Description

From the listing uploaded by “catappult”.

The ju-jitsu, or jujutsu or jiu-jitsu (柔術, jujutsu, literally : "Flexibility art"), combines combat techniques that were developed during the Japan's feudal era by the samurai to defend themselves when they were disarmed. These techniques are sometimes classified into four main categories: atemi waza (strike techniques), nage waza (projections techniques) kansetsu-waza (dislocations techniques) and ne-waza (ground techniques). - Judo - Ju-jitsu - Goshin Jutsu - Nage no Kata - Bushido
