noun
A formal term for surrender or giving in, often used in political or military contexts. Less common than 降伏 (こうふく) in everyday Japanese.
その国は無条件のカピチュレーションを受け入れた。
The country accepted unconditional capitulation.
降伏 is the standard Japanese word for surrender, used in both formal and everyday contexts. カピチュレーション is a rarer, more formal loanword with a similar meaning.
Borrowed from English 'capitulation', ultimately from Latin 'capitulum' (little head, chapter).
