Finding a Doctor in Japan
For viral sore throats that persist, or suspected strep, visit either an internal medicine clinic (内科, *naika*) or an ENT specialist (耳鼻咽喉科, *jibiin'ōkōka*). ENT clinics are particularly good for throat examination and strep testing.

FAQ
Q: How do Japanese doctors test for strep throat?
A: Japanese clinics use a rapid antigen test (溶連菌迅速検査, *yōrenkin jinsoku kensa*) that gives results in 5–10 minutes. The doctor swabs the back of your throat. If positive, antibiotics (usually amoxicillin or cephalosporin) are prescribed.
Q: What is Isodine gargle and should I use it?
A: Isodine (イソジン) is a povidone-iodine gargling solution, available at all pharmacies. It is a genuine antimicrobial that reduces viral and bacterial load in the throat. Japanese people gargle after returning indoors as a preventive measure. It is not a treatment for established infection but is genuinely protective.
Q: Can I get penicillin without a prescription in Japan?
A: No. All antibiotics require a prescription in Japan. This is appropriate — taking unprescribed antibiotics contributes to antibiotic resistance and can cause side effects including allergic reactions.
Q: Will a doctor prescribe antibiotics for a sore throat in Japan?
A: Japanese doctors are relatively conservative about antibiotic prescribing. They typically test for strep before prescribing. If the strep test is negative, they usually recommend symptomatic treatment and wait-and-see, consistent with international guidelines.
Q: Is gargling with salt water effective?
A: Yes, to some extent. Warm salt water gargling (saltwater rinse) reduces throat inflammation and can remove some surface bacteria and debris. Mix about 1/4 teaspoon of salt in 1 cup of warm water. Gargle for 30 seconds and spit.
Q: My tonsils are very large — should I worry?
A: Swollen tonsils during an active infection are normal. Persistently enlarged tonsils, especially if they are causing snoring, breathing difficulty, or repeated infections, may warrant ENT evaluation for possible tonsillectomy.
