In October 1910, a young man was killed by the Taiwanese highland aborigines in Taito-cho, Taito-gun, when they decapitated him as part of a “decapitation” ceremony. The body and head of the young man were separated.

   In October 1910, young men were killed by the Taiwanese highland aborigines in Taito-cho, Taito-gun, when they decapitated their enemies in a “decapitation” attack. The corpses of the young men were decapitated, and their limbs were bound with iron wire and steel wire. When Japan used its power as the ruling authority to forcibly suppress the Taiwanese mountain tribes, who had completely different lifestyles, conflict broke out.

    The Taiwanese mountain tribes carried out headhunting, which they called “de-cao”. They would lie in wait for their enemies and shoot them dead with guns, or they would fight them and take them down. After that, they would sever their enemies' heads with a crude sword. The mountain tribespeople would collect the severed heads and display them on a shelf. The mountain tribespeople who went out to “cut off heads” were respected as brave men in their villages.

    In 1895, Japan, having won the First Sino-Japanese War, took over Taiwan from China and began to rule it. Based on the classification system used during the Qing Dynasty, Japan divided the indigenous people into the “Pingpu” and “Koushan” tribes. The aborigines also became guerrillas in the anti-Japanese resistance movement. The Beipu Incident occurred in 1907, and the Wusha Incident broke out in 1930. In 1935, at the request of Prince Chichibu Yoshinobu, the name of the high mountain tribe was changed to “Takasago”. Japanese language functioned as a common language between the tribes of Taiwan, which had different languages. The Japanese Governor-General's Office implemented a policy of land expropriation and assimilation through police force against the Taiwanese aborigines, who were referred to as “savage tribes” under the “unowned land” theory.

      They are a minority group that accounts for about 1.9% (as of 2001) of the total population of about 22.34 million in Taiwan. The Taiwanese society is made up of about 19% aborigines out of the total population of about 22.34 million, with the majority being Han Chinese. The mountain aborigines lived in the mountains, farming and hunting, with their own unique culture. However, in recent years, due to coexistence with the majority Han Chinese, there has been an increase in migration to urban areas due to mountain development and the introduction of capitalism, and changes have occurred in their way of life and culture.
