How to say "hill" in Japanese

Choosing the right word
  • やまJLPT N5approx.Common
    noun, counterChiefly 'mountain', but also covering hills; the common, general word when you simply mean rising land and the hill-versus-mountain distinction does not matter, as in talk of scenery or hiking.
    The air is thin at the top of a high mountain.
  • 坂さかJLPT N4approx.Common
    nounReally a slope or incline — rising or falling ground — so pick it when English 'hill' points to the sloping road or grade itself; for the hill as a landform, おか fits better.
    坂さかを下おりるときに彼女かのじょのおんぼろ自転車じてんしゃはキーキー音おとを立たてた。↗
    Her old bike squeaked as she rode down the hill.
  • おかJLPT N3approx.Common
    nounA gentle, rounded hill or stretch of rising ground, lower and softer than a mountain; the word you want for hills of the countryside, as in scenery descriptions.
    その丘おかは見晴みはらしがよい。↗
    The hill commands a fine view.
  • 高台たかだいCommon
    nounHigh ground standing well above its surroundings, often the elevated spot where a house stands overlooking the area; use it when 'hill' means the height or vantage rather than the landform itself.
  • 小山こやまCommon
    nounA small hill or knoll, literally a 'small mountain'; the natural choice when the rise is distinctly small and low, a modest bump in the landscape.
    あいつは小山こやまの大将たいしょうだった。↗
    He was the cock of the walk.

Use 「おか」 for a gentle hill in the landscape, 「やま」 when hill and mountain blur, 小山 for a small one, 高台 for high ground overlooking the area, and 坂 when you mean the slope itself.
