Another very underrated Martial Art is Kodokan Judo. Thanks to BJJ has been brought to light. The BJJ Guys on here can write more than me on BJJ. On 24 July 1905 representatives of the Leading Ju Jutsu (Ryus) of Japan, gathered at the Butokukai Institute in Kyoto to agree upon the forms(Kata) of Kodokan Judo. Aincient techniques of each school to be preserved in Kata. from a technical point of view Judo has atemi wazs(striking) and Katame-waza(grappling) from the Tenjin Shinyo School and the Nage-waza from the Kito school. Both school Jigaro Kano was trained in. He took out what he considered not suited to his new system as he wanted a way of moral education as well as Fighting. I always liked to learn the History of any system i learned or practised. Not just learning techniques.. A lot of people do not realize that there are Atemi waza striking in Judo in Kata. Such as Kime-no-Kata or Goshin jutsu
