Iaido 

Iaido is the art of sword drawing. It is a modern discipline that stems from martial practices out of Japan's historic past. It is perhaps the most philosophically oriented of all Japanese budo. It is intrinsically a non-combative physical and mental discipline of the highest order based on a prescribed use of the traditional Japanese sword.

Iai-jutsu

Iai-jutsu is the art of killing on the draw. Iai-jutsu teaches how to draw quickly and in such a fashion as to negate an opponents attack with finality. Iai-jutsu is more direct and forceful than Iaido, less concerned with the state of the practitioner's mind and more with dispatching the opponent.

The very old schools of Iai-jutsu, which sword techniques were developed for combat, are either extant today or had to change their curriculum in order to remain popular and survive the modern era of budo.

Batto-do

Batto-do differs from Iaido primarily through the practice of Tameshigiri, or test-cutting with a live blade. While both Batto-do and Iaido practice Iai-kata forms, in Batto-do students are also required to demonstrate proficiency in Tameshigiri as well.
