What Does Mune ga Itai (胸が痛い) Mean?
Hiragana: むねがいたい
Romaji: mune ga itai
Literal meaning: the chest hurts
Figurative meaning: the heart aches; something is emotionally painful
The expression has two major readings.
1. Literal Physical Meaning: “My Chest Hurts”
深く息を吸うと胸が痛い。
Fukaku iki o suu to mune ga itai.
My chest hurts when I take a deep breath.
2. Figurative Emotional Meaning: “My Heart Hurts”
苦しんでいる子どもたちを見ると胸が痛い。
Kurushinde iru kodomo-tachi o miru to mune ga itai.
My heart aches when I see children suffering.
If the sentence mentions breathing, movement, injury, or bodily symptoms, it is probably physical.
If it mentions another person’s suffering, regret, guilt, separation, or a sad memory, it is probably emotional.
My chest hurts when I run.
⇒ physical pain
彼の悲しそうな顔を見ると胸が痛い。
My heart aches when I see his sad face.
⇒ emotional pain
Important: Do Not Assume Real Chest Pain Is Figurative
This article explains Japanese language, not medical diagnosis.
Sudden chest pain or discomfort that does not go away—especially with pressure, squeezing, shortness of breath, sweating, nausea, dizziness, or pain spreading to the arms, neck, jaw, stomach, or back—can require urgent medical attention.
The Core Image: Why Does 胸 Mean “Heart” or “Feelings”?
The expression contains three parts.
Literal: chest, breast
Figurative: the place of one’s feelings, thoughts, or inner mind
が (ga)
Marks 胸 as the thing experiencing the state
痛い (itai)
Literal: painful; hurts
Figurative: emotionally painful; distressing
Japanese often places emotions inside the 胸. Related words such as 胸中 mean “what one is thinking or feeling inside.” The adjective 痛い can describe both physical and mental suffering.
But in emotional expressions, English often uses heart where Japanese uses 胸. That is why 胸が痛い may naturally become “my heart hurts” or “my heart aches.”
Mune ga Itai in English: Which Translation Is Best?

The History of “Chest Pain” as an Emotional Image

An older adjective, 胸痛し (mune itashi), could describe either physical chest pain or emotional pain. A poetic example meaning emotional suffering appears in the Man’yōshū, compiled in the eighth century.
The established expression 胸が痛む is defined in modern dictionaries as feeling mental pain, worrying, or suffering emotionally.

My chest hurts / my heart aches.
胸が悪い
I feel nauseated, or something is disgustingly offensive.
