How to say "tighten" in Japanese

Choosing the right word
  • 締めるしめるJLPT N5approx.Common
    ichidan verb, transitive verbThe basic word for physically tightening or fastening something — a belt, a screw, a knot, a lid. Use it for the plain act of making something tighter or fastening it more securely.
    離陸りりくの際さいは、シートベルトを締しめなくてはならない。↗
    You must fasten your seat belts during take-off.
  • 引き締めるひきしめるCommon
    ichidan verb, transitive verbTightening by pulling, so that something slack becomes firm and taut — muscles, the body, the face. It also covers bracing yourself or pulling yourself together.
    ウィッチヘーゼルは、乾燥かんそうさせずに毛穴けあなを引き締ひきしめます。↗
    Witch hazel tightens pores without drying skin.
  • 締め付けるしめつけるCommon
    ichidan verb, transitive verbTightening with force, so that something is squeezed or constricted — shoes or a belt that is too tight, a hard grip. It often implies uncomfortable, painful pressure, including a squeezing feeling in the chest.
    ここが締しめつけられるように痛いたみます。↗
    I have a gripping pain here.
  • 突っ張るつっぱるJLPT N1approx.Common
    godan verb, intransitive verbMatches 'tighten' when the body grows taut — muscles cramping up or going stiff. For tightening an object it is seldom the word you want; it really describes stiffness or cramping in the body.
  • 張るはるJLPT N5approx.Common
    godan verb, intransitive verb, transitive verbIts core sense is to stretch or spread, so it matches 'tighten' when skin, muscles or nerves become taut or strained. It is not the word for the act of tightening an object.
    クモがクモの巣すを張はるところを見みたことがありますか。↗
    Have you ever seen a spider spinning its web?

Use 「締める」 for physically tightening or fastening an object, 「引き締める」 for making something slack firm and taut or bracing yourself, 「締め付ける」 for squeezing or constricting, and 「突っ張る」 or 「張る」 for the body or muscles becoming stiff and taut.
