Because Americans don't know the difference between the two.
Kung Fu is a Chinese fighting style.
Kung Fu is Chinese, a lot of people mistake it for being Japanese because Japan once colonized China.
The word Ninja is Japanese. Nin忍(stealth,paitient) and ja者(man). During tang dynasty China when Mongolians invaded Beijing some Chinese generals and monks escaped by boat to east and landed in japan. It is said that a samurai met a chinese monk in the mountains of Iga and the monk thought the samurai a whole new fighting style in secret. This was called Ninjutsu. Nin忍(steath,perseverance)Jutsu術(The way,The art). Thats why the ninja had chinese influence. For example Dim mak(pressure points) are normally seen in kung fu movies. The ninja learned Dim Mak as well to kill opponents in 1 touch. Thats why Ninjutsu has Dim mak. The Ninja also borrowed stealth tactics from the famous chinese general Sun Tsu Many kung fu movies have mistakes normally the ones made by westerners. As seen in many movies a worrier dressed in black clothing which appears to be a ninja doing kung fu. That's a common mistake found in movies.
cuz they were asians This is because the throwing star actually originated in China. Chinese Kung Fu encompasses many arts and even Ninjitsu can be traced back to China.
Bruce studied a style of Chinese kung fu named Wing Chun. The Chinese don't traditionally use belts, that is a Japanese style.
no that is a stereotype, just like chinese people ride pandas to school. China's national martial arts is Kung fu and karate is Japanese.
