The publication of Le Non-Faire in 1973 marked the beginning of a prolific decade of writing for Itsuo Tsuda, a philosopher who spent his life bridging Eastern practices and European thought. His work introduced the regenerative movement and concepts concerning Ki to a broad audience, establishing a legacy that continues through European dōjōs.
Early Life and Education
Born in 1914 in Busan, Tsuda lived under the jurisdiction of the Empire of Japan. At age sixteen, he left his family home to escape expectations of managing the family estate. This period of wandering served as his search for philosophical frameworks. In 1934, he travelled to France, where he remained until 1940, studying under Marcel Granet and Marcel Mauss. This early exposure to French intellectual life preceded his eventual return to Japan.

After returning to his home country, Tsuda engaged in rigorous study under established masters. He pursued Noh theatre arts with Hosada. Concurrently, he trained in Seitai under Haruchika Noguchi and practiced aikido with Morihei Ueshiba. These disciplines formed the foundation of the physical and intellectual practices he later disseminated in Europe.
Return to Europe and Teaching
In 1970, Tsuda moved back to Europe to promote the katsugen undō, or regenerative movement, alongside his philosophical views on Ki. He established his primary dōjō in Paris, naming it L'Ecole de la Respiration. This site became the base for his instruction in aikido and Seitai until his death in 1984. He was subsequently buried at the Père-Lachaise Cemetery in Division 90.
Literary Output
Tsuda authored numerous volumes exploring his practical philosophy, beginning with the 1973 release of Le Non-Faire. His bibliography includes titles such as La Voie du Dépouillement, La Science du Particulier, Un, and Le Dialogue du Silence. His works have been translated into English by publishers such as Yume Editions, ensuring his ideas on the non-doing and specific scientific inquiries remain accessible to modern readers.
