Treatment in Japan
Viral tonsillitis:
- No antibiotics are needed or appropriate
- Pain relief: acetaminophen (アセトアミノフェン) or ibuprofen (イブプロフェン)
- Gargling with warm salt water or commercially available gargle solutions (Japanese pharmacies sell many effective gargle products such as イソジン / Isodine)
- Rest and adequate hydration
- Ice chips, cold water, or ice cream can soothe severe throat pain
- Most viral tonsillitis resolves within 5–7 days
Bacterial tonsillitis (strep throat):
- Penicillin-type antibiotics are the first-line treatment globally, including in Japan
- Common prescriptions in Japan:
- Amoxicillin (アモキシシリン) 10-day course — most common
- Phenoxymethylpenicillin: less commonly used
- Clindamycin or macrolides (azithromycin, clarithromycin) for penicillin-allergic patients
- It is critical to complete the full 10-day antibiotic course even if you feel better after 2–3 days. Incomplete courses increase the risk of complications including rheumatic fever and peritonsillar abscess.
- Fever should begin improving within 24–48 hours of starting antibiotics

Complications to Watch For
Tonsillitis complications are rare but serious. Seek emergency care if you develop:
- Peritonsillar abscess (扁桃周囲膿瘍, *hentō-shūi nōyō*): severe one-sided throat pain, drooling, muffled "hot potato" voice, inability to open mouth fully — this requires urgent ENT evaluation and drainage
- Ludwig's angina: swelling of the floor of the mouth — rare but life-threatening
- Difficulty breathing or swallowing saliva
- Stiff neck combined with severe headache and fever (possible meningitis)
Recurrent Tonsillitis
If you have a history of recurrent bacterial tonsillitis (4+ episodes per year), tonsillectomy (扁桃摘出術, *hentō tekishutsu-jutsu*) may be recommended. This procedure is available in Japan but would not typically be arranged during a tourist visit. Discuss management with an ENT specialist.
Which Department to Visit and How to Find a Clinic
- 耳鼻咽喉科 (Jibi Inkōka) — ENT (Ear, Nose & Throat): the most appropriate specialty for tonsillitis
- 内科 (Naika) — Internal Medicine: also commonly used for throat infections, especially at neighborhood clinics
- 小児科 (Shonika) — Pediatrics: for children
ENT clinics (耳鼻咽喉科クリニック) are common throughout Japan and typically have shorter wait times than major hospital outpatient departments. Most can perform rapid strep tests on-site.

Frequently Asked Questions
Q: How do Japanese doctors decide whether to prescribe antibiotics for a sore throat?
A: Japanese ENT doctors and general practitioners typically perform a rapid strep test before prescribing antibiotics. A positive test confirms bacterial (strep) infection and warrants antibiotics. A negative test suggests a viral cause, and antibiotics are not prescribed. Japan has been actively working to reduce inappropriate antibiotic prescribing, so you should not expect antibiotics simply for requesting them.
Q: Can I buy antibiotics over the counter for a sore throat in Japan?
A: No. Antibiotics require a prescription from a licensed physician in Japan and cannot be purchased over the counter. Do not attempt to use antibiotics from another country without confirming the diagnosis with a doctor — inappropriate antibiotic use can cause harm and contribute to antibiotic resistance.
Q: How quickly should I feel better after starting antibiotics for strep throat?
A: You should notice significant improvement in fever and throat pain within 24–48 hours of starting antibiotics. By day 3–4, most people feel substantially better. However, it is essential to complete the full prescribed course (typically 10 days) even if you feel well earlier.
Q: I have peritonsillar swelling — what should I do in Japan?
A: If you have severe one-sided throat pain, inability to open your mouth fully, difficulty swallowing saliva, or a muffled voice, seek emergency ENT evaluation immediately. Peritonsillar abscess is a serious condition requiring drainage, IV antibiotics, and sometimes hospitalization. Go to a hospital emergency department rather than a neighborhood clinic.
Q: Can I eat sushi or Japanese food with tonsillitis?
A: Soft foods are recommended. Sushi rice with very soft fish (maguro, salmon) may be tolerable if chewed carefully. Avoid anything chewy, hard, spicy, or very salty until the infection resolves. Japanese rice porridge (お粥, *o-kyu*) is an ideal sore-throat food, widely available at convenience stores and restaurants.
Q: My child was diagnosed with strep throat in Japan — is the treatment the same as in my home country?
A: Generally yes. Amoxicillin (アモキシシリン) is the standard first-line treatment for strep throat in both Japan and Western countries. Dosing is based on body weight for children. Japanese pediatricians and ENT specialists are experienced in treating strep throat in children of all ages.
