Tetsuro Nariyama (成山哲郎 born November 21, 1947) is a Japanese aikido teacher, the technical director of the Japan Aikido Association and chief instructor (Shihan) of the Shodokan Hombu Dojo in Osaka, Japan.
He was appointed to the latter position by the creator of this style Kenji Tomiki, one of Morihei Ueshiba's first uchi-deshi. At 8th Dan he is the highest-ranking Shodokan instructor in the world and travels internationally to teach aikido.
In addition to his studies with Kenji Tomiki he lived as uchideshi to Hirokazu Kobayashi for six years effectively learning aikido from the founder of aikido Morihei Ueshiba's first and last generation deshi. During that time he introduced Tomiki's randori method to university aikido clubs under Kobayashi's control.
He has co-authored the book Aikido Tradition and the Competitive Edge with Fumiaki Shishida.[1]
