Family Kanji: Mother, Father, Older & Younger Siblings

Learn the kanji for every family member — 母 父 兄 弟 姉 妹 — plus the crucial humble vs honorific split for talking about your family vs someone else's.

7 min read

Family vocabulary is early-stage essential, but Japanese has a twist: you use different words for your own family (humble) versus someone else's (honorific). The kanji stay the same — the readings and politeness change.

The core six

KanjiMeaningYour familySomeone else's
父father父 (chichi)お父さん (otōsan)
母mother母 (haha)お母さん (okāsan)
兄older brother兄 (ani)お兄さん (onīsan)
弟younger brother弟 (otōto)弟さん (otōtosan)
姉older sister姉 (ane)お姉さん (onēsan)
妹younger sister妹 (imōto)妹さん (imōtosan)

Why two words per person

When you talk about your own family to others, Japanese humility lowers them: chichi, haha, ani. When you ask about or refer to someone else's family, you raise them with お…さん: otōsan, okāsan, onīsan. Using otōsan for your own dad to a stranger sounds slightly childish; using chichi for someone else's dad sounds rude.

Building outward

  • 両親 (ryōshin) — parents (both).
  • 兄弟 (kyōdai) — siblings (literally older + younger brother, but used generally).
  • 姉妹 (shimai) — sisters.
  • 家族 (kazoku) — family. 祖父 (sofu) grandfather, 祖母 (sobo) grandmother.
