Promoted to Shihan

In March 1976, Tetsuro Nariyama became the Shihan at the JAA Kansai Honbu Dojo, the Shodokan.

Also that month, Tomiki Shihan opened what would become the central Dojo of his Shodokan style, the new Shodokan Honbu Dojo in Showacho, Osaka.

In September 1976, at Waseda University, Tokyo, Nariyama Shihan won the gold medal in the individual men's Randori competition at the 4th Kanto Shakaijin Competitive Aikido Tournament.

To mark the first anniversary of Shodokan, on the 21st March, 1977, the First All Japan Shakaijin Competitive Aikido Tournament was held in the Osaka Municipal Budokan (community martial arts hall), in the grounds of Osaka Castle.

Later, Kujiraoka Sensei, Jigoro Kano's favourite Deshi praised what he saw at the tournament as "wonderfully impressive". (Kano was the founder of Judo, and Deshi means a living-in student, or disciple.)

At this tournament, Nariyama Shihan won both the Yudansha (Black Belt) Embu and the Men's Individual Randori gold medals.

1982 Obeying Tomiki Shihan's dying wishes, he began actively spreading the Shodokan system in 1982 both in Japan and around the world.

In 1985, Nariyama became a visiting lecturer at Kokushikan University.

On June 16, 1989, the First International Competitive Aikido Tournament was held at Tenri University in Nara. This was a direct result from Nariyama Shihan's many years of overseas instruction.

Competitors from some ten countries and 20 clubs took part.

In 1992 he became a visiting lecturer in the Physical Education Department of Waseda University.

In 1995, Nariyama was appointed a visiting lecturer at the Police Academy at the Osaka Municipal Police Headquarters.

In May 1997, a party was held to celebrate the 30th Anniversary of Shodokan at the Niko Hotel in Chuoku, Osaka.

Many instructors from Japan and all over the world, took part, and a special book was published to commemorate 30 years of Shodokan Aikido.
