Between 1546 to 1621, a man named Hayashizaki Jinsuke Minamoto Shigenobu lived in what today is considered as the Kanagawa prefecture of Japan. The Shigenobu shaped and defined the art of fighting with swords that is today known as Iaido.
Generally, the forms of Iaido are practiced by one person, although some schools teach forms and styles of two persons. Some students may initially learn with a wooden sword and / or a non-edged sword (Iaito). Students who are at a higher level, often use sharpened metal sword in practice.
Iaido teaches the practitioner to stay focused on present and react instantly to the criticality of the moment. Apart from this, they learn how to pull the sword from various positions and attacking with it quickly and efficiently.
