Iaido is a Japanese sword art practised through kata that combine drawing, prescribed cuts and resheathing, with attention to precision, posture and control.

Iaido is a Japanese sword practice centred on codified forms called kata. Practitioners work alone through imagined situations using precise, controlled movements.
Kata combine drawing the sword, cutting movements, footwork and resheathing. Posture, gaze, etiquette and control of the sword are also part of the training.
Schools and lineages have their own forms and protocols. Practice may use a training sword or, depending on the practitioner’s level, the school and safety rules, a live blade. Kata do not involve direct contact between partners.
According to the All Japan Kendo Federation (AJKF), Iaido derives from Japanese sword methods that emerged during the Muromachi period (1333–1573). Many classical schools exist, each with its own forms and protocols.
The AJKF created a standardized set of kata in 1969; it now includes twelve, after additions in 1980 and 1999. In France, Iaido is a related discipline managed within France Judo by the National Committee for Kendo and Related Disciplines.
Practice emphasizes precision, awareness, composure and continuity of movement. Sword work is paired with attention to posture, etiquette and the relationship between movement and stillness.
Repeating kata aims to develop control of both body and mind. Forms, salutes and teaching methods vary among schools.
Iaido may appeal to people interested in Japanese sword traditions, kata and individual technical practice.
Regular practice is generally non-contact. Where competitions are held, judges assess the execution of forms and the practitioner’s attitude. Ask a club which sword is used and how safety is managed.
