The Iaido, among the Japanese martial arts, represents the purest spirit of the soul of the Samurai. It is based on the techniques of fast sword extraction and cutting. The philosophical principle of the Iaido can be represented by the maxim "Saya no Uchi", that is the ability to win without drawing the sword. The Iaido in fact starting from techniques and tactics of victory in combat, reacting to a sudden attack (for this reason the sword is still in the sheath), it works for a constant inner improvement of the practitioner. There are many Iaido schools present and active today. Iaido Club Bangkok deals with the promotion of the Ancient Schools or Koryu, that is, the original schools of the Japanese samaurai, differing in this from the modern schools of Iaido, developed after the Second World War and closely linked to the practice of Kendo. The main Koryu practiced within Iaido Club Bangkok is Hoki Ryu, a prestigious Koryu, considered among the three main schools of Iaido in Japan. The form practiced adheres to the version defined as Nakazono Ha which has its greatest technical reference in Kumai Sensei.
