Kosen Judo

Kosen judo (高專柔道, Kōsen jūdō^?) is a variation of Kodokan judo that was developed and flourished at the Kōtō senmon gakkō (高等専門学校^?) (Kōsen (高專^?)) technical colleges in Japan in the first half of the twentieth century. Kosen judo's competition rules allow for greater emphasis of ne-waza (寝技^?, ground techniques) than typically takes place in competitive judo and it is sometimes regarded as a distinct style of judo.

Today, the term "kosen judo" is frequently used to refer to the competition ruleset associated with it that allows for extended ne-waza. Such competition rules are still used in the Nanatei Jūdō / Shichitei Jūdō (七帝柔道, Seven Imperials Judo^?) competitions held annually between the seven former Imperial universities. Similarly, there has been a resurgence in interest in Kosen judo in recent years due to its similarities with Brazilian jiu jitsu.
