Not sure why Shioda is considered aikido, he studied when it still was daito ryu jujutsu, never studied after the war when "it" became aikido. this is not a value judgement, Shioda is a master in his own right and modern aikido can learn from it, but i feel it should be called daito ryu aiki jujutsu or similar.
Shioda returned and studied Aikido as well, plus he called his own art Aikido, not DRAJ, and never paid the necessary fees for his students to be considered as practicing the latter.
