There are several types of "Kempo" martail art styles. Kokusai kempo,Nippon Kempo, and Shorinji Kempo.
Kokusai kempo-Founded By Master Ueki and came as a form of Kung Fu, The focus of Kokusai Kempo is free style situational defense as opposed to Shorenji's formatted situation defense.
Nippon Kempo-This is a Japanese Martial Art that engages in full-contact bouts using a full range of techniques wearing specially developed protective gear.Developed in 1932 by Muneomi Sawayama the art places an equal emphasis on striking techniques using hands and feet, immobilization and controls, projections and take-downs. Nippon Kempo is a defensive art that does not restrict students in methodology
Shorinji Kempo-I dont know much about this 1 but i do kno Shorinji Kempo teaches a wide variety of techniques, ranging from goho (hard techniques) such as kicks and punches, juho (soft techniques) such as grappling and throwing, to seiho (correcting methods) acupressure techniques for revival of unconscious persons. These three types of techniques are further divided into kogi (offensive techniques), bogi (defensive techniques), shuho (defence methods, mainly against soft techniques), tai gamae (body position), sokui ho (foot position), umpo ho (footwork), and tai sabaki (body movement).Hokei is practiced either in isolated form, or during randori (free fighting, a more literal translation being "to bring Chaos under order", which is philosophically rather different to simply fighting for its own sake).
The relationship between technique, hokei and randori is similar to that of the relationship between words, sentences and essays. A word forms the basis of the sentence, just like the technique forms the basis of hokei. The sentence forms the basis of the essay, just like hokei forms the basis of randori. In order to master the art of writing good essays, one must first have a good vocabulary (words), and how you put them together to form sentences that conveys meaning. Similarly, in order to master the art of randori, one must know how to perform techniques, and how to put them together into hokei.
