This phrase is an affectionate expression used to tell an older sister that you love her very much.

Which one should you use?

While it might be tempting to use words for deep, romantic love, using 大好き (daisuki) is a much more common and natural way for siblings to express affection to one another.

The expression お姉ちゃん大好き is informal and affectionate. The use of the suffix -chan makes it suitable for use between siblings.

How do you pronounce it?

oneechan daisuki

Did you know?

  • In Japanese, you can use お姉ちゃん to address any older female peer or mentor, even if you are not biologically related.
  • In Japan, many people call their older sister by a title rather than her actual name. Using the name 'Hana' instead of お姉ちゃん might actually sound distant or cold to a sibling.
  • The kanji for 'big' in 大好き is 大, which also means 'great' or 'vast'. It acts as an intensifier to turn 'like' into 'love'.
