Nippon Kempo
From a technical point of view, Nippon Kempo is a martial art system based on techniques of striking and kicking, ("atemi-waza"), blocking ("uke-waza"), throwing ("nage-waza"), reverse joint locks ("kansetsu-gyakutori-waza") and ground combat ("ne-waza"). It uses techniques derived from other arts including judo, jujutsu and karate.
