How to say "lasting" in Japanese

• 持続じぞくJLPT N1approx.Common
  noun, suru verb, transitive verb, intransitive verbLasting in the sense of continuation or persistence: it names the process of something continuing or being kept up over time, rather than a fixed quality. Suits growth, effort or effects that continue.
• 息の長いいきのながい
  i-adjectiveAn idiomatic adjective, literally 'long of breath', for work or effort that is sustained over a long span; it praises something carried on steadily rather than achieved quickly.
  息いきの長ながい仕事しごとになりそうだ。↗

  This is going to require a long steady effort.
• 恒久的こうきゅうてき
  na-adjectiveLasting in the sense of permanent: something intended to endure rather than be temporary. Fits permanent arrangements, structures or solutions, where the point is that no change or removal is foreseen.
  恒久こうきゅう的てきな平和へいわなど幻想げんそうに過すぎない。↗

  Permanent peace is nothing but an illusion.
• 末永いすえながい
  i-adjectiveA warm adjective for lasting far into the future, used chiefly in good wishes — that a relationship, happiness or prosperity continue for a long time. Not a neutral, technical way to say lasting.
• 永続的えいぞくてき
  na-adjectiveLasting as perpetual continuation: it stresses that something goes on indefinitely without stopping. Close to 恒久的, but the emphasis is on continuous duration rather than on simply being the opposite of temporary.

Use 持続 for lasting as ongoing continuation, 「息の長い」 for work or effort sustained over a long span, 恒久的 and 永続的 for permanent, enduring states, and 「末永い」 for warm wishes that something lasts far into the future.
