Our countermeasures against COVID-19

Unfortunately, our clinic is not registered as a cold & flu clinic due to the narrow space and the limited ventilation system. Therefore, if there are subjective symptoms, such as, fever of over 37.5℃, sore throat, cough, phlegm, etc., please contact directly with counseling service of Kanagawa Prefectural Government.
We sincerely apologize for any concern and inconvenience this has caused. Thank you very much for your understanding and cooperation.

MessageWe positively accept foreign patients who want to communicate in English.
Even nowadays, it is true that not so many Japanese health-care workers can speak English well. With experience of residing in Los Angeles for two and a half years from 2015 to 2017, I always keep in mind that English-speaking patients can talk comfortably about their conditions and receive proper medical care in our clinic. We agree with that good communication is a significant step in the appropriate treatment for our patients.
