Translation guide
The English word "milk" most commonly refers to cow's milk, but can also refer to milk from other animals or plant-based milks. In Japanese, the default word is 牛乳 for cow's milk, while ミルク is used in certain contexts like coffee or baby formula. This guide covers how to express these nuances naturally.
Referring to milk from a cow, typically consumed as a beverage or used in cooking.
The standard word for cow's milk. Use this in most everyday situations when talking about milk as a drink or ingredient.
毎朝牛乳を飲みます。
I drink milk every morning.
このケーキには牛乳が必要です。
This cake requires milk.
Often used in compound words (e.g., ミルクティー milk tea) or when referring to milk added to coffee/tea. Can also sound slightly more modern or Western. Not typically used for plain drinking milk in a Japanese home.
コーヒーにミルクを入れてください。
Please put milk in my coffee.
ミルクティーが好きです。
I like milk tea.
Referring to milk for babies, either breast milk or formula.
Specifically means breast milk. Use this when talking about breastfeeding.
母乳で育てています。
I am breastfeeding.
In the context of babies, ミルク usually refers to infant formula, not breast milk.
Referring to milk from animals other than cows, such as goats or sheep.
Use the animal name followed by の乳 (のちち or のにゅう). For example, goat milk is 山羊の乳 (やぎのちち/やぎのにゅう).
山羊の乳からチーズを作ります。
I make cheese from goat's milk.
Referring to non-dairy milk alternatives.
Commonly expressed by adding ミルク after the plant name, e.g., 豆乳 (とうにゅう) for soy milk, アーモンドミルク for almond milk. Note that 豆乳 is the standard word for soy milk and is more common than ソイミルク.
豆乳ラテを一つください。
One soy milk latte, please.
アーモンドミルクは低カロリーです。
Almond milk is low in calories.
The action of extracting milk from an animal.
The phrase 乳を搾る (ちちをしぼる) means to milk an animal. The object can be specified with の, e.g., 牛の乳を搾る.
毎朝牛の乳を搾ります。
I milk the cows every morning.
牛乳 specifically means cow's milk and is the default word for milk as a drink or ingredient. ミルク is a loanword used in certain contexts like coffee, tea, sweets, and baby formula. Using ミルク to refer to a glass of milk can sound slightly childish or like a café menu item.
While ミルク is understood, using it for plain drinking milk in a home setting may sound unnatural. Stick to 牛乳 unless you're talking about milk in coffee/tea or specific products like ミルクチョコレート.
It's time to feed the baby formula.
