Dr. Kohei Yoshioka

Dr. Kohei Yoshioka is one of Japan’s most rare and exceptional clinicians — a physician board-certified in both Psychiatry and Anesthesiology, a combination that places him in a tiny subset of practitioners capable of offering the most advanced, cross-disciplinary treatments for mental health, chronic pain, and treatment-resistant conditions. Born in 1985, he graduated from Fukui University School of Medicine and completed specialist training at Tokyo Jikei University Medical School (anesthesiology) and Tokyo Musashino Hospital’s Psychiatric Medicine Research Institute (psychiatry). His clinical focus on neuromodulation — including ECT (electroconvulsive therapy) and TMS (transcranial magnetic stimulation) — together with his pioneering adoption of ketamine infusion therapy and DSR Stellate Ganglion Block for PTSD and treatment-resistant depression, positions him at the very frontier of modern psychiatric care. Beyond his clinical work, Dr. Yoshioka established comatsuna Inc. in 2020 to expand digital healthcare solutions, reflecting his vision for the future of medicine: personalised, accessible, and technology-driven. He also serves as an industrial physician for metropolitan companies and educational institutions, bridging occupational health with cutting-edge psychiatric care.
