Translation guide
In Japanese, the concept of a childhood friend is most commonly expressed with the word 幼なじみ (osananajimi). This term carries a warm, nostalgic nuance and often implies a deep, long-standing bond. It can be used for friends of any gender, though in romantic contexts it may suggest a special closeness. There are also more specific or formal terms depending on the context.
Referring to a friend one has known since early childhood, typically with a sense of closeness and shared history.
The standard, warm term for a childhood friend. It is widely used in everyday conversation and carries a nostalgic, affectionate tone. Can be used for both male and female friends.
He is my childhood friend.
I met my childhood friend for the first time in a long time.
A slightly more literal term meaning 'childhood friend'. It is less common than 幼なじみ but still understood. It can feel a bit more formal or descriptive.
She is my childhood friend.
A literary or poetic expression for a childhood friend, literally 'friend of the bamboo horse' (referring to a toy horse made of bamboo). It evokes a very nostalgic, old-fashioned image and is rarely used in modern conversation.
He and I have been friends since childhood.
Referring to a childhood friend who is also a love interest or potential romantic partner. This nuance is common in anime, manga, and dramas.
The same word is used, but context (such as blushing, awkwardness, or romantic plotlines) makes the romantic implication clear. In Japanese media, the 'childhood friend' is a classic romantic archetype.

Describing a childhood friend in a formal context, such as a speech, essay, or official document.
A more formal phrase meaning 'a friend from early childhood'. It is suitable for written language or polite speech.

A slightly more descriptive and neutral phrase, literally 'a friend from when we were little'. It can be used in both casual and semi-formal situations.
幼なじみ is gender-neutral. However, in romantic contexts, it is often used for a friend of the opposite sex. If you want to specify gender, you can say 男の幼なじみ (male childhood friend) or 女の幼なじみ (female childhood friend).
幼なじみ is the natural, everyday word. 幼友達 is less common and can sound slightly stiff or explanatory. Stick with 幼なじみ unless you want to emphasize the literal meaning of 'childhood friend'.
I suddenly started seeing my childhood friend in a romantic light.
A friend from my childhood is getting married.
