Wadokai Founder

Roy Y. Suenaka, Soke

Roy Yukio Suenaka Sensei, founder of Wadokai Aikido™, is one of contemporary budo’s most experienced practitioners and best-kept secrets. Born in Honolulu, Hawaii, Suenaka Sensei’s martial instruction began under his father, Warren Kenji Suenaka, who taught his son budo basics and carefully selected his primary martial tutors. These included such legends as Kodenkan Jiu-jitsu founder Henry Seishiro Okazaki, Kosho-ryu Kempo’s legendary James Masayoshi Mitose, judoka (and later, aikidoka) Yukiso Yamamoto, and celebrated kendoka Shuji Mikami, from whom Suenaka Sensei received a nidan (2nd degree black belt).

Suenaka Sensei began his aikido study upon Koichi Tohei’s 1953 visit to Hawaii, and continued his study directly under Founder Morihei Ueshiba O’Sensei at the Aikikai Hombu for eight years, beginning in 1961. That same year, Suenaka Sensei received an aikido menkyo kaiden (master-level proficiency) teaching certificate from O’Sensei, and became the first person to open a successful aikido dojo in Okinawa. He also commenced eight years of private study with renowned Matsumura Seito and Hakutsuru Shorin-ryu Karate-do Grandmaster Hohan Soken, receiving from him the rank of rokudan (6th degree black belt). In addition, Suenaka Sensei continued his judo and jiu-jitsu education at the Kodokan under famed Meijin Kazuo Ito, who personally sponsored Suenaka Sensei’s promotion to sandan (3rd degree black belt) in judo and jiu-jitsu.

In 1972, Suenaka Sensei relocated to Charleston, S.C., where he served as Southeastern U.S. director for Koichi Tohei’s International Ki Society until 1975, when Suenaka Sensei resigned to form the American International Ki Development and Philosophical Society (AIKDPS)™. Suenaka Sensei currently teaches Suenaka-Ha Tetsugaku-HoTM Wadokai Aikido™ and Matsumura Seito Hakutsuru Shorin-ryu Karate-do. He is author of the best-selling Complete Aikido, and in 2003 celebrated his 50th year of aikido study.


While his father supervised his early budo training, Suenaka Sensei is fortunate to have had the opportunity to train with many of contemporary budo’s most celebrated practitioners, beginning in Honolulu, Hawaii and later, in Japan and Okinawa. Suenaka Sensei brings his rich experience with these great teachers to his instruction at Suenaka School of Martial ArtsTM.

Morihei Ueshiba O’Sensei – 1883-1969

Founder of aikido, referred to even by non-aikidoka as O’Sensei, or “Great Teacher.” Combined traditional sword, spear and bayonet arts with Daito-ryu aikijiu-jitsu to develop fundamental aikido techniques. Profoundly spiritual, O’Sensei declared that “The true nature of budo is in the loving protection of all things,” and that to intentionally or maliciously harm one’s attacker is to harm oneself, all of which is contrary to nature. Recorded on film performing near-mystical feats of martial prowess. Suenaka Sensei studied under O’Sensei at the Aikikai Hombu (headquarters) in Tokyo for eight years, frequently serving as uchi deshi (live-in apprentice). In 1961, O’Sensei presented Suenaka Sensei with an aikido menkyo kaiden (master-level proficiency) teaching certificate.

Koichi Tohei – b.1920

Tohei Sensei formally broke with the Aikikai in 1971 and formed the Ki no Kenkyukai (International Ki Society), teaching his Shin-Shin Toitsu-style of aikido. Suenaka Sensei first studied with Tohei Sensei during the latter’s historic visit to Hawaii in 1953, resuming upon his arrival in Tokyo in 1961. Suenaka Sensei received an okuden (advanced inner teachings) certificate from Tohei Sensei and served as a shihan (senior instructor) for the Ki no Kenkyukai from 1971 until 1975, as well as and Southeastern U.S. director from 1972 to 1975, whereupon he resigned to form the American International Ki Development and Philosophical Society (AIKDPS)™.
