Nakazawa Otorhinolaryngology & Head and Neck Surgery Clinic, located in Iida, Kofu City, Yamanashi Prefecture, is a community-based clinic specializing in otorhinolaryngology, head and neck surgery, tracheoesophageal medicine, and allergy. One of the clinic's distinctive features is the adoption of NBI (Narrow Band Imaging) system. This technology uses specific wavelengths of light to emphasize capillaries and microstructures in the mucosal surface, proving highly effective in early detection of initial-stage cancers. When combined with a 3.2mm diameter electronic endoscope, it enables detection of cancers at stages previously difficult to identify. The clinic provides comprehensive services including laser treatment and sublingual immunotherapy for allergic rhinitis and hay fever, TRT therapy for tinnitus, sleep studies and CPAP therapy for snoring and sleep apnea syndrome, and FeNO tests for asthma diagnosis. The clinic is well-equipped with hearing tests, balance function tests, endoscopic examinations, and ultrasound examinations, offering hospital-level diagnostic capabilities in a clinic setting. Since February 2026, the clinic has also been prescribing epinephrine nasal spray (NEFFY®), an adjunctive treatment for anaphylaxis. The clinic actively embraces medical DX initiatives including electronic medical records and online eligibility verification, and accepts electronic payments such as PayPay, LINE Pay, and Alipay. With parking facilities and barrier-free design, the clinic provides an accessible environment for patients.
