How to say "persistence" in Japanese

Choosing the right word
  • 耐久たいきゅうCommon
    nounCovers endurance rather than striving: the capacity of a material, machine, or the body to withstand wear, stress, or time. For persistence as determined effort it is not the word you want.
  • 不屈ふくつCommon
    no-adjective, na-adjectivePersistence in the sense of an unyielding spirit that refuses to give in to setbacks or adversity; it praises a person's fortitude rather than describing steady work on a task.
    彼かれらは不屈ふくつの抵抗ていこうをした。↗
    They made a stubborn resistance.
  • 存続そんぞくJLPT N1approx.Common
    noun, suru verb, transitive verb, intransitive verbPersistence of things rather than people: the continued existence or survival of something such as a company, tradition, or institution. It says that something carries on, not that someone keeps trying.
    その地方ちほうではその古ふるい風俗ふうぞくがなお存続そんぞくしている。↗
    The old custom is still kept up in that district.
  • 根気こんきJLPT N1approx.Common
    nounPersistence as a personal quality: patient, steady perseverance with a long or tedious task. When you mean that someone keeps at it without giving up, this is the word you want.
    この種しゅの仕事しごとには大変たいへんな根気こんきが必要ひつようとされる。↗
    This sort of work calls for a lot of patience.
  • 持久じきゅうCommon
    noun, suru verbReally a word of endurance: the lasting power to keep going through a prolonged contest or struggle. For persistence as determined effort it is seldom the word you want; think stamina rather than grit.

For persistence as patient personal effort use 根気; for unyielding spirit in the face of adversity 不屈; for something's continued existence 存続; 耐久 and 持久 are endurance words — durability and stamina — not effort.
