The Zen Nippon Iaidà  Renmei (ZNIR) or All Japan Iaidà  Federation (å ¨æÂ¥æÂ¬å± åÂÂéÂÂé£ç abbreviated å ¨æÂ¥å± "Zen Nichi I" or 堨屠é£ "Zen I Ren") is a national non-governmental organization in Japan, founded in 1948 by Ikeda Hayato (later Prime Minister of Japan). The ZNIR was officially formed and registered with the government on May 5, 1954, by Iaido practitioners from multiple styles. The ZNIR is Japan's oldest and largest Iaidà Â-only specialist organization. It holds yearly National Kyoto Iaidà  Event in Kyoto, Japan typically from May 3 to May 5 and Hamamatsu National Iaidà  Competition Tournament in Hamamatsu city in October. ZNIR also holds many other regional Iaidà  tournaments regularly throughout the years.
The All Japan Iaido Federation was founded in 1948, and recognized officially as an organization with the Japanese Government in 1954.
In 1956, the ZNIR established å ¨æÂ¥æÂ¬å± åÂÂéÂÂé£çÂÂÃ¥ÂÂæ³ (Zen Nippon Iaidà  Renmei Tà Âhà Â) in an effort to unify practitioners and create a common set to fairly grade each practitioner from varying styles.
ZNIR has ten Chiku Renmei (district federations):
The All Japan Iaido Federation contains multiple traditional styles, in no particular order:
Due to the varying styles in the All Japan Iaido Federation, a set of common techniques, or waza, were created in 1956 to examine a practitioner's skill in a fair manner, each borrowed from five major styles in the Federation.
This set is known collectively as "Tà Âhà Â" (Ã¥ÂÂæ³Â):
Other than the Kyoto Iaidà  Taikai(tournament) in May, the ZNIR also holds a Zenkoku Kyà Âgi Taikai in the fall of every year. Each Chiku Renmei(district) also hold their own local Iaidà  tournament and exam.
The All Japan Iaidà  Federation grants ranks similarly to other Japanese martial arts organizations, with Dan and Shà Âgà  (titles) both granted to practitioners once they reach certain levels of competency and skill.
After Mudansha (ç¡段è , no Dan), there are:
Like other martial arts organizations, Shà Âgà  (title) are granted, however they are considered to be levels or rankings similarly to Dan, and are typically granted between the various Dan levels above Roku Dan.
For example, after Roku Dan and a certain amount of time has passed, the practitioner will test for Renshi at their next grading.
