耳
みみ
mimi
= ear; ears
耳 (mimi) is the Japanese word for “ear” — the organ of hearing — and it anchors a surprisingly rich set of everyday expressions about listening, rumor, and musical ability. Its satisfying repetition of sounds (mi-mi) makes it one of the most memorable body-part words for new learners.
耳 refers to the ear as a body part, used in both singular and plural contexts since Japanese nouns do not inflect for number. It appears in neutral, everyday speech across all registers — you say 耳 whether talking to a friend or a doctor. Beyond the literal body part, 耳 extends into figurative territory: 耳がいい (mimi ga ii) means “to have a good ear” (for music or language), while 耳が痛い (mimi ga itai) — literally “my ears hurt” — is used idiomatically to mean “that hits close to home” or “I don’t want to hear that (because it’s true).” The phrase 耳にする (mimi ni suru) means “to happen to hear” or “to come across” information, emphasizing passive, incidental listening rather than active attention.
The double “mi” sound in mimi is easy to mispronounce by rushing — give each mora (み・み) equal length, as Japanese is a mora-timed language. A common mistake is confusing 耳 (mimi, ear) with 目 (me, eye) when learning body parts; note that 耳 has more strokes and a more complex shape, matching the ear’s more intricate structure. Learn the set phrase 耳を傾ける (mimi o katamukeru, “to lend an ear / to listen carefully”) early — it comes up in formal writing and speeches. Also watch for 耳鳴り (mimi nari), the word for tinnitus or ringing in the ears, which combines 耳 with 鳴り (nari, ringing).
The kanji 耳 is a pictograph that dates back to ancient Chinese oracle bone script. If you look at the character carefully, the horizontal strokes represent the outer ridges of the ear’s structure, and the vertical stroke running through them suggests the ear canal. It closely mirrors a simplified cross-section or front-view of a human ear. This visual origin makes 耳 one of the more intuitive kanji for beginners — unlike abstract characters, it actually looks like what it means. When used as a radical (called 耳偏, mimiben) in more complex kanji, it often relates to hearing or sound perception.

Formal / Cultural context
ご指摘はもっともですが、正直、耳が痛いです。

Your point is valid, but honestly, it hits close to home.
In Japanese culture, the ear carries strong associations with discretion and the ethics of listening. The expression 壁に耳あり障子に目あり (kabe ni mimi ari, shouji ni me ari — “walls have ears, sliding doors have eyes”) is a well-known proverb warning that private conversations can be overheard anywhere. This reflects a cultural sensitivity around what is said in shared or semi-public spaces, especially in traditional homes with thin paper walls.
Japan has a vibrant tradition of ear-cleaning (耳かき, mimi kaki) as a form of relaxation and intimacy — it is commonly depicted in literature and media as a tender act between close family members. Ear-cleaning cafés (耳かきカフェ) also became a cultural phenomenon in urban Japan, offering the service in a therapeutic context. This distinct cultural relationship with the ear as a site of comfort and care has no direct equivalent in most Western cultures.
