Aikijutsu is an unarmed system of self-defense directly derived from swordsmanship. It is purely Japanese in origin.  In other martial arts, speed and strength are stressed in almost every situation.  Aikijutsu techniques, when done properly, will yield the same effective results regardless of speed or strength.  Most of the techniques require only a few ounces of pressure to produce spectacular results.

Aikijutsu originated in the 12th century and was passed down as a secret art within the Minamoto clan.  In the 20th century it was made public through the efforts of Takeda Sokaku (Dai Sensei) and it was known as Daito Ryū Aikijūjutsu.  There are over 30 styles of Aiki taught today.
