Shorinji Kempo (少林寺拳法 Shōrinji Kenpō)—note that the World Shorinji Kempo Organization prefers the Romanization kempo to kenpo—is a martial art form of Kempo that was invented by Doshin So (宗 道臣, 1911-1980) in 1947, who incorporated Japanese Zen Buddhism into the fighting style. This form of Kempo literally can be both a religion and a fighting form at the same time much like Shaolin kung fu, on which it is based (少林寺 is the Shaolin Monastery). Looked at from a Japanese martial arts perspective, it could be described as a combination of karate, judo, and aikijujutsu built on a Kung Fu framework, except that this art generally has no killing moves because of its respect for life. It is a form of Kempo that tries to get its practitioners to move through life doing minimal damage whenever possible.

Instructors are forbidden from making profit from their tutelage and there are no ladder-based competitions. Shorinji Kempo competition relies on paired demonstrations called embu where the accuracy, the rhythm, and the realism are noted and compared (with something like "technical" and "artistic" marks, as in gymnastics or ice skating).
Shorinji Kempo in its various incarnations has grown into a popular art form in Japan, the United States, Australia, and some European and Asian countries.
The practitioner of Shorinji Kempo is known as a Kenshi (拳士).
