Located on the second floor of Chell Noge in Naka-ku, Yokohama, Yokohama Nogezaka Clinic provides internal medicine services with English support. The clinic is closed on Wednesdays, Sundays, and national holidays. The clinic specializes in cedar pollen allergy treatment and offers subcutaneous injection of the anti-IgE antibody "Xolair® (omalizumab)" for severe patients who do not receive sufficient effects from existing oral medications, eye drops, or nasal sprays. This treatment is limited to the period from February to May and requires blood tests for allergy testing and total IgE measurement before starting. For influenza prevention, both the nasal spray FluMist and traditional subcutaneous injection vaccines are available. FluMist is suitable for those aged 2 to 18 years and is needle-free, so there is no pain. In 2025, the clinic introduced the high-precision PCR testing device "ID NOW," establishing a rapid testing system that provides results for COVID-19 and influenza types A/B in approximately 13 minutes.
