Historically, there are various transliteration terms for Pinuyumayan in traditional Mandarin Chinese. The term Pinuyumayan originates from the name “Pinuyumayan” of the Nanwang village (Sakuban village) of Beinan Township in Taitung. To distinguish the term as the demonym of the ethnic group from the term for the specific tribe of the group, some Pinuyumayan people have suggested the term “Pinuyumayan” as a new name.
There are two sources regarding the origin of the Pinuyumayan: “bamboo-born” and “stone-born”. The former comes mainly from people of the Pinuyumayan tribe, while the latter from those of the Zhiben tribe. The other tribes of Pinuyumayan also develop from these two main tribes after migration and resettlement. The Pinuyumayan people was a powerful ethnic group before the 17th century and reached a peak during the Pinadray period. As a leader respected by all tribes, it is said that the Sakuban led 72 tribes from different ethnic groups in eastern Taiwan, with influence reaching Yuli (Posko) Township in Hualien in the north and Hengchun Township in Pingtung.
In the 18th century, some of the clans migrated to the Hengchun Peninsula; they settled down successfully and extended the community to the south, such migration is called “sukaro”, which suggests “sitting in a sedan-chair” or “carried by people” in Paiwan language. During the Japanese colonization beginning at the end of the 19th century, the Pinuyumayan were ethnologically called the “Pinuyumayan” because they had eight tribes, known as the “eight-tribe indigenous people”. Today, Taitung City and Beinan (Pinuyumayan) Township in the Taitung Plain are the center of the Pinuyumayan. Some of them settled in Chenggong Town (Madawdaw) and Taimali Township (Tjavualji). Major tribes include the Zhiben (Katratripulr), Jianhe (Kasavakan), Nanwang (Sakuban), and Baosang (Apapolo) in Taitung City; and the Lijia (Ligavon, in Lijia Village), Taian (Tamalakau, Taiping Village in Taian Township), Shangbinlang (Alripay, in Binlang Village), Shabinlang (Pinaski, in Binlang Village), Chulu (Ulivelivek, in Chulu Village), Danadanaw (in Mingfeng Village), and Banjiu (combined with the Chulu) in Beinan Township. Currently, many Pinuyumayan have moved away from eastern Taiwan for development in the city and are active in different fields.
