Ear pain (耳の痛み, *mimi no itami*) is a surprisingly common complaint among tourists in Japan. Long-haul flights cause pressure-related ear discomfort, Japan's famous onsen (hot spring) and swimming pool culture creates conditions for swimmer's ear, and upper respiratory infections routinely spread to the middle ear. Japan has excellent ENT (ear, nose, and throat) clinics throughout the country, and most are accessible as walk-in patients.
Common Causes of Ear Pain in Japan
Otitis externa (swimmer's ear, 外耳炎 *gaiji-en*) — infection or inflammation of the outer ear canal. Common after onsen bathing, swimming, and excessive ear cleaning with cotton buds. Causes pain when the outer ear is touched or pulled, itching, and discharge.
Otitis media (middle ear infection, 中耳炎 *chūji-en*) — bacterial or viral infection of the middle ear, often following an upper respiratory infection (cold). Classic symptoms: deep ear pain, hearing reduction, fullness sensation, and sometimes fever. Very common in children but also affects adults.
Barotrauma (気圧外傷) — pressure change during airplane ascent or descent causes pain and sometimes rupture of the eardrum. Particularly painful when descending. Swallowing, yawning, and Valsalva maneuver (pinching the nose and gently blowing) equalize pressure.
Eustachian tube dysfunction — the tube connecting the middle ear to the throat can become blocked during a cold or allergy, causing ear fullness, pain, and muffled hearing.
Impacted earwax (耳垢栓塞 *jiko sensoku*) — excessive earwax that becomes impacted. Can worsen after getting water in the ears during onsen bathing. Causes hearing reduction and dull ear pain.
Temporomandibular joint (TMJ) pain — jaw joint dysfunction refers pain to the ear. Common in people who grind their teeth, which can worsen during travel stress.
Foreign body — rare in adults but occurs, particularly after water entry into the ear.
Referred pain — dental infections, throat infections (tonsillitis, pharyngitis), and neck problems can all cause pain felt in the ear.
Japan's Onsen and Ear Risks
Japan's onsen culture is a beloved part of travel, but soaking in hot mineral water and submerging the head can introduce water and bacteria into the ear canal, particularly in individuals who have:
- Pre-existing ear tube problems
- A perforated eardrum
- Excessive earwax buildup
- Recent ear surgery
Many onsen specifically prohibit submerging the head (頭を湯に浸けないでください). This rule exists partly for hygiene and partly to reduce ear infection risk. Follow these guidelines.
