History and Mission

The Bluff Clinic traces its roots to a clinic established in 1863 at the Foreign Settlement in Yokohama. Following that several other hospitals/clinics were established but with the amalgamation of some of these facilities, the former Bluff Hospital was built on the Bluff at 82 Yamate-cho. Our present clinic now occupies this site and continues the mission of providing quality medical care meeting to our community ranging from the foreign residents as well as Japanese residents. A unique part of our mission is to provide our services in English as well as Japanese, recognising the need of many in our community for such bilingual services. Thus a comfortable and fully English speaking environment makes the Bluff Clinic many foreign residents’ ideal point of entry into the Japanese medical system.
