Aikido Toho Iaido

Aikido Toho Iaido, sometimes referred as Nishio-ryu Iaido, is a style created by Shoji Nishio, a prolific Aikido practitioner. Its katas consist of 15 katas, most of which correlated to specific Aikido movements. The literal meaning of the name is iaido of Aikido form.
In 1955, due to the lack of explanation regarding sword and jo techniques from Ueshiba, Nishio started study Iaido under Shigenori Sano. He achieved 7th Dan Nihon Zenkoku Iaido Renmei.
In iaido, Nishio practiced number of different styles and consolidated what he believed to be useful. By 2001, after 46 years of learning and perfecting the art, after numerous addition and revision, he finalized his iaido system to 15 katas, most of which correlated to specific Aikido movements.
