根性

• 読み: こんじょう
• ローマ字: konjō
• 漢字の分解: 根 (root) + 性 (nature/character) → one's fundamental spirit and grit
• 発音: /koɴ.dʑoː/

意味

Guts, willpower, and the spirit to push through adversity — an old-school Japanese value of perseverance through sheer determination.

The embodiment of the Japanese 'ganbaru' spirit taken to its extreme. 根性 evokes images of sports anime heroes pushing through pain, strict club activities, and the belief that willpower can overcome any obstacle. While still admired, the 根性論 (theory of guts) is increasingly debated as younger generations question whether 'just try harder' is always healthy advice. It is now used semi-ironically in situations where stubbornness or endurance is needed.

例文

1. 根性だけで乗り切った部活時代が懐かしい。
2. 根性あるねって褒められたけど、ただの意地だよ。
3. 根性論はもう古いって言われるけど、最後は気持ちだと思う。
