Content supervised by medical professionals at Tokyo Hub Clinic.<\/em><\/p>\n\n\n\n\n\n Japan has its own unique seasonal illness patterns \u2014 influenza peaks from December through March, while summer brings hand-foot-and-mouth disease and heat-related illnesses. Whether you are dealing with a stubborn cough, high fever, body aches, or a sore throat that will not go away, our clinic provides same-week appointments in a comfortable, private hotel setting just minutes from Akasaka-mitsuke and Nagatacho stations.<\/p>\n\n\n\n Cold, flu, and fever-related illnesses encompass a wide range of symptoms. You should consider scheduling an appointment if you experience any of the following:<\/p>\n\n\n\n Even if your symptoms seem mild, early evaluation can prevent complications. What starts as a simple cold can progress to bronchitis, sinusitis, or pneumonia \u2014 especially in individuals with asthma, diabetes, or other underlying conditions.<\/p>\n\n\n\n Dr. Kamoshita’s approach combines thorough clinical evaluation with the diagnostic tools available at our clinic and partner laboratories:<\/p>\n\n\n\n Japan offers several antiviral and anti-inflammatory medications that may not be available in your home country. Dr. Kamoshita will explain each medication, its purpose, and any potential side effects in clear English before prescribing.<\/p>\n\n\n\n We understand that when you are feeling unwell, you want efficient, comfortable care without unnecessary delays. Here is what your visit will look like:<\/p>\n\n\n\n Getting sick in a foreign country adds stress to an already unpleasant situation. Here is how Tokyo Hub Clinic makes the process easier for international patients:<\/p>\n\n\n\n We strive for transparent, predictable pricing:<\/p>\n\n\n\n Cash and major credit cards are accepted. Itemized receipts are provided for every visit.<\/p>\n\n\n\n You are welcome to visit for any severity of illness. Mild colds can sometimes mask more serious conditions, and early treatment \u2014 especially for flu \u2014 is most effective when started within 48 hours of symptom onset. If you are unsure, call us and we can advise whether an in-person visit is recommended.<\/p>\n<\/details>\n\n\n\n Yes. We can perform rapid antigen tests for both influenza and COVID-19 during the same visit. Combined test kits are available, providing results for both viruses in approximately 15 minutes.<\/p>\n<\/details>\n\n\n\n Yes. Japan has broad availability of antiviral medications for influenza, including oseltamivir (Tamiflu), baloxavir (Xofluza), and others. These are most effective when started within 48 hours of symptom onset. Dr. Kamoshita will determine which antiviral is most appropriate for your case.<\/p>\n<\/details>\n\n\n\n Antibiotics are effective only against bacterial infections \u2014 they do not treat viral colds or flu. Dr. Kamoshita follows evidence-based prescribing guidelines and will prescribe antibiotics only when a bacterial infection is diagnosed or strongly suspected (e.g., bacterial sinusitis, strep throat, or pneumonia).<\/p>\n<\/details>\n\n\n\n Tokyo Hub Clinic operates on an appointment-only basis to ensure adequate time for each patient and to minimize waiting. For urgent cases, we do our best to accommodate same-day bookings \u2014 call 03-6261-7070<\/strong> as early in the day as possible.<\/p>\n<\/details>\n\n\n\nSymptoms We Treat<\/h2>\n\n\n\n
