|Itsutsu no Kata|
|Sub classification||Kodokan kata|
|English||Forms of five|
Itsutsu-no-kata (五の形?, "forms of five") is a kata (a set of prearranged techniques) in Judo. It consists in five techniques, known only by their number. Although popular media generally claim that it was developed by Jigoro Kano, recent scientific research has conclusively shown that the kata predates the foundation of Kodokan judo and that Jigoro Kano took it from Tenjin Shinyō-ryū jujutsu and merely imported it into judo after he made minor amendments to it. The kata is considered unfinished. However, a completed performance version of the kata, expanded to ten techniques, was recently presented under the name Tō-no-kata (十の形?, "forms of ten"). The techniques of Itsutsu-no-kata are composed of gentle movements evocative of natural forces.
