Translation guide
A callus is a hardened, thickened area of skin that forms due to repeated friction or pressure. In Japanese, the most common word is たこ, but there are also specific terms for corns, writer's bumps, and related conditions. This guide helps you choose the right expression depending on the type and location.
A thickened, hardened area of skin from repeated rubbing or pressure, often on palms or soles.
The standard, everyday word for a callus. Can be used for calluses on hands, feet, or other body parts. Often written in kana, but the kanji is 胼胝.
I got a callus on my finger from playing guitar too much.
The callus on the sole of my foot hurts.
The kanji form of たこ. Rarely used in everyday writing; mostly seen in medical or formal contexts.
I'm researching treatments for calluses.
A small, painful, hardened area of skin on the toes, often with a central core.
Specifically a corn (clavus). Unlike a general callus (たこ), a corn is usually smaller, more painful, and often found on toes. The kanji is 魚の目, literally 'fish eye', but it's commonly written in kana.
I got a corn from my new shoes.
The kanji form of うおのめ, meaning 'chicken eye'. Used in medical contexts, but rare in daily life.
A callus or bump on the finger from holding a pen or pencil.
Literally 'pen callus'. The common term for a callus that forms on the middle finger from writing. Often written in kana, but can be ペン胼胝.
When I was a student, I had a huge writer's bump.
I don't write much lately, so my writer's bump has gotten smaller.
The kanji term for a writer's callus, literally 'brush callus'. Very formal and rare.
Writer's calluses are often seen in calligraphers.
A thick, hard area on the bottom of the foot, often from walking barefoot or pressure.
Thickened, rough skin that may not be a distinct callus but is hardened from work or dryness.
A general phrase meaning 'hardened skin'. Can be used when the exact term たこ feels too specific or medical.
My palms are covered with hardened skin.
Means 'keratinized tissue' or 'dead skin cells'. Often used in beauty or skincare contexts for rough, thick skin, not necessarily a callus.
たこ is a broad term for any callus, usually not painful, caused by pressure or friction. うおのめ is a specific type of callus (corn) that is smaller, often on toes, and has a hard core that causes sharp pain when pressed. If you have a painful spot on your toe, it's likely うおのめ, not たこ.
The verb できる (to form, to appear) is commonly used with calluses, corns, and blisters. For example: たこができる (a callus forms), うおのめができる (a corn forms).
My corn hurts so much I can't walk.
For corn treatment, go to a dermatologist.
Insoles are effective for treating plantar calluses.
