The Southwest Kendo & Iaido Federation (SWKIF) was originally a regional kendo federation of the Kendo Federation of the United States, but in 1995, the All United States Kendo Federation was formed as a merger between the Kendo Federation of the United States and the Beikoku Kendo Renmei. As a result of this merger, the Southwest Kendo & Iaido Federation is now a regional Kendo federation of the All United States Kendo Federation. The Southwest Kendo & Iaido Federation covers the states of Arizona, Arkansas, Colorado, Louisiana, Nebraska, New Mexico, Oklahoma, South Dakota, Texas and Utah.
The All United States Kendo Federation (AUSKF) is the internationally recognized kendo federation for the United States. It is organized into various regional federations with both the Southwest Kendo & Iaido Federation and the Southern United States Kendo & Iaido Federation covering the state of Texas. The All United States Kendo Federation is dedicated to the promotion of kendo and iaido, providing seminars, rank promotions, regional and national tournaments, and the selection of the National Team represented at the World Kendo Championships.
The All United States Kendo Federation is affiliated with the International Kendo Federation (FIK), which has sponsered the World Kendo Championships every three years since 1970. The International Kendo Federation is organized into three zones: the Asia Zone, the Americas Zone, and the European Zone.
