Japanese uses different words for sisters depending on whether you are referring to the general concept of sisters, an older sister or a younger sister. 姉妹 is used to describe the relationship or a group of sisters. To refer specifically to an older sister, use 姉 or お姉さん. To refer to a younger sister, use 妹. The loanword シスター is also used, but primarily in religious contexts for a nun or in a stylized, humorous or ironic way within pop culture.
Which one should you use?
While 姉妹 describes the state of being sisters or a group of them, it is not typically used to address a single sister directly. 姉 specifically means an older sister, whereas 妹 specifically means a younger sister. The loanword シスター differs from the native terms by being used for religious figures or in ironic pop culture settings.
Is there a formal and an informal way to say it?
When speaking about your own older sister to someone outside your family, use 姉. If you are addressing your older sister directly or referring to someone else's older sister politely, use お姉さん. When speaking about your own younger sister to people outside your family, use 妹. The term シスター is colloquial and often carries a humorous or ironic tone.
