Jujutsu, also known as JuJitsu is a Japanese martial art form. It is a 2500 year old unarmed combat discipline, however the exact date of its development is hard to trace. Basically, jujutsu consists of grappling techniques. Although jujutsu is not a popular martial form, however famous judo is a direct form of jujutsu. Before the development of jujitsu, there were several other Japanese combat techniques, such as Kogusoku, yawara, kumiuchi, and hakuda etc, which were collectively known as Sengoku Jujutsu. Then came the modern Nihon Jujutsu, which is classified under Edo Jujutsu or the true unarmed Japanese combat system.
