Kodokan Goshin Jutsu

Kōdōkan Goshin Jutsu or Kōdōkan goshinjutsu (講道館護身術, Kodokan skills of self-defence) is the most recent Judo kata of Kodokan and was established in 1956. Compared to Kime no kata it is a more modern set of self-defence techniques. Instead of attacks with swords, the kata contains defences against attacks with stick and pistol.

The 21 techniques are named after and grouped by ukes attack. The first two groups are unarmed attacks (toshu no bu), from close distance when uke holds toris, and from a distance when uke punches or kicks. The last three groups are attacks with weapons (buki no bu): with a dagger, a stick and with a pistol.

Most of the techniques tori uses for defence are considered illegal in judo competitions (shiai) and randori, and are therefore not known to many judoka. Beside the strikes, the wrist locks kote-hineri and kote-gaeshi belong to those techniques. Two common known aikido techniques.
