Toyama-ry¨± (‘õÉ½Á÷) was born perhaps as early as 1925 at the Rikugun Toyama Gakko, or "Toyama Military Academy". By the 1970s, three separate organizations represented Toyama-ry¨± iaido: in Hokkaido, the late Yamaguchi Yuuki Sensei's Greater Japan Toyama Ryu Iaido Federation; in Kansai (Kyoto-Osaka area), the late Morinaga Kiyoshi Sensei's Greater Japan Toyama Ryu Iaido Association; and, Nakamura Sensei's All Japan Toyama Ryu Iaido Federation. Each organization was autonomous and retained its own set of forms; the Hokkaido branch even included sword versus bayonet exercises.
As a result of a somewhat limited series of movements and the relative speed at which a student may begin cutting targets with a sharp sword, Toyama Ryu has become widespread in the United States where it is easy to acquire swords. The history of the style has been strangely sugar coated from the standpoint of Imperial Japanese war atrocities.
Although popular sales literature for the schools that teach Toyama Ryu often cite the style as a type of kenjutsu, the flat footed cutting of targets calls to mind the tied up and defeated nature of the intended targets of the Toyama Ryu.
