J+Med on Madison (Tomonori Nakagama MD, PLLC) was established in July of 2017, with a mission to serve the unique needs of the Japanese expat community in New York. A former expat himself, Tomonori Nakagama, MD began his journey in New York in September of 2010 with a vision to ultimately establish his own private practice. With the July 1, 2023 opening of our brand new facility on Madison Avenue and 49th Street, he has done just that. Our pledge is to continue to provide meticulous care for all and to integrate multiple specialties, including family medicine, urgent care, preventive care, musculoskeletal care and acupuncture.
