Koppoujutsu (or Koppou) means attacks against bones in Japanese. Koppojutsu is commonly considered a hard art in comparison to the soft arts such as koshijutsu (attacks against muscles). Legend claims it was invented by the kappa, who excel at this discipline. It is the world's finest hand-to-hand technique, and the one who wields it is as sharp as a razor blade. It is possibly over a thousand years old and is one of the oldest japanese styles of Kenpou and which it revolved around the kanji, which means in japan today, talent or skill to understand a clever technique in little time. Here are the techniques.
