The Japanese noun '危機 (きき)' means 'crisis'. It refers to a time of intense difficulty, trouble, or danger, often requiring immediate action or decision. This word is commonly used in contexts such as economic crises, environmental crises, or personal crises. For example: The country is facing an economic crisis「その国は経済危機に直面している」(そのくにはけいざいききにちょくめんしている). We must act quickly to avoid a crisis「危機を避けるために迅速に行動しなければならない」(ききをさけるためにじんそくにこうどうしなければならない). The word can also be used metaphorically to describe a critical turning point or moment of decision.
