Nagai Clinic, located in Kikuna, Kohoku Ward, Yokohama City, Kanagawa Prefecture, is a community-based medical facility specializing in otorhinolaryngology (ENT). The clinic serves the Kikuna area with English-speaking support available, making it easier for patients whose native language is not Japanese to communicate effectively with the physician. The otorhinolaryngology department handles a wide range of conditions related to the ears, nose, and throat, from common symptoms such as hay fever, chronic sinusitis, allergic rhinitis, otitis media, tonsillitis, and hoarseness to specialized examinations and procedures. The clinic is open on weekdays and Saturdays, excluding Thursdays, Sundays, and public holidays. It is closed during the New Year period (December 29 to January 5), Golden Week (April 29 to May 5), and Obon (the week including August 14). Patients are advised to confirm the clinic schedule before visiting. Since ENT symptoms tend to become chronic, early specialist consultation is important. The clinic serves as an accessible primary care facility for patients experiencing ear, nose, or throat discomfort, supporting local healthcare in Yokohama's Kohoku Ward.
