenous groups in Taiwan facing the most significant cultural threats. Their most notable traditional cultural activities include the PaSta’ay (Dwarf Spirit Festival), KakawaS (Sky Prayer Festival), and PaSbaki’ (Clan Ancestor Festival). 

The Saisiyat are a traditional patriarchal society, organized into clans based on shared surnames. Their clan names are derived from natural phenomena such as animals, plants, celestial bodies, or physiological phenomena. Major tribal decisions are made collectively by the elders, with each elder managing the affairs of their own clan. This also implies that these clans evolved from a single ancient tribe. Hunting was a major tradition in Saisiyat society, carried out by men according to agricultural needs, seasons, and social events such as marriages and funerals. Ancestors are believed to have come to understand the mountains while seeking game, thereby appreciating the true significance of the forests and mountains.
