  • Director introduction



Sobajima Clinic provides regenerative medicine based on clinical experience and scientific evidence. We are also working to further develop treatments by collaborating with experts and researchers across the country.
Our hospital is equipped with state-of-the-art equipment and highly skilled staff, and we strive every day to provide the best treatment tailored to each patient’s condition. In addition, one of the major features of our hospital’s regenerative medicine is that we perform regenerative medicine that utilizes fresh cells. By using fresh cells immediately after collection, higher efficacy can be expected.
We will propose the best treatment for the problems you are currently facing, so if you are suffering from chronic symptoms or diseases, or if you have received regenerative medicine at another hospital but have not experienced the effects. If you do not have one, please feel free to contact our hospital.
