Keihan Clinic, located in Otemae, Chuo Ward, Osaka City, is a clinic specializing in cancer immunotherapy established in 2013 by the medical corporation Saisei Mirai. The clinic's most distinctive feature is its wide range of immune and advanced therapies, including NK cell therapy, Hyper T/NK cell therapy, High-Intensity Focused Ultrasound (HIFU), high-dose vitamin C therapy, and electric field therapy. Treatment methods that utilize immune cells cultured and activated from the patient's own blood have attracted considerable attention as an approach to targeting tumors while minimizing physical burden. Beyond cancer treatment, the clinic also addresses anti-aging concerns, offering antioxidant care through alpha-lipoic acid therapy as well as immunotherapy for intractable conditions such as chronic fatigue syndrome, rheumatoid arthritis, and multiple sclerosis. English-speaking staff are available on-site, and both credit card and electronic payment options are accepted, creating a welcoming environment for a diverse range of patients. The facility is equipped with a parking lot and barrier-free infrastructure, ensuring convenient access for those visiting for treatment. As the clinic operates on an appointment-only basis, patients are required to make prior contact before their visit.
