Peter Koussoulis
Sensei Peter Koussoulis is the Founder and Headmaster of Shinzenryu Aikido and the Principal Instructor of the Melbourne Aikido Dojo.
For more than twenty-five years, Peter Sensei has dedicated his life to the study, practice and full-time teaching of Aikido. His martial journey led him to live and train in Japan, where he became a direct student, personal uke and instructor under Takafumi Takeno Sensei at his dojo in Yamanashi Prefecture.
Takeno Sensei was one of the foremost students of Gozo Shioda, the founder of Yoshinkan Aikido and one of Morihei Ueshiba’s most distinguished disciples. Through this direct lineage, Morihei Ueshiba → Gozo Shioda → Takafumi Takeno → Peter Koussoulis – Peter Sensei received a traditional transmission of Yoshinkan Aikido at its highest level.
Among the greatest honours of his career was being awarded an instructor’s licence directly by Takeno Sensei, becoming the only foreign practitioner to receive this distinction. Peter regards this recognition not simply as an achievement, but as a lifelong responsibility to preserve, deepen and faithfully transmit the principles entrusted to him.
Following his years in Japan, Peter returned to Australia and founded the Melbourne Aikido Dojo. His approach to teaching has been profoundly shaped by the example of Takeno Sensei, whose quiet dedication to the continual refinement and sincere transmission of Aikido left a lasting impression on him. Since establishing the dojo, Peter has remained committed to the same philosophy: that the measure of a dojo lies not in its size, but in the quality of its practice, the depth of its instruction, and the character it helps cultivate in its students. This commitment allows him to personally teach every class and continually refine both his own understanding and the methods through which Aikido is transmitted.
Peter’s background extends beyond Aikido and into various martial arts including Judo, BJJ, Boxing, Iaido and Muay Thai. His lifelong interest in philosophy, contemplative traditions and personal development has led him to study a wide range of Eastern spiritual disciplines alongside numerous martial arts. These influences have enriched, but never replaced, the classical foundations of his Yoshinkan training.
After many years of practice, research and teaching, Peter formally established Shinzenryu Aikido (心然流) in 2019. Shinzenryu is a teaching methodology that integrates traditional Yoshinkan Aikido with breath cultivation, meditation and philosophical inquiry, creating a structured path that develops both technical excellence and personal transformation. While firmly rooted in the lineage of Morihei Ueshiba, Gozo Shioda and Takafumi Takeno, Shinzenryu continues to evolve through ongoing study, reflection and practical experience.
Today, Peter Sensei continues to teach every class at the Melbourne Aikido Dojo, where he remains deeply committed to helping students cultivate martial skill, personal character and a deeper experience of harmony through sincere and dedicated practice.
