There are several martial arts that are complementary each to another. Kendo and Iaido are two of them: one should know how to fight with other person, and the fight is done with the sword already drawn, and the same person should know how to draw the sword. Kendo and Iaido are very different and the same person can practice both martial arts to have a better undestanding of using the katana (one of the Japanese swords).
You are being presented a special feature on the practice of Iaido, the martial art of drawing swords. Iaido is based around a series of kata, or forms, which developed as swordsmen sought efficient ways of felling an opponent with a single blow. You can also watch a All-Japan Iaido Demonstration to find out more about the meaning of the kata and the philosophy behind this traditional discipline.
