How to say "daredevil" in Japanese

Choosing the right word
  • 荒武者あらむしゃ
    nounA daredevil with the image of a rough, wild warrior; it can also describe a rowdy person. Less common, it suits a headstrong type who charges into things without weighing the consequences.
  • 猪武者いのししむしゃ
    nounA foolhardy warrior in the image of a charging boar: bold to the point of recklessness. It also matches 'hotspur', and is a less common word.
  • 死生不知ししょうふち
    no-adjectiveA four-character expression for thinking nothing of one's death: the daredevil as someone indifferent to whether they live or die. Being less common, it is seldom the everyday word for a daredevil.
  • na-adjective, nounStresses the frantic, foolhardy side of 'daredevil': flinging yourself at something with total abandon. A less common word, usually written in kana alone despite being a yojijukugo.
  • 命知らずいのちしらず
    no-adjective, na-adjectiveThe broadest of these: it names recklessness or daredevilry itself, whether the quality, the act, or the reckless person. For most senses of 'daredevil', this is the word to reach for.

All five are less common; for a daredevil person or act 「命知らず」 is the broadest choice, 「がむしゃら」 stresses frantic recklessness, 荒武者 and 猪武者 evoke rough or foolhardy warriors, and 死生不知 means thinking nothing of death.
