ひゃくせん
noun
many battles; a hundred fights
1. many battles; a hundred fights
A literary expression meaning 'a hundred battles' or, more broadly, 'many encounters or contests'. Used almost exclusively in fixed phrases and compounds.

Literary noun composed of (ひゃく) (hundred) + (せん) (battle). Almost never used alone in modern Japanese — instead appears in fixed expressions, especially the compound 百戦(ひゃくせん)錬磨(れんま) and the proverb quoted in example 2.

FIXED EXPRESSIONS:

  • 百戦(ひゃくせん)錬磨(れんま): hardened by many battles; battle-tested; veteran
  • 百戦(ひゃくせん)百勝(ひゃくしょう): a hundred battles, a hundred victories (undefeated)
  • 百戦(ひゃくせん)(あや)うからず: never in danger even in a hundred battles

CULTURAL CONTEXT:
The most common modern use is metaphorical — 百戦(ひゃくせん)錬磨(れんま) describes seasoned professionals (negotiators, salespeople, athletes), not literal soldiers.
