Kenpō is the name of several Japanese martial arts.
The word kenpō is a Japanese translation of the Chinese word "quánfǎ. This term is often informally transliterated as "kempo", as a result of applying Traditional Hepburn romanization, but failing to use a macron to indicate the long vowel.
The generic nature of the term combined with its widespread, cross-cultural adoption in the martial arts community has led to many divergent definitions.
