Japanese has no single everyday word for "sister". Say いもうと (imōto) for a younger sister and あね (ane) for your own older sister. It is also called おねえさん (onēsan) and おねえちゃん (onēchan).
Meaning: a sister (noun)

Ways to say it

“sister” in Japanese
Japanese Romanization Note
いもうと imōto younger sister
あね ane older sister, your own
おねえさん onēsan older sister, someone else's or as address
おねえちゃん onēchan older sister, casual

When you talk about your own family to outsiders, use あね (ane) and いもうと (imōto). For someone else's older sister, add respect with おねえさん (onēsan).

Which one should you use?

おねえさん (onēsan) and おねえちゃん (onēchan) are also what younger siblings call their older sister directly. A younger sister is usually called by her first name.

What mistakes should you avoid?

Using いもうと for an older sister sounds wrong, because age order matters in Japanese.

Did you know?

  • The word for sisters as a group is しまい (shimai), and siblings of any kind are きょうだい (kyōdai).
