鋼メンタル
Meaning
Steel mentality — unbreakable mental fortitude that nothing can shake or damage.
鋼メンタル describes someone whose mental resilience is as hard as steel — they are unfazed by criticism, failure, or extreme pressure. It is the opposite of 豆腐メンタル and is used with admiration, often tinged with disbelief or envy. People who handle public backlash, intense competition, or brutal work environments without flinching are praised as having 鋼メンタル. The term borrows the dramatic imagery common in anime and manga culture.
