Broadly yes and no . Yes , there is swearing in the original Japanese , but swearing in Japanese is a very different thing than swearing in English . It ' s both a language difference and a cultural difference . The Japanese language has many different modes of speech , some of which are considered to be rude , and merely using such a mode of speech can convey the same sort of attitudes and get the same sort of responses as swearing in English , in spite of the fact that no actual swearing as we think of it is involved . Additionally , the Japanese are generally far more conscious of reputation and respect and honor than westerners , so the broad effect and purpose of more overt and deliberate swearing can be accomplished in Japanese with words and phrases that , if translated really accurately , would strike most westerners as relatively harmless and even silly . You ' re sort of right then that that ' s not what was really written in the original Japanese , since Japanese swearing , what little there is of it , is nowhere near as overtly vulgar as American swearing . But the intent is generally still the same and the effect is generally still the same the swearing serves the same purposes . It ' s just that different , and cruder , terms have to be used in English in order to convey that .
