Tony Jaa was born and raised in a rural area in Surin Province to Rin (née Saipetch) and Thongdee Yeerum. He is of Kuy descent and he can speak Thai, Northern Khmer, and Kuy.
In his youth Jaa watched films by Bruce Lee, Jackie Chan and Jet Li at temple fairs, which was his inspiration to learn martial arts. He was so inspired by them that while he was doing chores or playing with friends, he would imitate the martial arts moves that he had seen, practicing in his father's rice paddy.
