📝 Usage Notes

it’s worth one’s efforts to do something

📖 How to use it

Expresses that an action or effort has value and is rewarding.

Attaches to Attach to the dictionary form of a verb or to a noun/na-adjective stem followed by の, as in の甲斐がある. Also used with verbs in the た-form (past tense) to indicate that the effort was worthwhile.

This pattern conveys that the effort put into something was not wasted—there is a payoff. It is used when you want to emphasize that the time, energy, or sacrifice was justified by the result. For example, studying hard for an exam and passing makes the study 甲斐がある. It can be used for both past and future efforts: you can say that something will be worth it (する甲斐がある) or that it was worth it (した甲斐がある). It is also common in the form やり甲斐がある, meaning a job or task is rewarding. In more formal or written contexts, you might see 甲斐あって, meaning 'thanks to the effort'.

この仕事はやり甲斐がある。
Kono shigoto wa yarigai ga aru.
This job is rewarding.
毎日練習した甲斐があって、試合に勝てた。
Mainichi renshuu shita kai ga atte, shiai ni kateru.
Thanks to my daily practice, I was able to win the match.
長い時間かけて作った料理は、食べてもらう甲斐がある。
Nagai jikan kakete tsukutta ryouri wa, tabete morau kai ga aru.
Food that you spent a long time making is worth having someone eat it.
Not だけのことはある 甲斐がある focuses on the effort being worthwhile, often from the doer's perspective. だけのことはある means 'it is not surprising given the reputation or effort' and often implies admiration from an outside perspective. For example, '彼は練習しただけのことはある' means 'He lives up to his practice (as expected).'
Register Used in both spoken and written Japanese. It is neutral but slightly more common in written or reflective speech; in casual conversation, やり甲斐がある is very common.
