OUR Services

Thank you for visiting the homepage of Yamaoka Clinic. We opened in Kojimachi, Tokyo. The nearest railway stations to our clinic are Kojimachi Station. We provide cares of general internal medicine, pediatrics and dermatology.
 If you are in need of these cares in English, we are ready to assist you. Living in a foreign country can be challenging with language and cultural barriers and we understand your concerns. We are willing to serve all of you living in our community.
Please do not hesitate to come and consult us when you have concerns about your body or health.
